Chapter 2. Installing and Upgrading MySQL

2.1. MySQL Installation Overview

   This chapter describes how to obtain and install MySQL. You can
   choose to install MySQL Enterprise or MySQL Community Server:
     * MySQL Enterprise is MySQL AB's commercial offering for modern
       enterprise businesses. It includes MySQL Enterprise Server and
       the services provided by MySQL Network. To install MySQL
       Enterprise, see Section 2.3, "Installing MySQL Enterprise."
     * MySQL  Community Server is for users who are comfortable
       configuring and administering MySQL by themselves. To install
       MySQL Community Server, see Section 2.4, "Installing MySQL
       Community Server."

   If you plan to upgrade an existing version of MySQL to a newer
   version rather than install MySQL for the first time, see Section
   2.4.17,  "Upgrading  MySQL,"  for  information about upgrade
   procedures  and about issues that you should consider before
   upgrading.

   If you are interested in migrating to MySQL from another database
   system, you may wish to read Section A.8, "MySQL 5.0 FAQ ---
   Migration,"  which contains answers to some common questions
   concerning migration issues.

2.2. Determining your current MySQL version

   To determine the version and release of your currently installed
   MySQL installation, there are a number of options.
     * Using a command client (mysql), the server version of the
       MySQL server to which you are connected is shown once you are
       connected. The server version information includes community
       or enterprise accordingly.
       For example, here is the output from a MySQL Community Server
       edition installed on Linux:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 6
Server version: 5.0.27-standard MySQL Community Edition - Standard (G
PL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql>
       This is an example of the output from MySQL Enterprise Server
       on Windows:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.0.28-enterprise-gpl-nt MySQL Enterprise Server (GPL
)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
     * You may also determine the version information using the
       version  variables. Both the version and version_comment
       variables contain version information for the server to which
       you are connected. Use the SHOW VARIABLES statement to obtain
       the information you want, as shown in this example:
mysql> SHOW VARIABLES LIKE "%version%";
+-------------------------+------------------------------------------
+
| Variable_name           | Value
|
+-------------------------+------------------------------------------
+
| protocol_version        | 10
|
| version                 | 5.0.27-standard
|
| version_comment         | MySQL Community Edition - Standard (GPL)
|
| version_compile_machine | i686
|
| version_compile_os      | pc-linux-gnu
|
+-------------------------+------------------------------------------
+
5 rows in set (0.04 sec)

Note
       MySQL Administrator shows the server version within the Server
       Information tab. However, only the value of version is shown.
     * The STATUS command displays the version as well as version
       comment information. For example:
mysql> STATUS;
--------------
./client/mysql  Ver 14.12 Distrib 5.0.29, for pc-linux-gnu (i686) usi

2.3. Installing MySQL Enterprise

   This section does not apply to MySQL Community Server users.

   This  section  contains  information  about  the components,
   installation and initial configuration requirements for installing
   MySQL Enterprise.

2.3.1. Overview of MySQL Enterprise Installation

   To obtain MySQL Enterprise, visit http://enterprise.mysql.com if
   you're a customer. Otherwise, visit
   http://www.mysql.com/products/enterprise/. The platforms that are
   officially  supported  for  MySQL  Enterprise  are listed at
   http://www.mysql.com/support/supportedplatforms.html.

   MySQL Enterprise Server is available for download in the form of
   Quarterly Service Pack (QSP) or Monthly Rapid Update (MRU) binary
   releases.

   To install MySQL Enterprise Server, you should use the latest
   available  Quarterly  Service  Pack  (QSP). This includes an
   accumulation of the bug fixes provided in all predecessor QSP and
   MRU releases.

   MRU releases are provided on a monthly basis and represent the
   most  current  Enterprise  Server  bug fixes. Each MRU is an
   accumulation  of  the bug fixes included in its predecessor.
   Customers should standardize on the latest MRU release only if it
   includes a needed bug fix.

2.3.2. Enterprise Server Distribution Types

   This section does not apply to MySQL Community Server users.

   Enterprise Server releases will be created for the following
   packages from the MySQL 5.0 tree:
     * mysql-enterprise: Released under a commercial license and
       includes the following storage engines: MyISAM, MEMORY, MERGE,
       InnoDB, ARCHIVE, BLACKHOLE, EXAMPLE, FEDERATED.
     * mysql-enterprise-gpl: Same as mysql-enterprise, but released
       under the GPL.
     * mysql-cluster: mysql-enterprise plus MySQL Cluster (NDB).
     * mysql-classic: Released under a commercial license, does not
       include InnoDB.
     * mysql-community: Same as mysql-enterprise-gpl, but available
       for the community, and released every 6 months.

   To  satisfy  different user requirements, we provide several
   servers. mysqld is an optimized server that is a smaller, faster
   binary. mysqld-debug is compiled with debugging support but is
   otherwise configured identically to the non-debug server.

   Each  of  these  servers  is  compiled  from the same source
   distribution, though with different configuration options. All
   native MySQL clients can connect to servers from either MySQL
   version.

2.3.3. Installing the Enterprise MySQL Server

   For Windows and Mac OS X platforms you will need to use the MySQL
   installer. For all other other platforms, you will need to use the
   TAR, Zip or native package format (RPM, Solaris PKG) pafiles to
   perform the installation.

2.3.4. Upgrading MySQL Enterprise Server

   This section does not apply to MySQL Community Server users.

   When upgrading to MySQL Enterprise from Community Server you need
   only follow the installation process to install and upgrade the
   packages to the latest version provided by MySQL Enterprise. You
   will also need to install the latest MySQL Enterprise Service Pack
   and any outstanding MySQL Hot-fix packs.

   Be aware, however, that you must take into account any of the
   changes when moving between major releases. You should also check
   the release notes (see Appendix C, "MySQL Enterprise Release
   Notes") for details on major changes between revisions of MySQL
   Enterprise Server. For details of changes in other packages in
   MySQL Enterprise, see Appendix E, "MySQL Change History."

   You should also review the notes and advice contained within
   Section 2.4.17, "Upgrading MySQL."

2.3.5. Uninstalling MySQL Enterprise

   This section does not apply to MySQL Community Server users.

   You  can uninstall MySQL Enterprise using the standard tools
   according to your operating system.

Note

   When uninstalling, any data files created are not removed. You
   will need to separately remove these files to completely remove
   MySQL from your system.

2.3.5.1. Uninstalling on Windows

   To uninstall MySQL Enterprise on Windows you should use the Add or
   Remove Programs utility located within the Control Panel.
   Uninstalling MySQL Enterprise

   Packages within MySQL Enterprise must be removed individually. You
   may also use this option to remove packages that you no longer
   want or use.

   Any data you created while MySQL Enterprise was installed will not
   be removed. You will need to separately delete this information.

2.3.5.2. Uninstalling on Linux (RPMs)

   To uninstall MySQL Enterprise on a Linux operating system that
   uses the RPM package format, you must remove each of the packages
   that  were  installed  by  the  MySQL  Enterprise  Installer
   individually.

   To do this, first obtain a list of the installed packages:
shell> rpm -q -a|grep -i mysql
mysql-docs-en-5.0.26-1
MySQL-server-standard-5.0.26-0.rhel4
mysql-connector-j-5.0.3-1
MySQL-devel-standard-5.0.26-0.rhel4
mysql-query-browser-5.0r4-1rhel4
mysql-connector-odbc-3.51.12-1
MySQL-client-standard-5.0.26-0.rhel4
mysql-administrator-5.0r4-1rhel4
mysql-gui-tools-5.0r4-1rhel4
mysql-setup-wizard-1.0-1
mysql-connector-net-1.0.7-1

   You  can remove these packages individually, or all together
   automatically, like this:
shell> rpm -q -a|grep -i mysql|xargs rpm --erase

2.4. Installing MySQL Community Server

2.4.1. Overview of MySQL Community Server Installation

    1. Determine  whether  MySQL  runs and is supported on your
       platform.  Not all platforms are equally suitable for running
       MySQL, and not all platforms on which MySQL is known to run
       are officially supported by MySQL AB. For a list of platforms
       on which MySQL Community Server runs, see Section 2.4.2,
       "Operating Systems Supported by MySQL Community Server."
    2. Choose which distribution to install.  Several versions of
       MySQL  are available, and most are available in multiple
       distribution  formats.  You  can choose from prepackaged
       distributions containing binary (precompiled) programs or
       source code. When in doubt, use a binary distribution. We also
       provide public access to our current source trees for those
       who want to see our most recent developments and to help us
       test  new  code.  To determine which version and type of
       distribution you should use, see Section 2.4.3, "Choosing
       Which MySQL Distribution to Install."
    3. Download the distribution that you want to install.  For
       download instructions, see Section 2.4.4, "How to Get MySQL."
       To  verify  the  integrity  of the distribution, use the
       instructions in Section 2.4.5, "Verifying Package Integrity
       Using MD5 Checksums or GnuPG."
    4. Install the distribution.  To install MySQL from a binary
       distribution, use the instructions in Section 2.4.7, "Standard
       MySQL Installation Using a Binary Distribution." To install
       MySQL  from  a  source  distribution or from the current
       development source tree, use the instructions in Section
       2.4.15, "MySQL Installation Using a Source Distribution."
       If  you encounter installation difficulties, see Section
       2.4.19, "Operating System-Specific Notes," for information on
       solving problems for particular platforms.
    5. Perform  any  necessary  post-installation setup.  After
       installing MySQL, read Section 2.4.16, "Post-Installation
       Setup and Testing," which contains important information about
       making sure the MySQL server is working properly. It also
       describes how to secure the initial MySQL user accounts, which
       have no passwords until you assign passwords. The information
       in this section applies whether you install MySQL using a
       binary or source distribution.
    6. Perform setup for running benchmarks (optional).  If you want
       to use the MySQL benchmark scripts, Perl support for MySQL
       must be available. See Section 2.4.21, "Perl Installation
       Notes," for more information.

   The sections immediately following this one contain necessary
   information  about choosing, downloading, and verifying your
   distribution. The instructions in later sections of the chapter
   describe how to install the distribution that you choose. For
   binary distributions, see the instructions in Section 2.4.7,
   "Standard MySQL Installation Using a Binary Distribution." To
   build MySQL from source, use the instructions in Section 2.4.15,
   "MySQL Installation Using a Source Distribution."

2.4.2. Operating Systems Supported by MySQL Community Server

   This section does not apply to MySQL Enterprise Server users.

   This section lists the operating systems on which MySQL Community
   Server is known to run.

Important

   MySQL AB does not necessarily provide official support for all the
   platforms listed in this section. For information about those
   platforms which MySQL AB officially supports, see MySQL Server
   Supported Platforms
   (http://www.mysql.com/support/supportedplatforms.html) on the
   MySQL Web site.

   We use GNU Autoconf, so it is possible to port MySQL to all modern
   systems that have a C++ compiler and a working implementation of
   POSIX  threads. (Thread support is needed for the server. To
   compile  only the client code, the only requirement is a C++
   compiler.)

   MySQL has been reported to compile successfully on the following
   combinations of operating system and thread package.
     * AIX 4.x and 5.x with native threads. See Section 2.4.19.5.3,
       "IBM-AIX notes."
     * Amiga.
     * FreeBSD 5.x and up with native threads.
     * HP-UX 11.x with native threads. See Section 2.4.19.5.2, "HP-UX
       Version 11.x Notes."
     * Linux. MySQL builds on all fairly recent Linux distributions
       with glibc 2.3. See Section 2.4.19.1, "Linux Notes."
     * Mac OS X. See Section 2.4.19.2, "Mac OS X Notes."
     * NetBSD  1.3/1.4  Intel and NetBSD 1.3 Alpha. See Section
       2.4.19.4.2, "NetBSD Notes."
     * Novell NetWare 6.0 and 6.5. See Section 2.4.13, "Installing
       MySQL on NetWare."
     * OpenBSD 2.5 and with native threads. OpenBSD earlier than 2.5
       with  the  MIT-pthreads package. See Section 2.4.19.4.3,
       "OpenBSD 2.5 Notes."
     * SCO OpenServer 5.0.X with a recent port of the FSU Pthreads
       package. See Section 2.4.19.5.8, "SCO UNIX and OpenServer
       5.0.x Notes."
     * SCO Openserver 6.0.x. See Section 2.4.19.5.9, "SCO OpenServer
       6.0.x Notes."
     * SCO UnixWare 7.1.x. See Section 2.4.19.5.10, "SCO UnixWare
       7.1.x and OpenUNIX 8.0.0 Notes."
     * SGI Irix 6.x with native threads. See Section 2.4.19.5.7, "SGI
       Irix Notes."
     * Solaris 2.5 and above with native threads on SPARC and x86.
       See Section 2.4.19.3, "Solaris Notes."
     * Tru64 Unix. See Section 2.4.19.5.5, "Alpha-DEC-UNIX Notes
       (Tru64)."
     * Windows 2000, XP, and Windows Server 2003, as well as 32-bit
       Windows  Vista.  See Section 2.4.8, "Installing MySQL on
       Windows."

   MySQL has also been known to run on other systems in the past. See
   Section 2.4.19, "Operating System-Specific Notes." Some porting
   effort might be required for current versions of MySQL on these
   systems.

   Not all platforms are equally well suited for running MySQL. How
   well a certain platform is suited for a high-load mission-critical
   MySQL server is determined by the following factors:
     * General stability of the thread library.  A platform may have
       an excellent reputation otherwise, but MySQL is only as stable
       as the thread library it calls, even if everything else is
       perfect.
     * The capability of the kernel and the thread library to take
       advantage of symmetric multi-processor (SMP) systems.  When a
       process creates a thread, it should be possible for that
       thread to run on a CPU different from the original process.
     * Multi-threading and handling of mutexes.  The capability of
       the kernel and the thread library to run many threads that
       acquire and release a mutex over a short critical region
       frequently  without  excessive  context switches. If the
       implementation of pthread_mutex_lock() does not easily yield
       CPU time, this hurts MySQL tremendously. If this issue is not
       taken care of, adding extra CPUs actually makes MySQL slower.
     * Filesystem stability and performance.  MySQL's stability and
       performance are directly affected by those of the operating
       platform's filesystem. In particular, where large tables are
       in  use,  performance  is affected by the ability of the
       filesystem to deal with large files at all and to deal with
       them efficiently.
     * Expertise with the platform.  If we know a platform well, we
       enable platform-specific optimizations and fixes at compile
       time. We can also provide advice on configuring your system
       optimally for MySQL. This is also affected by the amount of
       testing we have done internally for similar configurations, as
       well  as  by  the  number  of  users that have run MySQL
       successfully on the platform in similar configurations. If
       these  figures  are high, the likelihood of encountering
       platform-specific surprises is much smaller.

2.4.3. Choosing Which MySQL Distribution to Install

   This section does not apply to MySQL Enterprise Server users.

   When preparing to install MySQL, you should decide which version
   to use. MySQL development occurs in several release series, and
   you can pick the one that best fits your needs. After deciding
   which version to install, you can choose a distribution format.
   Releases are available in binary or source format.

2.4.3.1. Choosing Which Version of MySQL to Install

   This section does not apply to MySQL Enterprise Server users.

   The first decision to make is whether you want to use a production
   (stable)  release  or  a  development  release. In the MySQL
   development process, multiple release series co-exist, each at a
   different stage of maturity:
     * MySQL 5.1 is the current development release series.
     * MySQL 5.0 is the current stable (production-quality) release
       series. New releases are issued for bugfixes only; no new
       features are being added that could effect stability.
     * MySQL   4.1,   4.0   and   3.23   are   the  old  stable
       (production-quality) release series. MySQL 4.1 is now at the
       end of the product lifecycle. Active development and support
       for these versions has ended. Extended support for MySQL 4.1
       and 4.0 is available. According to the MySQL Lifecycle Policy
       (seehttp://www.mysql.com/company/legal/lifecycle/#policy),
       only Security and Severity Level 1 issues will still be fixed
       for MySQL 4.0 and 4.1.

   We do not believe in a complete code freeze because this prevents
   us from making bugfixes and other fixes that must be done. By
   "somewhat frozen" we mean that we may add small things that should
   not affect anything that currently works in a production release.
   Naturally, relevant bugfixes from an earlier series propagate to
   later series.

   Normally, if you are beginning to use MySQL for the first time or
   trying to port it to some system for which there is no binary
   distribution, we recommend going with the production release
   series. Currently, this is MySQL 5.0. All MySQL releases, even
   those  from  development  series, are checked with the MySQL
   benchmarks and an extensive test suite before being issued.

   If you are running an older system and want to upgrade, but do not
   want to take the chance of having a non-seamless upgrade, you
   should upgrade to the latest version in the same release series
   you are using (where only the last part of the version number is
   newer than yours). We have tried to fix only fatal bugs and make
   only small, relatively "safe" changes to that version.

   If you want to use new features not present in the production
   release series, you can use a version from a development series.
   Note that development releases are not as stable as production
   releases.

   If you want to use the very latest sources containing all current
   patches and bugfixes, you can use one of our Bazaar repositories.
   These are not "releases" as such, but are available as previews of
   the code on which future releases are to be based.

   The MySQL naming scheme uses release names that consist of three
   numbers and a suffix; for example, mysql-5.0.12-beta. The numbers
   within the release name are interpreted as follows:
     * The first number (5) is the major version and describes the
       file format. All MySQL 5 releases have the same file format.
     * The second number (0) is the release level. Taken together,
       the major version and release level constitute the release
       series number.
     * The third number (12) is the version number within the release
       series. This is incremented for each new release. Usually you
       want the latest version for the series you have chosen.

   For each minor update, the last number in the version string is
   incremented.  When  there  are  major  new features or minor
   incompatibilities with previous versions, the second number in the
   version string is incremented. When the file format changes, the
   first number is increased.

   Release names also include a suffix to indicates the stability
   level of the release. Releases within a series progress through a
   set of suffixes to indicate how the stability level improves. The
   possible suffixes are:
     * alpha indicates that the release is for preview purposes only.
       Known bugs should be documented in the News section (see
       Appendix E, "MySQL Change History"). Most alpha releases
       implement new commands and extensions. Active development that
       may involve major code changes can occur in an alpha release.
       However, we do conduct testing before issuing a release.
     * beta indicates that the release is appropriate for use with
       new  development. Within beta releases, the features and
       compatibility should remain consistent. However, beta releases
       may contain numerous and major unaddressed bugs.
       No APIs, externally visible structures, or columns for SQL
       statements will change during future beta, release candidate,
       or production releases.
     * rc indicates a Release Candidate. Release candidates are
       believed to be stable, having passed all of MySQL's internal
       testing, and with all known fatal runtime bugs fixed. However,
       the release has not been in widespread use long enough to know
       for sure that all bugs have been identified. Only minor fixes
       are added. (A release candidate is what formerly was known as
       a gamma release.)
     * If there is no suffix, it indicates that the release is a
       General Availability (GA) or Production release. GA releases
       are stable, having successfully passed through all earlier
       release  stages and are believed to be reliable, free of
       serious bugs, and suitable for use in production systems. Only
       critical bugfixes are applied to the release.

   MySQL uses a naming scheme that is slightly different from most
   other products. In general, it is usually safe to use any version
   that has been out for a couple of weeks without being replaced by
   a new version within the same release series.

   All releases of MySQL are run through our standard tests and
   benchmarks to ensure that they are relatively safe to use. Because
   the  standard  tests are extended over time to check for all
   previously found bugs, the test suite keeps getting better.

   All releases have been tested at least with these tools:
     * Our internal test suite.  The mysql-test directory contains an
       extensive set of test cases. We run these tests for every
       server binary. See Section 28.1.2, "MySQL Test Suite," for
       more information about this test suite.
     * The MySQL benchmark suite.  This suite runs a range of common
       queries. It is also a test to determine whether the latest
       batch of optimizations actually made the code faster. See
       Section 7.1.4, "The MySQL Benchmark Suite."
     * The crash-me test.  This test tries to determine what features
       the  database  supports  and  what  its capabilities and
       limitations are. See Section 7.1.4, "The MySQL Benchmark
       Suite."

   We also test the newest MySQL version in our internal production
   environment, on at least one machine. We have more than 100GB of
   data to work with.

2.4.3.2. Choosing a Distribution Format

   This section does not apply to MySQL Enterprise Server users.

   After choosing which version of MySQL to install, you should
   decide  whether  to  use  a  binary distribution or a source
   distribution. In most cases, you should probably use a binary
   distribution,  if  one  exists  for  your  platform.  Binary
   distributions are available in native format for many platforms,
   such as RPM files for Linux or PKG package installers for Mac OS X
   or Solaris. Distributions also are available as Zip archives or
   compressed tar files.

   Reasons to choose a binary distribution include the following:
     * Binary distributions generally are easier to install than
       source distributions.
     * To satisfy different user requirements, we provide several
       servers in binary distributions. mysqld is an optimized server
       that is a smaller, faster binary. mysqld-debug is compiled
       with debugging support.
       Each  of  these servers is compiled from the same source
       distribution, though with different configuration options. All
       native MySQL clients can connect to servers from either MySQL
       version.

   Under some circumstances, you may be better off installing MySQL
   from a source distribution:
     * You want to install MySQL at some explicit location. The
       standard  binary  distributions  are ready to run at any
       installation  location,  but you might require even more
       flexibility to place MySQL components where you want.
     * You want to configure mysqld to ensure that features are
       available that might not be included in the standard binary
       distributions. Here is a list of the most common extra options
       that you may want to use to ensure feature availability:
          + --with-berkeley-db (not available on all platforms)
          + --with-libwrap
          + --with-named-z-libs  (this  is done for some of the
            binaries)
          + --with-debug[=full]
     * You want to configure mysqld without some features that are
       included in the standard binary distributions. For example,
       distributions normally are compiled with support for all
       character sets. If you want a smaller MySQL server, you can
       recompile it with support for only the character sets you
       need.
     * You have a special compiler (such as pgcc) or want to use
       compiler options that are better optimized for your processor.
       Binary distributions are compiled with options that should
       work  on a variety of processors from the same processor
       family.
     * You want to use the latest sources from one of the Bazaar
       repositories to have access to all current bugfixes. For
       example, if you have found a bug and reported it to the MySQL
       development  team, the bugfix is committed to the source
       repository and you can access it there. The bugfix does not
       appear in a release until a release actually is issued.
     * You want to read (or modify) the C and C++ code that makes up
       MySQL. For this purpose, you should get a source distribution,
       because the source code is always the ultimate manual.
     * Source distributions contain more tests and examples than
       binary distributions.

2.4.3.3. How and When Updates Are Released

   MySQL  is  evolving  quite  rapidly and we want to share new
   developments with other MySQL users. We try to produce a new
   release whenever we have new and useful features that others also
   seem to have a need for.

   We also try to help users who request features that are easy to
   implement. We take note of what our licensed users want, and we
   especially take note of what our support customers want and try to
   help them in this regard.

   No one is required to download a new release. The News section
   helps you determine whether the new release has something you
   really want. See Appendix E, "MySQL Change History."

   We use the following policy when updating MySQL:
     * Enterprise  Server releases are meant to appear every 18
       months, supplemented by quarterly service packs and monthly
       rapid updates. Community Server releases are meant to appear
       2-3 times per year.
     * Releases are issued within each series. Enterprise Server
       releases  are  numbered using even numbers (for example,
       5.0.20). Community Server releases are numbered using odd
       numbers (for example, 5.0.21).
     * Binary distributions for some platforms are made by us for
       major releases. Other people may make binary distributions for
       other systems, but probably less frequently.
     * We make fixes available as soon as we have identified and
       corrected small or non-critical but annoying bugs. The fixes
       are available in source form immediately from our public
       Bazaar repositories, and are included in the next release.
     * If by any chance a security vulnerability or critical bug is
       found in a release, our policy is to fix it in a new release
       as soon as possible. (We would like other companies to do
       this, too!)

2.4.3.4. MySQL Binaries Compiled by MySQL AB

   This section does not apply to MySQL Enterprise Server users.

   As a service of MySQL AB, we provide a set of binary distributions
   of MySQL that are compiled on systems at our site or on systems
   where supporters of MySQL kindly have given us access to their
   machines.

