Installation Guidelines: Linux (Production: Apache/MySQL)

Production Installs that are maintained by others are usually installed with Apache & MySQL.

Apache is a well-supported & flexible web server which can run Sahana well through mod_WSGI
MySQL is a well-supported database with an easy-to-use Admin UI (phpMyAdmin)

The simplest way to install is using our attached installation scripts.

This is split into 2 halves, as the 1st script can create a base image which is then customised per-instance using the configure script.

Note: We install using the latest Stable versions of both Web2Py & Eden. Problems can still occur, however.
