@title Installation Guide
@group intro

This document contains basic install instructions to get Phabricator up and
running.

= Installation Requirements =

Phabricator is a LAMP application suite, so you basically need LAMP:

  - **Linux**: Some flavor of Linux is required. MacOS is an acceptable flavor
    of Linux. Windows is not an acceptable flavor of Linux. Phabricator will not
    install or work properly on Windows. (If you want it to, send patches.)
    Phabricator is actively developed on OSX and Amazon's Linux; if you run
    into issues on other flavors, send patches or complaints.
  - **Apache**: You need Apache. You might be able to use something else, but
    you're on your own.
  - **MySQL**: You need MySQL.
  - **PHP**: You need PHP 5.2 or newer.

You'll probably also need a **domain name** and you'll certainly need
**a computer** with a connection to **the internet**.

= Installing Required Components =

This document assumes you have "yum". If you don't, substitute whatever package
manager you do have, or go hunt down all this stuff and build it from source
if you want.

Install things we need:

  sudo yum install git httpd php mysql-server php-mysql php-devel

If you already have LAMP setup, you've already got everything you need.

Now that you have git installed, grab Phabricator and its dependencies:

  $ cd somewhere/ # pick some install directory
  somewhere/ $ git clone git://github.com/facebook/libphutil.git
  somewhere/ $ git clone git://github.com/facebook/arcanist.git
  somewhere/ $ git clone git://github.com/facebook/phabricator.git
  somewhere/ $ cd phabricator
  somewhere/phabricator/ $ git submodule update --init

= Installing APC (Optional) =

Like everything else written in PHP, Phabricator will run much faster with APC
installed. You likely need to install "pcre-devel" first:

  sudo yum install pcre-devel

Then you can either install via PECL:

  sudo yum install php-pear
  sudo pecl install apc

...or grab the package from PECL directly and follow the build instructions
there:

  http://pecl.php.net/package/APC

Installing APC is optional but **strongly recommended**, especially on
production hosts.

Once APC is installed, test that it is available by running:

  php -i | grep apc

If it doesn't show up, add:

  extension=apc.so

..to "/etc/php.d/apc.ini" or the "php.ini" file indicated by "php -i".
