The recommended way to install MySQL on RPM-based Linux
distributions is by using the RPM packages. The RPMs that we
provide to the community should work on all versions of Linux that
support RPM packages and use
glibc 2.3. To
obtain RPM packages, see Section 2.1.2, “How to Get MySQL”.
For non-RPM Linux distributions, you can install MySQL using a
.tar.gz package. See
Section 2.2, “Installing MySQL on Unix/Linux Using Generic Binaries”.
Installations created from our Linux RPM distributions result in files under the system directories shown in the following table.
Table 2.15 MySQL Installation Layout for Linux RPM Packages
|Directory||Contents of Directory|
|Client programs and scripts|
|The mysqld server|
|Log files, databases|
|MySQL manual in Info format|
|Unix manual pages|
|Include (header) files|
|Miscellaneous support files, including error messages, character set files, sample configuration files, SQL for database installation|
RPM distributions of MySQL are also provided by other vendors. Be aware that they may differ from those built by Oracle in features, capabilities, and conventions (including communication setup), and that the instructions in this manual do not necessarily apply to installing them. The vendor's instructions should be consulted instead. Because of these differences, RPM packages built by Oracle check whether such RPMs built by other vendors are installed. If so, the RPM does not install and produces a message explaining this.
Conflicts can arise when an RPM from another vendor is already
installed, such as when a vendor's conventions about which files
belong with the server and which belong with the client library
differ from the breakdown used for Oracle packages. In such
cases, attempts to install an Oracle RPM with rpm
-i may result in messages that files in the RPM to be
installed conflict with files from an installed package (denoted
mysql-libs in the following paragraphs).
Each MySQL release provides a
MySQL-shared-compat package that is meant to
mysql-libs and provides a
replacement-compatible client library for older MySQL series.
MySQL-shared-compat is set up to make
mysql-libs obsolete, but
rpm explicitly refuses to replace obsoleted
packages when invoked with
-U), which is why installation with
rpm -i produces a conflict.
MySQL-shared-compat can safely be installed
mysql-libs because libraries are
installed to different locations. Therefore, it is possible to
MySQL-shared-compat first, then
mysql-libs before continuing
with the installation. After
removed, the dynamic linker stops looking for the client library
in the location where
mysql-libs puts it, and
the library provided by the
MySQL-shared-compat package takes over.
Another alternative is to install packages using
yum. In a directory containing all RPM
packages for a MySQL release, yum install
MySQL*rpm installs them in the correct order and
mysql-libs in one step without
In most cases, you need install only the
MySQL-client packages to get a functional
standard MySQL installation. The other packages are not required
for a standard installation.
RPMs for MySQL Cluster.
Beginning with MySQL 5.1.24, standard MySQL server RPMs built by
MySQL no longer provide support for the
NDBCLUSTER storage engine. MySQL
Cluster users should check the MySQL Cluster Downloads page at
http://dev.mysql.com/downloads/cluster/ for RPMs that should
work with most Linux distributions for both of these release
When upgrading a MySQL Cluster RPM installation, you must
upgrade all installed RPMs, including the
For more information about installing MySQL Cluster from RPMs, see Section 22.214.171.124, “Installing MySQL Cluster from RPM”.
For upgrades, if your installation was originally produced by installing multiple RPM packages, it is best to upgrade all the installed packages, not just some. For example, if you previously installed the server and client RPMs, do not upgrade just the server RPM.
The following list shows the available RPM packages. The names
shown here use a suffix of
but particular packages can have different suffixes, described

MySQL-shared-compatpackage if you want to included shared client libraries for older MySQL versions.
The embedded MySQL server library.
Packages that contain additional files for MySQL Cluster installations.Note
MySQL-ndb-toolsRPM requires a working installation of perl. Prior to MySQL 5.1.18, the
HTML::Templatepackages were also required. See Section 2.15, “Perl Installation Notes”, and Section 17.4.24, “ndb_size.pl — NDBCLUSTER Size Requirement Estimator”, for more information.
The MySQL test suite.
The source code for all of the previous packages. It can also be used to rebuild the RPMs on other architectures (for example, SPARC).
In RPM package names, the suffix (following the
VERSION value) has the following
CPU values indicate the type of system
for which the package is built.
PLATFORM indicates the platform and
CPU indicates the processor type or
All packages are dynamically linked against
glibc 2.3. The
PLATFORM value indicates whether the
package is platform independent or intended for a specific
platform, as shown in the following table.
Table 2.16 MySQL Linux RPM Package Platforms
|Platform independent, should run on any Linux distribution that supports
|Red Hat Enterprise Linux 4 or 5|
|SuSE Linux Enterprise Server 10 or 11|
In MySQL 5.1, only
packages are available currently.
CPU value indicates the processor
type or family for which the package is built, as shown in the
Table 2.17 MySQL Linux RPM Package CPU Identifiers
|Intended Processor Type or Family|
|Pentium processor or better, 32 bit|
|64-bit x86 processor|

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

To perform a standard minimal installation, install the server and client RPMs:

rpm -i MySQL-client-
To install only the client programs, install just the client RPM:
rpm -i MySQL-client-
RPM provides a feature to verify the integrity and authenticity of packages before installing them. To learn more about this feature, see Section 2.1.3, “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
(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 can
reinstall it after you install a newer RPM.) See
Section 2.12.5, “Starting and Stopping MySQL Automatically”, for more information on how
MySQL can be started automatically at system startup.
In MySQL 5.1.49 and later, during an upgrade installation using RPM packages, if the MySQL server is running when the upgrade occurs, the MySQL server is stopped, the upgrade occurs, and the MySQL server is restarted. If the MySQL server is not already running when the RPM upgrade occurs, the MySQL server is not started at the end of the installation.
If something goes wrong, you can find more information in the binary installation section. See Section 2.2, “Installing MySQL on Unix/Linux Using Generic Binaries”.
The accounts created in the MySQL grant tables for an RPM installation initially have no passwords. After starting the server, you should assign passwords to them using the instructions in Section 2.12, “Postinstallation Setup and Testing”.
An RPM installation creates a user named
and a group named
mysql on the system using the
useradd, groupadd, and
usermod commands. Those commands require
appropriate administrative privileges, which is required for
locally managed users and groups (as listed in the
/etc/group files) by the RPM installation
process being run by
If you log in as the
mysql user, you may find
that MySQL displays “Invalid (old?) table or database
name” errors that mention
similar files created by MySQL or operating system utilities. You
can safely ignore these error messages or remove the files or
directories that cause them if you do not need them.
For nonlocal user management (LDAP, NIS, and so forth), the administrative tools may require additional authentication (such as a password), and will fail if the installing user does not provide this authentication. Even if they fail, the RPM installation will not abort but succeed, and this is intentional. If they failed, some of the intended transfer of ownership may be missing, and it is recommended that the system administrator then manually ensures some appropriate user and group exists and manually transfers ownership following the actions in the RPM spec file.
