Set a Perl script as an unix service (start with system)

onlymed · 04-01-2009, 11:22 AM

Hello ,
I have a real probleme with my servers :
I have created a Client (script) <-> server (daemon) application (works fine) using SOAP::Lite

If the server is launched using the line command everything works well and the requests are received and the answers sent.

Once i try to set the server side as a real service using : /etc/init.d/ the server is not started at the start time.

And if i use the commande /etc/init.d/myservice start - to start it : the server starts , listens to requests but do nothing else .
however when i use netstat -a | grep myport i see that there are an established connexion between client and server .
i really don't know how to solve this probleme.

Another try was to set a cron task which will start the perl daemon:

cron starts a bash script (myTask.sh) which will see if the server is already on if no starts it (myServer.pl). (like a watchdog) and i got another problème myServer.pl is killed once the myTask.sh finish .
i tried with nohup nothing done . and is i use disown in the .sh file i got the error disown not found .

Thanks for help

Please elaborate on *what* you did there. Just putting a script
into that directory will NOT execute it on boot. You need to
have an appropriate symlink to it in one of the rc[23].d directories

Thanks for your replay :
i put a script in

Code:

/etc/init.d/

and also create links in rc2 ...

If i launch the created service manually :

Code:

/etc/init.d/myService start

the server starts, listen to requests, but didn't answer.

If i starts it using Perl PATH_SERVER/myServer.PL , it works fine
i really don't see where is the problem .

Thanks again for help .
