Autostart on Debian using init.d script

The instructions for Ubuntu/Debian did not seem to work for Debian very well, and the pid got lost whenever Sonarr was restarted via the web-ui, so I've included a working script here init.d script here. You'll need to have already created an nzbdrone user.

Create and edit the nzbdrone init.d script

sudo vim /etc/init.d/nzbdrone

Paste the following, changing applicable variables

#! /bin/sh
### BEGIN INIT INFO
# Provides:          NzbDrone
# 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 Sonarr
# Description:       starts instance of Sonarr using start-stop-daemon
### END INIT INFO

esac

exit 0

Make it executable

sudo chmod +x /etc/init.d/nzbdrone

Update rc.d

sudo update-rc.d nzbdrone defaults

Start Sonarr

sudo service nzbdrone start
