Starting with Ubuntu 15.04, Upstart will be deprecated in favor of Systemd. With Systemd to manage the services we can do the following:
systemctl start SERVICE – Use it to start a service. Does not persist after reboot
systemctl stop SERVICE – Use it to stop a service. Does not persist after reboot
systemctl restart SERVICE – Use it to restart a service
systemctl reload SERVICE – If the service supports it, it will reload the config files related to it without interrupting any process that is using the service.
systemctl status SERVICE – Shows the status of a service. Tells whether a service is currently running.
systemctl enable SERVICE – Turns the service on, on the next reboot or on the next start event. It persists after reboot.
systemctl disable SERVICE – Turns the service off on the next reboot or on the next stop event. It persists after reboot.
systemctl is-enabled SERVICE – Check if a service is currently configured to start or not on the next reboot.
systemctl is-active SERVICE – Check if a service is currently active.
systemctl show SERVICE – Show all the information about the service.
sudo systemctl mask SERVICE – Completely disable a service by linking it to /dev/null; you cannot start the service manually or enable the service.
sudo systemctl unmask SERVICE – Removes the link to /dev/null and restores the ability to enable and or manually start the service.
Just copied notes. 😉 nJoy
