Online docs will do...
I bought this book, but it turned out that I didn't really have to use much of it. The source program package from apache comes with a complete, up-to-date installation guide, online docs, pointers to FAQ and other info. If you are trying to set up Apache in the absense of any internet access (some kind of a boot-strapping process that someone might have to do in some special settings), this book might be useful. But that's usually not the case, and I wonder who would bother? For quick reference purposes, O'Reilley's Webmaster in a Nutshell would do a much better job for dollar.