   In addition to the binaries provided in platform-specific package
   formats, we offer binary distributions for a number of platforms
   in the form of compressed tar files (.tar.gz files). See Section
   2.4.7, "Standard MySQL Installation Using a Binary Distribution."

   The  RPM  distributions  for MySQL 5.0 releases that we make
   available through our Web site are generated by MySQL AB.

   For Windows distributions, see Section 2.4.8, "Installing MySQL on
   Windows."

   These   distributions   are   generated   using  the  script
   scripts/make_binary_distribution.

   The binaries are configured and built with the following compilers
   and options. This information can also be obtained by looking at
   the variables COMP_ENV_INFO and CONFIGURE_LINE inside the script
   bin/mysqlbug of every binary tar file distribution.

   Anyone who has more optimal options for any of the following
   configure commands can mail them to the MySQL internals mailing
   list. See Section 1.6.1, "MySQL Mailing Lists."

   If you want to compile a debug version of MySQL, you should add
   --with-debug or --with-debug=full to the following configure
   commands and remove any -fomit-frame-pointer options.

   The following binaries are built on MySQL AB development systems:
     * Linux 2.4.xx x86 with gcc 2.95.3:
CFLAGS="-O2 -mcpu=pentiumpro" CXX=gcc CXXFLAGS="-O2 -mcpu=pentiumpro

     * Linux 2.4.x x86 with icc (Intel C++ Compiler 8.1 or later
       releases):

Note
       Versions 8.1 and newer of the Intel compiler have separate
       drivers for 'pure' C (icc) and C++ (icpc); if you use icc
       version 8.0 or older for building MySQL, you need to set

2.4.4. How to Get MySQL

   This section does not apply to MySQL Enterprise Server users.

   Check our downloads page at http://dev.mysql.com/downloads/ for
   information about the current version of MySQL and for downloading
   instructions. For a complete up-to-date list of MySQL download
   mirror sites, see http://dev.mysql.com/downloads/mirrors.html. You
   can also find information there about becoming a MySQL mirror site
   and how to report a bad or out-of-date mirror.

   Our main mirror is located at http://mirrors.sunsite.dk/mysql/.

2.4.5. Verifying Package Integrity Using MD5 Checksums or GnuPG

   This section does not apply to MySQL Enterprise Server users.

   After you have downloaded the MySQL package that suits your needs
   and before you attempt to install it, you should make sure that it
   is intact and has not been tampered with. MySQL AB offers three
   means of integrity checking:
     * MD5 checksums
     * Cryptographic signatures using GnuPG, the GNU Privacy Guard
     * For RPM packages, the built-in RPM integrity verification
       mechanism

   The following sections describe how to use these methods.

   If you notice that the MD5 checksum or GPG signatures do not
   match, first try to download the respective package one more time,
   perhaps  from  another mirror site. If you repeatedly cannot
   successfully verify the integrity of the package, please notify us
   about such incidents, including the full package name and the
   download site you have been using, at webmaster@mysql.com or
   build@mysql.com. Do not report downloading problems using the
   bug-reporting system.

2.4.5.1. Verifying the MD5 Checksum

   This section does not apply to MySQL Enterprise Server users.

   After you have downloaded a MySQL package, you should make sure
   that  its MD5 checksum matches the one provided on the MySQL
   download pages. Each package has an individual checksum that you
   can verify with the following command, where package_name is the
   name of the package you downloaded:
shell> md5sum package_name

   Example:
shell> md5sum mysql-standard-5.0.68-linux-i686.tar.gz
aaab65abbec64d5e907dcd41b8699945  mysql-standard-5.0.68-linux-i686.ta
r.gz

   You should verify that the resulting checksum (the string of
   hexadecimal digits) matches the one displayed on the download page
   immediately below the respective package.

Note

   Make sure to verify the checksum of the archive file (for example,
   the .zip or .tar.gz file) and not of the files that are contained
   inside of the archive.

   Note that not all operating systems support the md5sum command. On
   some, it is simply called md5, and others do not ship it at all.
   On Linux, it is part of the GNU Text Utilities package, which is
   available for a wide range of platforms. You can download the
   source code from http://www.gnu.org/software/textutils/ as well.
   If you have OpenSSL installed, you can use the command openssl md5
   package_name instead. A Windows implementation of the md5 command
   line utility is available from http://www.fourmilab.ch/md5/.
   winMd5Sum is a graphical MD5 checking tool that can be obtained
   from http://www.nullriver.com/index/products/winmd5sum.

2.4.5.2. Signature Checking Using GnuPG

   This section does not apply to MySQL Enterprise Server users.

   Another method of verifying the integrity and authenticity of a
   package is to use cryptographic signatures. This is more reliable
   than using MD5 checksums, but requires more work.

   At MySQL AB, we sign MySQL downloadable packages with GnuPG (GNU
   Privacy  Guard).  GnuPG is an Open Source alternative to the
   well-known Pretty Good Privacy (PGP) by Phil Zimmermann. See
   http://www.gnupg.org/ for more information about GnuPG and how to
   obtain and install it on your system. Most Linux distributions
   ship with GnuPG installed by default. For more information about
   GnuPG, see http://www.openpgp.org/.

   To verify the signature for a specific package, you first need to
   obtain a copy of MySQL AB's public GPG build key, which you can
   download from http://www.keyserver.net/. The key that you want to
   obtain is named build@mysql.com. Alternatively, you can cut and
   paste the key directly from the following text:
Key ID:
pub  1024D/5072E1F5 2003-02-03
     MySQL Package signing key (www.mysql.com) <build@mysql.com>
Fingerprint: A4A9 4068 76FC BD3C 4567  70C8 8C71 8D3B 5072 E1F5

-----END PGP PUBLIC KEY BLOCK-----

   To import the build key into your personal public GPG keyring, use
   gpg --import. For example, if you have saved the key in a file
   named mysql_pubkey.asc, the import command looks like this:
shell> gpg --import mysql_pubkey.asc

   After you have downloaded and imported the public build key,
   download  your  desired  MySQL package and the corresponding
   signature, which also is available from the download page. The
   signature file has the same name as the distribution file with an
   .asc extension. For example:
   Distribution file mysql-standard-5.0.68-linux-i686.tar.gz
   Signature file    mysql-standard-5.0.68-linux-i686.tar.gz.asc

   Make sure that both files are stored in the same directory and
   then run the following command to verify the signature for the
   distribution file:
shell> gpg --verify package_name.asc

   Example:
shell> gpg --verify mysql-standard-5.0.68-linux-i686.tar.gz.asc
gpg: Signature made Tue 12 Jul 2005 23:35:41 EST using DSA key ID 507
2E1F5
gpg: Good signature from "MySQL Package signing key (www.mysql.com) <
build@mysql.com>"

   The Good signature message indicates that everything is all right.
   You can ignore any insecure memory warning you might obtain.

   See the GPG documentation for more information on how to work with
   public keys.

2.4.5.3. Signature Checking Using RPM

   This section does not apply to MySQL Enterprise Server users.

   For RPM packages, there is no separate signature. RPM packages
   have a built-in GPG signature and MD5 checksum. You can verify a
   package by running the following command:
shell> rpm --checksig package_name.rpm

   Example:
shell> rpm --checksig MySQL-server-5.0.68-0.glibc23.i386.rpm
MySQL-server-5.0.68-0.glibc23.i386.rpm: md5 gpg OK

Note

   If you are using RPM 4.1 and it shows the error (GPG) NOT OK
   (MISSING KEYS: GPG#5072e1f5) even though you have imported the
   MySQL public build key into your own GPG keyring, you need to
   import the key into the RPM keyring first. RPM 4.1 no longer uses
   your personal GPG keyring (or GPG itself). Rather, it maintains
   its own keyring because it is a system-wide application and a
   user's GPG public keyring is a user-specific file. To import the
   MySQL public key into the RPM keyring, first obtain the key as
   described in Section 2.4.5.2, "Signature Checking Using GnuPG."
   Then use rpm --import to import the key. For example, if you have
   saved the public key in a file named mysql_pubkey.asc, import it
   using this command:
shell> rpm --import mysql_pubkey.asc

   If you need to obtain the MySQL public key, see Section 2.4.5.2,
   "Signature Checking Using GnuPG."

2.4.6. Installation Layouts

   This section describes the default layout of the directories
   created by installing binary or source distributions provided by
   MySQL AB. A distribution provided by another vendor might use a
   layout different from those shown here.

   For MySQL 5.0 on Windows, the default installation directory is
   C:\Program Files\MySQL\MySQL Server 5.0. (Some Windows users
   prefer to install in C:\mysql, the directory that formerly was
   used as the default. However, the layout of the subdirectories
   remains the same.) The installation directory has the following
   subdirectories:
   Directory Contents
   bin       Client programs and the mysqld server
   data      Log files, databases
   Docs      Manual in CHM format
   examples  Example programs and scripts
   include   Include (header) files
   lib       Libraries
   scripts   Utility scripts
   share     Error message files

   Installations created from MySQL AB's Linux RPM distributions
   result in files under the following system directories:
   Directory            Contents
   /usr/bin             Client programs and scripts
   /usr/sbin            The mysqld server
   /var/lib/mysql       Log files, databases
   /usr/share/info      Manual in Info format
   /usr/share/man       Unix man pages
   /usr/include/mysql   Include (header) files
   /usr/lib/mysql       Libraries
   /usr/share/mysql     Error message and character set files
   /usr/share/sql-bench Benchmarks

   On Unix, a tar file binary distribution is installed by unpacking
   it  at  the  installation  location  you  choose  (typically
   /usr/local/mysql) and creates the following directories in that
   location:
   Directory   Contents
   bin         Client programs and the mysqld server
   data        Log files, databases
   docs        Manual in Info format
   man         Unix manual pages
   include     Include (header) files
   lib         Libraries
   scripts     mysql_install_db
   share/mysql Error message files
   sql-bench   Benchmarks

   A source distribution is installed after you configure and compile
   it.  By  default, the installation step installs files under
   /usr/local, in the following subdirectories:
   Directory     Contents
   bin           Client programs and scripts
   include/mysql Include (header) files
   Docs          Manual in Info, CHM formats
   man           Unix manual pages
   lib/mysql     Libraries
   libexec       The mysqld server
   share/mysql   Error message files
   sql-bench     Benchmarks and crash-me test
   var           Databases and log files

   Within  its  installation  directory, the layout of a source
   installation differs from that of a binary installation in the
   following ways:
     * The mysqld server is installed in the libexec directory rather
       than in the bin directory.
     * The data directory is var rather than data.
     * mysql_install_db is installed in the bin directory rather than
       in the scripts directory.
     * The header file and library directories are include/mysql and
       lib/mysql rather than include and lib.

   You can create your own binary installation from a compiled source
   distribution by executing the scripts/make_binary_distribution
   script from the top directory of the source distribution.

2.4.7. Standard MySQL Installation Using a Binary Distribution

   This section does not apply to MySQL Enterprise Server users.

   The next several sections cover the installation of MySQL on
   platforms where we offer packages using the native packaging
   format  of  the  respective platform. (This is also known as
   performing a binary installation.) However, binary distributions
   of MySQL are available for many other platforms as well. See
   Section 2.4.14, "Installing MySQL from tar.gz Packages on Other
   Unix-Like Systems," for generic installation instructions for
   these packages that apply to all platforms.

   See Section 2.4, "Installing MySQL Community Server," for more
   information on what other binary distributions are available and
   how to obtain them.

2.4.8. Installing MySQL on Windows

   This section does not apply to MySQL Enterprise Server users.

   A native Windows distribution of MySQL has been available from
   MySQL AB since version 3.21 and represents a sizable percentage of
   the daily downloads of MySQL. This section describes the process
   for installing MySQL on Windows.

Note

   If you are upgrading MySQL from an existing installation older
   than MySQL 4.1.5, you must first perform the procedure described
   in Section 2.4.8.14, "Upgrading MySQL on Windows."

   To run MySQL on Windows, you need the following:
     * A Windows operating system such as 2000, XP, Vista, or Windows
       Server 2003. Only 32-bit and 64-bit versions of Windows 2000
       and later are supported; however, 64-bit Windows Vista is not
       yet supported. Windows 95/98/ME and versions of Windows older
       than these are no longer supported.
       A Windows operating system permits you to run the MySQL server
       as a service. See Section 2.4.8.11, "Starting MySQL as a
       Windows Service."
       Generally,  you should install MySQL on Windows using an
       account that has administrator rights. Otherwise, you may
       encounter problems with certain operations such as editing the
       PATH environment variable or accessing the Service Control
       Manager.
     * TCP/IP protocol support.
     * Enough space on the hard drive to unpack, install, and create
       the databases in accordance with your requirements (generally
       a minimum of 200 megabytes is recommended.)

   For a list of limitations within the Windows version of MySQL, see
   Section F.7.3, "Windows Platform Limitations."

   There may also be other requirements, depending on how you plan to
   use MySQL:
     * If you plan to connect to the MySQL server via ODBC, you need
       a Connector/ODBC driver. See Chapter 27, "Connectors."
     * If you need tables with a size larger than 4GB, install MySQL
       on an NTFS or newer filesystem. Don't forget to use MAX_ROWS
       and AVG_ROW_LENGTH when you create tables. See Section 12.1.5,
       "CREATE TABLE Syntax."

   MySQL for Windows is available in several distribution formats:
     * Binary  distributions are available that contain a setup
       program that installs everything you need so that you can
       start the server immediately. Another binary distribution
       format contains an archive that you simply unpack in the
       installation  location  and then configure yourself. For
       details,  see Section 2.4.8.1, "Choosing An Installation
       Package."
     * The source distribution contains all the code and support
       files for building the executables using the Visual Studio
       compiler system.

   Generally speaking, you should use a binary distribution that
   includes an installer. It is simpler to use than the others, and
   you need no additional tools to get MySQL up and running. The
   installer for the Windows version of MySQL, combined with a GUI
   Configuration Wizard, automatically installs MySQL, creates an
   option file, starts the server, and secures the default user
   accounts.

Caution

   Using virus scanning software such as Norton/Symantec Anti-Virus
   on directories containing MySQL data and temporary tables can
   cause issues, both in terms of the performance of MySQL and the
   virus-scanning software mis-identifying the contents of the files
   as  containing  spam.  This is because of the fingerprinting
   mechanism used by the virus scanning software, and the way in
   which  MySQL  rapidly  updates different files, which may be
   identified as a potential security risk.

   After installing MySQL Server, it is recommended that you disable
   virus scanning on main directory (datadir) being used to store
   your MySQL table data. There is usually a system built into the
   virus  scanning  software to allow certain directories to be
   specifically ignored during virus scanning.

   In addition, by default, MySQL creates temporary files in the
   standard Windows temporary directory. To prevent the temporary
   files  also  being  scanned, you should configure a separate
   temporary directory for MySQL temporary files and add this to the
   virus scanning exclusion list. To do this, add a configuration
   option for the tmpdir parameter to your my.ini configuration file.
   For more information, see Section 2.4.8.7, "Creating an Option
   File," and tmpdir.

   The following section describes how to install MySQL on Windows
   using a binary distribution. To use an installation package that
   does not include an installer, follow the procedure described in
   Section 2.4.8.5, "Installing MySQL from a Noinstall Zip Archive."
   To install using a source distribution, see Section 2.4.15.6,
   "Installing MySQL from Source on Windows."

   MySQL  distributions  for  Windows  can  be  downloaded from
   http://dev.mysql.com/downloads/. See Section 2.4.4, "How to Get
   MySQL."

2.4.8.1. Choosing An Installation Package

   This section does not apply to MySQL Enterprise Server users.

   For MySQL 5.0, there are three installation packages to choose
   from when installing MySQL on Windows:
     * The Essentials package.  This package has a filename similar
       to mysql-essential-5.0.68-win32.msi and contains the minimum
       set of files needed to install MySQL on Windows, including the
       Configuration Wizard. This package does not include optional
       components such as the embedded server and benchmark suite.
     * The Complete package.  This package has a filename similar to
       mysql-5.0.68-win32.zip and contains all files needed for a
       complete Windows installation, including the Configuration
       Wizard. This package includes optional components such as the
       embedded server and benchmark suite.
     * The no-install archive.  This package has a filename similar
       to mysql-noinstall-5.0.68-win32.zip and contains all the files
       found in the Complete install package, with the exception of
       the Configuration Wizard. This package does not include an
       automated  installer, and must be manually installed and
       configured.

   The  Essentials package is recommended for most users. It is
   provided as an .msi file for use with the Windows Installer. The
   Complete and Noinstall distributions are packaged as Zip archives.
   To use them, you must have a tool that can unpack .zip files.

   Your choice of install package affects the installation process
   you must follow. If you choose to install either the Essentials or
   Complete install packages, see Section 2.4.8.2, "Installing MySQL
   with the Automated Installer." If you choose to install MySQL from
   the Noinstall archive, see Section 2.4.8.5, "Installing MySQL from
   a Noinstall Zip Archive."

2.4.8.2. Installing MySQL with the Automated Installer

   New MySQL users can use the MySQL Installation Wizard and MySQL
   Configuration  Wizard to install MySQL on Windows. These are
   designed to install and configure MySQL in such a way that new
   users can immediately get started using MySQL.

   The MySQL Installation Wizard and MySQL Configuration Wizard are
   available in the Essentials and Complete install packages. They
   are recommended for most standard MySQL installations. Exceptions
   include users who need to install multiple instances of MySQL on a
   single server host and advanced users who want complete control of
   server configuration.

2.4.8.3. Using the MySQL Installation Wizard

2.4.8.3.1. Introduction to the Installation Wizard

   MySQL Installation Wizard is an installer for the MySQL server
   that uses the latest installer technologies for Microsoft Windows.
   The MySQL Installation Wizard, in combination with the MySQL
   Configuration Wizard, allows a user to install and configure a
   MySQL server that is ready for use immediately after installation.

   The MySQL Installation Wizard is the standard installer for all
   MySQL server distributions, version 4.1.5 and higher. Users of
   previous versions of MySQL need to shut down and remove their
   existing MySQL installations manually before installing MySQL with
   the MySQL Installation Wizard. See Section 2.4.8.3.7, "Upgrading
   MySQL with the Installation Wizard," for more information on
   upgrading from a previous version.

   The  Microsoft  Windows  Installer (MSI) is the standard for
   application installations on Windows 2000 and later versions. The
   MySQL Installation Wizard makes use of this technology to provide
   a smoother and more flexible installation process.

   The  Microsoft Windows Installer Engine was updated with the
   release of Windows XP; those using a previous version of Windows
   can   reference   this   Microsoft  Knowledge  Base  article
   (http://support.microsoft.com/default.aspx?scid=kb;EN-US;292539)
   for information on upgrading to the latest version of the Windows
   Installer Engine.

   In addition, Microsoft has introduced the WiX (Windows Installer
   XML) toolkit, which is the first highly acknowledged Open Source
   project from Microsoft. We have switched to WiX because it is an
   Open  Source project and it allows us to handle the complete
   Windows installation process in a flexible manner using scripts.

   Improving the MySQL Installation Wizard depends on the support and
   feedback of users. If you find that the MySQL Installation Wizard
   is lacking some feature important to you, or if you discover a
   bug, please report it in our bugs database using the instructions
   given in Section 1.7, "How to Report Bugs or Problems."

2.4.8.3.2. Downloading and Starting the MySQL Installation Wizard

   MySQL   installation   packages   can   be  downloaded  from
   http://dev.mysql.com/downloads/. If the package you download is
   contained within a Zip archive, you need to extract the archive
   first.

Note

   If you are installing on Windows Vista it is best to open a port
   for MySQL to use before beginning the installation. To do this,
   first ensure that you are logged in as an administrator, then go
   to the Control Panel and double-click the Windows Firewall icon.
   Choose the Allow a program through Windows Firewall option and
   click the Add port button. Enter MySQL into the Name text box and
   3306 (or other port of your choice) into the Port number text box.
   Also ensure that the TCP protocol radio button is selected. If you
   wish, you can also limit access to the MySQL server by choosing
   the Change scope button. Confirm your choices by clicking the OK
   button. If you do not open a port prior to installation, you
   cannot configure the MySQL server immediately after installation.
   Additionally,  when running the MySQL Installation Wizard on
   Windows  Vista, ensure that you are logged in as a user with
   administrative rights.

   The process for starting the wizard depends on the contents of the
   installation package you download. If there is a setup.exe file
   present, double-click it to start the installation process. If
   there  is an .msi file present, double-click it to start the
   installation process.
   MySQL Installer Main Screen (Windows)

2.4.8.3.3. Choosing an Installation Type

   There are three installation types available: Typical, Complete,
   and Custom.
   MySQL Installer Setup type (Windows)

   The Typical installation type installs the MySQL server, the mysql
   command-line  client,  and  the  command-line utilities. The
   command-line clients and utilities include mysqldump, myisamchk,
   and several other tools to help you manage the MySQL server.

   The Complete installation type installs all components included in
   the installation package. The full installation package includes
   components such as the embedded server library, the benchmark
   suite, support scripts, and documentation.

   The Custom installation type gives you complete control over which
   packages you wish to install and the installation path that is
   used. See Section 2.4.8.3.4, "The Custom Installation Dialog," for
   more information on performing a custom install.

   If you choose the Typical or Complete installation types and click
   the Next button, you advance to the confirmation screen to verify
   your choices and begin the installation. If you choose the Custom
   installation type and click the Next button, you advance to the
   custom installation dialog, described in Section 2.4.8.3.4, "The
   Custom Installation Dialog."

2.4.8.3.4. The Custom Installation Dialog

   This section does not apply to MySQL Enterprise Server users.

   If  you wish to change the installation path or the specific
   components that are installed by the MySQL Installation Wizard,
   choose the Custom installation type.
   MySQL Installer Custom Installation (Windows)

   A tree view on the left side of the custom install dialog lists
   all available components. Components that are not installed have a
   red X icon; components that are installed have a gray icon. To
   change whether a component is installed, click on that component's
   icon and choose a new option from the drop-down list that appears.

   You can change the default installation path by clicking the
   Change... button to the right of the displayed installation path.

   After choosing your installation components and installation path,
   click the Next button to advance to the confirmation dialog.

2.4.8.3.5. The Confirmation Dialog

   This section does not apply to MySQL Enterprise Server users.

   Once you choose an installation type and optionally choose your
   installation components, you advance to the confirmation dialog.
   Your installation type and installation path are displayed for you
   to review.
   MySQL Installer Installation Summary (Windows)

   To install MySQL if you are satisfied with your settings, click
   the  Install button. To change your settings, click the Back
   button. To exit the MySQL Installation Wizard without installing
   MySQL, click the Cancel button.

   After installation is complete, you have the option of registering
   with the MySQL web site. Registration gives you access to post in
   the MySQL forums at forums.mysql.com (http://forums.mysql.com),
   along  with  the  ability  to  report bugs at bugs.mysql.com
   (http://bugs.mysql.com) and to subscribe to our newsletter. The
   final  screen  of  the  installer  provides a summary of the
   installation  and  gives  you the option to launch the MySQL
   Configuration Wizard, which you can use to create a configuration
   file, install the MySQL service, and configure security settings.

2.4.8.3.6. Changes Made by MySQL Installation Wizard

   This section does not apply to MySQL Enterprise Server users.

   Once you click the Install button, the MySQL Installation Wizard
   begins the installation process and makes certain changes to your
   system which are described in the sections that follow.

   Changes to the Registry

   The MySQL Installation Wizard creates one Windows registry key in
   a      typical     install     situation,     located     in
   HKEY_LOCAL_MACHINE\SOFTWARE\MySQL AB.

   The MySQL Installation Wizard creates a key named after the major
   version of the server that is being installed, such as MySQL
   Server 5.0. It contains two string values, Location and Version.
   The  Location  string  contains the path to the installation
   directory.  In a default installation it contains C:\Program
   Files\MySQL\MySQL Server 5.0\. The Version string contains the
   release number. For example, for an installation of MySQL Server
   5.0.68, the key contains a value of 5.0.68.

   These registry keys are used to help external tools identify the
   installed location of the MySQL server, preventing a complete scan
   of the hard-disk to determine the installation path of the MySQL
   server. The registry keys are not required to run the server, and
   if you install MySQL using the noinstall Zip archive, the registry
   keys are not created.

