I run my script(socket) as daemon with init-script :

   #!/bin/bash



### BEGIN INIT INFO
 # Provides:          sock_serv
 # Required-Start:    $local_fs $syslog $remote_fs
 # Required-Stop:     $local_fs $syslog $remote_fs
 # Default-Start:     2 3 4 5
 # Default-Stop:      0 1 6
 # Short-Description: sock_servservice
 # Description:       Run sock_serv service
 ### END INIT INFO

 # Carry out specific functions when asked to by the system
 case "$1" in
   start)
     echo "Starting sock_serv..."
     if sudo -u root bash -c 'cd ~/mypath/ && python3 sock_serv.py &> /dev/null &' ; then
       echo "OK"
     else
       echo "Error: can't start "
     fi
   ;;
stop)
   echo "Stopping sock_serv..."
   if sudo -u root bash -c 'cd ~/mypath/ && python3 stop_sock_serv.py &>/dev/null &'; then
   # sleep 2
      echo "OK"
   else
      echo "Error: can't stop "
   fi
   ;;
   *)
echo "Usage: /etc/init.d/sock_serv {start|stop}"
exit 1
;;
esac

I use in sock_serv loop wiht Module Select to receive Message from different client.

I can run my sock_serv, but after hours the sock_serv listen to any port( is stoped)

when I run service sock_serv status bevor and after sock_serv is stoped I get :

     sock_serv.service - LSB: sock_serv service
     Loaded: loaded (/etc/init.d/sock_serv; generated)

  • I would try to figure out why sock_serv.py is exiting. Commented Oct 13, 2019 at 15:30
  • If that's not an option, you automatically restart it when it crashes. One way is to use systemd with Restart=on-failure. Commented Oct 13, 2019 at 15:32
  • thanks for your answer,. Where I put this line Restart=on-failure ? Commented Oct 13, 2019 at 16:07
