Thanks, I probably should have thought better about my questions, and worded them differently (or put them somewhere else).
Yes, I am just trying to see how things work. I'd like to eventually have enough experience (and I know that may be a long ways away) to add "linux web server administration" to my list of skills.
Yes, I am running the latest Ubuntu Server Edition (8.04). Yes, I installed with apt-get, but there is no vhost listed for phpmyadmin in /etc/apache2/sites-available. There is also no phpmyadmin directory in www, even though phpmyadmin is accessible from http://localhost/phpmyadmin. I'll have to look around and see what I can find.
Since I am still just learning, I will want to have experience with all of the different ways to configure. I've kept a log of what I have done, and uploaded all of the files I have changed, so I can use them as reference in the future. While there are plenty of "Install Ubuntu LAMP Server" tutorials out there, they only represent one way of doing things, and my goal is to learn. I'd like to attempt to run other distros as well, but want to feel that I have at least semi-mastered the one I am working with now before moving on.
On the side, have you or have you ever thought about writing a linux how-to book? You seem to know everything, and explain things well. There are a lot of books out there, but one that would specifically speak in detail about web server administration would be great. The one I have is 350 pages, and only 15 pages are dedicated to web server info.