   Changes to the Start Menu

   The MySQL Installation Wizard creates a new entry in the Windows
   Start menu under a common MySQL menu heading named after the major
   version of MySQL that you have installed. For example, if you
   install MySQL 5.0, the MySQL Installation Wizard creates a MySQL
   Server 5.0 section in the Start menu.

   The  following entries are created within the new Start menu
   section:
     * MySQL Command Line Client: This is a shortcut to the mysql
       command-line client and is configured to connect as the root
       user. The shortcut prompts for a root user password when you
       connect.
     * MySQL Server Instance Config Wizard: This is a shortcut to the
       MySQL Configuration Wizard. Use this shortcut to configure a
       newly installed server, or to reconfigure an existing server.
     * MySQL  Documentation: This is a link to the MySQL server
       documentation that is stored locally in the MySQL server
       installation directory. This option is not available when the
       MySQL server is installed using the Essentials installation
       package.

   Changes to the File System

   The MySQL Installation Wizard by default installs the MySQL 5.0
   server to C:\Program Files\MySQL\MySQL Server 5.0, where Program
   Files is the default location for applications in your system, and
   5.0  is  the major version of your MySQL server. This is the
   recommended location for the MySQL server, replacing the former
   default location C:\mysql.

   By  default,  all  MySQL applications are stored in a common
   directory at C:\Program Files\MySQL, where Program Files is the
   default location for applications in your Windows installation. A
   typical MySQL installation on a developer machine might look like
   this:
C:\Program Files\MySQL\MySQL Server 5.0
C:\Program Files\MySQL\MySQL Administrator 1.0
C:\Program Files\MySQL\MySQL Query Browser 1.0

   This approach makes it easier to manage and maintain all MySQL
   applications installed on a particular system.

2.4.8.3.7. Upgrading MySQL with the Installation Wizard

   This section does not apply to MySQL Enterprise Server users.

   The  MySQL  Installation  Wizard can perform server upgrades
   automatically using the upgrade capabilities of MSI. That means
   you do not need to remove a previous installation manually before
   installing a new release. The installer automatically shuts down
   and removes the previous MySQL service before installing the new
   version.

   Automatic upgrades are available only when upgrading between
   installations that have the same major and minor version numbers.
   For example, you can upgrade automatically from MySQL 4.1.5 to
   MySQL 4.1.6, but not from MySQL 4.1 to MySQL 5.0.

   See Section 2.4.8.14, "Upgrading MySQL on Windows."

2.4.8.4. MySQL Server Configuration Wizard

   The MySQL Server Configuration Wizard helps automate the process
   of  configuring  your  server.  It  creates  a  custom MySQL
   configuration file (my.ini or my.cnf) by asking you a series of
   questions  and then applying your responses to a template to
   generate  the  configuration  file  that  is  tuned  to your
   installation.

   The MySQL Server Configuration Wizard is included with the MySQL
   5.0  server.  For  Community  Server users, the MySQL Server
   Configuration Wizard is available only for Windows. For Enterprise
   Server users, the MySQL Server Configuration Wizard is included as
   part of the standard Enterprise Installer.

   The MySQL Server Configuration Wizard is to a large extent the
   result of feedback that MySQL AB has received from many users over
   a period of several years. However, if you find that it lacks some
   feature important to you, please report it in our bugs database
   using the instructions given in Section 1.7, "How to Report Bugs
   or Problems."

2.4.8.4.1. Starting the MySQL Server Configuration Wizard

   The MySQL Server Configuration Wizard is normally started as part
   of the installation process. You should only need to run the MySQL
   Server Configuration Wizard again when you need to change the
   configuration parameters of your server.

   If you chose not to open a port prior to installing MySQL on
   Windows  Vista,  you  can  choose  to  use  the MySQL Server
   Configuration Wizard after installation. However, you must open a
   port in the Windows Firewall. To do this see the instructions
   given in Section 2.4.8.3.2, "Downloading and Starting the MySQL
   Installation Wizard." Rather than opening a port, you also have
   the option of adding MySQL as a program that bypasses the Windows
   Firewall. One or the other option is sufficient --- you need not
   do both. Additionally, when running the MySQL Server Configuration
   Wizard on Windows Vista ensure that you are logged in as a user
   with administrative rights.
   MySQL Server Configuration Wizard

2.4.8.4.1.1. The MySQL Server Configuration Wizard on Windows

   You can launch the MySQL Configuration Wizard by clicking the
   MySQL Server Instance Config Wizard entry in the MySQL section of
   the Windows Start menu.

   Alternatively, you can navigate to the bin directory of your MySQL
   installation and launch the MySQLInstanceConfig.exe file directly.

   The MySQL Server Configuration Wizard places the my.ini file in
   the  installation directory for the MySQL server. This helps
   associate configuration files with particular server instances.

   To ensure that the MySQL server knows where to look for the my.ini
   file, an argument similar to this is passed to the MySQL server as
   part of the service installation:
--defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini"

   Here, C:\Program Files\MySQL\MySQL Server 5.0 is replaced with the
   installation path to the MySQL Server. The --defaults-file option
   instructs  the  MySQL  server to read the specified file for
   configuration options when it starts.

   Apart from making changes to the my.ini file by running the MySQL
   Server Configuration Wizard again, you can modify it by opening it
   with a text editor and making any necessary changes. You can also
   modify the server configuration with the MySQL Administrator
   (http://www.mysql.com/products/administrator/) utility. For more
   information  about  server configuration, see Section 5.1.2,
   "Command Options."

   MySQL  clients and utilities such as the mysql and mysqldump
   command-line  clients are not able to locate the my.ini file
   located in the server installation directory. To configure the
   client and utility applications, create a new my.ini file in the
   Windows installation directory (for example, C:\WINDOWS).

   Under Windows Server 2003, Windows Server 2000 and Windows XP,
   MySQL Server Configuration Wizard will configure MySQL to work as
   a Windows service. To start and stop MySQL you use the Services
   application that is supplied as part of the Windows Administrator
   Tools.

2.4.8.4.2. Choosing a Maintenance Option

   If the MySQL Server Configuration Wizard detects an existing
   configuration file, you have the option of either reconfiguring
   your existing server, or removing the server instance by deleting
   the  configuration  file and stopping and removing the MySQL
   service.

   To  reconfigure  an existing server, choose the Re-configure
   Instance  option  and  click  the  Next button. Any existing
   configuration file is not overwritten, but renamed (within the
   same directory) using a timestamp (Windows) or sequential number
   (Linux). To remove the existing server instance, choose the Remove
   Instance option and click the Next button.

   If  you  choose the Remove Instance option, you advance to a
   confirmation window. Click the Execute button. The MySQL Server
   Configuration Wizard stops and removes the MySQL service, and then
   deletes the configuration file. The server installation and its
   data folder are not removed.

   If you choose the Re-configure Instance option, you advance to the
   Configuration  Type  dialog where you can choose the type of
   installation that you wish to configure.

2.4.8.4.3. Choosing a Configuration Type

   When you start the MySQL Server Configuration Wizard for a new
   MySQL installation, or choose the Re-configure Instance option for
   an existing installation, you advance to the Configuration Type
   dialog.
   MySQL Server Configuration Wizard: Configuration Type

   There   are  two  configuration  types  available:  Detailed
   Configuration   and  Standard  Configuration.  The  Standard
   Configuration option is intended for new users who want to get
   started with MySQL quickly without having to make many decisions
   about server configuration. The Detailed Configuration option is
   intended for advanced users who want more fine-grained control
   over server configuration.

   If  you  are  new to MySQL and need a server configured as a
   single-user developer machine, the Standard Configuration should
   suit your needs. Choosing the Standard Configuration option causes
   the MySQL Configuration Wizard to set all configuration options
   automatically with the exception of Service Options and Security
   Options.

   The Standard Configuration sets options that may be incompatible
   with systems where there are existing MySQL installations. If you
   have an existing MySQL installation on your system in addition to
   the installation you wish to configure, the Detailed Configuration
   option is recommended.

   To  complete the Standard Configuration, please refer to the
   sections  on Service Options and Security Options in Section
   2.4.8.4.10, "The Service Options Dialog," and Section 2.4.8.4.11,
   "The Security Options Dialog," respectively.

2.4.8.4.4. The Server Type Dialog

   There are three different server types available to choose from.
   The server type that you choose affects the decisions that the
   MySQL Server Configuration Wizard makes with regard to memory,
   disk, and processor usage.
   MySQL Server Configuration Wizard: Server Type
     * Developer Machine: Choose this option for a typical desktop
       workstation where MySQL is intended only for personal use. It
       is assumed that many other desktop applications are running.
       The  MySQL  server  is  configured to use minimal system
       resources.
     * Server Machine: Choose this option for a server machine where
       the  MySQL  server  is  running  alongside  other server
       applications such as FTP, email, and Web servers. The MySQL
       server is configured to use a moderate portion of the system
       resources.
     * Dedicated MySQL Server Machine: Choose this option for a
       server machine that is intended to run only the MySQL server.
       It is assumed that no other applications are running. The
       MySQL  server  is configured to use all available system
       resources.

Note

   By selecting one of the preconfigured configurations, the values
   and settings of various options in your my.cnf or my.ini will be
   altered accordingly. The default values and options as described
   in the reference manual may therefore be different to the options
   and  values  that  were  created during the execution of the
   configuration wizard.

2.4.8.4.5. The Database Usage Dialog

   The Database Usage dialog allows you to indicate the storage
   engines that you expect to use when creating MySQL tables. The
   option you choose determines whether the InnoDB storage engine is
   available  and  what  percentage of the server resources are
   available to InnoDB.
   MySQL Server Configuration Wizard: Usage Dialog
     * Multifunctional Database: This option enables both the InnoDB
       and  MyISAM storage engines and divides resources evenly
       between the two. This option is recommended for users who use
       both storage engines on a regular basis.
     * Transactional Database Only: This option enables both the
       InnoDB and MyISAM storage engines, but dedicates most server
       resources  to  the InnoDB storage engine. This option is
       recommended for users who use InnoDB almost exclusively and
       make only minimal use of MyISAM.
     * Non-Transactional Database Only: This option disables the
       InnoDB storage engine completely and dedicates all server
       resources  to  the MyISAM storage engine. This option is
       recommended for users who do not use InnoDB.

   The Configuration Wizard uses a template to generate the server
   configuration file. The Database Usage dialog sets one of the
   following option strings:
Multifunctional Database:        MIXED
Transactional Database Only:     INNODB
Non-Transactional Database Only: MYISAM

   When these options are processed through the default template
   (my-template.ini) the result is:
Multifunctional Database:
default-storage-engine=InnoDB
_myisam_pct=50

Transactional Database Only:
default-storage-engine=InnoDB
_myisam_pct=5

Non-Transactional Database Only:
default-storage-engine=MyISAM
_myisam_pct=100
skip-innodb

   The _myisam_pct value is used to calculate the percentage of
   resources  dedicated  to MyISAM. The remaining resources are
   allocated to InnoDB.

2.4.8.4.6. The InnoDB Tablespace Dialog

   Some users may want to locate the InnoDB tablespace files in a
   different location than the MySQL server data directory. Placing
   the tablespace files in a separate location can be desirable if
   your system has a higher capacity or higher performance storage
   device available, such as a RAID storage system.
   MySQL Server Configuration Wizard: InnoDB Data Tablespace

   To change the default location for the InnoDB tablespace files,
   choose a new drive from the drop-down list of drive letters and
   choose a new path from the drop-down list of paths. To create a
   custom path, click the ... button.

   If you are modifying the configuration of an existing server, you
   must click the Modify button before you change the path. In this
   situation you must move the existing tablespace files to the new
   location manually before starting the server.

2.4.8.4.7. The Concurrent Connections Dialog

   To  prevent  the server from running out of resources, it is
   important to limit the number of concurrent connections to the
   MySQL server that can be established. The Concurrent Connections
   dialog allows you to choose the expected usage of your server, and
   sets the limit for concurrent connections accordingly. It is also
   possible to set the concurrent connection limit manually.
   MySQL Server Configuration Wizard: Connections
     * Decision Support (DSS)/OLAP: Choose this option if your server
       does not require a large number of concurrent connections. The
       maximum number of connections is set at 100, with an average
       of 20 concurrent connections assumed.
     * Online Transaction Processing (OLTP): Choose this option if
       your server requires a large number of concurrent connections.
       The maximum number of connections is set at 500.
     * Manual Setting: Choose this option to set the maximum number
       of concurrent connections to the server manually. Choose the
       number  of concurrent connections from the drop-down box
       provided, or enter the maximum number of connections into the
       drop-down box if the number you desire is not listed.

2.4.8.4.8. The Networking and Strict Mode Options Dialog

   Use the Networking Options dialog to enable or disable TCP/IP
   networking  and to configure the port number that is used to
   connect to the MySQL server.
   MySQL Server Configuration Wizard: Network Configuration

   TCP/IP  networking  is enabled by default. To disable TCP/IP
   networking, uncheck the box next to the Enable TCP/IP Networking
   option.

   Port 3306 is used by default. To change the port used to access
   MySQL, choose a new port number from the drop-down box or type a
   new port number directly into the drop-down box. If the port
   number you choose is in use, you are prompted to confirm your
   choice of port number.

   Set the Server SQL Mode to either enable or disable strict mode.
   Enabling strict mode (default) makes MySQL behave more like other
   database management systems. If you run applications that rely on
   MySQL's old "forgiving" behavior, make sure to either adapt those
   applications or to disable strict mode. For more information about
   strict mode, see Section 5.1.7, "SQL Modes."

2.4.8.4.9. The Character Set Dialog

   The  MySQL server supports multiple character sets and it is
   possible to set a default server character set that is applied to
   all tables, columns, and databases unless overridden. Use the
   Character Set dialog to change the default character set of the
   MySQL server.
   MySQL Server Configuration Wizard: Character Set
     * Standard Character Set: Choose this option if you want to use
       latin1 as the default server character set. latin1 is used for
       English and many Western European languages.
     * Best Support For Multilingualism: Choose this option if you
       want to use utf8 as the default server character set. This is
       a Unicode character set that can store characters from many
       different languages.
     * Manual Selected Default Character Set / Collation: Choose this
       option if you want to pick the server's default character set
       manually. Choose the desired character set from the provided
       drop-down list.

2.4.8.4.10. The Service Options Dialog

   This section does not apply to MySQL Community Server users.

   On Windows platforms, the MySQL server can be installed as a
   Windows service. When installed this way, the MySQL server can be
   started automatically during system startup, and even restarted
   automatically by Windows in the event of a service failure.

   The MySQL Server Configuration Wizard installs the MySQL server as
   a service by default, using the service name MySQL. If you do not
   wish to install the service, uncheck the box next to the Install
   As Windows Service option. You can change the service name by
   picking a new service name from the drop-down box provided or by
   entering a new service name into the drop-down box.

Note

   Service names can include any legal character except forward (/)
   or backward (\) slashes, and must be less than 256 characters
   long.

Warning

   If you are installing multiple versions of MySQL onto the same
   machine, you must choose a different service name for each version
   that you install. If you do not choose a different service for
   each installed version then the service manager information will
   be  inconsitent and this will cause problems when you try to
   uninstall a previous version.

   If you have already installed multiple versions using the same
   service  name,  you  must  manually edit the contents of the
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servicesparameters
   within the Windows registry to update the association of the
   service name with the correct server version.

   Typically, when installing multiple versions you create a service
   name based on the version information. For example, you might
   install MySQL 5.x as mysql5, or specific versions such as MySQL
   5.0.56 as mysql5056.

   To install the MySQL server as a service but not have it started
   automatically at startup, uncheck the box next to the Launch the
   MySQL Server Automatically option.

2.4.8.4.11. The Security Options Dialog

   It is strongly recommended that you set a root password for your
   MySQL server, and the MySQL Server Configuration Wizard requires
   by  default that you do so. If you do not wish to set a root
   password, uncheck the box next to the Modify Security Settings
   option.
   MySQL Server Configuration Wizard: Security

   To set the root password, enter the desired password into both the
   New root password and Confirm boxes. If you are reconfiguring an
   existing server, you need to enter the existing root password into
   the Current root password box.

   To prevent root logins from across the network, check the box next
   to the Root may only connect from localhost option. This increases
   the security of your root account.

   To create an anonymous user account, check the box next to the
   Create An Anonymous Account option. Creating an anonymous account
   can  decrease server security and cause login and permission
   difficulties. For this reason, it is not recommended.

2.4.8.4.12. The Confirmation Dialog

   The final dialog in the MySQL Server Configuration Wizard is the
   Confirmation Dialog. To start the configuration process, click the
   Execute button. To return to a previous dialog, click the Back
   button. To exit the MySQL Server Configuration Wizard without
   configuring the server, click the Cancel button.
   MySQL Server Configuration Wizard: Confirmation

   After you click the Execute button, the MySQL Server Configuration
   Wizard  performs a series of tasks and displays the progress
   onscreen as the tasks are performed.

   The  MySQL  Server  Configuration  Wizard  first  determines
   configuration file options based on your choices using a template
   prepared by MySQL AB developers and engineers. This template is
   named my-template.ini and is located in your server installation
   directory.

   The MySQL Configuration Wizard then writes these options to the
   corresponding configuration file.

   If you chose to create a service for the MySQL server, the MySQL
   Server Configuration Wizard creates and starts the service. If you
   are  reconfiguring  an  existing  service,  the MySQL Server
   Configuration  Wizard  restarts  the  service  to apply your
   configuration changes.

   If you chose to set a root password, the MySQL Configuration
   Wizard connects to the server, sets your new root password, and
   applies any other security settings you may have selected.

   After the MySQL Server Configuration Wizard has completed its
   tasks, it displays a summary. Click the Finish button to exit the
   MySQL Server Configuration Wizard.

2.4.8.5. Installing MySQL from a Noinstall Zip Archive

   This section does not apply to MySQL Enterprise Server users.

   Users who are installing from the Noinstall package can use the
   instructions  in this section to manually install MySQL. The
   process for installing MySQL from a Zip archive is as follows:
    1. Extract the archive to the desired install directory
    2. Create an option file
    3. Choose a MySQL server type
    4. Start the MySQL server
    5. Secure the default user accounts

   This process is described in the sections that follow.

2.4.8.6. Extracting the Install Archive

   This section does not apply to MySQL Enterprise Server users.

   To install MySQL manually, do the following:
    1. If you are upgrading from a previous version please refer to
       Section  2.4.8.14,  "Upgrading MySQL on Windows," before
       beginning the upgrade process.
    2. Make sure that you are logged in as a user with administrator
       privileges.
    3. Choose an installation location. Traditionally, the MySQL
       server is installed in C:\mysql. The MySQL Installation Wizard
       installs MySQL under C:\Program Files\MySQL. If you do not
       install MySQL at C:\mysql, you must specify the path to the
       install directory during startup or in an option file. See
       Section 2.4.8.7, "Creating an Option File."
    4. Extract  the  install archive to the chosen installation
       location using your preferred Zip archive tool. Some tools may
       extract  the  archive  to  a  folder  within your chosen
       installation  location. If this occurs, you can move the
       contents  of  the subfolder into the chosen installation
       location.

2.4.8.7. Creating an Option File

   If you need to specify startup options when you run the server,
   you can indicate them on the command line or place them in an
   option file. For options that are used every time the server
   starts, you may find it most convenient to use an option file to
   specify your MySQL configuration. This is particularly true under
   the following circumstances:
     * The installation or data directory locations are different
       from the default locations (C:\Program Files\MySQL\MySQL
       Server 5.0 and C:\Program Files\MySQL\MySQL Server 5.0\data).
     * You need to tune the server settings.

   When the MySQL server starts on Windows, it looks for options in
   two files: the my.ini file in the Windows directory, and the
   C:\my.cnf file. The Windows directory typically is named something
   like C:\WINDOWS. You can determine its exact location from the
   value of the WINDIR environment variable using the following
   command:
C:\> echo %WINDIR%

   MySQL looks for options first in the my.ini file, and then in the
   my.cnf file. However, to avoid confusion, it's best if you use
   only one file. If your PC uses a boot loader where C: is not the
   boot drive, your only option is to use the my.ini file. Whichever
   option file you use, it must be a plain text file.

   You can also make use of the example option files included with
   your MySQL distribution; see Section 4.2.3.2.2, "Preconfigured
   Option Files."

   An option file can be created and modified with any text editor,
   such as Notepad. For example, if MySQL is installed in E:\mysql
   and the data directory is in E:\mydata\data, you can create an
   option file containing a [mysqld] section to specify values for
   the basedir and datadir parameters:
[mysqld]
# set basedir to your installation path
basedir=E:/mysql
# set datadir to the location of your data directory
datadir=E:/mydata/data

   Note that Windows pathnames are specified in option files using
   (forward)  slashes  rather  than  backslashes. If you do use
   backslashes, you must double them:
[mysqld]
# set basedir to your installation path
basedir=E:\\mysql
# set datadir to the location of your data directory
datadir=E:\\mydata\\data

   On Windows, the MySQL installer places the data directory directly
   under the directory where you install MySQL. If you would like to
   use a data directory in a different location, you should copy the
   entire contents of the data directory to the new location. For
   example, if MySQL is installed in C:\Program Files\MySQL\MySQL
   Server  5.0,  the data directory is by default in C:\Program
   Files\MySQL\MySQL Server 5.0\data. If you want to use E:\mydata as
   the data directory instead, you must do two things:
    1. Move the entire data directory and all of its contents from
       C:\Program Files\MySQL\MySQL Server 5.0\data to E:\mydata.
    2. Use a --datadir option to specify the new data directory
       location each time you start the server.

2.4.8.8. Selecting a MySQL Server Type

   This section does not apply to MySQL Enterprise Server users.

   The following table shows the available servers for Windows in
   MySQL 5.0.
   Binary Description
   mysqld-nt Optimized binary with named-pipe support
   mysqld Optimized binary without named-pipe support
   mysqld-debug Like mysqld-nt, but compiled with full debugging and
   automatic memory allocation checking

   All of the preceding binaries are optimized for modern Intel
   processors, but should work on any Intel i386-class or higher
   processor.

   Each of the servers in a distribution support the same set of
   storage engines. The SHOW ENGINES statement displays which engines
   a given server supports.

   All Windows MySQL 5.0 servers have support for symbolic linking of
   database directories.

   MySQL supports TCP/IP on all Windows platforms. MySQL servers on
   Windows support named pipes as indicated in the following list.
   However, the default is to use TCP/IP regardless of platform.
   (Named   pipes  are  slower  than  TCP/IP  in  many  Windows
   configurations.)

   Use of named pipes is subject to these conditions:
     * Named pipes are enabled only if you start the server with the
       --enable-named-pipe option. It is necessary to use this option
       explicitly because some users have experienced problems with
       shutting down the MySQL server when named pipes were used.
     * Named-pipe connections are allowed only by the mysqld-nt and
       mysqld-debug servers.

Note

   Most of the examples in this manual use mysqld as the server name.
   If you choose to use a different server, such as mysqld-nt, make
   the appropriate substitutions in the commands that are shown in
   the examples.

2.4.8.9. Starting the Server for the First Time

   This  section gives a general overview of starting the MySQL
   server. The following sections provide more specific information
   for  starting the MySQL server from the command line or as a
   Windows service.

   The information here applies primarily if you installed MySQL
   using the Noinstall version, or if you wish to configure and test
   MySQL manually rather than with the GUI tools.

   The examples in these sections assume that MySQL is installed
   under the default location of C:\Program Files\MySQL\MySQL Server
   5.0. Adjust the pathnames shown in the examples if you have MySQL
   installed in a different location.

   Clients have two options. They can use TCP/IP, or they can use a
   named pipe if the server supports named-pipe connections.

   MySQL for Windows also supports shared-memory connections if the
   server is started with the --shared-memory option. Clients can
   connect through shared memory by using the --protocol=MEMORY
   option.

   For information about which server binary to run, see Section
   2.4.8.8, "Selecting a MySQL Server Type."

   Testing is best done from a command prompt in a console window (or
   "DOS window"). In this way you can have the server display status
   messages in the window where they are easy to see. If something is
   wrong with your configuration, these messages make it easier for
   you to identify and fix any problems.

