Installing the FreePBX application
FreePBX is a program that works together with Asterisk and a number of other programs to make it easy to set-up and configure a VOIP PBX. By itself, FreePBX won't do anything. You also need to install Linux, Asterisk, Dahdi, Postfix/Sendmail, TFTP, and a host of other programs.
If you are not an expert with Linux and its dependent components, you'll want to choose and install a Distro. If you are an expert, you can simply install FreePBX on top of an existing Linux/Asterisk installation.
We'll cover both, below.
The Easy Way (use a Distro)
There are a number of distributions ("Distros") available that will automatically install include FreePBX, Linux, and all the other components you need. When you use a distribution, you avoid having to learn how to install, compile, and configure each of these required components. A good distribution comes with everything you need to get started.
There are several distributions available, including the FreePBX Distro, PBX In A Flash, AsteriskNOW and Elastix. The easiest way to install FreePBX is to download the FreePBX Distro from the download page.

Be aware that doing so almost always involves wiping the contents of every drive on the computer, so only install a distro on a machine whose contents you don't mind losing!
For some suggestions on what to do after you finish the installation read about the First Steps After Installation.
For information on the release versions and how to upgrade the FreePBX Distro read Upgrading the FreePBX Distro.
Be sure not to confuse "FreePBX" (which is a program) with the FreePBX Distro (which is a distribution that includes FreePBX and all the other stuff you need).
The Hard Way
The hard way to install FreePBX is to set-up a machine running Centos 5.5, Asterisk 1.4/1.6 or 1.8, and all other required applications.
FreePBX is an application that is built on the LAMPA stack, so in theory any system running this stack could run FreePBX.
If you already have Linux, Asterisk, and all related applications installed, you can download and install FreePBX using the following commands:
cd /usr/src wget http://mirror.freepbx.org/freepbx-2.9.0.tar.gz tar zxvf freepbx-2.9.0.tar.gz cd /freepbx-2.9.0 ./start_asterisk start ./install_amp
