disable services on startup in ubuntu [duplicate]

I installed these applications on my Ubuntu:

These applications run every time the computer turns on.

How can I prevent these applications from running on start up?
So, these applications only run if I do "service nginx start".

Solution 1:

Use:

systemctl disable <service>

If you are not using systemd (Ubuntu 14.10 and earlier) use:

update-rc.d -f <service> remove

The following command will give you a list of all services on your machine:

service --status-all

You should be able to find the names of the services you want to disable in there.

For more details, see enabling-and-disabling-services and for the very long answer see this post (as already mentioned by @muru).
