Installing Percona Server for MySQL on Red Hat Enterprise Linux and CentOS

Installing Percona Server for MySQL on Red Hat Enterprise Linux and CentOS

Ready-to-use packages are available from the Percona Server for MySQL software repositories and the download page. The Percona yum repository supports popular RPM-based operating systems, including the Amazon Linux AMI.

The easiest way to install the Percona Yum repository is to install an RPM that configures yum and installs the Percona GPG key.

Specific information on the supported platforms, products, and versions are described in Percona Software and Platform Lifecycle.

What’s in each RPM package?

Each of the Percona Server for MySQL RPM packages have a particular purpose.

The Percona-Server-server-57 package contains the server itself (the mysqld binary).

The Percona-Server-57-debuginfo package contains debug symbols for the server.

The Percona-Server-client-57 package contains the command line client.

The Percona-Server-devel-57 package contains the header files needed to compile software using the client library.

The Percona-Server-shared-57 package includes the client shared library.

The Percona-Server-shared-compat package includes shared libraries for software compiled against old versions of the client library. Following libraries are included in this package: libmysqlclient.so.12, libmysqlclient.so.14, libmysqlclient.so.15, libmysqlclient.so.16, and libmysqlclient.so.18.

The Percona-Server-test-57 package includes the test suite for Percona Server for MySQL.

To install Percona Server for MySQL with SELinux policies, you also need the Percona-Server-selinux-*.noarch.rpm package:

$ yum install http://repo.percona.com/centos/7/RPMS/x86_64/Percona-Server-selinux-57-5.7.31-rel84.2.el7.noarch.rpm

  1. Testing the repository

    Make sure packages are now available from the repository, by executing the following command:

    yum list | grep percona

    You should see output similar to the following:

    ...
Percona-Server-57-debuginfo.x86_64      5.7.31-34.1.el7                 @percona-release-x86_64
Percona-Server-client-57.x86_64         5.7.31-34.1.el7                 @percona-release-x86_64
Percona-Server-devel-57.x86_64          5.7.31-34.1.el7                 @percona-release-x86_64
Percona-Server-server-57.x86_64         5.7.31-34.1.el7                 @percona-release-x86_64
Percona-Server-shared-57.x86_64         5.7.31-34.1.el7                 @percona-release-x86_64

Percona-Server-test-57.x86_64           5.7.31-34.1.el7                 @percona-release-x86_64
Percona-Server-tokudb-57.x86_64         5.7.31-34.1.el7                 @percona-release-x86_64
...

.. note::

For a RHEL 8 package installation, the mysql module must be disabled.

    $ sudo dnf module disable mysql

  2. Install the packages

    You can now install Percona Server for MySQL by running:

    yum install Percona-Server-server-57

Note

Percona Server for MySQL 5.7 comes with the TokuDB storage engine. You can find more information on how to install and enable the TokuDB storage in the TokuDB Installation guide.

Percona yum Testing repository

Percona offers pre-release builds from our testing repository. To subscribe to the testing repository, you’ll need to enable the testing repository in /etc/yum.repos.d/percona-release.repo. To do so, set both percona-testing-$basearch and percona-testing-noarch to enabled = 1 (Note that there are 3 sections in this file: release, testing and experimental - in this case it is the second section that requires updating). NOTE: You’ll need to install the Percona repository first (ref above) if this hasn’t been done already.

Installing Percona Server for MySQL using downloaded rpm packages

  1. Download the packages of the desired series for your architecture from the download page. The easiest way is to download bundle which contains all the packages. Following example will download Percona Server for MySQL 5.7.31-34 release packages for CentOS 7:

    $ wget https://www.percona.com/downloads/Percona-Server-5.7/Percona-Server-5.7.31-34/binary/redhat/7/x86_64/Percona-Server-5.7.31-34-r2e68637-el7-x86_64-bundle.tar

  2. You should then unpack the bundle to get the packages:

    $ tar xvf Percona-Server-5.7.31-34-r2e68637-el7-x86_64-bundle.tar

    After you unpack the bundle you should see the following packages:

    $ ls *.rpm

Percona-Server-57-debuginfo-5.7.31-34.1.el7.x86_64.rpm
Percona-Server-client-57-5.7.31-34.1.el7.x86_64.rpm
Percona-Server-devel-57-5.7.31-34.1.el7.x86_64.rpm
Percona-Server-rocksdb-57-5.7.31-34.1.el7.x86_64.rpm
Percona-Server-server-57-5.7.31-34.1.el7.x86_64.rpm
Percona-Server-shared-57-5.7.31-34.1.el7.x86_64.rpm
Percona-Server-shared-compat-57-5.7.31-34.1.el7.x86_64.rpm
Percona-Server-test-57-5.7.31-34.1.el7.x86_64.rpm
Percona-Server-tokudb-57-5.7.31-34.1.el7.x86_64.rpm

  3. Now you can install Percona Server for MySQL 5.7 by running:

    rpm -ivh Percona-Server-server-57-5.7.31-34.1.el7.x86_64.rpm \
Percona-Server-client-57-5.7.31-34.1.el7.x86_64.rpm \
Percona-Server-shared-57-5.7.31-34.1.el7.x86_64.rpm

This will install only packages required to run the Percona Server for MySQL 5.7.

Optionally, you can install either the TokuDB storage engine, adding Percona-Server-tokudb-57-5.7.31-34.1.el7.x86_64.rpm or the MyRocks storage engine, adding Percona-Server-rocksdb-57-5.7.31-34.1.el7.x86_64.rpm to the install command.

You can find more information on how to install and enable the TokuDB storage in the TokuDB Installation guide.

You can find more information on how to install and enable the MyRocks storage engine in the Percona MyRocks Installation Guide guide.

To install all the packages (for debugging, testing, etc.) you should run:

$ rpm -ivh *.rpm

Note

When installing packages manually like this, you’ll need to make sure to resolve all the dependencies and install missing packages yourself.

The following table lists the default locations for files:

Files Location
mysqld server /usr/bin
Configuration /etc/my.cnf
Data directory /var/lib/mysql
Logs /var/log/mysqld.log

You can use the following command to locate the Data directory:

grep datadir /etc/my.cnf

datadir=/var/lib/mysql

Running Percona Server for MySQL

  1. Starting the service

    Percona Server for MySQL does not start automatically on RHEL and CentOS after the installation. You should start the server by running:

    service mysql start

  2. Confirming that service is running

    You can check the service status by running:

    service mysql status

  3. Stopping the service

    You can stop the service by running:

    service mysql stop

  4. Restarting the service

    You can restart the service by running:

    service mysql restart

Note

RHEL 7 and CentOS 7 come with systemd as the default system and service manager so you can invoke all the above commands with sytemctl instead of service. Currently both are supported.

Uninstalling Percona Server for MySQL

To completely uninstall Percona Server for MySQL you’ll need to remove all the installed packages and data files.

  1. Stop the Percona Server for MySQL service

    service mysql stop

  2. Remove the packages

    yum remove Percona-Server*

  3. Remove the data and configuration files

    rm -rf /var/lib/mysql
rm -f /etc/my.cnf

Warning

This will remove all the packages and delete all the data files (databases, tables, logs, etc.), you might want to take a backup before doing this in case you need the data.
