Running a script as a daemon at boot time

Wed May 29 18:09:53 EDT 2002

I've a script which in part serves as an HTTP server.  I can run this as a background process when logged on as myself.  I need to find a way to have the script run as a daemon at boot time.  I have written a script for /etc.rc.d/init.d and it responds well to start/stop commands.  However, when a GET request arrives at the server, the process dies without generating an error (at least that I've been able to trap.)  The do_GET is as follows:

    def do_GET(self):

        self.ServerLog('Requested GET')

        htmlpage = '<html><head>'
        htmlpage = htmlpage + '<title>Green Bar Queue Processor</title>'
        htmlpage = htmlpage + '</hted><body>'
        htmlpage = htmlpage + '<p style="font: Arial;">Green Bar Queue Processor - ' + time.strftime("%a, %d %b %Y %H:%M:%S", time.localtime(time.time())) + '<hr></p>'
        htmlpage = htmlpage + '</body></html>'

        notfound = 'File not found.'

        if self.path == "/":

            self.ServerLog('Mark 1') # This line gets logged...

            self.send_response(200)

            self.ServerLog('Mark 1') # This line DOES NOT get logged...

            self.send_header("Content-type", "text/html")
            self.end_headers()
            self.wfile.write(htmlpage)
        else:
            self.send_error(404, notfound)

When the background process is initiated from the command line, this error does not occur and the daemon performs as needed.  Why would this fail as a boot (inet.d) initiated script and not from the command line?  The startup script is as follows:

---- start gbqp---

#!/bin/sh
#
# Startup script for GBQueueProcessor.py 
#
# processname: python
# pidfile: /var/run/gbqp.pid
# config: GBQueueProcessor.conf

# Source function library.
. /etc/rc.d/init.d/functions

[ -f /usr/local/bin/GBQueueProcessor.py ] || exit 0

RETVAL=0

start() {
    echo -n "Starting gbqpd: "
    daemon /usr/local/bin/gbqpd
    echo
    touch /var/lock/subsys/gbqpd
    return $RETVAL
}

stop() {
    echo -n "Shutting down gbqpd: "
    GBQPDPID=
    GBQPDPID=$(cat /var/run/gbqpd.pid)
     kill $GBQPDPID
    echo
    rm -f /var/lock/subsys/gbqpd /var/run/gbqpd.pid
    return $RETVAL
}

# See how we were called.
case "$1" in
  start)
    start
    ;;
  stop)
    stop
    ;;
  status)
    GBQPDPID=
    GBQPDPID=$(cat /var/run/gbqpd.pid)
   echo -n "Checking for gbqpd, PID is : " $GBQPDPID
   echo 
    ;;
  restart)
     stop
     start
    ;;
  *)
    echo "Usage: $0 {start | stop | restart | status}"
    exit 1
esac

exit 0

---- end gbqp---

---- start gbqpd---

#!/bin/sh

exec python /usr/local/bin/GBQueueProcessor.py

---- end gbqpd---
