Running control scripts as daemons

rumal · 06-06-2011, 08:57 AM

Hello, I'm working with debian squeeze in an embedded system that have an ARMv5 on it.

I need to maintain active several programs, they always have to be running, and if they die, no matter what happend, they must be launched again.

Now I have one script for each program that basically do this:

Code:

#!/bin/bash

cd /opt/
java -jar myProgram.jar

exit 0

And then I call all the script from etc/inittab whith respawn. That work fine for me, but I think that there is a better way to do this...

This solution does what you said you need, and it uses few
resources. In what way do you want to improve on this?

I'd like to do in a more standard or robust way.

That is the standard way. And it's very robust.

The other common way to do this is to have a process running that
just checks to see if it needs to restart the original process.
The advantage of this method is that it gives you the option to
do other things such as send email or submit a log entry. This
method is less robust, but can be customized as needed.
