Burn yourself a Knoppix ISO, boot from that CD, go to the KNOPPIX menu, open a root shell, type knx-hdinstall, set up your swap and main partition when that puts you in cfdisk (you should look around to learn the basics of Linux partitions first), and let it automagically handle the rest of the installation. You'll end up with a cutting-edge derivation of Debian with lots of goodies. Certainly enough to run apache.
Now, stock Debian is safer (older, more stable versions of stuff), but Knoppix is by far the easiest install. If you're serious about running a production server, Gentoo is better than either - but you have to be into compiling stuff for that, it's a lot more work.
