[ale] Need help with running a process from systemd or ???

[Jim Lynch]

The situation is that I have a perl script that needs to stay running as 
long as the system is up.  I also need to be able to restart the script 
at will.  I'm currently running it in an infinite loop shell script and 
it works, but I'm starting it manually.  I think I have figured out how 
to run it via systemd using the Restart=always option, but the 
application that needs to restart it isn't running as root.  Currently 
it's restarted by sending a KILL to the pid that was stored in the 
script.  The killing program is a web page running PHP.

I'm running Ubuntu 16.04 server.

I don't see a way to run the serviced script as another user.  I suppose 
I could configure sudo to run kill without a password.

Anyway I'm looking for advice as to the best way to handle this 
situation.  Simpler is better.

Thanks,

Jim.
