Cron job to restart Tomcat when it crashes

[Michael Wood]

My Lucee server is crashing because I haven't quite figured out how to configure it properly. As a temporary solution I have written a bash script to run as a cron job every 5 minutes. This should check if TC is running and accessible and restart Lucee/TC if not. I would appreciate constructive comments or improvements. I have the website running on port 80 on Tomcat (no Apache). This is running as a system cron.

#!/bin/bash

if sudo netstat -tulpen | grep ":80 " > /dev/null 2>&1  &&  ps -ef | grep tomcat | grep java > /dev/null 2>&1 

then

        echo "Tomcat Running" > /dev/null

else

        echo "Tomcat Stopped" > /dev/null

sudo /opt/lucee/lucee_ctl restart

fi

Installing Fusion Reactor (http://www.fusion-reactor.com/ ) on this server would help you a great deal and it can handle the restarts after crashes.  It will also give you a ton of useful information that will help you in tuning your server, along with identifying bottlenecks in your application.