   To start the server, enter this command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld" --console

   For a server that includes InnoDB support, you should see the
   messages similar to those following as it starts (the pathnames
   and sizes may differ):
InnoDB: The first specified datafile c:\ibdata\ibdata1 did not exist:
InnoDB: a new database to be created!
InnoDB: Setting file c:\ibdata\ibdata1 size to 209715200
InnoDB: Database physically writes the file full: wait...
InnoDB: Log file c:\iblogs\ib_logfile0 did not exist: new to be creat
ed
InnoDB: Setting log file c:\iblogs\ib_logfile0 size to 31457280
InnoDB: Log file c:\iblogs\ib_logfile1 did not exist: new to be creat
ed
InnoDB: Setting log file c:\iblogs\ib_logfile1 size to 31457280
InnoDB: Log file c:\iblogs\ib_logfile2 did not exist: new to be creat
ed
InnoDB: Setting log file c:\iblogs\ib_logfile2 size to 31457280
InnoDB: Doublewrite buffer not found: creating new
InnoDB: Doublewrite buffer created
InnoDB: creating foreign key constraint system tables
InnoDB: foreign key constraint system tables created
011024 10:58:25  InnoDB: Started

   When the server finishes its startup sequence, you should see
   something like this, which indicates that the server is ready to
   service client connections:
mysqld: ready for connections
Version: '5.0.68'  socket: ''  port: 3306

   The  server  continues  to  write to the console any further
   diagnostic output it produces. You can open a new console window
   in which to run client programs.

   If you omit the --console option, the server writes diagnostic
   output  to  the  error log in the data directory (C:\Program
   Files\MySQL\MySQL Server 5.0\data by default). The error log is
   the file with the .err extension.

Note

   The accounts that are listed in the MySQL grant tables initially
   have no passwords. After starting the server, you should set up
   passwords for them using the instructions in Section 2.4.16,
   "Post-Installation Setup and Testing."

2.4.8.10. Starting MySQL from the Windows Command Line

   The MySQL server can be started manually from the command line.
   This can be done on any version of Windows.

   To start the mysqld server from the command line, you should start
   a console window (or "DOS window") and enter this command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld"

   The path to mysqld may vary depending on the install location of
   MySQL on your system.

   You can stop the MySQL server by executing this command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqladmin" -u root
 shutdown

Note

   If the MySQL root user account has a password, you need to invoke
   mysqladmin  with  the -p option and supply the password when
   prompted.

   This command invokes the MySQL administrative utility mysqladmin
   to connect to the server and tell it to shut down. The command
   connects  as  the  MySQL  root  user,  which  is the default
   administrative account in the MySQL grant system. Note that users
   in the MySQL grant system are wholly independent from any login
   users under Windows.

   If mysqld doesn't start, check the error log to see whether the
   server wrote any messages there to indicate the cause of the
   problem.   The  error  log  is  located  in  the  C:\Program
   Files\MySQL\MySQL Server 5.0\data directory. It is the file with a
   suffix of .err. You can also try to start the server as mysqld
   --console; in this case, you may get some useful information on
   the screen that may help solve the problem.

   The last option is to start mysqld with the --standalone and
   --debug  options.  In  this  case,  mysqld writes a log file
   C:\mysqld.trace that should contain the reason why mysqld doesn't
   start. See MySQL Internals: Porting
   (http://forge.mysql.com/wiki/MySQL_Internals_Porting).

   Use mysqld --verbose --help to display all the options that mysqld
   understands.

2.4.8.11. Starting MySQL as a Windows Service

   On Windows, the recommended way to run MySQL is to install it as a
   Windows service, whereby MySQL starts and stops automatically when
   Windows starts and stops. A MySQL server installed as a service
   can also be controlled from the command line using NET commands,
   or with the graphical Services utility. Generally, to install
   MySQL  as a Windows service you should be logged in using an
   account that has administrator rights.

   The Services utility (the Windows Service Control Manager) can be
   found in the Windows Control Panel (under Administrative Tools on
   Windows 2000, XP, Vista, and Server 2003). To avoid conflicts, it
   is advisable to close the Services utility while performing server
   installation or removal operations from the command line.

   Before installing MySQL as a Windows service, you should first
   stop the current server if it is running by using the following
   command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqladmin"
          -u root shutdown

Note

   If the MySQL root user account has a password, you need to invoke
   mysqladmin  with  the -p option and supply the password when
   prompted.

   This command invokes the MySQL administrative utility mysqladmin
   to connect to the server and tell it to shut down. The command
   connects  as  the  MySQL  root  user,  which  is the default
   administrative account in the MySQL grant system. Note that users
   in the MySQL grant system are wholly independent from any login
   users under Windows.

   Install the server as a service using this command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld" --install

   The  service-installation command does not start the server.
   Instructions for that are given later in this section.

   To  make it easier to invoke MySQL programs, you can add the
   pathname of the MySQL bin directory to your Windows system PATH
   environment variable:
     * On the Windows desktop, right-click on the My Computer icon,
       and select Properties
     * Next select the Advanced tab from the System Properties menu
       that appears, and click the Environment Variables button.
     * Under System Variables, select Path, and then click the Edit
       button. The Edit System Variable dialogue should appear.
     * Place your cursor at the end of the text appearing in the
       space marked Variable Value. (Use the End key to ensure that
       your cursor is positioned at the very end of the text in this
       space.) Then enter the complete pathname of your MySQL bin
       directory (for example, C:\Program Files\MySQL\MySQL Server
       5.0\bin), Note that there should be a semicolon separating
       this path from any values present in this field. Dismiss this
       dialogue, and each dialogue in turn, by clicking OK until all
       of the dialogues that were opened have been dismissed. You
       should now be able to invoke any MySQL executable program by
       typing its name at the DOS prompt from any directory on the
       system, without having to supply the path. This includes the
       servers,  the  mysql  client, and all MySQL command-line
       utilities such as mysqladmin and mysqldump.
       You should not add the MySQL bin directory to your Windows
       PATH if you are running multiple MySQL servers on the same
       machine.

Warning

   You must exercise great care when editing your system PATH by
   hand; accidental deletion or modification of any portion of the
   existing PATH value can leave you with a malfunctioning or even
   unusable system.

   The following additional arguments can be used in MySQL 5.0 when
   installing the service:
     * You can specify a service name immediately following the
       --install option. The default service name is MySQL.
     * If a service name is given, it can be followed by a single
       option.     By     convention,     this     should    be
       --defaults-file=file_name to specify the name of an option
       file from which the server should read options when it starts.
       The use of a single option other than --defaults-file is
       possible but discouraged. --defaults-file is more flexible
       because it enables you to specify multiple startup options for
       the server by placing them in the named option file. Also, in
       MySQL 5.0, use of an option different from --defaults-file is
       not supported until 5.0.3.
     * As of MySQL 5.0.1, you can also specify a --local-service
       option following the service name. This causes the server to
       run using the LocalService Windows account that has limited
       system privileges. This account is available only for Windows
       XP or newer. If both --defaults-file and --local-service are
       given following the service name, they can be in any order.

   For a MySQL server that is installed as a Windows service, the
   following rules determine the service name and option files that
   the server uses:
     * If the service-installation command specifies no service name
       or the default service name (MySQL) following the --install
       option, the server uses the a service name of MySQL and reads
       options from the [mysqld] group in the standard option files.
     * If the service-installation command specifies a service name
       other than MySQL following the --install option, the server
       uses that service name. It reads options from the [mysqld]
       group and the group that has the same name as the service in
       the standard option files. This allows you to use the [mysqld]
       group for options that should be used by all MySQL services,
       and an option group with the service name for use by the
       server installed with that service name.
     * If   the   service-installation   command   specifies  a
       --defaults-file option after the service name, the server
       reads options only from the [mysqld] group of the named file
       and ignores the standard option files.

   As a more complex example, consider the following command:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld"
          --install MySQL --defaults-file=C:\my-opts.cnf

   Here,  the  default  service name (MySQL) is given after the
   --install option. If no --defaults-file option had been given,
   this command would have the effect of causing the server to read
   the  [mysqld] group from the standard option files. However,
   because the --defaults-file option is present, the server reads
   options from the [mysqld] option group, and only from the named
   file.

   You can also specify options as Start parameters in the Windows
   Services utility before you start the MySQL service.

   Once a MySQL server has been installed as a service, Windows
   starts the service automatically whenever Windows starts. The
   service also can be started immediately from the Services utility,
   or by using a NET START MySQL command. The NET command is not case
   sensitive.

   When run as a service, mysqld has no access to a console window,
   so no messages can be seen there. If mysqld does not start, check
   the error log to see whether the server wrote any messages there
   to indicate the cause of the problem. The error log is located in
   the   MySQL   data   directory   (for   example,  C:\Program
   Files\MySQL\MySQL Server 5.0\data). It is the file with a suffix
   of .err.

   When a MySQL server has been installed as a service, and the
   service is running, Windows stops the service automatically when
   Windows shuts down. The server also can be stopped manually by
   using the Services utility, the NET STOP MySQL command, or the
   mysqladmin shutdown command.

   You also have the choice of installing the server as a manual
   service  if  you  do  not wish for the service to be started
   automatically  during  the boot process. To do this, use the
   --install-manual option rather than the --install option:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld" --install-m
anual

   To remove a server that is installed as a service, first stop it
   if  it  is running by executing NET STOP MySQL. Then use the
   --remove option to remove it:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld" --remove

   If mysqld is not running as a service, you can start it from the
   command line. For instructions, see Section 2.4.8.10, "Starting
   MySQL from the Windows Command Line."

   Please see Section 2.4.8.13, "Troubleshooting a MySQL Installation
   Under Windows," if you encounter difficulties during installation.

2.4.8.12. Testing The MySQL Installation

   You can test whether the MySQL server is working by executing any
   of the following commands:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqlshow"
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqlshow" -u root
mysql
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqladmin" version
 status proc
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysql" test

   If mysqld is slow to respond to TCP/IP connections from client
   programs, there is probably a problem with your DNS. In this case,
   start mysqld with the --skip-name-resolve option and use only
   localhost and IP numbers in the Host column of the MySQL grant
   tables.

   You can force a MySQL client to use a named-pipe connection rather
   than TCP/IP by specifying the --pipe or --protocol=PIPE option, or
   by specifying . (period) as the host name. Use the --socket option
   to specify the name of the pipe if you do not want to use the
   default pipe name.

   Note that if you have set a password for the root account, deleted
   the anonymous account, or created a new user account, then you
   must use the appropriate -u and -p options with the commands shown
   above in order to connect with the MySQL Server. See Section
   4.2.2, "Connecting to the MySQL Server."

   For  more  information  about  mysqlshow, see Section 4.5.6,
   "mysqlshow --- Display Database, Table, and Column Information."

2.4.8.13. Troubleshooting a MySQL Installation Under Windows

   When installing and running MySQL for the first time, you may
   encounter  certain errors that prevent the MySQL server from
   starting. The purpose of this section is to help you diagnose and
   correct some of these errors.

   Your first resource when troubleshooting server issues is the
   error  log.  The  MySQL  server uses the error log to record
   information relevant to the error that prevents the server from
   starting. The error log is located in the data directory specified
   in  your my.ini file. The default data directory location is
   C:\Program Files\MySQL\MySQL Server 5.0\data. See Section 5.2.1,
   "The Error Log."

   Another source of information regarding possible errors is the
   console messages displayed when the MySQL service is starting. Use
   the NET START MySQL command from the command line after installing
   mysqld  as a service to see any error messages regarding the
   starting of the MySQL server as a service. See Section 2.4.8.11,
   "Starting MySQL as a Windows Service."

   The following examples show other common error messages you may
   encounter when installing MySQL and starting the server for the
   first time:
     * If the MySQL server cannot find the mysql privileges database
       or other critical files, you may see these messages:
System error 1067 has occurred.
Fatal error: Can't open privilege tables: Table 'mysql.host' doesn't
exist
       These  messages  often occur when the MySQL base or data
       directories are installed in different locations than the
       default locations (C:\Program Files\MySQL\MySQL Server 5.0 and
       C:\Program Files\MySQL\MySQL Server 5.0\data, respectively).
       This situation may occur when MySQL is upgraded and installed
       to a new location, but the configuration file is not updated
       to reflect the new location. In addition, there may be old and
       new configuration files that conflict. Be sure to delete or
       rename any old configuration files when upgrading MySQL.
       If  you  have  installed MySQL to a directory other than
       C:\Program Files\MySQL\MySQL Server 5.0, you need to ensure
       that the MySQL server is aware of this through the use of a
       configuration (my.ini) file. The my.ini file needs to be
       located in your Windows directory, typically C:\WINDOWS. You
       can determine its exact location from the value of the WINDIR
       environment variable by issuing the following command from the
       command prompt:
C:\> echo %WINDIR%
       An option file can be created and modified with any text
       editor, such as Notepad. For example, if MySQL is installed in
       E:\mysql and the data directory is D:\MySQLdata, you can
       create  the option file and set up a [mysqld] section to
       specify values for the basedir and datadir parameters:
[mysqld]
# set basedir to your installation path
basedir=E:/mysql
# set datadir to the location of your data directory
datadir=D:/MySQLdata
       Note that Windows pathnames are specified in option files
       using (forward) slashes rather than backslashes. If you do use
       backslashes, you must double them:
[mysqld]
# set basedir to your installation path
basedir=C:\\Program Files\\MySQL\\MySQL Server 5.0
# set datadir to the location of your data directory
datadir=D:\\MySQLdata
       MySQL Enterprise For expert advice on the start-up options
       appropriate to your circumstances, subscribe to the MySQL
       Enterprise    Monitor.   For   more   information,   see
       http://www.mysql.com/products/enterprise/advisors.html.
       If you change the datadir value in your MySQL configuration
       file, you must move the contents of the existing MySQL data
       directory before restarting the MySQL server.
       See Section 2.4.8.7, "Creating an Option File."
     * If you reinstall or upgrade MySQL without first stopping and
       removing the existing MySQL service and install MySQL using
       the MySQL Configuration Wizard, you may see this error:
Error: Cannot create Windows service for MySql. Error: 0
       This occurs when the Configuration Wizard tries to install the
       service and finds an existing service with the same name.
       One solution to this problem is to choose a service name other
       than mysql when using the configuration wizard. This allows
       the new service to be installed correctly, but leaves the
       outdated service in place. Although this is harmless, it is
       best to remove old services that are no longer in use.
       To permanently remove the old mysql service, execute the
       following command as a user with administrative privileges, on
       the command-line:
C:\> sc delete mysql
[SC] DeleteService SUCCESS
       If  the  sc utility is not available for your version of
       Windows,    download    the    delsrv    utility    from
       http://www.microsoft.com/windows2000/techinfo/reskit/tools/exi
       sting/delsrv-o.asp and use the delsrv mysql syntax.

2.4.8.14. Upgrading MySQL on Windows

   This section does not apply to MySQL Enterprise Server users.

   This  section  lists  some of the steps you should take when
   upgrading MySQL on Windows.
    1. Review Section 2.4.17, "Upgrading MySQL," for additional
       information  on  upgrading MySQL that is not specific to
       Windows.
    2. You should always back up your current MySQL installation
       before performing an upgrade. See Section 6.1, "Database
       Backups."
    3. Download  the  latest Windows distribution of MySQL from
       http://dev.mysql.com/downloads/.
    4. Before upgrading MySQL, you must stop the server. If the
       server is installed as a service, stop the service with the
       following command from the command prompt:
C:\> NET STOP MySQL
       If you are not running the MySQL server as a service, use the
       following command to stop it:
C:\> "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqladmin" -u root
 shutdown

Note
       If the MySQL root user account has a password, you need to
       invoke mysqladmin with the -p option and supply the password
       when prompted.
    5. When upgrading to MySQL 5.0 from a version previous to 4.1.5,
       or when upgrading from a version of MySQL installed from a Zip
       archive  to  a version of MySQL installed with the MySQL
       Installation Wizard, you must manually remove the previous
       installation and MySQL service (if the server is installed as
       a service).
       To remove the MySQL service, use the following command:
C:\> C:\mysql\bin\mysqld --remove
       If  you  do  not  remove the existing service, the MySQL
       Installation Wizard may fail to properly install the new MySQL
       service.
    6. If you are using the MySQL Installation Wizard, start the
       wizard as described in Section 2.4.8.3, "Using the MySQL
       Installation Wizard."
    7. If you are installing MySQL from a Zip archive, extract the
       archive.  You  may  either overwrite your existing MySQL
       installation (usually located at C:\mysql), or install it into
       a different directory, such as C:\mysql5. Overwriting the
       existing installation is recommended.
    8. If you were running MySQL as a Windows service and you had to
       remove the service earlier in this procedure, reinstall the
       service. (See Section 2.4.8.11, "Starting MySQL as a Windows
       Service.")
    9. Restart the server. For example, use NET START MySQL if you
       run MySQL as a service, or invoke mysqld directly otherwise.
   10. If   you   encounter   errors,   see  Section  2.4.8.13,
       "Troubleshooting a MySQL Installation Under Windows."

2.4.8.15. MySQL on Windows Compared to MySQL on Unix

   MySQL for Windows has proven itself to be very stable. The Windows
   version of MySQL has the same features as the corresponding Unix
   version, with the following exceptions:
     * Limited number of ports
       Windows systems have about 4,000 ports available for client
       connections, and after a connection on a port closes, it takes
       two  to  four  minutes before the port can be reused. In
       situations where clients connect to and disconnect from the
       server at a high rate, it is possible for all available ports
       to be used up before closed ports become available again. If
       this happens, the MySQL server appears to be unresponsive even
       though it is running. Note that ports may be used by other
       applications running on the machine as well, in which case the
       number of ports available to MySQL is lower.
       For   more   information   about   this   problem,   see
       http://support.microsoft.com/default.aspx?scid=kb;en-us;196271
       .
     * Concurrent reads
       MySQL depends on the pread() and pwrite() system calls to be
       able to mix INSERT and SELECT. Currently, we use mutexes to
       emulate pread() and pwrite(). We intend to replace the file
       level interface with a virtual interface in the future so that
       we can use the readfile()/writefile() interface to get more
       speed. The current implementation limits the number of open
       files that MySQL 5.0 can use to 2,048, which means that you
       cannot run as many concurrent threads on Windows as on Unix.
     * Blocking read
       MySQL uses a blocking read for each connection. That has the
       following implications if named-pipe connections are enabled:
          + A connection is not disconnected automatically after
            eight hours, as happens with the Unix version of MySQL.
          + If a connection hangs, it is not possible to break it
            without killing MySQL.
          + mysqladmin kill does not work on a sleeping connection.
          + mysqladmin shutdown cannot abort as long as there are
            sleeping connections.
       We plan to fix this problem in the future.
     * ALTER TABLE
       While you are executing an ALTER TABLE statement, the table is
       locked from being used by other threads. This has to do with
       the fact that on Windows, you can't delete a file that is in
       use by another thread. In the future, we may find some way to
       work around this problem.
     * DROP TABLE
       DROP TABLE on a table that is in use by a MERGE table does not
       work on Windows because the MERGE handler does the table
       mapping hidden from the upper layer of MySQL. Because Windows
       does not allow dropping files that are open, you first must
       flush all MERGE tables (with FLUSH TABLES) or drop the MERGE
       table before dropping the table.
     * DATA DIRECTORY and INDEX DIRECTORY
       The DATA DIRECTORY and INDEX DIRECTORY options for CREATE
       TABLE are ignored on Windows, because Windows doesn't support
       symbolic links. These options also are ignored on systems that
       have a non-functional realpath() call.
     * DROP DATABASE
       You cannot drop a database that is in use by some thread.
     * Case-insensitive names
       Filenames are not case sensitive on Windows, so MySQL database
       and table names are also not case sensitive on Windows. The
       only restriction is that database and table names must be
       specified using the same case throughout a given statement.
       See Section 8.2.2, "Identifier Case Sensitivity."
     * The "\" pathname separator character
       Pathname  components in Windows are separated by the "\"
       character, which is also the escape character in MySQL. If you
       are using LOAD DATA INFILE or SELECT ... INTO OUTFILE, use
       Unix-style filenames with "/" characters:
mysql> LOAD DATA INFILE 'C:/tmp/skr.txt' INTO TABLE skr;
mysql> SELECT * INTO OUTFILE 'C:/tmp/skr.txt' FROM skr;
       Alternatively, you must double the "\" character:
mysql> LOAD DATA INFILE 'C:\\tmp\\skr.txt' INTO TABLE skr;
mysql> SELECT * INTO OUTFILE 'C:\\tmp\\skr.txt' FROM skr;
     * Problems with pipes
       Pipes do not work reliably from the Windows command-line
       prompt. If the pipe includes the character ^Z / CHAR(24),
       Windows thinks that it has encountered end-of-file and aborts
       the program.
       This is mainly a problem when you try to apply a binary log as
       follows:
C:\> mysqlbinlog binary_log_file | mysql --user=root
       If you have a problem applying the log and suspect that it is
       because  of  a  ^Z / CHAR(24) character, you can use the
       following workaround:
C:\> mysqlbinlog binary_log_file --result-file=/tmp/bin.sql
C:\> mysql --user=root --execute "source /tmp/bin.sql"
       The latter command also can be used to reliably read in any
       SQL file that may contain binary data.
     * Access denied for user error
       If MySQL cannot resolve your hostname properly, you may get
       the following error when you attempt to run a MySQL client
       program to connect to a server running on the same machine:
Access denied for user 'some_user'@'unknown'
to database 'mysql'
       To  fix  this  problem,  you  should create a file named
       \windows\hosts containing the following information:
127.0.0.1       localhost

   Here are some open issues for anyone who might want to help us
   improve MySQL on Windows:
     * Add macros to use the faster thread-safe increment/decrement
       methods provided by Windows.

2.4.9. Installing MySQL from RPM Packages on Linux

   The  recommended  way  to  install  MySQL on RPM-based Linux
   distributions is by using the RPM packages. The RPMs provided by
   MySQL AB to the community should work on all versions of Linux
   that  support  RPM packages and use glibc 2.3. MySQL AB also
   provides  RPMs with binaries that are statically linked to a
   patched  version of glibc 2.2, but only for the x86 (32-bit)
   architecture. To obtain RPM packages, see Section 2.4.4, "How to
   Get MySQL."

   For non-RPM Linux distributions, you can install MySQL using a
   .tar.gz package. See Section 2.4.14, "Installing MySQL from tar.gz
   Packages on Other Unix-Like Systems."

   MySQL AB does provide some platform-specific RPMs; the difference
   between  a platform-specific RPM and a generic RPM is that a
   platform-specific RPM is built on the targeted platform and is
   linked dynamically whereas a generic RPM is linked statically with
   LinuxThreads.

Note

   RPM distributions of MySQL often are provided by other vendors. Be
   aware that they may differ in features and capabilities from those
   built by MySQL AB, and that the instructions in this manual do not
   necessarily apply to installing them. The vendor's instructions
   should be consulted instead.

   If you have problems with an RPM file (for example, if you receive
   the error Sorry, the host 'xxxx' could not be looked up), see
   Section 2.4.19.1.2, "Linux Binary Distribution Notes."

   In most cases, you need to install only the MySQL-server and
   MySQL-client packages to get a functional MySQL installation. The
   other packages are not required for a standard installation.

   For upgrades, if your installation was originally produced by
   installing multiple RPM packages, it is best to upgrade all the
   packages, not just some. For example, if you previously installed
   the server and client RPMs, do not upgrade just the server RPM.

   If you get a dependency failure when trying to install MySQL
   packages (for example, error: removing these packages would break
   dependencies: libmysqlclient.so.10 is needed by ...), you should
   also install the MySQL-shared-compat package, which includes both
   the    shared    libraries    for   backward   compatibility
   (libmysqlclient.so.12 for MySQL 4.0 and libmysqlclient.so.10 for
   MySQL 3.23).

   Some Linux distributions still ship with MySQL 3.23 and they
   usually link applications dynamically to save disk space. If these
   shared  libraries  are  in  a separate package (for example,
   MySQL-shared), it is sufficient to simply leave this package
   installed and just upgrade the MySQL server and client packages
   (which are statically linked and do not depend on the shared
   libraries). For distributions that include the shared libraries in
   the same package as the MySQL server (for example, Red Hat Linux),
   you could either install our 3.23 MySQL-shared RPM, or use the
   MySQL-shared-compat package instead. (Do not install both.)

