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.

Supported Releases:

  • CentOS 6 and RHEL 6 (Current Stable)
  • CentOS 7 and RHEL 7
  • RHEL 8
  • Amazon Linux AMI (works the same as CentOS 6)
  • Amazon Linux 2

Important

“Current Stable”: We support only the current stable RHEL6/CentOS6 release, because there is no official (i.e. RedHat provided) method to support or download the latest OpenSSL on RHEL/CentOS versions prior to 6.5. Similarly, and also as a result thereof, there is no official Percona way to support the latest builds of Percona Server for MySQL on RHEL/CentOS versions prior to 6.5. Additionally, many users will need to upgrade to OpenSSL 1.0.1g or later (due to the Heartbleed vulnerability), and this OpenSSL version is not available for download from any official RHEL/Centos repository for versions 6.4 and prior. For any officially unsupported system, src.rpm packages may be used to rebuild Percona Server for MySQL for any environment. Please contact our support service if you require further information on this.

The CentOS repositories should work well with Red Hat Enterprise Linux too, provided that yum is installed on the server.

Important

CentOS 6 offers an outdated version of the curl library required by the keyring Vault plugin of Percona Server for MySQL. The version of the curl library in CentOS 6, which depends on the nss library, is known to create memory corruption issues. This bug is registered in Red Hat Bugzilla. Its current status is CLOSED WONTFIX.

If you intend to use the keyring Vault plugin of Percona Server for MySQL make sure that you use the latest version of the curl library. We recommend that you build it from source configuring with ssl but without nss:

$ ./configuration --with-ssl --without-nss --prefix=<INSTALATION DIRECTORY>

As soon as you install curl, make sure that Percona Server for MySQL will use this version.

What’s in each RPM package?

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

Package Contains
percona-server-server The server itself (the mysqld binary)
percona-server-debuginfo Debug symbols for the server
percona-server-client The command line client
percona-server-devel the header files needed to compile software using the client library.
percona-server-shared The client shared library.
percona-server-shared-compat Shared libraries for software compiled against old versions of the client library. The following libraries are included in this package: libmysqlclient.so.12, libmysqlclient.so.14, libmysqlclient.so.15, libmysqlclient.so.16, and libmysqlclient.so.18.
percona-server-test package includes the test suite for Percona Server for MySQL.

Installing Percona Server for MySQL from Percona yum repository

Please add sudo to percona-release setup and yum install commands

Run the following commands as root or by using the sudo command

  1. Install the Percona repository

    You can install Percona yum repository by running the following command as a root user or with sudo:

    $ sudo yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm

    You should see some output such as the following:

    Retrieving http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-latest.noarch.rpm
Preparing...                ########################################### [100%]
1:percona-release        ########################################### [100%]

  2. Enable the repository:

    $ sudo percona-release setup ps80

  3. Install the packages

    You can now install Percona Server for MySQL by running:

    $ sudo yum install percona-server-server

Note

Percona Server for MySQL 8.0 comes with the TokuDB storage engine and MyRocks storage engines. These storage engines are installed as plugins. You can find more information on how to install and enable the TokuDB storage in the TokuDB Installation guide. More information about how to install MyRocks can be found in the section Percona MyRocks 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 8.0.13-3 release packages for CentOS 7:

    $ wget https://www.percona.com/downloads/Percona-Server-8.0/Percona-Server-8.0.13-3/binary/redhat/7/x86_64/Percona-Server-8.0.13-3-r63dafaf-el7-x86_64-bundle.tar

  2. You should then unpack the bundle to get the packages: tar xvf Percona-Server-8.0.13-3-r63dafaf-el7-x86_64-bundle.tar

    After you unpack the bundle you should see the following packages when running ls *.rpm:

    Output

    percona-server-80-debuginfo-8.0.13-3.el7.x86_64.rpm
percona-server-client-80-8.0.13-3.el7.x86_64.rpm
percona-server-devel-80-8.0.13-3.el7.x86_64.rpm
percona-server-server-80-8.0.13-3.el7.x86_64.rpm
percona-server-shared-80-8.0.13-3.el7.x86_64.rpm
percona-server-shared-compat-80-8.0.13-3.el7.x86_64.rpm
percona-server-test-80-8.0.13-3.el7.x86_64.rpm
percona-server-tokudb-80-8.0.13-3.el7.x86_64.rpm

Note

For an RHEL 8 package installation, Percona Server requires the mysql module to be disabled.

$ sudo yum module disable mysql

  1. Now you can install Percona Server for MySQL 8.0 by running:

    $ sudo rpm -ivh percona-server-server-80-8.0.13-3.el7.x86_64.rpm \
percona-server-client-80-8.0.13-3.el7.x86_64.rpm \
percona-server-shared-80-8.0.13-3.el7.x86_64.rpm

This will install only packages required to run the Percona Server for MySQL 8.0. Optionally you can install TokuDB storage engine by adding the percona-server-tokudb-80-8.0.13-3.el7.x86_64.rpm to the command above. You can find more information on how to install and enable the TokuDB storage in the TokuDB Installation guide.

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

$ sudo 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.

Running Percona Server for MySQL

Percona Server for MySQL stores the data files in /var/lib/mysql/ by default. You can find the configuration file that is used to manage Percona Server for MySQL in /etc/my.cnf.

  1. Starting the service

    Percona Server for MySQL is not started automatically on RHEL and CentOS after it gets installed. You should start it by running:

    $ sudo service mysql start

  2. Confirming that service is running

    You can check the service status by running:

    $ sudo service mysql status

  3. Stopping the service

    You can stop the service by running:

    $ sudo service mysql stop

  4. Restarting the service

    You can restart the service by running:

    $ sudo 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:

    $ sudo 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.
