How to Control systemd Services on a Remote Linux Server

Updated: 28 September 2026 · Applies to: systemd 252 to 259 on AlmaLinux and Rocky Linux 9 and 10, RHEL 9 and 10, Ubuntu 24.04 and 26.04, Debian 13

systemctl can manage services on another server directly, over SSH, without logging in to it first. This is handy when you look after several servers: check a service, restart it or list failures from your own machine.

Before you start

• Both machines run systemd, and you can log in to the remote server with SSH. Key-based login is best, so no password prompts get in the way.
• Controlling services needs root on the remote side, so connect as root or as a user with the right permissions.

Use -H (--host)

systemctl -H root@203.0.113.10 status nginx
systemctl -H root@203.0.113.10 restart nginx
systemctl -H root@203.0.113.10 --failed
systemctl -H root@203.0.113.10 list-units --type=service --state=running

If SSH listens on another port, add it after a colon: -H root@203.0.113.10:2222. Put IPv6 addresses in brackets. The command runs on the remote server and prints the result locally.

The simple alternative: ssh with a command

ssh root@203.0.113.10 'systemctl restart nginx && systemctl is-active nginx'
ssh root@203.0.113.10 'journalctl -u nginx -n 30 --no-pager'

This works for any command, including journalctl for the service's logs.

Many servers at once

A short loop checks the same service everywhere:

for h in web1 web2 db1; do
  echo "$h: $(ssh root@$h systemctl is-active nginx)"
done

For regular work across many servers, a configuration tool such as Ansible is the better choice, for example ansible webservers -b -m ansible.builtin.systemd -a "name=nginx state=restarted".

Common problems

• "Failed to connect to bus" or the command hangs: SSH login failed. Test with ssh root@203.0.113.10 true first, and set up SSH keys.
• "Access denied": the remote user has no right to control services. Connect as root, or use ssh user@host sudo systemctl ....
• A different port or key: put them in ~/.ssh/config under a host alias; systemctl -H uses that file too.

Official documentation: systemctl (option --host).
