new to unix web server

Hi,

I´m trying to give a new life to my old Pentium I using him as a simple
web server... just to learn a little more about all this stuff - i´m a
beginner.
I´ve installed Red Hat 9 and now i have my machine working perfectly.
Can anyone help me to configure my machine as a web server or give me
any simple documentation about that so i can read it?

Thanks

N Marques
