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
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.

Supported Platforms:

x86_64 (also known as amd64)

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¶

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

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

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%]

Enable the repository:
```
$ sudo percona-release setup ps80
```
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¶

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
```

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

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.

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
```
Confirming that service is running

You can check the service status by running:
```
$ sudo service mysql status
```
Stopping the service

You can stop the service by running:
```
$ sudo service mysql stop
```
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.

Stop the Percona Server for MySQL service: service mysql stop
Remove the packages:
```
$ sudo yum remove percona-server*
```

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.
