{bb} Scripting BB startup/shutdown in Red Hat

[Shane Presley <shane.presley@gmail.com>]

Hello,

I created a service defintion for BB in RedHat, and used this startup script:

#!/bin/bash
#
# bb      This shell script takes care of starting and stopping
#             standalone BigBrother.
#
# chkconfig: - 89 16
# description: BigBrother is a network monitoring daemon
# processname: runbb.sh

start() {
        # Start daemons.

        su - bb -c "/usr/local/bb/bb/runbb.sh start"
        return $RETVAL
}

stop() {
        # Stop daemons.
        su - bb -c "/usr/local/bb/bb/runbb.sh stop"
        return $RETVAL
}

# See how we were called.
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart|reload)
        stop
        start
        RETVAL=$?
        ;;
  status)
        status $prog
        RETVAL=$?
        ;;
  *)
        echo $"Usage: $prog {start|stop|restart|reload|status}"
        exit 1
esac

exit $RETVAL




It works great to start the service (running as bb not root). 
However, when I try to use this script to stop the service, it doesn't
shut down cleanly:
service bb stop
Stopping Big Brother...
/usr/local/bb/bb/runbb.sh: line 145: kill: (12372) - Operation not permitted
/usr/local/bb/bb/runbb.sh: line 145: kill: (12235) - No such process
/usr/local/bb/bb/runbb.sh: line 145: kill: (12372) - Operation not permitted
/usr/local/bb/bb/runbb.sh: line 145: kill: (12373) - No such process
/usr/local/bb/bb/runbb.sh: line 145: kill: (12235) - No such process
/usr/local/bb/bb/runbb.sh: line 145: kill: (12372) - No such process


Specifically, it does kill all the BB processes, but it leaves BBPID,
so that BB thinks it is still running.  It also creates runbb.sh.12373
with this info:

cat runbb.sh.12373
12235 pts/1    S      0:00 /bin/sh /usr/local/bb/bb/runbb.sh start
12372 pts/1    S      0:00 su - bb -c /usr/local/bb/bb/runbb.sh stop
12373 pts/1    S      0:00 /bin/sh /usr/local/bb/bb/runbb.sh stop
12235 pts/1    S      0:00 /bin/sh /usr/local/bb/bb/runbb.sh start
12372 pts/1    S      0:00 su - bb -c /usr/local/bb/bb/runbb.sh stop
12373 pts/1    S      0:00 /bin/sh /usr/local/bb/bb/runbb.sh stop
12235 pts/1    S      0:00 /bin/sh /usr/local/bb/bb/runbb.sh start
12372 pts/1    S      0:00 su - bb -c /usr/local/bb/bb/runbb.sh stop
12373 pts/1    S      0:00 /bin/sh /usr/local/bb/bb/runbb.sh stop

So BB is really stopped, but if I try a bb start, it says that it's
already running. I have to wipe out BBPID to get it started again.  
Also, if I run runbb.sh stop manually, it works fine.  Its only in my
script that it fails.

Any idea where my problem might be?  Thanks,
Shane
