Enabling and Disabling Services

The above commands are useful for starting or stopping commands during the current session. To tell systemd to start services automatically at boot, you must enable them.

To start a service at boot, use the enable command:

sudo systemctl enable application.service

This will create a symbolic link from the system's copy of the service file (usually in /lib/systemd/system or /etc/systemd/system) into the location on disk where systemd looks for autostart files (usually /etc/systemd/system/some_target.target.wants. We will go over what a target is later in this guide).

To disable the service from starting automatically, you can type:

sudo systemctl disable application.service

This will remove the symbolic link that indicated that the service should be started automatically.

You can manually start any service during boot-up, e.g mysql, you need to set systemd to disable the service from activate when you OS loaded. Just run :

$ sudo systemctl disable mysqld.service

If you want the service to run automatically during boot-up change the parameter disable to enable.

You saying that mysql took lot of time during shutdown. Then what you need is, run the services only when needed with

$ sudo systemctl start mysqld.service

after done with that, you need to shutdown the services via

$ sudo systemctl stop mysqld.service

For personal use and if you are using gnome to install this services-systemd extension, just add the service and use the GUI to start and stop the services. It much effective for personal use.
