So I am relatively new to Centos, version 6.2. I have a service that needs to be mnonitored as a cron job, and if it stops needs to be restarted. I have a few ideas on how to monitor it, but when it comes to getting it restarted thats when I get stuck. I also know the PiD of the service I want to monitor.

You can use supervise for this: http://cr.yp.to/daemontools/supervise.html

Put it in your crontab to launch on system start:

@reboot supervise foo

  • Sorry I suppose I should have clarified. I am required to only do it through bash scripting. So no convenient or easy to use tools, otherwise I would be using daemon tools – Dr.Bradley Apr 20 '18 at 14:32
  • Well then it's time to start writing code. We won't do it for you. – John Zwinck Apr 21 '18 at 00:36
