Running Percona Server

The default directory where Percona Server  stores data files is the /var/lib/mysql/. The main configuration file that will affect and handle the operation of the Percona Server  is the /etc/my.cnf. file

  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
  1. Confirming that service is running

You can check the service status by running:

service mysql status
  1. Stopping the service

You can stop the service by running:

service mysql stop
  1. 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.

  1. Stop the Percona Server service 
    service mysql stop
  1. Remove the packages 
    yum remove Percona-Server*
  1. Remove the data and configuration files 
    rm -rf /var/lib/mysql

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.
