Installing Percona Server on Red Hat Enterprise Linux and CentOS

Installing Percona Server on Red Hat Enterprise Linux and CentOS

Ready-to-use packages are available from the Percona Server 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:

  • RHEL 6 (Current Stable) [1]
  • RHEL 7
  • RHEL 8
  • Amazon Linux AMI (works the same as CentOS 6)

Note

We support red Hat Enterprise Linux (RHEL) and the derivatives: CentOS, Oracle Enterprises Linux, and Amazon Linux for the selected version.

The CentOS repositories should work well with Red Hat Enterprise Linux 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CentOS 6 offers an outdated version of the curl library required by the keyring Vault plugin of Percona Server. 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. The current status is CLOSED WONTFIX.

If you intend to use the keyring Vault plugin of Percona Server, 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 will use this version.

Supported Platforms:

  • x86
  • x86_64 (also known as amd64)

What’s in each RPM package?

Each of the Percona Server 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.

Installing Percona Server from Percona yum repository

  1. Install the Percona repository

A Percona Server installation or upgrade, by default, creates the mysqld.cnf file. This file is defined as the default configuration and located in the /etc/percona-server.conf.d directory. The directory is created if that directory does not exist.

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

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

Output example

Retrieving https://repo.percona.com/yum/percona-release-latest.noarch.rpm
Preparing...                ########################################### [100%]
1:percona-release        ########################################### [100%]

To install Percona Server 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-56-5.6.42-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      5.7.10-3.1.el7                 @percona-release-x86_64
Percona-Server-client-57.x86_64         5.7.10-3.1.el7                 @percona-release-x86_64
Percona-Server-devel-57.x86_64          5.7.10-3.1.el7                 @percona-release-x86_64
Percona-Server-server-57.x86_64         5.7.10-3.1.el7                 @percona-release-x86_64
Percona-Server-shared-57.x86_64         5.7.10-3.1.el7                 @percona-release-x86_64
Percona-Server-shared-compat-57.x86_64  5.7.10-3.1.el7                 @percona-release-x86_64
Percona-Server-test-57.x86_64           5.7.10-3.1.el7                 @percona-release-x86_64
Percona-Server-tokudb-57.x86_64         5.7.10-3.1.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 by running:

    yum install Percona-Server-server-57

Note

Percona Server 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 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 5.7.10-3 release packages for CentOS 7:

    $ wget https://www.percona.com/downloads/Percona-Server-5.7/Percona-Server-5.7.10-3/binary/redhat/7/x86_64/Percona-Server-5.7.10-3-r63dafaf-el7-x86_64-bundle.tar

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

    $ tar xvf Percona-Server-5.7.10-3-r63dafaf-el7-x86_64-bundle.tar

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

    $ ls *.rpm

Percona-Server-57-debuginfo-5.7.10-3.1.el7.x86_64.rpm
Percona-Server-client-57-5.7.10-3.1.el7.x86_64.rpm
Percona-Server-devel-57-5.7.10-3.1.el7.x86_64.rpm
Percona-Server-server-57-5.7.10-3.1.el7.x86_64.rpm
Percona-Server-shared-57-5.7.10-3.1.el7.x86_64.rpm
Percona-Server-shared-compat-57-5.7.10-3.1.el7.x86_64.rpm
Percona-Server-test-57-5.7.10-3.1.el7.x86_64.rpm
Percona-Server-tokudb-57-5.7.10-3.1.el7.x86_64.rpm

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

    rpm -ivh Percona-Server-server-57-5.7.10-3.1.el7.x86_64.rpm \
Percona-Server-client-57-5.7.10-3.1.el7.x86_64.rpm \
Percona-Server-shared-57-5.7.10-3.1.el7.x86_64.rpm

This will install only packages required to run the Percona Server 5.7. Optionally you can install TokuDB storage engine by adding the Percona-Server-tokudb-57-5.7.10-3.1.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:

$ 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

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

  1. Starting the service

    Percona Server isn’t started automatically on RHEL and CentOS after it gets installed. You should start it 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

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

  1. Stop the Percona Server 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.

Footnotes

[1]“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 Percona Server builds 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 or prior. For any officially unsupported system, src.rpm packages may be used to rebuild Percona Server for any environment. Please contact our support service if you require further information on this.