   The RPM packages shown in the following list are available. The
   names shown here use a suffix of .glibc23.i386.rpm, but particular
   packages can have different suffixes, as described later. Packages
   that have community in the names are Community Server builds,
   available from MySQL 5.0.27 on.
     * MySQL-server-VERSION.glibc23.i386.rpm,
       MySQL-server-community-VERSION.glibc23.i386.rpm
       The  MySQL server. You need this unless you only want to
       connect to a MySQL server running on another machine.
     * MySQL-client-VERSION.glibc23.i386.rpm,
       MySQL-client-community-VERSION.glibc23.i386.rpm
       The standard MySQL client programs. You probably always want
       to install this package.
     * MySQL-bench-VERSION.glibc23.i386.rpm
       Tests and benchmarks. Requires Perl and the DBI and DBD::mysql
       modules.
     * MySQL-devel-VERSION.glibc23.i386.rpm,
       MySQL-devel-community-VERSION.glibc23.i386.rpm
       The libraries and include files that are needed if you want to
       compile other MySQL clients, such as the Perl modules.
     * MySQL-debuginfo-VERSION.glibc23.i386.rpm,
       MySQL-community-debuginfo-VERSION.glibc23.i386.rpm
       This package contains debugging information. debuginfo RPMs
       are never needed to use MySQL software; this is true both for
       the server and for client programs. However, they contain
       additional information that might be needed by a debugger to
       analyze a crash.
     * MySQL-shared-VERSION.glibc23.i386.rpm,
       MySQL-shared-community-VERSION.glibc23.i386.rpm
       This    package    contains    the    shared   libraries
       (libmysqlclient.so*) that certain languages and applications
       need  to  dynamically  load  and  use MySQL. It contains
       single-threaded and thread-safe libraries. If you install this
       package, do not install the MySQL-shared-compat package.
     * MySQL-shared-compat-VERSION.glibc23.i386.rpm
       This package includes the shared libraries for MySQL 3.23,
       4.0, 4.1, and 5.0. It contains single-threaded and thread-safe
       libraries. Install this package instead of MySQL-shared if you
       have  applications installed that are dynamically linked
       against older versions of MySQL but you want to upgrade to the
       current version without breaking the library dependencies.
     * MySQL-clustermanagement-communityVERSION.glibc23.i386.rpm,
       MySQL-clusterstorage-communityVERSION.glibc23.i386.rpm,
       MySQL-clustertools-communityVERSION.glibc23.i386.rpm,
       MySQL-clusterextra-communityVERSION.glibc23.i386.rpm
       Packages that contain additional files for MySQL Cluster
       installations. These are platform-specific RPMs, in contrast
       to the platform-independent ndb-xxx RPMs.

Note
       The MySQL-clustertools RPM requires a working installation of
       perl and the DBI and HTML::Template packages. See Section
       2.4.21, "Perl Installation Notes," and Section 19.10.14,
       "ndb_size.pl --- NDBCLUSTER Size Requirement Estimator," for
       more information.
     * MySQL-ndb-management-VERSION.glibc23.i386.rpm,
       MySQL-ndb-storage-VERSION.glibc23.i386.rpm,
       MySQL-ndb-tools-VERSION.glibc23.i386.rpm,
       MySQL-ndb-extra-VERSION.glibc23.i386.rpm
       Packages that contain additional files for MySQL Cluster
       installations.  These  are platform-independent RPMs, in
       contrast to the platform-specific clusterxxx-community RPMs.
     * MySQL-test-community-VERSION.glibc23.i386.rpm
       This package includes the MySQL test suite.
     * MySQL-VERSION.src.rpm
       This  contains  the  source code for all of the previous
       packages. It can also be used to rebuild the RPMs on other
       architectures (for example, Alpha or SPARC).

   The suffix of RPM package names (following the VERSION value) has
   the following syntax:
[.PLATFORM].CPU.rpm

   The PLATFORM and CPU values indicate the type of system for which
   the  package  is  built. PLATFORM, if present, indicates the
   platform, and CPU indicates the processor type or family.

   If   the   PLATFORM   value   is   missing   (for   example,
   MySQL-server-VERSION.i386.rpm), the package is statically linked
   against a version of glibc 2.2 that has been patched to handle
   larger numbers of threads with larger stack sizes than the stock
   library.

   If PLATFORM is present, the package is dynamically linked against
   glibc 2.3 and the PLATFORM value indicates whether the package is
   platform independent or intended for a specific platform:
   glibc23 Platform independent, should run on any Linux distribution
   that supports glibc 2.3
   rhel3, rhel4 Red Hat Enterprise Linux 3 or 4
   sles9, sles10 SuSE Linux Enterprise Server 9 or 10

   The CPU value indicates the processor type or family for which the
   package is built:
   i386   x86 processor, 386 and up
   i586   x86 processor, Pentium and up
   x86_64 64-bit x86 processor
   ia64   Itanium (IA-64) processor

   To see all files in an RPM package (for example, a MySQL-server
   RPM), run a command like this:
shell> rpm -qpl MySQL-server-VERSION.glibc23.i386.rpm

   To perform a standard minimal installation, install the server and
   client RPMs:
shell> rpm -i MySQL-server-VERSION.glibc23.i386.rpm
shell> rpm -i MySQL-client-VERSION.glibc23.i386.rpm

   To install only the client programs, install just the client RPM:
shell> rpm -i MySQL-client-VERSION.glibc23.i386.rpm

   RPM provides a feature to verify the integrity and authenticity of
   packages before installing them. If you would like to learn more
   about  this  feature,  see Section 2.4.5, "Verifying Package
   Integrity Using MD5 Checksums or GnuPG."

   The server RPM places data under the /var/lib/mysql directory. The
   RPM also creates a login account for a user named mysql (if one
   does not exist) to use for running the MySQL server, and creates
   the  appropriate entries in /etc/init.d/ to start the server
   automatically at boot time. (This means that if you have performed
   a previous installation and have made changes to its startup
   script, you may want to make a copy of the script so that you
   don't  lose  it  when  you install a newer RPM.) See Section
   2.4.16.2.2, "Starting and Stopping MySQL Automatically," for more
   information on how MySQL can be started automatically on system
   startup.

   If you want to install the MySQL RPM on older Linux distributions
   that  do  not  support initialization scripts in /etc/init.d
   (directly or via a symlink), you should create a symbolic link
   that points to the location where your initialization scripts
   actually  are  installed.  For  example, if that location is
   /etc/rc.d/init.d, use these commands before installing the RPM to
   create /etc/init.d as a symbolic link that points there:
shell> cd /etc
shell> ln -s rc.d/init.d .

   However, all current major Linux distributions should support the
   new directory layout that uses /etc/init.d, because it is required
   for LSB (Linux Standard Base) compliance.

   If the RPM files that you install include MySQL-server, the mysqld
   server should be up and running after installation. You should be
   able to start using MySQL.

   If something goes wrong, you can find more information in the
   binary installation section. See Section 2.4.14, "Installing MySQL
   from tar.gz Packages on Other Unix-Like Systems."

Note

   The accounts that are listed in the MySQL grant tables initially
   have no passwords. After starting the server, you should set up
   passwords for them using the instructions in Section 2.4.16,
   "Post-Installation Setup and Testing."

2.4.10. Installing MySQL on Mac OS X

   You can install MySQL on Mac OS X 10.3.x ("Panther") or newer
   using a Mac OS X binary package in PKG format instead of the
   binary tarball distribution. Please note that older versions of
   Mac OS X (for example, 10.1.x or 10.2.x) are not supported by this
   package.

   The package is located inside a disk image (.dmg) file that you
   first need to mount by double-clicking its icon in the Finder. It
   should then mount the image and display its contents.

   To obtain MySQL, see Section 2.4.4, "How to Get MySQL."

Note

   Before proceeding with the installation, be sure to shut down all
   running MySQL server instances by either using the MySQL Manager
   Application (on Mac OS X Server) or via mysqladmin shutdown on the
   command line.

   To  actually install the MySQL PKG file, double-click on the
   package icon. This launches the Mac OS X Package Installer, which
   guides you through the installation of MySQL.

   Due to a bug in the Mac OS X package installer, you may see this
   error message in the destination disk selection dialog:
You cannot install this software on this disk. (null)

   If this error occurs, simply click the Go Back button once to
   return to the previous screen. Then click Continue to advance to
   the destination disk selection again, and you should be able to
   choose the destination disk correctly. We have reported this bug
   to Apple and it is investigating this problem.

   The   Mac   OS   X   PKG   of  MySQL  installs  itself  into
   /usr/local/mysql-VERSION  and also installs a symbolic link,
   /usr/local/mysql, that points to the new location. If a directory
   named    /usr/local/mysql   exists,   it   is   renamed   to
   /usr/local/mysql.bak first. Additionally, the installer creates
   the   grant  tables  in  the  mysql  database  by  executing
   mysql_install_db.

   The installation layout is similar to that of a tar file binary
   distribution; all MySQL binaries are located in the directory
   /usr/local/mysql/bin.  The  MySQL  socket file is created as
   /tmp/mysql.sock by default. See Section 2.4.6, "Installation
   Layouts."

   MySQL installation requires a Mac OS X user account named mysql. A
   user account with this name should exist by default on Mac OS X
   10.2 and up.

   If you are running Mac OS X Server, a version of MySQL should
   already be installed. The following table shows the versions of
   MySQL that ship with Mac OS X Server versions.
   Mac OS X Server Version MySQL Version
   10.2-10.2.2             3.23.51
   10.2.3-10.2.6           3.23.53
   10.3                    4.0.14
   10.3.2                  4.0.16
   10.4.0                  4.1.10a

   This manual section covers the installation of the official MySQL
   Mac OS X PKG only. Make sure to read Apple's help information
   about installing MySQL: Run the "Help View" application, select
   "Mac OS X Server" help, do a search for "MySQL," and read the item
   entitled "Installing MySQL."

   For  preinstalled versions of MySQL on Mac OS X Server, note
   especially that you should start mysqld with safe_mysqld instead
   of mysqld_safe if MySQL is older than version 4.0.

   If you previously used Marc Liyanage's MySQL packages for Mac OS X
   from http://www.entropy.ch, you can simply follow the update
   instructions for packages using the binary installation layout as
   given on his pages.

   If you are upgrading from Marc's 3.23.x versions or from the Mac
   OS X Server version of MySQL to the official MySQL PKG, you also
   need to convert the existing MySQL privilege tables to the current
   format, because some new security privileges have been added. See
   Section 4.4.9, "mysql_upgrade --- Check Tables for MySQL Upgrade."

   If you want MySQL to start automatically during system startup,
   you also need to install the MySQL Startup Item. It is part of the
   Mac OS X installation disk images as a separate installation
   package. Simply double-click the MySQLStartupItem.pkg icon and
   follow the instructions to install it. The Startup Item need be
   installed only once. There is no need to install it each time you
   upgrade the MySQL package later.

   The    Startup    Item   for   MySQL   is   installed   into
   /Library/StartupItems/MySQLCOM. (Before MySQL 4.1.2, the location
   was /Library/StartupItems/MySQL, but that collided with the MySQL
   Startup  Item  installed  by  Mac OS X Server.) Startup Item
   installation  adds  a  variable MYSQLCOM=-YES- to the system
   configuration file /etc/hostconfig. If you want to disable the
   automatic  startup  of MySQL, simply change this variable to
   MYSQLCOM=-NO-.

   On  Mac OS X Server, the default MySQL installation uses the
   variable MYSQL in the /etc/hostconfig file. The MySQL AB Startup
   Item installer disables this variable by setting it to MYSQL=-NO-.
   This avoids boot time conflicts with the MYSQLCOM variable used by
   the  MySQL AB Startup Item. However, it does not shut down a
   running MySQL server. You should do that yourself.

   After the installation, you can start up MySQL by running the
   following  commands  in  a  terminal  window.  You must have
   administrator privileges to perform this task.

   If you have installed the Startup Item, use this command:
shell> sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
(Enter your password, if necessary)
(Press Control-D or enter "exit" to exit the shell)

   If you don't use the Startup Item, enter the following command
   sequence:
shell> cd /usr/local/mysql
shell> sudo ./bin/mysqld_safe
(Enter your password, if necessary)
(Press Control-Z)
shell> bg
(Press Control-D or enter "exit" to exit the shell)

   You should be able to connect to the MySQL server, for example, by
   running /usr/local/mysql/bin/mysql.

Note

   The accounts that are listed in the MySQL grant tables initially
   have no passwords. After starting the server, you should set up
   passwords for them using the instructions in Section 2.4.16,
   "Post-Installation Setup and Testing."

   You might want to add aliases to your shell's resource file to
   make it easier to access commonly used programs such as mysql and
   mysqladmin from the command line. The syntax for bash is:
alias mysql=/usr/local/mysql/bin/mysql
alias mysqladmin=/usr/local/mysql/bin/mysqladmin

   For tcsh, use:
alias mysql /usr/local/mysql/bin/mysql
alias mysqladmin /usr/local/mysql/bin/mysqladmin

   Even better, add /usr/local/mysql/bin to your PATH environment
   variable. You can do this by modifying the appropriate startup
   file for your shell. For more information, see Section 4.2.1,
   "Invoking MySQL Programs."

   If  you  are  upgrading  an existing installation, note that
   installing a new MySQL PKG does not remove the directory of an
   older installation. Unfortunately, the Mac OS X Installer does not
   yet  offer  the  functionality  required to properly upgrade
   previously installed packages.

   To use your existing databases with the new installation, you'll
   need to copy the contents of the old data directory to the new
   data directory. Make sure that neither the old server nor the new
   one is running when you do this. After you have copied over the
   MySQL database files from the previous installation and have
   successfully started the new server, you should consider removing
   the old installation files to save disk space. Additionally, you
   should  also  remove  older  versions of the Package Receipt
   directories located in /Library/Receipts/mysql-VERSION.pkg.

2.4.11. Installing MySQL on Solaris

   If  you install MySQL using a binary tarball distribution on
   Solaris, you may run into trouble even before you get the MySQL
   distribution unpacked, as the Solaris tar cannot handle long
   filenames. This means that you may see errors when you try to
   unpack MySQL.

   If  this  occurs,  you must use GNU tar (gtar) to unpack the
   distribution. You can find a precompiled copy for Solaris at
   http://dev.mysql.com/downloads/os-solaris.html.

   You can install MySQL on Solaris using a binary package in PKG
   format  instead  of  the binary tarball distribution. Before
   installing using the binary PKG format, you should create the
   mysql user and group, for example:
groupadd mysql
useradd -g mysql mysql

   Some basic PKG-handling commands follow:
     * To add a package:
pkgadd -d package_name.pkg
     * To remove a package:
pkgrm package_name
     * To get a full list of installed packages:
pkginfo
     * To get detailed information for a package:
pkginfo -l package_name
     * To list the files belonging to a package:
pkgchk -v package_name
     * To get packaging information for an arbitrary file:
pkgchk -l -p file_name

   For additional information about installing MySQL on Solaris, see
   Section 2.4.19.3, "Solaris Notes."

2.4.12. Installing MySQL on i5/OS

   The i5/OS POWER MySQL package was created in cooperation with IBM.
   MySQL works within the Portable Application Solution Environment
   (PASE) on the System i series of hardware and will also provide
   database services for the Zend Core for i5/OS.

   MySQL for i5/OS is provided as a save file (.savf) package that
   can be downloaded and installed directly without any additional
   installation steps required.

   MySQL is only supported on i5/OS V5R4 or later releases. The i5/OS
   PASE must be installed for MySQL to operate. You must be able to
   login as a user in *SECOFR class.

   You  should the installation notes and tips for i5/OS before
   starting installation. See i5/OS Installation Notes.

Note

   The installation package will use an existing configuration if you
   have previously installed MySQL (which is identified by looking
   for the file /etc/my.cnf). The values for the data directory
   (DATADIR) and owner of the MySQL files (USRPRF) specified during
   the installation will be ignored, and the values determined from
   the /etc/my.cnf will be used instead.

   If you want to change these parameters during a new install, you
   should temporarily rename /etc/my.cnf, install MySQL using the new
   parameters  you  want  to  use, and then merge your previous
   /etc/my.cnf configuration settings with the new /etc/my.cnf file
   that is created during installation.

   To install MySQL on i5/OS, follow these steps:
    1. Create a user profile MYSQL. The MYSQL user profile will own
       all the MySQL files and databases and be the active user used
       when  the MySQL server is running. The profile should be
       disabled so that you cannot log in as the MySQL user. To
       create a user profile, use CRTUSRPRF:
CRTUSRPRF USRPRF(MYSQL) STATUS(*DISABLED) TEXT('MySQL user id')
    2. On the System i machine, create a save file that will be used
       to receive the downloaded installation save file. The file
       should be located within the General Purpose Library (QGPL):
CRTSAVF FILE(QGPL/MYSQLINST)
    3. Download  the  MySQL  installation  save  file in 32-bit
       (mysql-5.0.42-i5os-power-32bit.savf)      or      64-bit
       (mysql-5.0.42-i5os-power-64bit.savf) from MySQL Downloads
       (http://dev.mysql.com/downloads).
    4. You need to FTP the downloaded .savf file directly into the
       QGPL/MYSQLINST file on the System i server. You can do this
       through FTP using the following steps after logging in to the
       System i machine:
ftp> bin
ftp> cd qgpl
ftp> put mysql-5.0.42-i5os-power.savf mysqlinst
    5. Log into the System i server using a user in the *SECOFR
       class, such as the QSECOFR user ID.
    6. You need to restore the installation library stored in the
       .savf save file:
RSTLIB MYSQLINST DEV(*SAVF) SAVF(QGPL/MYSQLINST)
    7. You   need   to   execute   the   installation  command,
       MYSQLINST/INSMYSQL. You can specify three parameter settings
       during installation:
          + DIR('/opt/mysql') sets the installation location for the
            MySQL files. The directory will be created if it does not
            already exist.
          + DATADIR('/QOpenSys/mysal/data') sets the location of the
            directory that will be used to store the database files
            and   binary   logs.   The   default   setting   is
            /QOpenSys/mysql/data. Note that if the installer detects
            an  existing  installation (due to the existence of
            /etc/my.cnf), then this parameter will be ignored.
          + USRPRF(MYSQL) sets the user profile that will own the
            files that are installed. The profile will be created if
            it does not already exist.
       MySQL can be installed anywhere, for this example we will
       assume MySQL has been installed into /opt/mysql. The MYSQL
       user profile that was created earlier in this sequence should
       be used for the profile:
MYSQLINST/INSMYSQL DIR('/opt/mysql') DATADIR('/opt/mysqldata') USRPRF
(MYSQL)
       If you are updating an installation over an existing MySQL
       installation, you should use the same parameter values that
       were used when MySQL was originally installed.
       The  installation  copies all the necessary files into a
       directory  matching  the  package  version  (for example
       mysql-5.0.42-i5os-power-32bit), sets the ownership on those
       files, sets up the MySQL environment and creates the MySQL
       configuration file (in /etc/my.cnf) completing all the steps
       in a typical binary installation process automatically. If
       this is a new installation of MySQL, or if the installer
       detects that this is a new version (because the /etc/my.cnf
       file does not exist), then the initial core MySQL databases
       will also be created during installation.
    8. Once  the installation has completed, you can delete the
       installation file:
DLTLIB LIB(MYSQLINST)

   To start MySQL:
    1. Log into the System i server using a user within the *SECOFR
       class, such as the QSECOFR user ID.

Note
       You should start mysqld_safe using a user that in the PASE
       environment has the id=0 (the equivalent of the standard Unix
       root user). If you do not use a user with this ID then the
       system will be unable to change the user when executing mysqld
       as set using --user option. If this happens, mysqld may be
       unable  to  read the files located within the MySQL data
       directory and the execution will fail.
    2. Enter the PASE environment using call qp2term.
    3. Start  the  MySQL server by changing to the installation
       directory and running mysqld_safe, specifying the user name
       used  to  install the server. The installer conveniently
       installs  a  symbolic link to the installation directory
       (mysql-5.0.42-i5os-power-32bit) as /opt/mysql/mysql:
> cd /opt/mysql/mysql
> bin/mysqld_safe --user=mysql &
       You should see a message similar to the following:
Starting mysqld daemon with databases ��
     from /opt/mysql/mysql-enterprise-5.0.42-i5os-power-32bit/data

   If you are having problems starting MySQL server, see Section
   2.4.16.2.3, "Starting and Troubleshooting the MySQL Server."

   To stop MySQL:
    1. Log into the System i server using the *SECOFR class, such as
       the QSECOFR user ID.
    2. Enter the PASE environment using call qp2term.
    3. Stop  the MySQL server by changing into the installation
       directory and running mysqladmin, specifying the user name
       used to install the server:
> cd /opt/mysql/mysql
> bin/mysqladmin -u root shutdown
       If the session that you started and stopped MySQL are the
       same, you may get the log output from mysqld:
   STOPPING server from pid file ��
     /opt/mysql/mysql-enterprise-5.0.42-i5os-power-32bit/data/I5DBX.R
CHLAND.IBM.COM.pid
   070718 10:34:20  mysqld ended
       If the sessions used to start and stop MySQL are different,
       you will not receive any confirmation of the shutdown.

   Note and tips
     * A problem has been identified with the installation process on
       DBCS systems. If you are having problems install MySQL on a
       DBCS system, you need to change your job's coded character set
       identifier (CSSID) to 37 (EBCDIC) before executing the install
       command, INSMYSQL. To do this, determine your existing CSSID
       (using  DSPJOB  and  selecting option 2), execute CHGJOB
       CSSID(37), run INSMYSQL to install MySQL and then execute
       CHGJOB again with your original CSSID.
     * If you want to use the Perl scripts that are included with
       MySQL, you need to download the iSeries Tools for Developers
       (5799-PTL). See
       http://www-03.ibm.com/servers/enable/site/porting/tools/.

2.4.13. Installing MySQL on NetWare

   This section does not apply to MySQL Enterprise Server users.

   Porting MySQL to NetWare was an effort spearheaded by Novell.
   Novell customers should be pleased to note that NetWare 6.5 ships
   with bundled MySQL binaries, complete with an automatic commercial
   use license for all servers running that version of NetWare.

   MySQL for NetWare is compiled using a combination of Metrowerks
   CodeWarrior for NetWare and special cross-compilation versions of
   the GNU autotools.

   The  latest  binary  packages for NetWare can be obtained at
   http://dev.mysql.com/downloads/. See Section 2.4.4, "How to Get
   MySQL."

   To host MySQL, the NetWare server must meet these requirements:
     * The    latest    Support    Pack    of    NetWare    6.5
       (http://support.novell.com/filefinder/18197/index.html)must
       be installed.
     * The system must meet Novell's minimum requirements to run the
       respective version of NetWare.
     * MySQL data and the program binaries must be installed on an
       NSS volume; traditional volumes are not supported.

