Disable service

Disable autostart for a service without uninstalling

update.rc

The disable|enable API is not stable and might change in the future. I suggest you use the following command to remove all the symlinks in /etc/rc?.d/:

update-rc.d -f tomcat remove

to disable

update-rc.d -f tomcat disable

upstart

For upstart jobs, you need to disable service like this (e.g. mysql):

$ sudo -s
# echo "manual" > /etc/init/mysql.override

genarally

echo manual | sudo tee /etc/init/SERVICE.override

Enable service

Enable a service to autostart

update.rc

Create a service with defaults, foobar example

update-rc.d foobar defaults


upstart

If you put the MySQL service into manual mode and want enable again you can simply do

sudo rm /etc/init/mysql.override


SYSTEMD

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.
