Database
Fedora uses a relational database to support some of its functions. To simplify installation, the Fedora installer includes and can configure an embedded instance of the Derby SQL Database 10.5.3. Fedora supports four external databases: MySQL, Oracle, PostgreSQL and Microsoft SQL Server. The embedded Derby database should only be used for evaluation and development purposes; Derby should not be used for any production repository. It is recommended that you use one of the supported external databases which must be installed, configured and running before proceeding with the installation. To configure Fedora to use an external database, please see the Database section below for further instructions.
Application Server
The Fedora Repository installer includes Tomcat 6.0.20. Optionally, Fedora may be installed into any existing application server that implements Servlet 2.5/JSP 2.1 or higher. At this time, Fedora has chiefly been tested with Tomcat 5.x and Tomcat 6.0.x but users have reported running Fedora successfully with Jetty and JBoss.
