Can't control Apache

[happypandaface]

I installed Apache using

# apt-get install apache2

But I didn't know how to work it, so I went to the apache website, and unpacked apache to /usr/lib/apache/ then ran

# /usr/lib/apache/bin/apachectl start

Like it told me to in the instructions, but it gave me this:

httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

So I decided to check to see what program was using this port so I used netstat (I forgot the actual command), and guess what came up? Apache.
So I opened a browser and went to "localhost:80" and a webpage came up that said "It works!" just like apaches suppose to do. So I tried to close apache using:

# /usr/lib/apache/bin/apachectl stop

But this came up:

httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
httpd (no pid file) not running

And so I tried opening localhost:80 and it still said "It works!"
So I decided to remove apache completely:

# apt-get remove apache2

And it removed one package, but it still works!
I have no Idea how this is happening, and I have no idea how to shut it down.

the installed service controller should be in /etc/init.d
the config files for apache should also be in /etc, probably under apache2 folder

So, what do I do with these files? I want accomplish either of two things: Have control over the apt-get install or use the one I installed. I believe both have their strengths and weaknesses. The apt-geted one is supported by ubuntu, but the one I installed is easy to control, because its all in one file I believe, I actually know what file is being shared on the webserver, and have edited the index.html. And its a newer version, so I'd rather use the one I installed. So how do I get rid of or disable the other one?

Ok, I fixed it. I needed to do:

# apt-get autoremove

I think thats it, maybe something like that. Anyway I that got rid of the old Apache installation completely. Read my other posts to see what I did exactly.

I'm posting this for people to find this thread if they have the same problem.
