Controling systemd Services on Remote Linux Server (original) (raw)

Last Updated : 18 May, 2026

systemd is a modern system and service manager for Linux that handles service startup, process tracking, and resource management. It replaces traditional SysVinit scripts with a unified, dependency-based approach to controlling system services and resources.

• Provides parallelized system startup for faster boot times.
• Supports on-demand activation of daemons and background services.
• Tracks and manages processes using Linux control groups (cgroups).
• Maintains mount and automount points.
• Uses unit files to define and control services, sockets, mounts, and other system resources.

Controlling systemd Services on a Remote Linux Server

systemd allows administrators to manage services on a remote Linux server using SSH-based connections. Follow the steps below to configure and control systemd services remotely.

Step 1: Create a dedicated systemd management user on the remote server

Log in to the remote server and create a user that will be used to manage systemd services:

**Command:

sudo useradd --create-home systemd-manager

• (Optional but recommended) Set a password or configure SSH key-based authentication for this user.

Output

Step 2: Prepare SSH key-based authentication

Create the .ssh directory for the new user and set proper permissions:

sudo mkdir /home/systemd-manager/.ssh
sudo chmod 700 /home/systemd-manager/.ssh
sudo chown systemd-manager:systemd-manager /home/systemd-manager/.ssh

**Copy your public SSH key into the following file on the remote server:

/home/systemd-manager/.ssh/authorized_keys

**Set correct permissions:

sudo chmod 600 /home/systemd-manager/.ssh/authorized_keys
sudo chown systemd-manager:systemd-manager /home/systemd-manager/.ssh/authorized_keys

systemd relies on PolicyKit (polkit) to authorize privileged operations. Ensure polkit is installed on the remote server:

**Command:

sudo apt install policykit-1

• To allow the systemd-manager user to manage systemd services, appropriate polkit rules must be configured. This step is required for starting, stopping, or reloading services remotely.

Output

Step 4: Remotely manage systemd services

Once SSH access and authorization are configured, use the systemctl command with the --host (or -H) option to manage services on the remote server.

**For example, to check the status of the nginx service:

systemctl --host systemd-manager@server.example.org status nginx

Output

Step 5: Perform additional systemd operations

You can perform other systemd actions remotely in the same way. For example, to reload systemd configuration files on the remote host:

**Command:

systemctl --host systemd-manager@server.example.org daemon-reload

Output

Step 6: End the Remote Session

Each systemctl --host command uses a separate SSH connection. Once your commands are complete, simply exit the terminal or press Ctrl+C if a command is running interactively.

**For more information, consult the manual page:

man systemctl
