Installation

Before you start, make sure that your system meets the requirements of Atrium.

The process of installing Atrium is very similar to installing Drupal. Please follow the Drupal installation instructions but choose the Atrium Installer rather than the default Drupal install profile when you are prompted during the installer.

Need help?

We have a community site which has documentation about all aspects of Atrium. This site also hosts our issue tracker where bugs and improvements are report, suggested and fixed.

You can also come chat with us in IRC. We're hanging out in #open_atrium on freenode.net.

Server/environment

Atrium has been tested with the following software successfully. Your mileage may vary on other configurations:

• PHP 5.2
• PHP GD extension
• 64MB memory limit
• MySQL 5
• Apache
• Apache mod_rewrite module for clean urls

Clients

Atrium supports the major standards-compliant browsers, but we do most of our testing against:

• Firefox 2+
• Safari 3+
• Internet Explorer 7+

Internet Explorer 6 is not supported. Clients with javascript disabled are also not supported.

The Atrium core theme Ginkgo is designed for at least a 1024x768 resolution, but there is a Ginkgo Thin variant that can be used with 800x600.

On the download page we offer complete installable packages of Open Atrium. These packages are the quickest and easist way to install Open Atrium, using them is highly recommended.

However it is also possible to assemble Open Atrium yourself using the same process we use. Open Atrium is a Drupal install profile and which lives on drupal.org. Our install profile references many Drupal modules and other projects, so we use Drush make build system to pull all the code together into one package. Instructions to do this are maintained our [community site].
