Procedure.svg Install a MediaWiki codebase
Organic Design procedure


Note.svg Note: There is an apache rewrite bug in MediaWiki 1.11.x -see MW:Manual:Short_URL/Page_title_--_Working_method_with_mediawiki-1.11


This article describes installing a new version of the MediaWiki software itself. This is a framework which can be thought of as a class which provides the interface structure and database schema for any instances of the software which are separate evolving databases. This process is also useful for creating a duplicate of an existing codebase for experimentation.

File structure

<bash>
  1. Installed versions

/var/www/mediawiki-1.6.7/ /var/www/mediawiki-1.9.3/ /var/www/mediawiki-1.10.0/ /var/www/mediawiki-1.11.0/

  1. Example of template filesystem Symbolic link to common MediaWiki instance

/var/www/wikis/template/wiki -> /var/www/mediawiki-1.10.0/ </bash>

Download

  1. Download a version of MediaWiki to the server you want to install it on. Using wget on a server to download a version e.g.
<BASH>

cd /tmp wget --proxy http://download.wikimedia.org/mediawiki/1.13/mediawiki-1.13.2.tar.gz tar -zxvf mediawiki-1.13.2.tar.gz su mv /tmp/mediawiki-1.13.2 /var/www </BASH>

Codebase hacks
  1. Change the constants in Article.php functions getBlankingAutosummary, getAutosummary and the end of delete to $GLOBALS['wgTruncatedCommentLength'] (bugzilla report 2007-10-02 11543)

Installation steps

  1. Unpack the tar.gz distribution into /var/www leaving the directory name of the version untouched. The config directory must be set to chmod a+w config
  2. Set the /var/www/domains/setup.organicdesign.co.nz symlink to point to the new codebase
  3. A symlink needs to be added in the codebase during initial setup called wiki which points to it's parent, the codebase dir e.g. ln -s /var/www/mediawiki-1.11.1/ wiki
  4. Go to http://setup.organicdesign.co.nz/wiki/config in your browser and run through the install the db user bender, and any template db name. Use your own account for sysop rather than "WikiSysop".
  5. Move the config/LocalSettings.php into the main /wiki directory
  6. Edit the LocalSettings.php file, remove the db user, password and prefix and append include('extensions/wikia.php');
  7. Replace the extensions directory with a symlink to /var/www/extensions
  8. Run make in the wiki/math directory
  9. Add the DPL DB update shown at DPL:DPL:Manual - Source and Installation (after we figure out why it's not working!)
  10. Create a template database for major releases of MediaWiki (either copy and upgrade an existing template, or add to the base install)
mysqldump -u user -p db-name > /var/www/empty-x.xx.sql
Note: see section below for DB user details
  1. Not sure if this is still relavent, but the template-db's may need a column added for DPL, see OD:01 May 2007

MediaWiki MySQL user

Mediawiki is setup with the mysql user account Bender with the password specified as in MW:LocalSettings.php through the include of Wikia.php. User Bender has privileges to create and access all the wikia databases.
