My configs and setup to get NUT running on my ubuntu desktop with an Mecer ME-2000-VU.
This guide previously contained instructions on setting up an Eaton 5E. Those can be found in the eaton-5e tag.
upssched-cmd replaces the pre-installed file. This will log a message to syslog when ups goes on battery or comes online. Also has a upsonbatt command to shutdown the NUT master.
Mostly default configuration for UPS in standalone mode.
upsmon.conf calls /bin/upssched as a NOTIFYCMD. This ensures the configutaion in upssched.conf is executed.
The ups beeper does not stay off. Appears to turn back on after losing power or turning itself off. This is a simple cron that will check the current status and if the beeper is not disabled, disable it. Requires a few variables to be configured.
To install everything in the correct directories and restart all services:
make redeploy-all
The upssched command is run as the nut user. In order to shutdown the host system, the nut user needs permissions to do so. Add the following to /etc/sudoers
# All nut group ability to shutdown server
%nut ALL=NOPASSWD: /sbin/shutdown
upsc <upsname>
→ upsc ups