   To install MySQL for NetWare, use the following procedure:
    1. If you are upgrading from a prior installation, stop the MySQL
       server.  This is done from the server console, using the
       following command:
SERVER:  mysqladmin -u root shutdown

Note
       If the MySQL root user account has a password, you need to
       invoke mysqladmin with the -p option and supply the password
       when prompted.
    2. Log on to the target server from a client machine with access
       to the location where you are installing MySQL.
    3. Extract the binary package Zip file onto the server. Be sure
       to allow the paths in the Zip file to be used. It is safe to
       simply extract the file to SYS:\.
       If you are upgrading from a prior installation, you may need
       to copy the data directory (for example, SYS:MYSQL\DATA), as
       well as my.cnf, if you have customized it. You can then delete
       the old copy of MySQL.
    4. You might want to rename the directory to something more
       consistent and easy to use. The examples in this manual use
       SYS:MYSQL to refer to the installation directory.
       Note that MySQL installation on NetWare does not detect if a
       version of MySQL is already installed outside the NetWare
       release. Therefore, if you have installed the latest MySQL
       version from the Web (for example, MySQL 4.1 or later) in
       SYS:\MYSQL, you must rename the folder before upgrading the
       NetWare server; otherwise, files in SYS:\MySQL are overwritten
       by the MySQL version present in NetWare Support Pack.
    5. At the server console, add a search path for the directory
       containing the MySQL NLMs. For example:
SERVER:  SEARCH ADD SYS:MYSQL\BIN
    6. Initialize  the  data directory and the grant tables, if
       necessary,  by  executing mysql_install_db at the server
       console.
    7. Start  the  MySQL server using mysqld_safe at the server
       console.
    8. To finish the installation, you should also add the following
       commands  to  autoexec.ncf.  For  example, if your MySQL
       installation is in SYS:MYSQL and you want MySQL to start
       automatically, you could add these lines:
#Starts the MySQL 5.0.x database server
SEARCH ADD SYS:MYSQL\BIN
MYSQLD_SAFE
       If you are running MySQL on NetWare 6.0, we strongly suggest
       that you use the --skip-external-locking option on the command
       line:
#Starts the MySQL 5.0.x database server
SEARCH ADD SYS:MYSQL\BIN
MYSQLD_SAFE --skip-external-locking
       It is also necessary to use CHECK TABLE and REPAIR TABLE
       instead of myisamchk, because myisamchk makes use of external
       locking. External locking is known to have problems on NetWare
       6.0; the problem has been eliminated in NetWare 6.5. Note that
       the use of MySQL on Netware 6.0 is not officially supported.
       mysqld_safe on NetWare provides a screen presence. When you
       unload (shut down) the mysqld_safe NLM, the screen does not go
       away by default. Instead, it prompts for user input:
*<NLM has terminated; Press any key to close the screen>*
       If you want NetWare to close the screen automatically instead,
       use the --autoclose option to mysqld_safe. For example:
#Starts the MySQL 5.0.x database server
SEARCH ADD SYS:MYSQL\BIN
MYSQLD_SAFE --autoclose
       The behavior of mysqld_safe on NetWare is described further in
       Section 4.3.2, "mysqld_safe --- MySQL Server Startup Script."
    9. When installing MySQL, either for the first time or upgrading
       from a previous version, download and install the latest and
       appropriate Perl module and PHP extensions for NetWare:
          + Perl:
            http://forge.novell.com/modules/xfcontent/downloads.php/p
            erl/Modules/
          + PHP:
            http://forge.novell.com/modules/xfcontent/downloads.php/p
            hp/Modules/

   If there was an existing installation of MySQL on the NetWare
   server, be sure to check for existing MySQL startup commands in
   autoexec.ncf, and edit or delete them as necessary.

Note

   The accounts that are listed in the MySQL grant tables initially
   have no passwords. After starting the server, you should set up
   passwords for them using the instructions in Section 2.4.16,
   "Post-Installation Setup and Testing."

2.4.14. Installing MySQL from tar.gz Packages on Other Unix-Like
Systems

   This section does not apply to MySQL Enterprise Server users.

   This section covers the installation of MySQL binary distributions
   that are provided for various platforms in the form of compressed
   tar files (files with a .tar.gz extension). See Section 2.4.3.4,
   "MySQL Binaries Compiled by MySQL AB," for a detailed list.

   To obtain MySQL, see Section 2.4.4, "How to Get MySQL."

   MySQL  tar  file binary distributions have names of the form
   mysql-VERSION-OS.tar.gz, where VERSION is a number (for example,
   5.0.68), and OS indicates the type of operating system for which
   the distribution is intended (for example, pc-linux-i686).

   In addition to these generic packages, we also offer binaries in
   platform-specific package formats for selected platforms. See
   Section  2.4.7,  "Standard MySQL Installation Using a Binary
   Distribution," for more information on how to install these.

   You need the following tools to install a MySQL tar file binary
   distribution:
     * GNU gunzip to uncompress the distribution.
     * A reasonable tar to unpack the distribution. GNU tar is known
       to work. Some operating systems come with a preinstalled
       version of tar that is known to have problems. For example,
       Mac OS X tar and Sun tar are known to have problems with long
       filenames. On Mac OS X, you can use the preinstalled gnutar
       program. On other systems with a deficient tar, you should
       install GNU tar first.

   If you run into problems and need to file a bug report, please use
   the instructions in Section 1.7, "How to Report Bugs or Problems."

   The basic commands that you must execute to install and use a
   MySQL binary distribution are:
shell> groupadd mysql
shell> useradd -g mysql mysql
shell> cd /usr/local
shell> gunzip < /path/to/mysql-VERSION-OS.tar.gz | tar xvf -
shell> ln -s full-path-to-mysql-VERSION-OS mysql
shell> cd mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> scripts/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql data
shell> bin/mysqld_safe --user=mysql &

Note

   This procedure does not set up any passwords for MySQL accounts.
   After  following  the  procedure, proceed to Section 2.4.16,
   "Post-Installation Setup and Testing."

   A  more  detailed  version  of the preceding description for
   installing a binary distribution follows:
    1. Add a login user and group for mysqld to run as:
shell> groupadd mysql
shell> useradd -g mysql mysql
       These commands add the mysql group and the mysql user. The
       syntax  for  useradd and groupadd may differ slightly on
       different versions of Unix, or they may have different names
       such as adduser and addgroup.
       You might want to call the user and group something else
       instead of mysql. If so, substitute the appropriate name in
       the following steps.
    2. Pick  the  directory  under which you want to unpack the
       distribution and change location into it. In the following
       example, we unpack the distribution under /usr/local. (The
       instructions, therefore, assume that you have permission to
       create files and directories in /usr/local. If that directory
       is protected, you must perform the installation as root.)
shell> cd /usr/local
    3. Obtain a distribution file using the instructions in Section
       2.4.4,  "How  to Get MySQL." For a given release, binary
       distributions for all platforms are built from the same MySQL
       source distribution.
    4. Unpack  the distribution, which creates the installation
       directory. Then create a symbolic link to that directory:
shell> gunzip < /path/to/mysql-VERSION-OS.tar.gz | tar xvf -
shell> ln -s full-path-to-mysql-VERSION-OS mysql
       The tar command creates a directory named mysql-VERSION-OS.
       The ln command makes a symbolic link to that directory. This
       lets you refer more easily to the installation directory as
       /usr/local/mysql.
       With GNU tar, no separate invocation of gunzip is necessary.
       You can replace the first line with the following alternative
       command to uncompress and extract the distribution:
shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz
    5. Change location into the installation directory:
shell> cd mysql
       You will find several files and subdirectories in the mysql
       directory. The most important for installation purposes are
       the bin and scripts subdirectories:
          + The  bin directory contains client programs and the
            server.  You  should  add the full pathname of this
            directory to your PATH environment variable so that your
            shell finds the MySQL programs properly. See Section
            2.4.20, "Environment Variables."
          + The scripts directory contains the mysql_install_db
            script used to initialize the mysql database containing
            the  grant  tables  that  store  the  server access
            permissions.
    6. Ensure that the distribution contents are accessible to mysql.
       If you unpacked the distribution as mysql, no further action
       is required. If you unpacked the distribution as root, its
       contents will be owned by root. Change its ownership to mysql
       by  executing  the  following  commands  as  root in the
       installation directory:
shell> chown -R mysql .
shell> chgrp -R mysql .
       The first command changes the owner attribute of the files to
       the mysql user. The second changes the group attribute to the
       mysql group.
    7. If you have not installed MySQL before, you must create the
       MySQL data directory and initialize the grant tables:
shell> scripts/mysql_install_db --user=mysql
       If you run the command as root, include the --user option as
       shown. If you run the command while logged in as that user,
       you can omit the --user option.
       The command should create the data directory and its contents
       with mysql as the owner.
       After creating or updating the grant tables, you need to
       restart the server manually.
    8. Most of the MySQL installation can be owned by root if you
       like. The exception is that the data directory must be owned
       by mysql. To accomplish this, run the following commands as
       root in the installation directory:
shell> chown -R root .
shell> chown -R mysql data
    9. If you want MySQL to start automatically when you boot your
       machine,  you can copy support-files/mysql.server to the
       location  where  your system has its startup files. More
       information can be found in the support-files/mysql.server
       script  itself  and in Section 2.4.16.2.2, "Starting and
       Stopping MySQL Automatically."
   10. You can set up new accounts using the bin/mysql_setpermission
       script if you install the DBI and DBD::mysql Perl modules. See
       Section 4.6.16, "mysql_setpermission --- Interactively Set
       Permissions in Grant Tables." For Perl module installation
       instructions, see Section 2.4.21, "Perl Installation Notes."
   11. If  you would like to use mysqlaccess and have the MySQL
       distribution in some non-standard location, you must change
       the location where mysqlaccess expects to find the mysql
       client. Edit the bin/mysqlaccess script at approximately line
       18. Search for a line that looks like this:
$MYSQL     = '/usr/local/bin/mysql';    # path to mysql executable
       Change the path to reflect the location where mysql actually
       is stored on your system. If you do not do this, a Broken pipe
       error will occur when you run mysqlaccess.

   After everything has been unpacked and installed, you should test
   your distribution. To start the MySQL server, use the following
   command:
shell> bin/mysqld_safe --user=mysql &

   If you run the command as root, you must use the --user option as
   shown. The value of the option is the name of the login account
   that you created in the first step to use for running the server.
   If you run the command while logged in as mysql, you can omit the
   --user option.

   If the command fails immediately and prints mysqld ended, you can
   find  some information in the host_name.err file in the data
   directory.

   More information about mysqld_safe is given in Section 4.3.2,
   "mysqld_safe --- MySQL Server Startup Script."

Note

   The accounts that are listed in the MySQL grant tables initially
   have no passwords. After starting the server, you should set up
   passwords for them using the instructions in Section 2.4.16,
   "Post-Installation Setup and Testing."

2.4.15. MySQL Installation Using a Source Distribution

   This section does not apply to MySQL Enterprise Server users.

   Before you proceed with an installation from source, first check
   whether our binary is available for your platform and whether it
   works for you. We put a great deal of effort into ensuring that
   our binaries are built with the best possible options.

   To obtain a source distribution for MySQL, Section 2.4.4, "How to
   Get MySQL." If you want to build MySQL from source on Windows, see
   Section 2.4.15.6, "Installing MySQL from Source on Windows."

   MySQL source distributions are provided as compressed tar archives
   and have names of the form mysql-VERSION.tar.gz, where VERSION is
   a number like 5.0.68.

   You need the following tools to build and install MySQL from
   source:
     * GNU gunzip to uncompress the distribution.
     * A reasonable tar to unpack the distribution. GNU tar is known
       to work. Some operating systems come with a preinstalled
       version of tar that is known to have problems. For example,
       the tar provided with early versions of Mac OS X tar, SunOS
       4.x and Solaris 8 and earlier are known to have problems with
       long filenames. On Mac OS X, you can use the preinstalled
       gnutar program. On other systems with a deficient tar, you
       should install GNU tar first.
     * A working ANSI C++ compiler. gcc 2.95.2 or later, SGI C++, and
       SunPro C++ are some of the compilers that are known to work.
       libg++ is not needed when using gcc. gcc 2.7.x has a bug that
       makes it impossible to compile some perfectly legal C++ files,
       such as sql/sql_base.cc. If you have only gcc 2.7.x, you must
       upgrade your gcc to be able to compile MySQL. gcc 2.8.1 is
       also known to have problems on some platforms, so it should be
       avoided if a newer compiler exists for the platform. gcc
       2.95.2 or later is recommended.
     * A good make program. GNU make is always recommended and is
       sometimes required. (BSD make fails, and vendor-provided make
       implementations may fail as well.) If you have problems, we
       recommend GNU make 3.75 or newer.
     * libtool 1.5.24 or later is also recommended.

   If you are using a version of gcc recent enough to understand the
   -fno-exceptions option, it is very important that you use this
   option. Otherwise, you may compile a binary that crashes randomly.
   We also recommend that you use -felide-constructors and -fno-rtti
   along with -fno-exceptions. When in doubt, do the following:
CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors \
       -fno-exceptions -fno-rtti" ./configure \
       --prefix=/usr/local/mysql --enable-assembler \
       --with-mysqld-ldflags=-all-static

   On most systems, this gives you a fast and stable binary.

   If you run into problems and need to file a bug report, please use
   the instructions in Section 1.7, "How to Report Bugs or Problems."

2.4.15.1. Source Installation Overview

   This section does not apply to MySQL Enterprise Server users.

   The basic commands that you must execute to install a MySQL source
   distribution are:
shell> groupadd mysql
shell> useradd -g mysql mysql
shell> gunzip < mysql-VERSION.tar.gz | tar -xvf -
shell> cd mysql-VERSION
shell> ./configure --prefix=/usr/local/mysql
shell> make
shell> make install
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> cd /usr/local/mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> bin/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql var
shell> bin/mysqld_safe --user=mysql &

   If you start from a source RPM, do the following:
shell> rpmbuild --rebuild --clean MySQL-VERSION.src.rpm

   This makes a binary RPM that you can install. For older versions
   of RPM, you may have to replace the command rpmbuild with rpm
   instead.

Note

   This procedure does not set up any passwords for MySQL accounts.
   After  following  the  procedure, proceed to Section 2.4.16,
   "Post-Installation Setup and Testing," for post-installation setup
   and testing.

   A  more  detailed  version  of the preceding description for
   installing MySQL from a source distribution follows:
    1. Add a login user and group for mysqld to run as:
shell> groupadd mysql
shell> useradd -g mysql mysql
       These commands add the mysql group and the mysql user. The
       syntax  for  useradd and groupadd may differ slightly on
       different versions of Unix, or they may have different names
       such as adduser and addgroup.
       You might want to call the user and group something else
       instead of mysql. If so, substitute the appropriate name in
       the following steps.
    2. Perform the following steps as the mysql user, except as
       noted.
    3. Pick  the  directory  under which you want to unpack the
       distribution and change location into it.
    4. Obtain a distribution file using the instructions in Section
       2.4.4, "How to Get MySQL."
    5. Unpack the distribution into the current directory:
shell> gunzip < /path/to/mysql-VERSION.tar.gz | tar xvf -
       This command creates a directory named mysql-VERSION.
       With GNU tar, no separate invocation of gunzip is necessary.
       You can use the following alternative command to uncompress
       and extract the distribution:
shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz
    6. Change location into the top-level directory of the unpacked
       distribution:
shell> cd mysql-VERSION
       Note that currently you must configure and build MySQL from
       this top-level directory. You cannot build it in a different
       directory.
    7. Configure the release and compile everything:
shell> ./configure --prefix=/usr/local/mysql
shell> make
       When  you run configure, you might want to specify other
       options. Run ./configure --help for a list of options. Section
       2.4.15.2, "Typical configure Options," discusses some of the
       more useful options.
       If configure fails and you are going to send mail to a MySQL
       mailing list to ask for assistance, please include any lines
       from config.log that you think can help solve the problem.
       Also  include  the  last  couple of lines of output from
       configure. To file a bug report, please use the instructions
       in Section 1.7, "How to Report Bugs or Problems."
       If the compile fails, see Section 2.4.15.4, "Dealing with
       Problems Compiling MySQL," for help.
    8. Install the distribution:
shell> make install
       You might need to run this command as root.
       If you want to set up an option file, use one of those present
       in the support-files directory as a template. For example:
shell> cp support-files/my-medium.cnf /etc/my.cnf
       You might need to run this command as root.
       If you want to configure support for InnoDB tables, you should
       edit the /etc/my.cnf file, remove the # character before the
       option lines that start with innodb_..., and modify the option
       values to be what you want. See Section 4.2.3.2, "Using Option
       Files," and Section 13.2.3, "InnoDB Configuration."
    9. Change location into the installation directory:
shell> cd /usr/local/mysql
   10. If you ran the make install command as root, the installed
       files will be owned by root. Ensure that the installation is
       accessible to mysql by executing the following commands as
       root in the installation directory:
shell> chown -R mysql .
shell> chgrp -R mysql .
       The first command changes the owner attribute of the files to
       the mysql user. The second changes the group attribute to the
       mysql group.
   11. If you have not installed MySQL before, you must create the
       MySQL data directory and initialize the grant tables:
shell> bin/mysql_install_db --user=mysql
       If you run the command as root, include the --user option as
       shown. If you run the command while logged in as mysql, you
       can omit the --user option.
       The command should create the data directory and its contents
       with mysql as the owner.
       After using mysql_install_db to create the grant tables for
       MySQL, you must restart the server manually. The mysqld_safe
       command to do this is shown in a later step.
   12. Most of the MySQL installation can be owned by root if you
       like. The exception is that the data directory must be owned
       by mysql. To accomplish this, run the following commands as
       root in the installation directory:
shell> chown -R root .
shell> chown -R mysql var
   13. If you want MySQL to start automatically when you boot your
       machine,  you can copy support-files/mysql.server to the
       location  where  your system has its startup files. More
       information can be found in the support-files/mysql.server
       script itself; see also Section 2.4.16.2.2, "Starting and
       Stopping MySQL Automatically."
   14. You can set up new accounts using the bin/mysql_setpermission
       script if you install the DBI and DBD::mysql Perl modules. See
       Section 4.6.16, "mysql_setpermission --- Interactively Set
       Permissions in Grant Tables." For Perl module installation
       instructions, see Section 2.4.21, "Perl Installation Notes."

   After  everything  has  been installed, you should test your
   distribution.  To  start the MySQL server, use the following
   command:
shell> /usr/local/mysql/bin/mysqld_safe --user=mysql &

   If you run the command as root, you should use the --user option
   as shown. The value of the option is the name of the login account
   that you created in the first step to use for running the server.
   If you run the command while logged in as that user, you can omit
   the --user option.

   If the command fails immediately and prints mysqld ended, you can
   find  some information in the host_name.err file in the data
   directory.

   More information about mysqld_safe is given in Section 4.3.2,
   "mysqld_safe --- MySQL Server Startup Script."

Note

   The accounts that are listed in the MySQL grant tables initially
   have no passwords. After starting the server, you should set up
   passwords for them using the instructions in Section 2.4.16,
   "Post-Installation Setup and Testing."

2.4.15.2. Typical configure Options

   This section does not apply to MySQL Enterprise Server users.

   The configure script gives you a great deal of control over how
   you configure a MySQL source distribution. Typically you do this
   using options on the configure command line. You can also affect
   configure using certain environment variables. See Section 2.4.20,
   "Environment Variables." For a full list of options supported by
   configure, run this command:
shell> ./configure --help

   A list of the available configure options is provided in the table

   Some of the configure options available are described here:
     * To compile just the MySQL client libraries and client programs
       and not the server, use the --without-server option:
shell> ./configure --without-server
       If you have no C++ compiler, some client programs such as
       mysql cannot be compiled because they require C++.. In this
       case, you can remove the code in configure that tests for the
       C++   compiler   and   then  run  ./configure  with  the
       --without-server option. The compile step should still try to
       build all clients, but you can ignore any warnings about files
       such as mysql.cc. (If make stops, try make -k to tell it to
       continue with the rest of the build even if errors occur.)
     * If you want to build the embedded MySQL library (libmysqld.a),
       use the --with-embedded-server option.
     * If you don't want your log files and database directories
       located  under  /usr/local/var,  use a configure command
       something like one of these:
shell> ./configure --prefix=/usr/local/mysql
shell> ./configure --prefix=/usr/local \
           --localstatedir=/usr/local/mysql/data
       The first command changes the installation prefix so that
       everything is installed under /usr/local/mysql rather than the
       default  of /usr/local. The second command preserves the
       default  installation  prefix, but overrides the default
       location for database directories (normally /usr/local/var)
       and changes it to /usr/local/mysql/data.
       You can also specify the installation directory and data
       directory  locations at server startup time by using the
       --basedir and --datadir options. These can be given on the
       command line or in an MySQL option file, although it is more
       common to use an option file. See Section 4.2.3.2, "Using
       Option Files."
     * If you are using Unix and you want the MySQL socket file
       location to be somewhere other than the default location
       (normally in the directory /tmp or /var/run), use a configure
       command like this:
shell> ./configure \
           --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock
       The socket filename must be an absolute pathname. You can also
       change the location of mysql.sock at server startup by using a
       MySQL option file. See Section B.1.4.5, "How to Protect or
       Change the MySQL Unix Socket File."
     * If  you  want to compile statically linked programs (for
       example,  to  make  a binary distribution, to get better
       performance, or to work around problems with some Red Hat
       Linux distributions), run configure like this:
shell> ./configure --with-client-ldflags=-all-static \
           --with-mysqld-ldflags=-all-static
     * If  you are using gcc and don't have libg++ or libstdc++
       installed, you can tell configure to use gcc as your C++
       compiler:
shell> CC=gcc CXX=gcc ./configure
       When you use gcc as your C++ compiler, it does not attempt to
       link in libg++ or libstdc++. This may be a good thing to do
       even if you have those libraries installed. Some versions of
       them have caused strange problems for MySQL users in the past.
       The following list indicates some compilers and environment
       variable settings that are commonly used with each one.
          + gcc 2.7.2:
CC=gcc CXX=gcc CXXFLAGS="-O3 -felide-constructors"
          + gcc 2.95.2:
CFLAGS="-O3 -mpentiumpro" CXX=gcc CXXFLAGS="-O3 -mpentiumpro \
-felide-constructors -fno-exceptions -fno-rtti"
          + pgcc 2.90.29 or newer:
CFLAGS="-O3 -mpentiumpro -mstack-align-double" CXX=gcc \
CXXFLAGS="-O3 -mpentiumpro -mstack-align-double \
-felide-constructors -fno-exceptions -fno-rtti"
       In most cases, you can get a reasonably optimized MySQL binary
       by using the options from the preceding list and adding the
       following options to the configure line:
--prefix=/usr/local/mysql --enable-assembler \
--with-mysqld-ldflags=-all-static
       The full configure line would, in other words, be something
       like the following for all recent gcc versions:
CFLAGS="-O3 -mpentiumpro" CXX=gcc CXXFLAGS="-O3 -mpentiumpro \
-felide-constructors -fno-exceptions -fno-rtti" ./configure \
--prefix=/usr/local/mysql --enable-assembler \
--with-mysqld-ldflags=-all-static
       The  binaries  we  provide  on  the  MySQL  Web  site at
       http://dev.mysql.com/downloads/ are all compiled with full
       optimization and should be perfect for most users. See Section
       2.4.3.4, "MySQL Binaries Compiled by MySQL AB." There are some
       configuration settings you can tweak to build an even faster
       binary, but these are only for advanced users. See Section
       7.5.6, "How Compiling and Linking Affects the Speed of MySQL."
       If the build fails and produces errors about your compiler or
       linker  not  being  able  to  create  the shared library
       libmysqlclient.so.N (where N is a version number), you can
       work around this problem by giving the --disable-shared option
       to configure. In this case, configure does not build a shared
       libmysqlclient.so.N library.
     * By default, MySQL uses the latin1 (cp1252 West European)
       character  set.  To  change  the  default  set,  use the
       --with-charset option:
shell> ./configure --with-charset=CHARSET
       CHARSET may be one of binary, armscii8, ascii, big5, cp1250,
       cp1251, cp1256, cp1257, cp850, cp852, cp866, cp932, dec8,
       eucjpms, euckr, gb2312, gbk, geostd8, greek, hebrew, hp8,
       keybcs2, koi8r, koi8u, latin1, latin2, latin5, latin7, macce,
       macroman, sjis, swe7, tis620, ucs2, ujis, utf8. See Section
       9.2,  "The  Character  Set  Used  for Data and Sorting."
       (Additional character sets might be available. Check the
       output from ./configure --help for the current list.)
       The default collation may also be specified. MySQL uses the
       latin1_swedish_ci collation by default. To change this, use
       the --with-collation option:
shell> ./configure --with-collation=COLLATION
       To change both the character set and the collation, use both
       the --with-charset and --with-collation options. The collation
       must be a legal collation for the character set. (Use the SHOW
       COLLATION  statement  to  determine which collations are
       available for each character set.)

