Installing MediaWiki Guide

MediaWiki, the Wiki engine powering this site, is fully open-source and free. It seems to be robust, and reasonably fast. Configuring and installing it, however, is not so easy. This guide is a tutorial for MediaWiki administrators.

Prerequisites

• Apache
• PHP
• MySQL

Optional Software

• APC. This is a PHP accelerator.
• memcached. This a daemon caching SQL requests in memory. If you run two Wikis on the same machine, beware that it can cause serious problems. If there is a single memcached daemon running, and both Wikis use it, they will interfere and one Wiki will end up serving the contents of the other. A solution can be to run memcached on several machines, or maybe on the same machine but with different ports. However, this last option on Mac OS X this seems to be tricky.

Installation

Installation is easy, just download MediaWiki from Sourceforge and uncompress the tarball in a directory that Apache can serve. Then follow the instructions on the README to perform the initial configuration. It involves running a PHP script that will configure the Wiki for you.

Configuration

• Using memcached

• Obtaining nice URLs

Usage

• Editing Guide, very helpful
