Running Systemd commands on remote host from your local host
While I was reading the pretty awesome Archlinux wiki for
something completely different, I found out that one can launch any systemctl
command to a remote host via the --host (or -H) flag.
So let say you want to check the cron process on a server named kitten:
1 2 3 4 5 6 7 8 9 |
$ systemctl -H root@kitten status cron
● cron.service - Regular background program processing daemon
Loaded: loaded (/lib/systemd/system/cron.service; enabled; vendor preset: enabled)
Active: active (running) since Sat 2018-07-28 11:36:37 CST; 2 months 25 days ago
Docs: man:cron(8)
Main PID: 1045
Tasks: 1 (limit: 4643)
CGroup: /system.slice/cron.service
└─1045 /usr/sbin/cron -f |
Nice right? Under the hood this use SSH so you must have access to the host.
And you can, of course, use any systemctl command, not just status ;)
