Systemd system and services manager can be controlled using the systemctl command line utility. It enables you to manage systemd locally or on a remote Linux machine over the SSH protocol.
In this short article, we will show you how to manage systemd system and service manager on a remote Linux machine over a SSH session.
Attention: We recommend using public/private key pairs for passwordless authentication for SSH, as opposed to passwords, and also employing additional methods to secure SSH service, as explained in these guides.

To connect to a remote server, run systemctl with the
-H flag as follows. In the command below, we are connecting to the remote server as the root user and status is a subcommand of systemctl utility used to view the status of the httpd service on centos.temint.lan (remote Linux server).
$ systemctl --host [email protected] status httpd.service OR $ systemctl -H [email protected] status httpd.service
Similarly, you can also start, stop or restart remote systemd service as shown.
$ systemctl --host [email protected] start httpd.service $ systemctl --host [email protected] stop httpd.service $ systemctl --host [email protected] restart httpd.service
