Installation Guidelines: Linux (Production: Cherokee/PostgreSQL)
Table of Contents
Installs that we maintain are usually done using Cherokee & PostgreSQL
- Cherokee is a high-performance web server with a graphical admin UI
- PostgreSQL is a database with powerful geospatial support
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 Trunk versions of both Web2Py & Eden. This can occasionally cause teething problems, so if you want a safer route then you may be better off with the Apache/MySQL option or modifying these scripts to use the Stable versions of Web2Py & Eden.
