Obviously you can just download it from the main site, do a quick google search for apache and find, and download the .tgz files. Unzip, (./confgure), (make), (make install), and bam you got an apache server. The easiest method by far is either yum or apt-get. If you open a terminal window in root simply type “yum install httpd”, or “apt-get install httpd”, and apache will be auto installed. Yum is usually preinstall on most linux distributions (I know its on Fedora Core 6). Apt does essentially the same thing as yum, but I installed both for shits and giggles. If Apt is not pre-installed, and you want to install it, use “yum install apt”, and bam it will auto install. These commands can only be used while logged in under root therefore if your logged in on a user first open the terminal window, then type “su”, enter the root password and you will then login as root and have full “yum” or “apt” control.
