How can I disable autostart for a service without uninstalling? For example, I'd like to leave tomcat installed, but I don't want it turning on every time I restart.

This should do the trick:

Open terminal (Ctrl + Alt + T) and enter the following command:

sudo update-rc.d tomcat disable

Basically update-rc.d will modify existing runlevel links for the script /etc/init.d/tomcat by renaming start links to stop links.

Note that the default tomcat service name is "tomcat7" in ubuntu 14. – eaykin Feb 16 '15 at 12:45
    
If your tomcat is tomcat6 you will need to do "sudo update-rc.d tomcat6 disable" else you will get error. – Dung Jun 10 at 16:11

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

This one worked for me. I had uninstalled tomcat manually yet it was trying to shut it down before any reboot. Disable without -f parameter yelded "file does not exists". – amenadiel Sep 2 '13 at 11:54

More generic and more visual, with a nice UI: sysv-rc-conf

Uncheck the boxes for tomcat7 (runlevels 2 to 5), quit and that's it.

cool, that's a tool I haven't seen before. It was useful to confirm that the update-rc.d command actually had worked – STW Mar 19 '14 at 1:14
    
This tool is great, it was the thing I was searching for. Thank you very much for it. – Utku Özdemir Apr 24 '14 at 7:07

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

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

+ 1 million, this is what worked for me. I was trying to stop transmission-daemon from starting on startup and the update-rc.d method used to work, but it looks like its been converted to an Upstart script now so this is the only method that works – Erin Drummond Mar 7 '15 at 6:46
