<h1>Reboot MySQL Database Server</h1>
<p>If the MySQL Database crashes then you can run this script which will login to the server via SSH and execute the restart commands to start the database server.</p>
<p>If this does not resolve the issue then please contact Jason Davis - jason.davis.fl@gmail.com</p>
