  1. Python (Django/Flask) Server Configuration

This article details configuring a MediaWiki server to effectively run Python web applications, specifically those built with the Django and Flask frameworks. This setup allows for dynamic content generation and integration with other Python-based services. It assumes you have a base MediaWiki installation functioning correctly.

Prerequisites

Before beginning, ensure the following are installed on your server:

  • Python 3.7 or higher: The core programming language.
  • pip: The Python package installer.
  • Virtualenv: A tool to create isolated Python environments.
  • A web server (e.g., Apache, Nginx) configured to proxy requests to your Python application.
  • Basic understanding of the command line interface.
  • MediaWiki 1.40 or higher is installed.

Setting up a Virtual Environment

Using a virtual environment is crucial for managing dependencies and avoiding conflicts.

1. Navigate to your desired project directory (e.g., `/var/www/python_apps`). 2. Create a virtual environment: 

   ```bash
   virtualenv venv
   ```

3. Activate the virtual environment: 

   ```bash
   source venv/bin/activate
   ```

   (Your prompt should now be prefixed with `(venv)`).

Django Configuration

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design.

1. Install Django: 

   ```bash
   pip install django
   ```

2. Create a Django project: 

   ```bash
   django-admin startproject myproject
   ```

3. Navigate into the project directory: 

   ```bash
   cd myproject
   ```

4. Run migrations: 

   ```bash
   python manage.py migrate
   ```

5. Configure your `settings.py` file. Pay attention to `ALLOWED_HOSTS` and `DATABASES` settings.

6. Run the development server (for testing – *not* for production): 

   ```bash
   python manage.py runserver 0.0.0.0:8000
   ```

   This starts a server listening on all interfaces (0.0.0.0) on port 8000.

Flask Configuration

Flask is a micro web framework written in Python. It is lightweight and flexible, suitable for smaller applications or APIs.

1. Install Flask: 

   ```bash
   pip install flask
   ```

2. Create a simple Flask application (e.g., `app.py`): 

   ```python
   from flask import Flask
   app = Flask(__name__)

   @app.route("/")
   def hello():
       return "Hello from Flask!"

   if __name__ == "__main__":
       app.run(debug=True, host='0.0.0.0')
   ```

3. Run the Flask application: 

   ```bash
   python app.py
   ```

   This starts a development server listening on port 5000.

1+ Core 2GB+ 10GB+ SSD 3.7+

Web Server Integration (Nginx Example)

To serve your Python application through a web server like Nginx, you need to configure a reverse proxy.

1. Create a new Nginx configuration file (e.g., `/etc/nginx/sites-available/myproject`): 

   ```nginx
   server {
       listen 80;
       server_name yourdomain.com;

       location / {
           proxy_pass http://127.0.0.1:8000; # For Django
           #proxy_pass http://127.0.0.1:5000; # For Flask
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
       }
   }
   ```

2. Create a symbolic link to enable the configuration: 

   ```bash
   sudo ln -s /etc/nginx/sites-available/myproject /etc/nginx/sites-enabled/
   ```

3. Test the Nginx configuration: 

   ```bash
   sudo nginx -t
   ```

4. Restart Nginx: 

   ```bash
   sudo systemctl restart nginx
   ```

Important Considerations

  • **Security:** Never run a production Django/Flask application with `debug=True`. Use a production-ready WSGI server like Gunicorn or uWSGI. Ensure proper security measures, including HTTPS, are in place.
  • **Database:** Django and Flask often require a database. PostgreSQL and MySQL are common choices. Configure your application to connect to the database.
  • **Static Files:** Properly serve static files (CSS, JavaScript, images) using your web server.
  • **Logging:** Implement comprehensive logging to monitor your application's health and troubleshoot issues. Logging best practices should be followed.
  • **MediaWiki Integration:** Develop extensions to integrate your Python application with MediaWiki. Consider using APIs or other communication methods.
  • **Monitoring:** Implement system monitoring to keep track of performance and resource usage.

Python Package Versions

Package Version
Django 4.2.7 Flask 2.3.2 Gunicorn 20.1.0 uWSGI 2.0.20 Virtualenv 20.24.2
