Autostart WireGuard in Linux System
Step 1: Generate a valid and working WireGuard configuration file /etc/wireguard/wg0.conf.
Note: You may have to replace the Endpoint hostname with the WireGuard server IP address in the WireGuard configuration file. DNS may or may not be applied when the system brings the wg0 interface up.
Step 2: Add the WireGuard service to the system:
sudo systemctl enable wg-quick@wg0.service
sudo systemctl daemon-reload
Step 3: Start the new service immediately:
sudo systemctl start wg-quick@wg0
Step 4: Reboot your computer system to verify the automatic connection on startup works as expected.
Step 5: Check the service status:
systemctl status wg-quick@wg0
Step 6: To remove the service and clean up the system:
sudo systemctl stop wg-quick@wg0
sudo systemctl disable wg-quick@wg0.service
sudo rm -i /etc/systemd/system/wg-quick@wg0*
sudo systemctl daemon-reload
sudo systemctl reset-failed