Warning
       If you change character sets after having created any tables,
       you must run myisamchk -r -q --set-collation=collation_name on
       every MyISAM table. Your indexes may be sorted incorrectly
       otherwise. This can happen if you install MySQL, create some
       tables,  and  then  reconfigure MySQL to use a different
       character set and reinstall it.
       With the configure option --with-extra-charsets=LIST, you can
       define which additional character sets should be compiled into
       the server. LIST is one of the following:
          + A list of character set names separated by spaces
          + complex to include all character sets that can't be
            dynamically loaded
          + all to include all character sets into the binaries
       Clients that want to convert characters between the server and
       the client should use the SET NAMES statement. See Section
       5.1.4,  "Session  System  Variables," and Section 9.1.4,
       "Connection Character Sets and Collations."
     * To configure MySQL with debugging code, use the --with-debug
       option:
shell> ./configure --with-debug
       This causes a safe memory allocator to be included that can
       find  some errors and that provides output about what is
       happening.      See     MySQL     Internals:     Porting
       (http://forge.mysql.com/wiki/MySQL_Internals_Porting).
       As of MySQL 5.0.25, using --with-debug to configure MySQL with
       debugging    support    enables    you    to   use   the
       --debug="d,parser_debug" option when you start the server.
       This causes the Bison parser that is used to process SQL
       statements to dump a parser trace to the server's standard
       error output. Typically, this output is written to the error
       log.
     * If your client programs are using threads, you must compile a
       thread-safe version of the MySQL client library with the
       --enable-thread-safe-client configure option. This creates a
       libmysqlclient_r library with which you should link your
       threaded applications. See Section 26.2.16, "How to Make a
       Threaded Client."
     * Some  features  require  that  the  server be built with
       compression  library support, such as the COMPRESS() and
       UNCOMPRESS() functions, and compression of the client/server
       protocol. The --with-zlib-dir=no|bundled|DIR option provides
       control  for  compression  library support. The value no
       explicitly disables compression support. bundled causes the
       zlib library bundled in the MySQL sources to be used. A DIR
       pathname specifies where to find the compression library
       sources.
     * It is possible to build MySQL 5.0 with large table support
       using the --with-big-tables option, beginning with MySQL
       5.0.4.
       This option causes the variables that store table row counts
       to be declared as unsigned long long rather than unsigned
       long.  This  enables  tables to hold up to approximately
       1.844E+19 ((2^32)^2) rows rather than 2^32 (~4.295E+09) rows.
       Previously  it was necessary to pass -DBIG_TABLES to the
       compiler manually in order to enable this feature.
     * Run configure with the --disable-grant-options option to cause
       the the --bootstrap, --skip-grant-tables, and --init-file
       options  for  mysqld  to  be  disabled. For Windows, the
       configure.js script recognizes the DISABLE_GRANT_OPTIONS flag,
       which has the same effect. The capability is available as of
       MySQL 5.0.34.
     * In MySQL Community Server, this option enables the statement
       profiling capability exposed by the SHOW PROFILE and SHOW
       PROFILES statements. (See Section 12.5.5.25, "SHOW PROFILES
       and SHOW PROFILE Syntax.") The option was added in MySQL
       5.0.37.
     * See Section 2.4.19, "Operating System-Specific Notes," for
       options that pertain to particular operating systems.
     * See Section 5.5.7.2, "Using SSL Connections," for options that
       pertain to configuring MySQL to support secure (encrypted)
       connections.

2.4.15.3. Installing from the Development Source Tree

   This section does not apply to MySQL Enterprise Server users.

Caution

   You should read this section only if you are interested in helping
   us test our new code. If you just want to get MySQL up and running
   on your system, you should use a standard release distribution
   (either a binary or source distribution).

   To obtain the most recent development source tree, you first need
   to download and install Bazaar. You can obtain Bazaar from the
   Bazaar VCS Website (http://bazaar-vcs.org). Bazaar is supported by
   any platform that supports Python, and is therefore compatible
   with any Linux, Unix, Windows or Mac OS X host. Instructions for
   downloading and installing Bazaar on the different platforms are
   available on the Bazaar website.

   All    MySQL    projects    are    hosted    on    Launchpad
   (http://launchpad.net/). MySQL projects, including MySQL server,
   MySQL  Workbench and others are available from the Sun/MySQL
   Engineering   (http://launchpad.net/~mysql)  page.  For  the
   repositories related only to MySQL server, see the MySQL Server
   (http://launchpad.net/mysql-server) page.

   To build under Unix/Linux, you must have the following tools
   installed:
     * GNU make, available from http://www.gnu.org/software/make/.
       Although   some  platforms  come  with  their  own  make
       implementations, it is highly recommended that you use GNU
       make. It may already be available on your system as gmake.
     * autoconf     2.58    (or    newer),    available    from
       http://www.gnu.org/software/autoconf/.
     * automake 1.8.1, available from
       http://www.gnu.org/software/automake/.
     * libtool 1.5, available from
       http://www.gnu.org/software/libtool/.
     * m4, available from http://www.gnu.org/software/m4/.
     * bison, available from http://www.gnu.org/software/bison/. You
       should use the latest version of bison where possible. Version
       1.75  and version 2.1 are known to work. There have been
       reported  problems  with  bison 1.875. If you experience
       problems, upgrade to a later, rather than earlier, version.
       Versions of bison older than 1.75 may report this error:
sql_yacc.yy:#####: fatal error: maximum table size (32767) exceeded
       The maximum table size is not actually exceeded; the error is
       caused by bugs in older versions of bison.

   To build under Windows you will need a copy of Microsoft Visual
   C++ 2005 Express Edition, Visual Studio .Net 2003 (7.1), or Visual
   Studio 2005 (8.0) compiler system.

   Once you have the necessary tools installed, you first need to
   create a local branch of the MySQL source code on your machine:
    1. To obtain a copy of the MySQL source code, you must create a
       new  Bazaar  branch. If you do not already have a Bazaar
       repository directory set up, you need to initialize a new
       directory:
shell> mkdir mysql-server
shell> bzr init-repo --trees mysql-server
       Once you have an initialized directory, you can branch from
       the public MySQL server repositories. To create a branch of a
       specific version:
shell> cd mysql-server
shell> bzr branch lp:mysql-server/5.0 mysql-5.0
       The  initial  download  will take some time to complete,
       depending on the speed of your connection. Please be patient.
       Once you have downloaded the first tree, additional trees
       should take significantly less time to download.
       When building from the Bazaar branch, you may want to create a
       copy of your active branch so that you can make configuration
       and  other changes without affecting the original branch
       contents. You can achieve this by branching from the original
       branch:
shell> bzr branch mysql-5.0 mysql-5.0-build

   Once you have the local branch, you can start to build MySQL
   server from the source code. On Windows, the build process is
   different from Unix/Linux. To continue building MySQL on Windows,
   see Section 2.4.15.6, "Installing MySQL from Source on Windows."

   On Unix/Linux you need to use the autoconf system to create the
   configure script so that you can configure the build environment
   before building.
    1. The following example shows the typical commands required to
       configure a source tree. The first cd command changes location
       into the top-level directory of the tree; replace mysql-5.0
       with the appropriate directory name.

Note
       For MySQL 5.1.12 and earlier, you must separately configure
       the INNODB storage engine. You can do this by running the
       following command from the main source directory:
shell> cd mysql-5.0
shell> (cd bdb/deist; sh s_all)
shell> (cd innobase; autoreconf --force --install)
shell> autoreconf --force --install
shell> ./configure  # Add your favorite options here
shell> make
       Or  you  can  use BUILD/autorun.sh as a shortcut for the
       following sequence of commands:
shell> aclocal; autoheader
shell> libtoolize --automake --force
shell> automake --force --add-missing; autoconf
shell> (cd bdb/deist; sh s_all)
shell> (cd innobase; aclocal; autoheader; autoconf; automake)
       The   command  line  that  changes  directory  into  the
       storage/innobase directory is used to configure the InnoDB
       storage engine. You can omit this lines if you do not require
       InnoDB support.
       If you get some strange errors during this stage, verify that
       you have the correct version of the libtool installed.
       A collection of our standard configuration scripts is located
       in the BUILD/ subdirectory. For example, you may find it more
       convenient to use the BUILD/compile-pentium-debug script than
       the preceding set of shell commands. To compile on a different
       architecture, modify the script by removing flags that are
       Pentium-specific, or use another script that may be more
       appropriate. These scripts are provided on an "as-is" basis.
       They are not officially maintained and their contents may
       change from release to release.
    2. When the build is done, run make install. Be careful with this
       on a production machine; the command may overwrite your live
       release installation. If you have another installation of
       MySQL, we recommend that you run ./configure with different
       values    for   the   --prefix,   --with-tcp-port,   and
       --unix-socket-path options than those used for your production
       server.
    3. Play hard with your new installation and try to make the new
       features  crash. Start by running make test. See Section
       28.1.2, "MySQL Test Suite."
    4. If you have gotten to the make stage, but the distribution
       does not compile, please enter the problem into our bugs
       database using the instructions given in Section 1.7, "How to
       Report Bugs or Problems." If you have installed the latest
       versions of the required GNU tools, and they crash trying to
       process our configuration files, please report that also.
       However, if you execute aclocal and get a command not found
       error or a similar problem, do not report it. Instead, make
       sure that all the necessary tools are installed and that your
       PATH variable is set correctly so that your shell can find
       them.
    5. After initially copying the repository with bzr to obtain the
       source tree, you should use pull option to periodically update
       your local copy. To do this any time after you have set up the
       repository, use this command:
shell> bzr pull
    6. You can examine the changeset comments for the tree by using
       the log option to bzr:
shell> bzr log
       You can also browse changesets, comments, and source code
       online.  To browse this information for MySQL 5.0, go to
       http://launchpad.net/mysql-server/.
       If you see diffs or code that you have a question about, do
       not hesitate to send email to the MySQL internals mailing
       list. See Section 1.6.1, "MySQL Mailing Lists." Also, if you
       think you have a better idea on how to do something, send an
       email message to the list with a patch.

2.4.15.4. Dealing with Problems Compiling MySQL

   This section does not apply to MySQL Enterprise Server users.

   All MySQL programs compile cleanly for us with no warnings on
   Solaris or Linux using gcc. On other systems, warnings may occur
   due to differences in system include files. See Section 2.4.15.5,
   "MIT-pthreads Notes," for warnings that may occur when using
   MIT-pthreads. For other problems, check the following list.

   The solution to many problems involves reconfiguring. If you do
   need to reconfigure, take note of the following:
     * If configure is run after it has previously been run, it may
       use  information  that  was gathered during its previous
       invocation. This information is stored in config.cache. When
       configure starts up, it looks for that file and reads its
       contents if it exists, on the assumption that the information
       is  still  correct.  That assumption is invalid when you
       reconfigure.
     * Each  time you run configure, you must run make again to
       recompile. However, you may want to remove old object files
       from previous builds first because they were compiled using
       different configuration options.

   To prevent old configuration information or object files from
   being used, run these commands before re-running configure:
shell> rm config.cache
shell> make clean

   Alternatively, you can run make distclean.

   The following list describes some of the problems when compiling
   MySQL that have been found to occur most often:
     * If you get errors such as the ones shown here when compiling
       sql_yacc.cc, you probably have run out of memory or swap
       space:
Internal compiler error: program cc1plus got fatal signal 11
Out of virtual memory
Virtual memory exhausted
       The problem is that gcc requires a huge amount of memory to
       compile  sql_yacc.cc  with inline functions. Try running
       configure with the --with-low-memory option:
shell> ./configure --with-low-memory
       This option causes -fno-inline to be added to the compile line
       if you are using gcc and -O0 if you are using something else.
       You should try the --with-low-memory option even if you have
       so  much  memory and swap space that you think you can't
       possibly have run out. This problem has been observed to occur
       even on systems with generous hardware configurations, and the
       --with-low-memory option usually fixes it.
     * By default, configure picks c++ as the compiler name and GNU
       c++ links with -lg++. If you are using gcc, that behavior can
       cause problems during configuration such as this:
configure: error: installation or configuration problem:
C++ compiler cannot create executables.
       You might also observe problems during compilation related to
       g++, libg++, or libstdc++.
       One cause of these problems is that you may not have g++, or
       you may have g++ but not libg++, or libstdc++. Take a look at
       the config.log file. It should contain the exact reason why
       your C++ compiler didn't work. To work around these problems,
       you  can  use  gcc as your C++ compiler. Try setting the
       environment variable CXX to "gcc -O3". For example:
shell> CXX="gcc -O3" ./configure
       This works because gcc compiles C++ source files as well as
       g++ does, but does not link in libg++ or libstdc++ by default.
       Another way to fix these problems is to install g++, libg++,
       and libstdc++. However, we recommend that you not use libg++
       or libstdc++ with MySQL because this only increases the binary
       size of mysqld without providing any benefits. Some versions
       of these libraries have also caused strange problems for MySQL
       users in the past.
     * If  your  compile  fails  with errors such as any of the
       following, you must upgrade your version of make to GNU make:
making all in mit-pthreads
make: Fatal error in reader: Makefile, line 18:
Badly formed macro assignment
       Or:
make: file `Makefile' line 18: Must be a separator (:
       Or:
pthread.h: No such file or directory
       Solaris  and  FreeBSD are known to have troublesome make
       programs.
       GNU make 3.75 is known to work.
     * If  you want to define flags to be used by your C or C++
       compilers,  do  so by adding the flags to the CFLAGS and
       CXXFLAGS environment variables. You can also specify the
       compiler names this way using CC and CXX. For example:
shell> CC=gcc
shell> CFLAGS=-O3
shell> CXX=gcc
shell> CXXFLAGS=-O3
shell> export CC CFLAGS CXX CXXFLAGS
       See Section 2.4.3.4, "MySQL Binaries Compiled by MySQL AB,"
       for a list of flag definitions that have been found to be
       useful on various systems.
     * If you get errors such as those shown here when compiling
       mysqld, configure did not correctly detect the type of the
       last argument to accept(), getsockname(), or getpeername():
cxx: Error: mysqld.cc, line 645: In this statement, the referenced
     type of the pointer value ''length'' is ''unsigned long'',
     which is not compatible with ''int''.
new_sock = accept(sock, (struct sockaddr *)&cAddr, &length);
       To fix this, edit the config.h file (which is generated by
       configure). Look for these lines:
/* Define as the base type of the last arg to accept */
#define SOCKET_SIZE_TYPE XXX
       Change XXX to size_t or int, depending on your operating
       system. (You must do this each time you run configure because
       configure regenerates config.h.)
     * The sql_yacc.cc file is generated from sql_yacc.yy. Normally,
       the build process does not need to create sql_yacc.cc because
       MySQL comes with a pre-generated copy. However, if you do need
       to re-create it, you might encounter this error:
"sql_yacc.yy", line xxx fatal: default action causes potential...
       This is a sign that your version of yacc is deficient. You
       probably need to install bison (the GNU version of yacc) and
       use that instead.
     * On Debian Linux 3.0, you need to install gawk instead of the
       default mawk if you want to compile MySQL with Berkeley DB
       support.
     * If you need to debug mysqld or a MySQL client, run configure
       with the --with-debug option, and then recompile and link your
       clients with the new client library. See MySQL Internals:
       Porting(http://forge.mysql.com/wiki/MySQL_Internals_Porting).
     * If you get a compilation error on Linux (for example, SuSE
       Linux 8.1 or Red Hat Linux 7.3) similar to the following one,
       you probably do not have g++ installed:
libmysql.c:1329: warning: passing arg 5 of `gethostbyname_r' from
incompatible pointer type
libmysql.c:1329: too few arguments to function `gethostbyname_r'
libmysql.c:1329: warning: assignment makes pointer from integer
without a cast
make[2]: *** [libmysql.lo] Error 1
       By default, the configure script attempts to determine the
       correct  number  of  arguments by using g++ (the GNU C++
       compiler). This test yields incorrect results if g++ is not
       installed. There are two ways to work around this problem:
          + Make sure that the GNU C++ g++ is installed. On some
            Linux distributions, the required package is called gpp;
            on others, it is named gcc-c++.
          + Use  gcc  as  your  C++ compiler by setting the CXX
            environment variable to gcc:
export CXX="gcc"
       You must run configure again after making either of those
       changes.

2.4.15.5. MIT-pthreads Notes

   This section does not apply to MySQL Enterprise Server users.

   This  section describes some of the issues involved in using
   MIT-pthreads.

   On Linux, you should not use MIT-pthreads. Use the installed
   LinuxThreads implementation instead. See Section 2.4.19.1, "Linux
   Notes."

   If your system does not provide native thread support, you should
   build MySQL using the MIT-pthreads package. This includes older
   FreeBSD systems, SunOS 4.x, Solaris 2.4 and earlier, and some
   others. See Section 2.4.2, "Operating Systems Supported by MySQL
   Community Server."

   MIT-pthreads is not part of the MySQL 5.0 source distribution. If
   you require this package, you need to download it separately from
   http://dev.mysql.com/Downloads/Contrib/pthreads-1_60_beta6-mysql.t
   ar.gz

   After downloading, extract this source archive into the top level
   of the MySQL source directory. It creates a new subdirectory named
   mit-pthreads.
     * On most systems, you can force MIT-pthreads to be used by
       running configure with the --with-mit-threads option:
shell> ./configure --with-mit-threads
       Building in a non-source directory is not supported when using
       MIT-pthreads because we want to minimize our changes to this
       code.
     * The checks that determine whether to use MIT-pthreads occur
       only during the part of the configuration process that deals
       with the server code. If you have configured the distribution
       using --without-server to build only the client code, clients
       do not know whether MIT-pthreads is being used and use Unix
       socket file connections by default. Because Unix socket files
       do not work under MIT-pthreads on some platforms, this means
       you need to use -h or --host with a value other than localhost
       when you run client programs.
     * When MySQL is compiled using MIT-pthreads, system locking is
       disabled by default for performance reasons. You can tell the
       server to use system locking with the --external-locking
       option. This is needed only if you want to be able to run two
       MySQL servers against the same data files, but that is not
       recommended, anyway.
     * Sometimes the pthread bind() command fails to bind to a socket
       without any error message (at least on Solaris). The result is
       that all connections to the server fail. For example:
shell> mysqladmin version
mysqladmin: connect to server at '' failed;
error: 'Can't connect to mysql server on localhost (146)'
       The solution to this problem is to kill the mysqld server and
       restart it. This has happened to us only when we have forcibly
       stopped the server and restarted it immediately.
     * With MIT-pthreads, the sleep() system call isn't interruptible
       with SIGINT (break). This is noticeable only when you run
       mysqladmin --sleep. You must wait for the sleep() call to
       terminate before the interrupt is served and the process
       stops.
     * When linking, you might receive warning messages like these
       (at least on Solaris); they can be ignored:
ld: warning: symbol `_iob' has differing sizes:
    (file /my/local/pthreads/lib/libpthread.a(findfp.o) value=0x4;
file /usr/lib/libc.so value=0x140);
    /my/local/pthreads/lib/libpthread.a(findfp.o) definition taken
ld: warning: symbol `__iob' has differing sizes:
    (file /my/local/pthreads/lib/libpthread.a(findfp.o) value=0x4;
file /usr/lib/libc.so value=0x140);
    /my/local/pthreads/lib/libpthread.a(findfp.o) definition taken
     * Some other warnings also can be ignored:
implicit declaration of function `int strtoll(...)'
implicit declaration of function `int strtoul(...)'
     * We have not been able to make readline work with MIT-pthreads.
       (This is not necessary, but may be of interest to some.)

2.4.15.6. Installing MySQL from Source on Windows

   This section does not apply to MySQL Enterprise Server users.

   These instructions describe how to build binaries from source for
   MySQL 5.0 on Windows. Instructions are provided for building
   binaries from a standard source distribution or from the Bazaar
   tree that contains the latest development source.

Note

   The instructions here are strictly for users who want to test
   MySQL on Microsoft Windows from the latest source distribution or
   from the Bazaar tree. For production use, MySQL AB does not advise
   using a MySQL server built by yourself from source. Normally, it
   is best to use precompiled binary distributions of MySQL that are
   built specifically for optimal performance on Windows by MySQL AB.
   Instructions for installing binary distributions are available in
   Section 2.4.8, "Installing MySQL on Windows."

   To  build MySQL on Windows from source, you must satisfy the
   following system, compiler, and resource requirements:
     * Windows 2000, Windows XP, or newer version.
       Windows Vista is supported when using Visual Studio 2005
       provided you have installed the following updates:
          + Microsoft Visual Studio 2005 Professional Edition - ENU
            Service Pack 1 (KB926601)
            (http://support.microsoft.com/?kbid=926601)
          + Security  Update  for  Microsoft Visual Studio 2005
            Professional     Edition     -    ENU    (KB937061)
            (http://support.microsoft.com/?kbid=937061)
          + Update for Microsoft Visual Studio 2005 Professional
            Edition - ENU (KB932232)
            (http://support.microsoft.com/?kbid=932232)
     * To build from the standard source distribution, you will need
       CMake, which can be downloaded from http://www.cmake.org.
       After  installing, modify your path to include the cmake
       binary.
     * Microsoft Visual C++ 2005 Express Edition, Visual Studio .Net
       2003 (7.1), or Visual Studio 2005 (8.0) compiler system.
     * If you are using Visual C++ 2005 Express Edition, you must
       also install an appropriate Platform SDK. More information and
       links to downloads for various Windows platforms is available
       from
       http://www.microsoft.com/downloads/details.aspx?familyid=0baf2
       b35-c656-4969-ace8-e4c0c0716adb/.
     * If you are compiling from a Bazaar tree or making changes to
       the  parser,  you  need  bison for Windows, which can be
       downloaded from
       http://gnuwin32.sourceforge.net/packages/bison.htm.Download
       the package labeled "Complete package, excluding sources".
       After installing the package, modify your path to include the
       bison binary and ensure that this binary is accessible from
       Visual Studio.
     * Cygwin might be necessary if you want to run the test script
       or package the compiled binaries and support files into a Zip
       archive.  (Cygwin  is needed only to test or package the
       distribution, not to build it.) Cygwin is available from
       http://cygwin.com.
     * 3GB to 5GB of disk space.

   The   exact   system   requirements   can   be  found  here:
   http://msdn.microsoft.com/vstudio/Previous/2003/sysreqs/default.as
   px and
   http://msdn.microsoft.com/vstudio/products/sysreqs/default.aspx

   There are three solutions available for building from the source
   code on Windows:
     * Build from the standard MySQL source distribution. For this
       you will need CMake and Visual C++ Express Edition or Visual
       Studio. Using this method you can select the storage engines
       that are included in your build. To use this method, see
       Section 2.4.15.6.1, "Building MySQL from the Standard Source
       Distribution."
     * Build from the MySQL Windows source distribution. The Windows
       source distribution includes ready-made Visual Studio solution
       files that enable support for all storage engines (except
       NDB). To build using using method you only need Visual C++
       Express Edition or Visual Studio. To use this method, see
       Section 2.4.15.6.2, "Building MySQL from a Windows Source
       Distribution."
     * Build directly from the Bazaar source repository. For this you
       will need CMake, Visual C++ Express Edition or Visual Studio,
       and bison. For this method you need to create the distribution
       on a Unix system and then copy the generated files to your
       Windows build environment. To use this method, see Section
       2.4.15.6.5, "Creating a Windows Source Package from the Bazaar
       Repository."

   If  you  find something not working as expected, or you have
   suggestions about ways to improve the current build process on
   Windows, please send a message to the win32 mailing list. See
   Section 1.6.1, "MySQL Mailing Lists."

2.4.15.6.1. Building MySQL from the Standard Source Distribution

   This section does not apply to MySQL Enterprise Server users.

   You can build MySQL on Windows by using a combination of cmake and
   Microsoft Visual Studio .NET 2003 (7.1), Micrsofot Visual Studio
   2005 (8.0) or Microsoft Visual C++ 2005 Express Edition. You must
   have the appropriate Microsoft Platform SDK installed.

Note

   To  compile from the source code usin CMake you must use the
   standard source distribution (for example, mysql-5.0.45.tar.gz).
   You build from the same distribution as used to build MySQL on
   Unix, Linux and other platforms. Do not use the Windows Source
   distributions as they do not contain the necessary configuration
   script and other files.

