title: MySQL not running on Linux machine
body: <p>I tried everything and I am still unable to start the MySQL service. The error is as below:</p>
  
  <pre><code>[root@localhost ~]# service mysql.server start Starting MySQL..... 
  ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).
  [root@localhost ~]# service mysql start Starting MySQL....
  ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).
  </code></pre>
  
  <p>Things I tried:</p>
  
  <p>Removing the .err file and restarting, no use. Creating a .sock file and a .pid file as the above error mentions, still no use. Almost tried all the steps in most of the forums, still nothing.</p>
  
  <p>I tried all the config files, nothing seems to resolve my issue.</p>
