Deploying a Django App with mod_wsgi on Ubuntu 14.04

This article provides a comprehensive guide to deploying Django applications using mod_wsgi on Ubuntu 14.04. It covers setting up a "Hello World" application and then deploying it to a production server using Apache and mod_wsgi.

Key Concepts:

• Django: A high-level Python web framework known for rapid development and scalability. Popular sites like Instagram and Pinterest utilize Django.
• mod_wsgi: An Apache module that acts as a bridge between Apache web server and Python WSGI applications (like Django).
• WSGI (Web Server Gateway Interface): A standard Python specification for communication between web servers and web applications.

Deployment Steps:

The tutorial meticulously details each step, from creating a basic Django application to configuring Apache for production deployment. Here's a summarized overview:

1. Setting up the Django Application:

• Create a new user (optional): Best practice for security, especially on servers.
• Install Python package manager (pip): Essential for managing Python dependencies.
• Install Django: Using pip install Django (or a specific version if needed).
• Install project dependencies (optional): If using requirements.txt, run pip install -r requirements.txt.
• Create a "Hello World" application: The tutorial guides you through creating a simple Django project and app with a basic view.

2. Deploying with Apache and mod_wsgi:

• Install Apache2: sudo apt-get install apache2
• Install mod_wsgi: sudo apt-get install libapache2-mod-wsgi (or libapache2-mod-wsgi-py3 for Python 3).
• Modify directory structure: Organize your project to include an apache directory for WSGI configuration files (wsgi.py, override.py).
• Create the WSGI script (wsgi.py): This script acts as the interface between Apache and your Django application. The tutorial provides the code.
• Configure Apache settings: Modify the Apache configuration file (/etc/apache2/sites-enabled/000-default.conf) to point to your wsgi.py script and handle static files.
• Restart Apache: sudo service apache2 restart to apply the changes.

Important Notes:

• The tutorial addresses potential issues like handling static files from Django packages and provides solutions for compatibility with different Django versions.
• The article emphasizes the importance of using a virtual environment (though not demonstrated in this specific deployment example) for better dependency management in more complex projects.

Conclusion and FAQs:

The article concludes with a comprehensive FAQ section addressing common questions about Django, mod_wsgi, deployment, troubleshooting, and security. It reinforces the advantages of using mod_wsgi for Django deployments and highlights its stability and integration with Apache.
