Recommendation of books to setup and admin a web server in Linux

I am going to setup and admin a web server in Ubuntu Linux distribution. I installed it by default setting, and seems all works fine, and now I need to setup it to be a virtual web host server, mainly I will create more accounts and for each account, I will setup its home/folder, and ftp, so the user with the account can upload their PHP scripts to it, also I would like to make home/bin, home/lib for the account, so they can use SSH too, to install local binary or libs, even more.. I am thinking to read some books, but I don't know which one is good for me basically it could have something about how to setup virtual web host server, admin it, and how to make it secure.
