Complete Installation¶

There are three main components of the Appion system: a Database Server, a Processing Server and a Web Server. These may be installed on separate computers, or on the same computer.

The Automatic Installation Script installs a fully functional demo version of Appion. This script is intended to be used with a fresh installation of the CentOS operating system. The process is very quick and easy and includes groEL images for you to begin processing right away.

The Manual Installation Instructions are intended for a production system. We recommend using the CentOS operating system, but we include instructions for Fedora under the Alternative Options below.

Also under Alternative Options you will find instructions for installing Appion with an existing Leginon installation.
