Step 1: Install the Percona repository

We can install Percona yum repository by running the following command.

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

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

Test the repository with the below command.

# yum list | grep percona

Step 2: Install the Percona Server

Install the Percona Server by running below command.

# yum install Percona-Server-server-57

Step 3: Run 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.

Start the Percona service with the below command:

# systemctl start mysql

Next, check the service status by running below command:

# systemctl status mysql

Stop the service by running below command:

# systemctl stop mysql

Restart the service by running by running below command:

# systemctl restart mysql

Once, service is started check the mysql root password by running below command:

# grep 'temporary password' /var/log/mysqld.log

Next reset the password to the one of your choice by logging into the mysql console.

# mysql -u root –p
# ALTER USER 'root'@'localhost' IDENTIFIED BY 'StrongPassword';
# flush privileges;
