As anyone who as tried to run WordPress MU on a web server knows, you need to have a hosting partner who has the capability of handling the server requirements to run WordPress MU. I’m referring not only to the Apache, MYSQL and PHP requirements:
* PHP 4.2 or greater
* MySQL 4.0 or greater
* The mod_rewrite Apache module
I’m also referring to the VHost and DNS configurations that need to be made in the httpd.conf file at the server level. You will need this configuration if you intend to use the subdomain feature with WordPress MU. You can use either the subdomain or subdirectory feature in WordPress MU. This refers to the URL of each of the user blogs within your WordPress MU network:
- Subdirectory Method: http://yourdomain.com/user
- Subdomain Method: http://user.yourdomain.com
The Subdomain Method is the most popular, and most recommended (most MU plugins are created for use with the subdomain method).
