How to install WordPress MU?
- Download and unzip the WordPress MU package. The unzipped files will be created in a directory named “wordpressmu”
- Create a database for WordPress MU on your web server, as well as a MySQL user who has all privileges for accessing and modifying it.
- Place the WordPress MU files in the desired location on your web server:
a) If you want to integrate WordPress MU into the root of your domain (e.g. http://domain.com/), move or upload all contents of the unzipped WordPress MU directory (but excluding the directory itself) into the root directory of your web server.
b) If you want to have your WordPress MU installation in its own subdirectory on your web site (e.g. http://domain.com/blogs/), rename the directory wordpressmu to the name you’d like the subdirectory to have and move or upload it to your web server. For example if you want the WordPress MU installation in a subdirectory called “blog”, you should rename the directory called “wordpressmu” to “blog” and upload it to the root directory of your web server.
4. Run the WordPress MU installation script by accessing index.php in your favorite web browser.
