Building A Linux Internet Server
Eckel & Hare
Once you understand Linux, this book is a good guide to all the issues involved in getting your box connected to the 'net. You don't need this book as all of the info you need can be gleaned from the Network Administrator's Guide and the various HOW-TOs, man pages and Apache documentation but it might make life easier if you are in a hurry and don't want deep understanding of everything involved.
