How To Install Django 3 on Ubuntu 18.04

Introduction

Django is a high-level Python web framework that enables rapid development of secure and maintainable websites. It encourages clean, pragmatic design and provides a multitude of features to help developers build web applications efficiently.

This guide will walk you through the process of installing Django 3 on an Ubuntu 18.04 server. You will learn how to create a new Django project and run it on your server.

Prerequisites

Before you begin, ensure you have a non-root user with sudo privileges on your Ubuntu 18.04 server. If you haven't set this up yet, please follow an initial server setup guide to establish a user with the necessary permissions.

Main Steps

Global Install from Packages

If you prefer a straightforward installation method, you can install Django from the official Ubuntu repositories. However, note that the version may not be the latest available.

To update your local package index, run:

sudo apt update

Next, verify the Python version available on your system:

python3 -V

You should see output similar to:

Python 3.6.9

Now, you can install Django:

sudo apt install python3-django

To check if the installation was successful, run:

django-admin --version

The expected output will show the Django version installed:

3.0.0

Install with pip in a Virtual Environment

The recommended approach for installing Django is within a virtual environment. This allows you to manage dependencies for each project separately, mitigating conflicts.

Start by installing the necessary package:

sudo apt install python3-venv

Next, create a new directory for your Django project:

mkdir myproject && cd myproject

Create a virtual environment named venv:

python3 -m venv venv

Activate the virtual environment:

source venv/bin/activate

With the virtual environment activated, install Django using pip:

pip install django==3.0.0

To confirm Django was installed correctly, run:

django-admin --version

Advanced Configuration

After installing Django, it’s crucial to set up your project and development environment correctly for long-term sustainability and performance optimization.

Creating a New Django Project

To start a new Django project, use the django-admin command:

django-admin startproject myproject

Change into the project directory:

cd myproject

Run the development server to ensure everything is set up correctly:

python manage.py runserver

Visit http://127.0.0.1:8000 in your web browser to see your new Django project in action.

Database Configuration

Django uses SQLite by default, but for production, it’s advisable to use a more robust database such as PostgreSQL or MySQL. Update your settings in myproject/settings.py accordingly.

Best Practices

When working with Django, following best practices ensures your application is secure, maintainable, and efficient. Here are some recommendations:

• Always use a virtual environment to manage dependencies.
• Keep your Django version up to date for security and performance improvements.
• Use environment variables to store sensitive information such as secret keys and database credentials.
• Implement proper error handling and logging for better troubleshooting.
• Regularly back up your database and important data.

Troubleshooting

If you encounter issues during installation or while running your project, consider the following steps:

• Check the Python and Django installation version with python3 -V and django-admin --version.
• Ensure your virtual environment is activated before running your project.
• Review the error messages carefully; they often indicate what went wrong.
• Consult the Django documentation or community forums for additional guidance.

Conclusion

Installing Django 3 on Ubuntu 18.04 can significantly enhance your ability to develop powerful web applications. By following this guide, you should have a functional Django instance set up and ready for development.

Experiment with additional Django features and libraries to expand your skills and create innovative projects.
