2.2.2 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 How to Get MySQL.

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 Linux Binary Distribution Notes.

In most cases, you only need to install 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 section mysqld-max.

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

Many 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:

To see all files in an RPM package (for example, a MySQL-server RPM), run:

 
shell> rpm -qpl MySQL-server-VERSION.i386.rpm

To perform a standard minimal installation, run:

 
shell> rpm -i MySQL-server-VERSION.i386.rpm
shell> rpm -i MySQL-client-VERSION.i386.rpm

To install just the client package, run:

 
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 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 already 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 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 already 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 now be able to start using MySQL.

If something goes wrong, you can find more information in the binary installation section. See section Installing MySQL 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 Post-Installation Setup and Testing.
