# This shell script will launch the 'Multi Relay Chat' python script. It is intended to be called #
|
||||
# via a forked systemd .service file. The script will check that mrc_client.py is not already #
|
||||
# running then will launch it. To avoid problems, it should be launched using the same user that #
|
||||
# owns the mystic install directory. If executing manually, use 'sudo -u username' or ensure you #
|
||||
# are logged into the terminal as the user that owns the mystic directory. In a systemd .service #
|
||||
# file, you should use the 'User=' option in the [Service] section. The script will exit with an #

#==================================================================================================
|

# This systemd service file can be used to start and stop the 'Multi Relay Chat' python script as #
|
||||
# a proper service module. In order for it to work correctly, it must be set to 'Type=forking'. #
|
||||
# As a forking service, it will decide if start/stop was a failure based on the returned error #
|
||||
# code. A return of 0 will be considered success, and a return of 1 will be a failure. The MRC #
|
||||
# python script should ideally be launched as the same user who owns the mystic directories. To #
|
||||
# do this, be sure to uncomment and set the 'User=' option in the [Service] section below. If you #
|
||||
# don't, the script will be executed as root, which may have security implications. This file is #
|
||||
# indended to work with Debian, Ubuntu, Raspbian and other debian based distributions, but may #
|
||||
# work with others as well. #
|
||||
# #
|
||||
# Be sure to set the location of your mrc-start.sh and mrc-stop.sh scripts in the [Service] #
|
||||
# section below, and to optionally set your user as described above. #
