How to install MariaDB on ClearOS

MariaDB replaces MySQL in ClearOS 7.x (vs 6.x)

Install MariaDB

Via the web interface

  • Search for "Database" in the marketplace
  • Install

Via the command line

yum install app-mariadb


  • Visit https://example.org:81/app/mariadb
  • Start it (it will automatically restart on server reboot)
  • You'll need to set a root password
  • You will then have access to phpMyAdmin

To change setting for the PHP used by phpMyAdmin for MariaDB (ex.: upload size, or timeout) (but as of 2016-03-20, phpMyAdmin is broken by the upgrade to PHP 5.6) fixed

nano /usr/clearos/sandbox/etc/php.ini
service httpd restart
