init.d script startup problems

  • 772

I Have this init.d script which I am trying to get to startup with ubuntu however it wont run at startup. It does work when i type "sudo /etc/init.d/couchpotato start" though. Any ideas on how to get it starting at boot?

#! /bin/sh

### BEGIN INIT INFO

# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts instance of CouchPotato
# Description:       starts instance of CouchPotato using start-stop-daemon
### END INIT INFO

  1. You can try to run this in terminal:

    sudo chmod 755 /etc/init.d/couchpotato

    sudo update-rc.d couchpotato defaults

    ================================

    And when you want to disable it from running at startup:

    sudo update-rc.d -f couchpotato remove

    To find out more information do:

    man update-rc.d

    You might try to use the insserv command. From the "man insserv" command on a 10.10 installation, I can read: 

    insserv - Enable an installed system init script.

  3. I never could get the supplied init.d script to work. I could run it just fine, but init.d would start couchpotato, but I could never connect to it. I went ahead and created my own dirty script for it. This should work assuming you use the path ~/.couchpotato for your installdir.

    ### BEGIN INIT INFO
# Provides:          CouchPotato application instance
# Required-Start:    $local_fs $network $remote_fs
# Required-Stop:     $local_fs $network $remote_fs
# Should-Start:      $NetworkManager
# Should-Stop:       $NetworkManager
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts instance of CouchPotato
# Description:       starts instance of CouchPotato using start-stop-daemon

### END INIT INFO

USER="youruser"

case "$1" in

  start)
        echo "Starting $DESC"
        /home/micdawg/.couchpotato/CouchPotato.py &
        ;;
  stop)
        echo "Stopping $DESC" 
        PID=`ps -ef | grep CouchPotato.py | grep -v grep | awk '{print $2}'`
        kill -9 $PID 
        ;;

  restart|force-reload)
        echo "Restarting $DESC"
        PID=`ps -ef | grep CouchPotato.py | grep -v grep | awk '{print $2}'`
        kill -9 $PID 
        sleep 15
        /home/micdawg/.couchpotato/CouchPotato.py &
        ;;
  *)
        N=/etc/init.d/$NAME
        echo "Usage: $N {start|stop|restart|force-reload}" >&2
        exit 1
        ;;

  4. from the man: runlevel information in the init.d script LSB comment header is used (..) Such header is required to be present in init.d scripts. See the insserv( manual page for details about the LSB header format.

    Example:

    ### BEGIN INIT INFO
# Provides: apache2
# Required-Start: $local_fs $remote_fs $network $syslog
# Required-Stop: $local_fs $remote_fs $network $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# X-Interactive: true
# Short-Description: Start/stop apache2 web server
### END INIT INFO

  5. The accepted answer assumes that "upstart" is being used to start processes when the system boots. This is not always so. I am using Ubuntu 9.04 Minimal running on a virtual private server and this does not use upstart.

    In this case, in order for the system to notice and run the scripts in /etc/init.d you need to run update-rc.d which created symbolic links to your inet.d script in places where the system will look for instructions when it boots up.

    Something like this:

    update-rc.d couchpotato defaults 92

    The 92 is a sensible value for the priority, delaying the startup of your script until other important stuff is running.

    Here are more details about running update-rc.d

  6. If you are not getting any clue why your service is not getting started on boot. However it gets started perfectly fine when you try to start it manually with command service <your service> start. Then try redirecting standard output and error output to some file. Which may give you some clue why it is not getting started

    e.g. inside your script 

    case "$1" in
  start)
    echo "Starting Service "
    <your command to start the service > /tmp/bootservice.log 2>&1
    ;;
  stop)
    echo "Stopping Service "
    <your command to start the service > /tmp/bootservice.log 2>&1
    ;;
  *)
    echo "Usage: /etc/init.d/test {start|stop}"
    exit 1
    ;;
esac

exit 0
