How to set up MediaWiki within XAMPP
  1. Download the latest version of MediaWiki (approx. 1.8 Mb).
  2. Unzip the downloaded file to X:\xampp\htdocs where X stands for the drive letter of your XAMPP installation.
  3. This will create a directory with a name like mediawiki-1.4beta6, depending on the version you downloaded.
    For ease of use, rename the directory to mediawiki (optional, although the instructions below assume you have done this).
  4. Point your browser to: http://localhost/mediawiki

    This will give you a page with a link to config/index.php, which you should click.

  5. Set up your wiki by filling out the setup page and clicking Install.
  6. If all went well, you will see this message at the bottom of the page:

    Success! Move the config/LocalSettings.php file into the parent directory, then follow this link to your wiki.

    Use Explorer to Cut the file X:\xampp\htdocs\mediawiki\config\LocalSettings.php

    Then Paste that file to X:\xampp\htdocs\mediawiki\LocalSettings.php

  7. That's it, you can now view your Wiki and start adding content.