   Follow this procedure to build MySQL:
    1. If you are installing from a packaged source distribution,
       create a work directory (for example, C:\workdir), and unpack
       the source distribution there using WinZip or another Windows
       tool that can read .zip files. This directory is the work
       directory in the following instructions.
    2. If you are installing from a Bazaar tree, the root directory
       of  that  tree  is  the  work directory in the following
       instructions.
    3. Using a command shell, navigate to the work directory and run
       the following command:
C:\workdir>win\configure options
       These options are available:
          + WITH_INNOBASE_STORAGE_ENGINE: Enable the InnoDB storage
            engine.
          + WITH_PARTITION_STORAGE_ENGINE:  Enable user-defined
            partitioning.
          + WITH_ARCHIVE_STORAGE_ENGINE: Enable the ARCHIVE storage
            engine.
          + WITH_BLACKHOLE_STORAGE_ENGINE: Enable the BLACKHOLE
            storage engine.
          + WITH_EXAMPLE_STORAGE_ENGINE: Enable the EXAMPLE storage
            engine.
          + WITH_FEDERATED_STORAGE_ENGINE: Enable the FEDERATED
            storage engine.
          + __NT__: Enable support for named pipes.
          + MYSQL_SERVER_SUFFIX=suffix: Server suffix, default none.
          + COMPILATION_COMMENT=comment: Server comment, default
            "Source distribution".
          + MYSQL_TCP_PORT=port: Server port, default 3306.
          + DISABLE_GRANT_OPTIONS: Disables the the --bootstrap,
            --skip-grant-tables, and --init-file options for mysqld.
            This option is available as of MySQL 5.0.36.
       For example (type the command on one line):
C:\workdir>win\configure WITH_INNOBASE_STORAGE_ENGINE ��
             WITH_PARTITION_STORAGE_ENGINE MYSQL_SERVER_SUFFIX=-pro
    4. From the work directory, execute the win\build-vs8.bat or
       win\build-vs71.bat file, depending on the version of Visual
       Studio you have installed. The script invokes CMake, which
       generates the mysql.sln solution file you will need to build
       MySQL using Visual Studio..
       You can also use win\build-vs8_x64.bat to build the 64-bit
       version of MySQL. However, you cannot build the 64-bit version
       with Visual Studio Express Edition. You must use Visual Studio
       2005 (8.0) or higher.
    5. From the work directory, open the generated mysql.sln file
       with Visual Studio and select the proper configuration using
       the Configuration menu. The menu provides Debug, Release,
       RelwithDebInfo, MinRelInfo options. Then select Solution >
       Build to build the solution.
       The build process will take some time. Please be patient.
       Remember the configuration that you use in this step. It is
       important later when you run the test script because that
       script needs to know which configuration you used.
    6. You should test you build before installation. See Section
       2.4.15.6.4, "Testing a Windows Source Build."
    7. To  install, use the instructions in Section 2.4.15.6.3,
       "Installing MySQL from a Source Build on Windows."

2.4.15.6.2. Building MySQL from a Windows Source Distribution

   This section does not apply to MySQL Enterprise Server users.

   The Windows source distribution includes the necessary solution
   file and the vcproj files required to build each component. Using
   this method you are not able to select the storage engines that
   are included in your build.

Note

   VC++ workspace files for MySQL 4.1 and above are compatible with
   Microsoft Visual Studio 7.1 and tested by MySQL AB staff before
   each release.

   Follow this procedure to build MySQL:
    1. Create a work directory (for example, C:\workdir).
    2. Unpack the source distribution in the aforementioned directory
       using WinZip or another Windows tool that can read .zip files.
    3. Start Visual Studio .Net 2003 (7.1).
    4. From the File menu, select Open Solution....
    5. Open the mysql.sln solution you find in the work directory.
    6. From the Build menu, select Configuration Manager....
    7. In the Active Solution Configuration pop-up menu, select the
       configuration to use. You likely want to use one of nt (normal
       server),  Max  nt  (more engines and features), or Debug
       configuration.
    8. From the Build menu, select Build Solution.
    9. Debug versions of the programs and libraries are placed in the
       client_debug and lib_debug directories. Release versions of
       the programs and libraries are placed in the client_release
       and lib_release directories.
   10. You should test you build before installation. See Section
       2.4.15.6.4, "Testing a Windows Source Build."
   11. To  install, use the instructions in Section 2.4.15.6.3,
       "Installing MySQL from a Source Build on Windows."

2.4.15.6.3. Installing MySQL from a Source Build on Windows

   When you are satisfied that the program you have built is working
   correctly, stop the server. Now you can install the distribution.
   There  are two ways to do this, either by using the supplied
   installation script or by copying the files individually by hand.

   To use the script method you must have Cygwin installed as the
   script is a Shell script. To execute the installation process, run
   the make_win_bin_dist script in the scripts directory of the MySQL
   source distribution (see Section 4.4.2, "make_win_bin_dist ---
   Package MySQL Distribution as ZIP Archive"). This is a shell
   script, so you must have Cygwin installed if you want to use it.
   It creates a Zip archive of the built executables and support
   files that you can unpack to your desired installation location.

   It is also possible to install MySQL by copying directories and
   files manually:
    1. Create the directories where you want to install MySQL. For
       example, to install into C:\mysql, use these commands:
C:\> mkdir C:\mysql
C:\> mkdir C:\mysql\bin
C:\> mkdir C:\mysql\data
C:\> mkdir C:\mysql\share
C:\> mkdir C:\mysql\scripts
       If you want to compile other clients and link them to MySQL,
       you should also create several additional directories:
C:\> mkdir C:\mysql\include
C:\> mkdir C:\mysql\lib
C:\> mkdir C:\mysql\lib\debug
C:\> mkdir C:\mysql\lib\opt
       If you want to benchmark MySQL, create this directory:
C:\> mkdir C:\mysql\sql-bench
       Benchmarking requires Perl support. See Section 2.4.21, "Perl
       Installation Notes."
    2. From the work directory, copy into the C:\mysql directory the
       following directories:
C:\> cd \workdir
C:\workdir> copy client_release\*.exe C:\mysql\bin
C:\workdir> copy client_debug\mysqld.exe C:\mysql\bin\mysqld-debug.ex
e
C:\workdir> xcopy scripts\*.* C:\mysql\scripts /E
C:\workdir> xcopy share\*.* C:\mysql\share /E
       If you want to compile other clients and link them to MySQL,
       you should also copy several libraries and header files:
C:\workdir> copy lib_debug\mysqlclient.lib C:\mysql\lib\debug
C:\workdir> copy lib_debug\libmysql.* C:\mysql\lib\debug
C:\workdir> copy lib_debug\zlib.* C:\mysql\lib\debug
C:\workdir> copy lib_release\mysqlclient.lib C:\mysql\lib\opt
C:\workdir> copy lib_release\libmysql.* C:\mysql\lib\opt
C:\workdir> copy lib_release\zlib.* C:\mysql\lib\opt
C:\workdir> copy include\*.h C:\mysql\include
C:\workdir> copy libmysql\libmysql.def C:\mysql\include
       If you want to benchmark MySQL, you should also do this:
C:\workdir> xcopy sql-bench\*.* C:\mysql\bench /E

   After installation, set up and start the server in the same way as
   for binary Windows distributions. See Section 2.4.8, "Installing
   MySQL on Windows."

2.4.15.6.4. Testing a Windows Source Build

   You should test the server that you have built from source before
   using the distribution.

   To test the server you need to run the built mysqld. By default,
   using the source build examples, the MySQL base directory and data
   directory are C:\mysql and C:\mysql\data. If you want to test your
   server using the source tree root directory and its data directory
   as the base directory and data directory, you need to tell the
   server their pathnames. You can either do this on the command line
   with  the  --basedir  and  --datadir  options, or by placing
   appropriate options in an option file. (See Section 4.2.3.2,
   "Using Option Files.") If you have an existing data directory
   elsewhere that you want to use, you can specify its pathname
   instead.

   When the server is running in standalone fashion or as a service
   based on your configuration, try to connect to it from the mysql
   interactive command-line utility.

   You can also run the standard test script, mysql-test-run.pl. This
   script  is  written in Perl, so you'll need either Cygwin or
   ActiveState Perl to run it. You may also need to install the
   modules required by the script. To run the test script, change
   location into the mysql-test directory under the work directory,
   set the MTR_VS_CONFIG environment variable to the configuration
   you selected earlier (or use the --vs-config option), and invoke
   mysql-test-run.pl. For example (using Cygwin and the bash shell):
shell> cd mysql-test
shell> export MTS_VS_CONFIG=debug
shell> ./mysqltest-run.pl --force --timer
shell> ./mysqltest-run.pl --force --timer --ps-protocol

2.4.15.6.5. Creating a Windows Source Package from the Bazaar
Repository

   This section does not apply to MySQL Enterprise Server users.

   To create a Windows source package from the current Bazaar source
   tree, use the instructions here. This procedure must be performed
   on a system running a Unix or Unix-like operating system because
   some of the configuration and build steps require tools that work
   only on Unix. For example, the following procedure is known to
   work well on Linux.
    1. Copy the Bazaar source tree for MySQL 5.0. For instructions on
       how to do this, see Section 2.4.15.3, "Installing from the
       Development Source Tree."
    2. Configure and build the distribution so that you have a server
       binary  to  work  with. One way to do this is to run the
       following command in the top-level directory of your source
       tree:
shell> ./BUILD/compile-pentium-max
    3. After  making  sure  that  the  build  process completed
       successfully, run the following utility script from top-level
       directory of your source tree:
shell> ./scripts/make_win_src_distribution
       This script creates a Windows source package to be used on
       your Windows system. You can supply different options to the
       script   based   on   your  needs.  See  Section  4.4.3,
       "make_win_src_distribution --- Create Source Distribution for
       Windows," for a list of allowable options.
       By default, make_win_src_distribution creates a Zip-format
       archive with the name mysql-VERSION-win-src.zip, where VERSION
       represents the version of your MySQL source tree.
    4. Copy or upload the Windows source package that you have just
       created  to your Windows machine. To compile it, use the
       instructions in Section 2.4.15.6.2, "Building MySQL from a
       Windows Source Distribution."

2.4.15.7. Compiling MySQL Clients on Windows

   This section does not apply to MySQL Enterprise Server users.

   In  your source files, you should include my_global.h before
   mysql.h:
#include <my_global.h>
#include <mysql.h>

   my_global.h  includes  any  other  files  needed for Windows
   compatibility (such as windows.h) if you compile your program on
   Windows.

   You  can either link your code with the dynamic libmysql.lib
   library,  which is just a wrapper to load in libmysql.dll on
   demand, or link with the static mysqlclient.lib library.

   The MySQL client libraries are compiled as threaded libraries, so
   you should also compile your code to be multi-threaded.

2.4.16. Post-Installation Setup and Testing

   After installing MySQL, there are some issues that you should
   address. For example, on Unix, you should initialize the data
   directory and create the MySQL grant tables. On all platforms, an
   important security concern is that the initial accounts in the
   grant tables have no passwords. You should assign passwords to
   prevent unauthorized access to the MySQL server. Optionally, you
   can create time zone tables to enable recognition of named time
   zones.

   The following sections include post-installation procedures that
   are specific to Windows systems and to Unix systems. Another
   section, Section 2.4.16.2.3, "Starting and Troubleshooting the
   MySQL Server," applies to all platforms; it describes what to do
   if you have trouble getting the server to start. Section 2.4.16.3,
   "Securing  the  Initial MySQL Accounts," also applies to all
   platforms. You should follow its instructions to make sure that
   you have properly protected your MySQL accounts by assigning
   passwords to them.

   When you are ready to create additional user accounts, you can
   find information on the MySQL access control system and account
   management in Section 5.4, "The MySQL Access Privilege System,"
   and Section 5.5, "MySQL User Account Management."

2.4.16.1. Windows Post-Installation Procedures

   On Windows, the data directory and the grant tables do not have to
   be created. MySQL Windows distributions include the grant tables
   with a set of preinitialized accounts in the mysql database under
   the data directory. It is unnecessary to run the mysql_install_db
   script that is used on Unix. Regarding passwords, if you installed
   MySQL using the Windows Installation Wizard, you may have already
   assigned passwords to the accounts. (See Section 2.4.8.3, "Using
   the   MySQL   Installation   Wizard.")  Otherwise,  use  the
   password-assignment procedure given in Section 2.4.16.3, "Securing
   the Initial MySQL Accounts."

   Before setting up passwords, you might want to try running some
   client programs to make sure that you can connect to the server
   and that it is operating properly. Make sure that the server is
   running (see Section 2.4.8.9, "Starting the Server for the First
   Time"), and then issue the following commands to verify that you
   can retrieve information from the server. The output should be
   similar to what is shown here:
C:\> C:\mysql\bin\mysqlshow
+--------------------+
|     Databases      |
+--------------------+
| information_schema |
| mysql              |

+------+-------+------+
| host | db    | user |
+------+-------+------+
| %    | test% |      |
+------+-------+------+

   You may need to specify a different directory from the one shown;
   if you used the Windows Installation Wizard, then the default
   directory is C:\Program Files\MySQL\MySQL Server 5.0, and the
   mysql  and  mysqlshow  client  programs  are  in  C:\Program
   Files\MySQL\MySQL Server 5.0\bin. See Section 2.4.8.3, "Using the
   MySQL Installation Wizard," for more information.

   If you have already secured the initial MySQL accounts, you may
   need  to  use the -u and -p options to supply a username and
   password to the mysqlshow and mysql client programs; otherwise the
   programs may fail with an error, or you may not be able to view
   all databases. For example, if you have assigned the password
   "secretpass"  to the MySQL root account, then you can invoke
   mysqlshowand mysql as shown here:
C:\> C:\mysql\bin\mysqlshow -uroot -psecretpass
+--------------------+
|     Databases      |
+--------------------+

   For more information about these programs, see Section 4.5.6,
   "mysqlshow --- Display Database, Table, and Column Information,"
   and Section 4.5.1, "mysql --- The MySQL Command-Line Tool."

   If you are running a version of Windows that supports services and
   you  want the MySQL server to run automatically when Windows
   starts,  see  Section 2.4.8.11, "Starting MySQL as a Windows
   Service."

2.4.16.2. Unix Post-Installation Procedures

   After installing MySQL on Unix, you need to initialize the grant
   tables, start the server, and make sure that the server works
   satisfactorily. You may also wish to arrange for the server to be
   started and stopped automatically when your system starts and
   stops. You should also assign passwords to the accounts in the
   grant tables.

   On Unix, the grant tables are set up by the mysql_install_db
   program. For some installation methods, this program is run for
   you automatically:
     * If you install MySQL on Linux using RPM distributions, the
       server RPM runs mysql_install_db.
     * If you install MySQL on Mac OS X using a PKG distribution, the
       installer runs mysql_install_db.

   Otherwise, you will need to run mysql_install_db yourself.

   The following procedure describes how to initialize the grant
   tables (if that has not previously been done) and then start the
   server. It also suggests some commands that you can use to test
   whether  the  server is accessible and working properly. For
   information about starting and stopping the server automatically,
   see   Section   2.4.16.2.2,  "Starting  and  Stopping  MySQL
   Automatically."

   After you complete the procedure and have the server running, you
   should   assign   passwords   to  the  accounts  created  by
   mysql_install_db. Instructions for doing so are given in Section
   2.4.16.3, "Securing the Initial MySQL Accounts."

   In the examples shown here, the server runs under the user ID of
   the mysql login account. This assumes that such an account exists.
   Either create the account if it does not exist, or substitute the
   name of a different existing login account that you plan to use
   for running the server.
    1. Change location into the top-level directory of your MySQL
       installation, represented here by BASEDIR:
shell> cd BASEDIR
       BASEDIR is likely to be something like /usr/local/mysql or
       /usr/local. The following steps assume that you are located in
       this directory.
    2. If necessary, run the mysql_install_db program to set up the
       initial MySQL grant tables containing the privileges that
       determine how users are allowed to connect to the server.
       You'll need to do this if you used a distribution type for
       which the installation procedure doesn't run the program for
       you.
       Typically, mysql_install_db needs to be run only the first
       time you install MySQL, so you can skip this step if you are
       upgrading an existing installation, However, mysql_install_db
       does not overwrite any existing privilege tables, so it should
       be safe to run in any circumstances.
       To initialize the grant tables, use one of the following
       commands, depending on whether mysql_install_db is located in
       the bin or scripts directory:
shell> bin/mysql_install_db --user=mysql
shell> scripts/mysql_install_db --user=mysql
       The  mysql_install_db  script  creates the server's data
       directory. Under the data directory, it creates directories
       for the mysql database that holds all database privileges and
       the test database that you can use to test MySQL. The script
       also  creates  privilege  table  entries  for  root  and
       anonymous-user  accounts. The accounts have no passwords
       initially. A description of their initial privileges is given
       in Section 2.4.16.3, "Securing the Initial MySQL Accounts."
       Briefly, these privileges allow the MySQL root user to do
       anything, and allow anybody to create or use databases with a
       name of test or starting with test_.
       It is important to make sure that the database directories and
       files are owned by the mysql login account so that the server
       has read and write access to them when you run it later. To
       ensure this, the --user option should be used as shown if you
       run mysql_install_db as root. Otherwise, you should execute
       the script while logged in as mysql, in which case you can
       omit the --user option from the command.
       mysql_install_db creates several tables in the mysql database,
       including user, db, host, tables_priv, columns_priv, func, and
       others. See Section 5.4, "The MySQL Access Privilege System,"
       for a complete listing and description of these tables.
       If you don't want to have the test database, you can remove it
       with mysqladmin -u root drop test after starting the server.
       If you have trouble with mysql_install_db at this point, see
       Section 2.4.16.2.1, "Problems Running mysql_install_db."
    3. Start the MySQL server:
shell> bin/mysqld_safe --user=mysql &
       It  is  important  that the MySQL server be run using an
       unprivileged (non-root) login account. To ensure this, the
       --user option should be used as shown if you run mysqld_safe
       as system root. Otherwise, you should execute the script while
       logged in to the system as mysql, in which case you can omit
       the --user option from the command.
       Further instructions for running MySQL as an unprivileged user
       are given in Section 5.3.5, "How to Run MySQL as a Normal
       User."
       If you neglected to create the grant tables before proceeding
       to this step, the following message appears in the error log
       file when you start the server:
mysqld: Can't find file: 'host.frm'
       If you have other problems starting the server, see Section
       2.4.16.2.3, "Starting and Troubleshooting the MySQL Server."
    4. Use mysqladmin to verify that the server is running. The
       following commands provide simple tests to check whether the
       server is up and responding to connections:
shell> bin/mysqladmin version
shell> bin/mysqladmin variables
       The output from mysqladmin version varies slightly depending
       on your platform and version of MySQL, but should be similar
       to that shown here:
shell> bin/mysqladmin version
mysqladmin  Ver 14.12 Distrib 5.0.68, for pc-linux-gnu on i686

       To see what else you can do with mysqladmin, invoke it with
       the --help option.
    5. Verify that you can shut down the server:
shell> bin/mysqladmin -u root shutdown
    6. Verify that you can start the server again. Do this by using
       mysqld_safe or by invoking mysqld directly. For example:
shell> bin/mysqld_safe --user=mysql --log &
       If mysqld_safe fails, see Section 2.4.16.2.3, "Starting and
       Troubleshooting the MySQL Server."
    7. Run  some  simple  tests to verify that you can retrieve
       information from the server. The output should be similar to
       what is shown here:

    8. There is a benchmark suite in the sql-bench directory (under
       the MySQL installation directory) that you can use to compare
       how MySQL performs on different platforms. The benchmark suite
       is written in Perl. It requires the Perl DBI module that
       provides a database-independent interface to the various
       databases, and some other additional Perl modules:
DBI
DBD::mysql
Data::Dumper
Data::ShowTable
       These    modules    can    be    obtained    from   CPAN
       (http://www.cpan.org/). See also Section 2.4.21.1, "Installing
       Perl on Unix."
       The sql-bench/Results directory contains the results from many
       runs against different databases and platforms. To run all
       tests, execute these commands:
shell> cd sql-bench
shell> perl run-all-tests
       If  you don't have the sql-bench directory, you probably
       installed MySQL using RPM files other than the source RPM.
       (The source RPM includes the sql-bench benchmark directory.)
       In this case, you must first install the benchmark suite
       before you can use it. There are separate benchmark RPM files
       named mysql-bench-VERSION.i386.rpm that contain benchmark code
       and data.
       If you have a source distribution, there are also tests in its
       tests subdirectory that you can run. For example, to run
       auto_increment.tst, execute this command from the top-level
       directory of your source distribution:
shell> mysql -vvf test < ./tests/auto_increment.tst
       The  expected  result  of  the  test can be found in the
       ./tests/auto_increment.res file.
    9. At this point, you should have the server running. However,
       none of the initial MySQL accounts have a password, so you
       should  assign passwords using the instructions found in
       Section 2.4.16.3, "Securing the Initial MySQL Accounts."

   The MySQL 5.0 installation procedure creates time zone tables in
   the mysql database. However, you must populate the tables manually
   using the instructions in Section 9.7, "MySQL Server Time Zone
   Support."

2.4.16.2.1. Problems Running mysql_install_db

   This section does not apply to MySQL Enterprise Server users.

   The purpose of the mysql_install_db script is to generate new
   MySQL privilege tables. It does not overwrite existing MySQL
   privilege tables, and it does not affect any other data.

   If you want to re-create your privilege tables, first stop the
   mysqld server if it's running. Then rename the mysql directory
   under   the   data  directory  to  save  it,  and  then  run
   mysql_install_db. Suppose that your current directory is the MySQL
   installation directory and that mysql_install_db is located in the
   bin directory and the data directory is named data. To rename the
   mysql database and re-run mysql_install_db, use these commands.
shell> mv data/mysql data/mysql.old
shell> bin/mysql_install_db --user=mysql

   When you run mysql_install_db, you might encounter the following
   problems:
     * mysql_install_db fails to install the grant tables
       You may find that mysql_install_db fails to install the grant
       tables and terminates after displaying the following messages:
Starting mysqld daemon with databases from XXXXXX
mysqld ended
       In this case, you should examine the error log file very
       carefully. The log should be located in the directory XXXXXX
       named by the error message and should indicate why mysqld
       didn't start. If you do not understand what happened, include
       the log when you post a bug report. See Section 1.7, "How to
       Report Bugs or Problems."
     * There is a mysqld process running
       This indicates that the server is running, in which case the
       grant tables have probably been created already. If so, there
       is no need to run mysql_install_db at all because it needs to
       be run only once (when you install MySQL the first time).
     * Installing a second mysqld server does not work when one
       server is running
       This can happen when you have an existing MySQL installation,
       but want to put a new installation in a different location.
       For example, you might have a production installation, but you
       want to create a second installation for testing purposes.
       Generally the problem that occurs when you try to run a second
       server is that it tries to use a network interface that is in
       use by the first server. In this case, you should see one of
       the following error messages:
Can't start server: Bind on TCP/IP port:
Address already in use
Can't start server: Bind on unix socket...
       For instructions on setting up multiple servers, see Section
       5.6, "Running Multiple MySQL Servers on the Same Machine."
     * You do not have write access to the /tmp directory
       If you do not have write access to create temporary files or a
       Unix socket file in the default location (the /tmp directory),
       an error occurs when you run mysql_install_db or the mysqld
       server.
       You  can  specify  different locations for the temporary
       directory and Unix socket file by executing these commands
       prior  to  starting  mysql_install_db  or  mysqld, where
       some_tmp_dir is the full pathname to some directory for which
       you have write permission:
shell> TMPDIR=/some_tmp_dir/
shell> MYSQL_UNIX_PORT=/some_tmp_dir/mysql.sock
shell> export TMPDIR MYSQL_UNIX_PORT
       Then you should be able to run mysql_install_db and start the
       server with these commands:
shell> bin/mysql_install_db --user=mysql
shell> bin/mysqld_safe --user=mysql &
       If mysql_install_db is located in the scripts directory,
       modify the first command to scripts/mysql_install_db.
       See Section B.1.4.5, "How to Protect or Change the MySQL Unix
       Socket File," and Section 2.4.20, "Environment Variables."

   There are some alternatives to running the mysql_install_db script
   provided in the MySQL distribution:
     * If you want the initial privileges to be different from the
