Until you get up to speed on the myriad of command line utilities and distro specific config tools, I would STRONGLY suggest you check out a utility called WEBMIN - it allows you to configure almost every aspect of your system and daemons such as apache , ftp, etc. DO GO BACK AND LEARN THE COMMAND LINE THOUGH!
here is how to get it going - really simple
go to www.webmin.com
and download the RPM install file to a directory you can find later.
go to the directory and double click on the RPM file
a package manager utility (basically a software installation util) will open - every distro is a little different, but you will basically need to accept/or confirm that you want to go ahead with the install. this part should be pretty self explanatory
reboot - this step is so you dont have to load the daemon manually
open your favorite web browser and type http://localhost:10000
Webmin will prompt you to enter the root username and password
I believe that the section to start apache automatically is under the SYSTEM applet in Webmin... look for a util that lists all the services on your ssystem, allowing you to checkbox those you wish to launch at startup.
