Install a MediaWiki codebase

Install a MediaWiki codebase Organic Design procedure

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> Shared extensions dir primarily from OD extensions svn repo then others added from wikimedia etc /var/www/extensions Database dumps used as initial templates for new wikis /var/www/empty-1.15.1.sql /var/www/empty-1.16.sql Tools and system-wide OD/Wikia configuration from the OD tools svn repo /var/www/tools Installed MediaWiki codebases /var/www/mediawiki-1.6.7/ /var/www/mediawiki-1.9.3/ /var/www/mediawiki-1.10.0/ /var/www/mediawiki-1.11.0/ /var/www/mediawiki-1.15.1/ /var/www/mediawiki-1.16alpha/ /var/www/mediawiki-svn/ Example of template filesystem Symbolic link to common MediaWiki instance /var/www/wikis/template/wiki -> /var/www/mediawiki-svn/ </bash>

Download

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 mv /tmp/mediawiki-1.13.2 /var/www </bash>

Or if you prefer, obtain the current development version from the Subversion repository:

<bash> svn co http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3 /var/www/mediawiki-svn </bash>

You may like to checkout the source tree of the latest skins:

<bash> svn co http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3/skins /var/www/skins-phase3-trunk </bash>

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. If it is a local installation /var/www/domains/setup.localhost and include setup.localhost in your etc/hosts: 127.0.0.1 localhost setup.localhost
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 (but please note, you must use a table prefix with trailing underscore for add-db to work with it as a template!). Use your own account for sysop rather than "WikiSysop". If it is a local installation http://setup.localhost
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 to the end of the script: 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 relevent, but the template-db's may need a column added for DPL, see OD:01 May 2007

Wiki Database Details

Note that the wiki DB settings are now managed and set from /var/www/tools/wikid.conf, see the wikid.conf.sample file for an example. The wikia.php file which is automatically included in all wikis in the wikia will extract the DB details from the wikid.conf file.
