Success with start-stop-daemon and mono-service2?

Question

Has anyone had any success using start-stop-daemon and mono-service2 together? I\'ve been fighting this for a few days now and have gotten various bits to work, but have ha

Answer 1

We had a lot of issues with mono-service and ended up implementing our own "service" code in our app. Nothing hard, just grabbing some signals:

UnixSignal intr = new UnixSignal (Signum.SIGINT);
UnixSignal term = new UnixSignal (Signum.SIGTERM);
UnixSignal hup = new UnixSignal (Signum.SIGHUP);
UnixSignal usr2 = new UnixSignal (Signum.SIGUSR2);

UnixSignal[] signals = new UnixSignal[] { intr, term, hup, usr2 };

for (bool running = true; running; )
{
    int idx = UnixSignal.WaitAny(signals);

    if (idx < 0 || idx >= signals.Length) continue;

    log.Debug("daemon: received signal " + signals[idx].Signum.ToString());

    if ((intr.IsSet || term.IsSet)) 
    {
        intr.Reset ();
        term.Reset ();

        log.Debug("daemon: stopping...");

        running = false;
    }
    else if (hup.IsSet)
    {
        // Ignore. Could be used to reload configuration.
        hup.Reset();
    }
    else if (usr2.IsSet)
    {
        usr2.Reset();
        // do something
    }
}

Answer 2

I got this script working with a couple of minor changes:

• A pidfile in /var/run only works if you run as root - if you try to run the script without sudo, mono-service will fail silently.

• Use --pidfile instead of --name to find the service to stop.

Answer 3

do_stop()
{ 

test -f $PIDFILE && kill `cat $PIDFILE` && return 2

 start-stop-daemon --stop --quiet --verbose --oknodo --retry=0/30/KILL/5\ 

--exec mono-service2

 [ "$?" = 2 ] && return 2

 # Many daemons don't delete their pidfiles when they exit.

 rm -f $PIDFILE

 return "$RETVAL"

}

So it works, I think it just because you can't stop a process by the command "start-stop-daemon" i'm learning to use mono now,your invitation help me very much.thank you. my english is poor,forgive my half-baked english.

I know this question is old but there are no accepted answers. I tinkered around with this for awhile too and came up with a daemon script which worked like a charm for me. I blogged about it here: http://www.geekytidbits.com/start-stop-daemon-with-mono-service2/
