question: a good book on webserver administration?

I make websites, and sometimes i like to work with my own VM. I have been using linux for a while, and i feel i have a decent understanding on how it works, but when it comes to setting up a webserver for production use (nothing really critical or filled with "delicate" infos) i'm not so comfortable.

So, i'm looking for a book (or more) that can give me a good solid base knowledge on such things. Thank you.
