Put this in  etc init   Use  etc systemd in Ubuntu 15 x   mystartupscript conf  start on runlevel  2345  stop on runlevel   2345   exec  path to script py   By placing this conf file there you hook into ubuntu s upstart service that runs services on startup   manual starting stopping is done with sudo service mystartupscript start and sudo service mystartupscript stop
