Wireguard Basic Commands

he wg-quick tool is a simple way to bring the WireGuard interface up and down. That control is also exposed via a systemd service, which means the standard systemctl tool can be used.

Probably the greatest benefit of this is that it gives you the ability to configure the interface to be brought up automatically on system boot. For example, to configure the wg0 interface to be brought up at boot, run the following command:

$ sudo systemctl enable wg-quick@wg0 The name of the systemd service follows the WireGuard interface name, and multiple such services can be enabled/started at the same time. You can also use the systemctl status, start, stop, reload and restart commands to control the WireGuard interface and query its status:

$ sudo systemctl reload wg-quick@wg0 The reload action does exactly what we expect: it reloads the configuration of the interface without disrupting existing WireGuard tunnels. To add or remove peers, reload is sufficient, but if wg-quick options, such as PostUp, Address, or similar are changed, then a restart is needed.
