According to Philip Greenspun: -

“The ArsDigita Community System (ACS) is a toolkit of software that will help you build Web services with a collaborative dimension, ranging from knowledge management within companies to B2C ecommerce to product support and community among the customers. The software is free and open-source and has been tested in heavy use since 1995.” -

What's OpenACS? OpenACS was born when Don Baccus, Ben Adida, et al decided to port ACS from Oracle to PostgreSQL, thus making it a fully open-source solution. -

OpenACS 4.5 is the next generation of the web toolkit. It's based on ACS 4, but no longer follows ArsDigita development.

Don Baccus leads the development and numerous developers (and non-developers) contribute from around the world. -
-This document will describe how to install OpenACS 4.5 from scratch, using the source code. We will assume that you have an OS installed, but we'll discuss this more in the next section. For most of this guide, we will assume that you are using Linux on a PC, but we'll also point you to excellent step-by-step guides for other operating systems. -
-You will need a PC (or equivalent) with at least these minimum requirements: -

128 MB RAM - (much more if you want Oracle)
4 GB hard drive

Note that these are minimum requirements to get a development system up and running. For a production system, we recommend you read about the ArsDigita Server Architecture -

Running a reliable database-backed web server requires experience with the server's environment, in this case UNIX. UNIX is not always an intuitive environment and this guide cannot hope to explain every nuance. You should be comfortable with the following tasks before attempting an installation: -
-+
Adding users, groups, setting passwords -
+
Starting an X server and running an X program remotely -
+
Basic file management using cp, rm, mv, and cd -
+
Compiling a program using a Makefile -
+
If you've never done these things before, consider exploring UNIX in greater depth before installing OpenACS. Some useful resources for doing this are described in the Resources section. -

All of the software that you will need is free and open-source, except for Oracle. You can obtain a free copy of Oracle for development purposes. This is described in the Acquire Oracle section. -

We'll point out where the error logs for the various pieces of software are. Output from those logs will help us help you. Don't worry if you feel overwhelmed by all the information in the error logs. Over time, you'll find that they make more and more sense. Soon, you'll actually look forward to errors so that you can run to the log and diagnose the problem. -
