There is a whole new world called systemd to start programs. Until you tame it you are going to struggle. I struggled to start mythtv. I post the full file as there are some gotchas ------------------------------------------------------------------- sandypit:~ # cat mythbackend.service # Do not edit this file, it will be replaced on update # If you need to make modifications to this unit file first make a copy in # /etc/systemd/system # This file is part of the packaging of MythTV # # MythTV is free software; view http://www.mythtv.org for more information. # # It is sometimes necessary to wait for a capture device to finish (hot)plug # initialization before the backend starts. If this is necessary, # create a Wants and After entry for all the capture devices that # one wishes to wait to be created before the backend starts using the systemd # device name mangling names (/dev/some/thing turns # into dev-some-thing.device). These normally should be udev persistent # filename rules to avoid confusion. # See the MythTV wiki for udev persistent filename # discussions found at: # http://www.mythtv.org/wiki/Device_Filenames_and_udev # # In order to insure that systemd will create a device unit for the # capture device, one must insure that udev will have the tag "systemd" # (i.e. add TAG+="systemd" to the udev rule). # # The MythTV package ships with a default udev rule file located in: # /lib/udev/rules.d/99-mythbackend.rules [Unit] Description=MythTV backend service After=network.target mysqld.service # Uncomment the following line if you will be using the mythweb plugin on the # same system as mythbackend. #Wants=httpd.service [Service] # You have 2 choices for 'Type': simple or forking # These require ExecStart lines which are NOT interchangeable. # Type=simple is recommended. # If using 'Type=simple' # 1) you cannot have --daemon in the command line # If using 'Type=forking' # 1) you must have --daemon in the command line AND # 2) you must have --pidfile /somewhere in the command line AND # 3) you must have a line PIDFILE=/somewhere in the [service] stanza # this lets systemd know how to find the forked process PID, # otherwise it presumes the starting process will be the remaining process # (cf. with the mysqld_safe process which starts mysqld and then disappears). # Specifying a pidfile with Type simple does not cause any problems and # may help in debugging startup failures. #Type=forking Type=simple #jamEnvironment=MYTHCONFDIR=/etc/mythtv # Default setting assumes a system wide install.
