 2.4 Installing MySQL on Linux
 =============================
 
 The recommended way to install MySQL on Linux is by using the RPM
 packages. The MySQL RPMs are currently built on a SuSE Linux 7.3
 system, but should work on most versions of Linux that support `rpm'
 and use `glibc'. To obtain RPM packages, see  getting-mysql.
 
 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.
 
 * 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 
 binary-notes-linux.
 
 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. If you
 want to run a MySQL-Max server that has additional capabilities, you
 should also install the `MySQL-Max' RPM. However, you should do so only
 _ after_ installing the `MySQL-server' RPM. See  mysqld-max.
 
 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.
 
 The following RPM packages are available:
 
    * `MySQL-server-VERSION.i386.rpm'
 
      The MySQL server. You need this unless you only want to connect to
      a MySQL server running on another machine. Note: Server RPM files
      were called `MySQL-VERSION.i386.rpm' before MySQL 4.0.10. That is,
      they did not have `-server' in the name.
 
    * `MySQL-Max-VERSION.i386.rpm'
 
      The MySQL-Max server. This server has additional capabilities that
      the one provided in the `MySQL-server' RPM does not. You must
      install the `MySQL-server' RPM first, because the `MySQL-Max' RPM
      depends on it.
 
    * `MySQL-client-VERSION.i386.rpm'
 
      The standard MySQL client programs. You probably always want to
      install this package.
 
    * `MySQL-bench-VERSION.i386.rpm'
 
      Tests and benchmarks. Requires Perl and the `DBD::mysql' module.
 
    * `MySQL-devel-VERSION.i386.rpm'
 
      The libraries and include files that are needed if you want to
      compile other MySQL clients, such as the Perl modules.
 
    * `MySQL-shared-VERSION.i386.rpm'
 
      This package contains the shared libraries (`libmysqlclient.so*')
      that certain languages and applications need to dynamically load
      and use MySQL.
 
    * `MySQL-shared-compat-VERSION.i386.rpm'
 
      This package includes the shared libraries for both MySQL 3.23 and
      MySQL 4.0. Install this package instead of `MySQL-shared' if you
      have applications installed that are dynamically linked against
      MySQL 3.23 but you want to upgrade to MySQL 4.0 without breaking
      the library dependencies. This package has been available since
      MySQL 4.0.13.
 
    * `MySQL-embedded-VERSION.i386.rpm'
 
      The embedded MySQL server library (available as of MySQL 4.0).
 
    * `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).
 
 To see all files in an RPM package (for example, a `MySQL-server' RPM),
 run a commnd like this:
 
      shell> rpm -qpl MySQL-server-VERSION.i386.rpm
 
 To perform a standard minimal installation, install the server and
 client RPMs:
 
      shell> rpm -i MySQL-server-VERSION.i386.rpm
      shell> rpm -i MySQL-client-VERSION.i386.rpm
 
 To install only the client programs, install just the client RPM:
 
      shell> rpm -i MySQL-client-VERSION.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  verifying-package-integrity.
 
 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  automatic-start, 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  installing-binary.
 
 * 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 
 post-installation.
