Setting Up Django for Production Using Gunicorn on Linux.

Fun Fact: Why do Java developers wear glasses? Because they don’t see sharp!

Django is a popular web framework for building web applications in Python. While the built-in development server is handy for testing your Django application during development, it’s not suitable for production use. For production, you should use a production-ready web server like Gunicorn and manage it using systemd.

Prerequisites

• Python 3 installed on your server.
• A Django project ready for production deployment.
• Virtual environment.

1: Install Gunicorn:-

Inside your virtual environment, install Django and Gunicorn:

pip install gunicorn

Enter fullscreen mode Exit fullscreen mode

2: Configure Gunicorn :-

Create a Gunicorn configuration file for your Django project. In your project directory, create a file named gunicorn_config.py and add the following content, customizing it to your project:

import multiprocessing

bind = "127.0.0.1:8000"  # Replace with your desired IP and port workers = multiprocessing.cpu_count() * 2 + 1
worker_class = "gthread"
threads = 2
timeout = 60

Enter fullscreen mode Exit fullscreen mode

2: Test Gunicorn :-

Test Gunicorn to ensure it can serve your Django application. Run the following command from your project directory, replacing myproject with your Django project’s name:

gunicorn -c gunicorn_config.py myproject.wsgi

Enter fullscreen mode Exit fullscreen mode

If Gunicorn starts without errors, it’s working correctly. You can stop it by pressing Ctrl + C.
Boom! Gunicorn is now part of our family.

3: Create a systemd Service :-

Create a systemd service file to manage the Gunicorn process. Use a text editor to create a file named myproject_gunicorn.service in the /etc/systemd/system/ directory:

sudo nano /etc/systemd/system/myproject_gunicorn.service

Enter fullscreen mode Exit fullscreen mode

Add the following content to the file, adjusting the paths and configuration as needed:

[Unit]
Description=Gunicorn daemon for myproject
After=network.target

[Service]
User=your_username
Group=your_group
WorkingDirectory=/path/to/your/project
ExecStart=/path/to/your/virtualenv/bin/gunicorn -c gunicorn_config.py myproject.wsgi
Restart=always

[Install]
WantedBy=multi-user.target

Enter fullscreen mode Exit fullscreen mode

Replace your_username, your_group, /path/to/your/project, and /path/to/your/virtualenv with your actual information.

Save and exit the text editor.

4: Enable and Start the systemd Service :-

Enable the systemd service and start Gunicorn:

sudo systemctl enable myproject_gunicorn
sudo systemctl start myproject_gunicorn

Enter fullscreen mode Exit fullscreen mode

Check the status of the Gunicorn service to make sure it’s running without errors:

sudo systemctl status myproject_gunicorn

Enter fullscreen mode Exit fullscreen mode

If everything is configured correctly, your Django application should now be running in production using Gunicorn and managed by systemd. You can access it through the specified IP and port. Make sure to configure your web server (e.g., Nginx or Apache) as a reverse proxy to forward requests to Gunicorn for better security and performance in a production environment.

Until next time, keep coding and keep smiling, because development is all about making the magic happen!
Happy coding!!!
