How do I turn off the sql server by default on startup? [duplicate]

As soon as I turn on my system and run the command :

service mysql status

It shows that the service has been activated since the PC was turned on, I want it to be off my default and when I want to, I should be able to activate it by :

service mysql start

Is this possible?


Solution 1:

On Ubuntu 16.04 and newer use

systemctl disable mysqld.service

Notice the difference: stop to stop the running service and disable to disable autostart.
