Configuration Management ########################

Introduction

---

The goal of the edx/configuration project is to provide a simple, but flexible, way for anyone to stand up an instance of Open edX that is fully configured and ready-to-go.

Before getting started, please look at the Open EdX Installation options_, to see which method for deploying OpenEdX is right for you.

Building the platform takes place in two phases:

• Infrastructure provisioning
• Service configuration

As much as possible, we have tried to keep a clean distinction between provisioning and configuration. You are not obliged to use our tools and are free to use one, but not the other. The provisioning phase stands-up the required resources and tags them with role identifiers so that the configuration tool can come in and complete the job.

Note: The Cloudformation templates used for infrastructure provisioning are no longer maintained. We are working to move to a more modern and flexible tool.

The reference platform is provisioned using an Amazon CloudFormation_ template. When the stack has been fully created you will have a new AWS Virtual Private Cloud with hosts for the core Open edX services. This template will build quite a number of AWS resources that cost money, so please consider this before you start.

The configuration phase is managed by Ansible_. We have provided a number of playbooks that will configure each of the Open edX services.

Important: The Open edX configuration scripts need to be run as root on your servers and will make changes to service configurations including, but not limited to, sshd, dhclient, sudo, apparmor and syslogd. Our scripts are made available as we use them and they implement our best practices. We strongly recommend that you review everything that these scripts will do before running them against your servers. We also recommend against running them against servers that are hosting other applications. No warranty is expressed or implied.
