WPMU Core Code

WordPress MU development code is hosted at Automattic under WordPress MU. Stable, tagged versions of WordPress MU are available in http://svn.automattic.com/wordpress-mu/tags/.

The current version of WordPress MU has now been merged with the current WordPress track. Information about current and future development versions of WordPress, with MU capabilities, can be found under the topic of Tracking the WordPress Trunk.

Using Subversion to Install WordPress MU

NOTE: Code from the WordPress trunk is often untested and sometimes has bugs. It is not recommended for production installs.

Subversion is server-side software and must be installed on your server before continuing.

Subversion is a versioning tool. At the most basic level Subversion will update the code on your WordPress installation with the latest code from the WordPress repository.

The checkout command is used for installing a fresh copy of the software from the repository to your server, and is used for the first install. The switch command is used for upgrading.

How To Install

For a fresh install, use the checkout (shorthand: co) command to install a fresh copy of the software onto your server.

Bleeding Edge Code

Early in WordPress 3.0 development, the WordPress MU project was merged with the WordPress Project. If you wish to get the latest version of WordPress, with mu features, from the SVN Repository, follow the instructions for Tracking the WordPress Trunk.

Tagged Version

To get a fresh copy of the most recent tagged version from the repository (go to http://svn.automattic.com/wordpress-mu/tags/ in your web browser to search for the latest tagged version):

1. Browse to the WordPress directory on your server
2. svn co http://svn.automattic.com/wordpress-mu/tags/2.9.2/ .
3. Follow Installing WordPress instructions

How To Upgrade

The switch command is used to revert the code on your server to another version of the code. In this case switching from an older version of the code to a newer version.

1. Browse to your WordPress directory on your server
2. svn switch http://svn.automattic.com/wordpress-mu/tags/2.9.2/
3. Follow Upgrading WordPress instructions

Using Subversion to Install Plugins

The procedure for WordPress core code is the same for plugins hosted at http://wordpress.org/extend/plugins

1. Get plugin directory name. eg. http://wordpress.org/extend/plugins/polldaddy/
2. Create new directory in the wp-content/plugins directory eg. wp-content/plugins/polldaddy
3. Go to the new plugin directory
4. svn co http://svn.wp-plugins.org/polldaddy/trunk/ (or tagged version)
5. Activate plugin through WordPress admin area
