title: MariaDB service fails immediately after installation - CentOS7
body: <p>MariaDB service could not start after installation, fresh CentOS7 install with no Apache or PHP yet. Though it has Webmin panel installed but nothing other than that.</p>
  
  <p>The error message that I am getting is as following:</p>
  
  <blockquote>
    <p>Job for mariadb.service failed because the control process exited with
    error code. See "systemctl status mariadb.service" and "journalctl
    -xe" for details.</p>
