apache starts automatically on booting my Ubuntu 8.04 system. I boot to the GUI by default so I assumed that was runlevel 5. Thus, I renamed

/etc/rc5.d/S91apache2

to

/etc/rc5.d/K91apache2

but the service still started after a reboot. Am i on the wrong runlevel? How can i disable apache's automatic start on boot?

Ubuntu is Debian based so only uses two runlevels rather than the 5 seen in most other distros/Unices. You can disable it with

sudo update-rc.d -f apache2 remove

Thanks for the quick reply! Two questions.

What file would that command be modifying? I'd like to be able to see what it is doing so I know what is going on.


Also, what is the point of these directories if runlevels 0-6 do not exist?

Maybe this will help -

How-To: Managing services with update-rc.d | Debian/Ubuntu Tips & Tricks

Basically update-rc.d manages all of the symlinks in the various runlevels to the original init script in question. In Debian systems runlevels 2-5 are identical but I think they're just left there to allow the more traditional system to be restored if required or possibly for compliance.

That worked! It changed the links for each runlevel automagically. Also, thanks for the link, it was very useful.

I appreciate your help!
