This document describes how to install and setup Alfresco Content Server Community Edition by “Alfresco Software inc.” on a Fedora based webserver from a WAR package on a Tomcat webserver with postgreSQL database as backend. For other distributions there might be minor changes as to the software prerequisites installation procedures. I took my time to write this tutorial up, since I was unable to find any complete setup procedure on the Internet, mainly because there is a .bin executable, which install all in one easy step. Therefore this guide is intended to those who, like me, want to have as much control and understanding as possible and for those, who would want to install this server into already existing infrastructure and do not wish to dig wiki pages much. Moreover, by default, server from .bin installation runs as root and this is a potential threat to security. This guide will not only help install the product, but also understand why certain points are done the way they are done (this is most helpful for users with little or no knowledge who, like me some time ago, have only started using Linux).
What is Alfresco?
Should I say it in simple manner, this is the Sharepoint open source competitor, which is fully compliant with sharepoint protocol, yet powerful enough that it would take a book to cover everything in detail.
There are two versions of it, non-free Enterprise edition which includes classic commercial support from developer and a free Community edition, whereas the only support you get are posts across the Internet from others brave souls.
