An easy method to enable and disable services in Debian based distros is to use sysv-rc-conf
sudo apt-get install sysv-rc-conf
Then follow the onscreen instructions for moving around, viewing all the services, enabling and disabling services for specific run levels, or manually starting and stopping services.
heres a screenshot.. http://screenshots.debian.net/package/sysv-rc-conf
remember the default run-level for Debian based Distros is 2
, not 3 or 5 like many other distros. Typically runlevels 2-5 are set the same in Debian unless you have done something custom.
I believe the service is named apache2
in Debian based distros.. httpd is what redhat based distros call it.. I wouldn't think Ubuntu changed the name for the apache service but one can never tell
