In this introductory series you will learn how use the Domain Access project to let you manage multiple "sites" with different domain names from just one Drupal installation. Domain Access "multisite" works differently from the core multisite feature in that you truly only have one site to manage. There is just one code base and one database. Domain Access takes advantage of Drupal's node access system to give the illusion of multiple sites. In this series we start off by getting some context through several presentations that explain what Domain Access offers, and why you might use it, how DNS and Apache web servers work, and what you need to understand about the node access system. Once we dive into the hands-on work, you will configure Apache to work with multiple domain names, and get Domain Access installed on your site. Then you will configure a very basic Domain Access site, learning how to share and restrict content, change themes, and set up permissions for fine-grained access control.
