Correct way of running UMS as daemon?

Post by bodom » Mon Oct 08, 2018 5:09 am

Hi there,

I am running UMS as daemon using screen.

Code: Select all

sudo -u ums screen -d -m -S UMS /opt/ums/UMS.sh
It works, but i bet that's not the correct way to do this. Do you have any suggestion for a nice systemd integration?

I guess you are running Linux.
I use a startup script which is the correct way to go I believe.

I don't use system but I believe the commands might be:
systemctl enable [email protected]
systemctl start [email protected]
AND THEN TO STOP UMS
systemctl stop [email protected]

Alternatively you could see if a bash script works.
This is mine which you could modify (depending on file locations) and I use openrc:

#!/bin/bash
#

# Required-Stop: $local_fs $remote_fs $network

test -x $DAEMON || exit 1
