Open edX Platform

Purpose

The Open edX Platform is a service-oriented platform for authoring and delivering online learning at any scale. The platform is written in Python and JavaScript and makes extensive use of the Django framework. At the highest level, the platform is composed of a monolith, some independently deployable applications (IDAs), and micro-frontends (MFEs) based on the ReactJS.

This repository hosts the monolith at the center of the Open edX platform. Functionally, the edx-platform repository provides two services:

CMS (Content Management Service), which powers Open edX Studio, the platform's learning content authoring environment; and
LMS (Learning Management Service), which delivers learning content.

Documentation

Documentation can be found at https://docs.openedx.org/projects/edx-platform.

Getting Started

For Production

Installing and running an Open edX instance is not simple. We strongly recommend that you use a service provider to run the software for you. They have free trials that make it easy to get started: https://openedx.org/get-started/

However, if you have the time and expertise, then it is is possible to self-manage a production Open edX instance. To help you build, customize, upgrade, and scale your instance, we recommend using Tutor, the community-supported, Docker-based Open edX distribution.

You can read more about getting up and running with a Tutor deployment at the Site Ops home on docs.openedx.org.

For Development

Tutor also features a development mode which will also help you modify, test, and extend edx-platform. We recommend this method for all Open edX developers.

Bare Metal (Advanced)

It is also possible to spin up an Open edX platform directly on a Linux host. This method is less common and mostly undocumented. The Open edX community will only be able to provided limited support for it.

Running "bare metal" is only advisable for (a) developers seeking an adventure and (b) experienced system administrators who are willing to take the complexity of Open edX configuration and deployment into their own hands.

System Dependencies

OS: * Ubuntu 20.04

Ubuntu 22.04

Interperters/Tools:

Python 3.11
Node 18

Services:

MySQL 8.0
Mongo 7.x
Memcached

Language Packages:

Frontend:
- npm clean-install (production)
- npm clean-install --dev (development)
Backend build:
- pip install -r requirements/edx/assets.txt
Backend application:
- pip install -r requirements/edx/base.txt (production)
- pip install -r requirements/edx/dev.txt (development)
Some Python packages have system dependencies. For example, installing these packages on Debian or Ubuntu will require first running sudo apt install python3-dev default-libmysqlclient-dev build-essential pkg-config to satisfy the requirements of the mysqlclient Python package.

Build Steps

Create two MySQL databases and a MySQL user with write permissions to both, and configure Django to use them by updating the DATABASES setting.

Then, run migrations:

./manage.py lms migrate
./manage.py lms migrate --database=student_module_history
./manage.py cms migrate

Build static assets (for more details, see building static assets):

npm run build  # or, 'build-dev'

Download locales and collect static assets (can be skipped for development sites):

make pull_translations
./manage.py lms collectstatic
./manage.py cms collectstatic

Set up CMS SSO (for Development):

./manage.py lms manage_user studio_worker [email protected] --unusable-password
# DO NOT DO THIS IN PRODUCTION. It will make your auth insecure.
./manage.py lms create_dot_application studio-sso-id studio_worker 
    --grant-type authorization-code 
    --skip-authorization 
    --redirect-uris 'http://localhost:18010/complete/edx-oauth2/' 
    --scopes user_id  
    --client-id 'studio-sso-id' 
    --client-secret 'studio-sso-secret'

Set up CMS SSO (for Production):

Create the CMS user and the OAuth application:

./manage.py lms manage_user studio_worker  --unusable-password
./manage.py lms create_dot_application studio-sso-id studio_worker 
    --grant-type authorization-code 
    --skip-authorization 
    --redirect-uris 'http://localhost:18010/complete/edx-oauth2/' 
    --scopes user_id

Log into Django admin (eg. http://localhost:18000/admin/oauth2_provider/application/), click into the application you created above (studio-sso-id), and copy its "Client secret".
In your private LMS_CFG yaml file or your private Django settings module:

Set SOCIAL_AUTH_EDX_OAUTH2_KEY to the client ID (studio-sso-id).

Set SOCIAL_AUTH_EDX_OAUTH2_SECRET to the client secret (which you copied).

Run the Platform

First, ensure MySQL, Mongo, and Memcached are running.

Start the LMS:

./manage.py lms runserver 18000

Start the CMS:

./manage.py cms runserver 18010

This will give you a mostly-headless Open edX platform. Most frontends have been migrated to "Micro-Frontends (MFEs)" which need to be installed and run separately. At a bare minimum, you will need to run the Authentication MFE, Learner Home MFE, and Learning MFE in order meaningfully navigate the UI.
