title: Restart Tomcat Service on AWS EC2 instance, on a schedule
body: <p>I have an instance on Tomcat running on EC2.  Based on some resourcing reasons that I don't want to get into, I'd like it to restart each evening at 11:00pm.  I'm not interested in reloading or stopping the applications context as the PermGen space gets crowded until eventually the box tips over and dies.</p>
  
  <p>So where on an aws linux instance do I specify <code>service tomcat7 restart</code> and give it a cron expression?</p>
