Install Django on Debian 9

Django is the most popular Python web framework designed to help developers build secure, scalable and maintainable web applications.

Django can be installed system-wide or in a Python virtual environment using pip. Django packages are included in the official Debian repositories and can be installed using the apt package manager. This is the easiest method to install Django on Debian 9, but not as flexible as installing in a virtual environment. Also, the version included in the repositories is always several releases behind the latest version of Django.

The main goal of Python virtual environments is to create an isolated environment for different Python projects. This way you can have multiple different Django environments on a single computer and install a specific version of a module on a per project basis without worrying that it will affect your other Django installations. If you install Django into the global environment then you can install only one Django version on your computer.

Installing Django on Debian 9

Perform the following steps to install Django in a Python virtual environment on Debian 9.

1. Installing Python 3 and venv

Debian 9 ships with Python 3.5 by default. You can verify that Python 3 is installed on your system by typing:

python3 -V

The output should look like this:

Python 3.5.3

The recommended way to create a virtual environment is by using the venv module.

The venv module is included in the python3-venv package. Install it by typing the following command:

sudo apt install python3-venv

Once the module is installed we are ready to create a virtual environment for our Django application.

2. Creating Virtual Environment

Start by navigating to the directory where you would like to store your Python 3 virtual environments. It can be your home directory or any other directory where your user has read and write permissions.

Create a new directory for your Django application and navigate into it:

mkdir my_django_appcd my_django_app

From inside the directory, execute the following command to create a new virtual environment:

python3 -m venv venv

The command above creates a directory called venv, which contains a copy of the Python binary, the Pip package manager , the standard Python library and other supporting files. You can use any name you want for the virtual environment.

To start using the virtual environment, activate it by running the activate script:

source venv/bin/activate

Once activated, the virtual environment’s bin directory will be added at the beginning of the $PATH variable. Also your shell’s prompt will change and it will show the name of the virtual environment you’re currently using. In our case that is venv.

3. Installing Django

Now that the virtual environment is active, install Django using the Python package manager pip:

pip install django
Within the virtual environment, you can use the command pip instead of pip3 and python instead of python3.

Verify the installation using the following command which will print the Django version:

python -m django --version

At the time of writing this article, the latest Django version is 2.1.2.


Your Django version may be different from the version shown here.

4. Creating a Django Project

Use the django-admin command-line utility to create a new Django project named mydjangoapp:

django-admin startproject mydjangoapp

The command above will create a mydjangoapp directory in your current directory.

tree  mydjangoapp/
`-- mydjangoapp

Inside that directory, you will find the main script for managing projects named and another directory including database configuration, and Django and application-specific settings.

Let’s migrate the database and create an administrative user.

First, navigate to the mydjangoapp directory:

cd mydjangoapp

SQLite is the default database for Django. For production applications, you can use PostgreSQL , MariaDB , Oracle or MySQL Database.

Migrate the database by typing:

python migrate

The output will look something like the following:

Operations to perform:
  Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
  Applying contenttypes.0001_initial... OK
  Applying auth.0001_initial... OK
  Applying admin.0001_initial... OK
  Applying admin.0002_logentry_remove_auto_add... OK
  Applying admin.0003_logentry_add_action_flag_choices... OK
  Applying contenttypes.0002_remove_content_type_name... OK
  Applying auth.0002_alter_permission_name_max_length... OK
  Applying auth.0003_alter_user_email_max_length... OK
  Applying auth.0004_alter_user_username_opts... OK
  Applying auth.0005_alter_user_last_login_null... OK
  Applying auth.0006_require_contenttypes_0002... OK
  Applying auth.0007_alter_validators_add_error_messages... OK
  Applying auth.0008_alter_user_username_max_length... OK
  Applying auth.0009_alter_user_last_name_max_length... OK
  Applying sessions.0001_initial... OK

Once the database is migrated, create an administrative user will be used to access the Django admin interface:

python createsuperuser

The command will prompt you for a username, an email address, and a password.

Username (leave blank to use 'linuxize'): admin
Email address:
Password (again):
Superuser created successfully.

5. Testing the Development Server

Start the development web server using the script followed by the runserver option:

python runserver

You’ll see the following output:

Performing system checks...

System check identified no issues (0 silenced).
October 20, 2018 - 11:16:28
Django version 2.1.2, using settings 'mydjangoapp.settings'
Starting development server at
Quit the server with CONTROL-C.
If you installed Django on a virtual machine and you want to access Django development server then you’ll need to edit the file and add the server IP address inside the ALLOWED_HOSTS list.

Open in your web browser and you will be presented with the default Django landing page:

Debian 9 django landing page

To access the Django admin interface, add /admin to the end of the URL ( This will take you to the admin login screen:

Debian 9 django login page

Enter your username and password and you will be redirected to the Django admin page:

Debian 9 django admin page

To stop the development server type CTRL-C in your terminal.

6. Deactivating the Virtual Environment

Once done with your work, deactivate the environment, by typing deactivate and you will return to your normal shell.



You have learned how to create a Python virtual environment and install Django on your Debian 9 system. To create additional Django development environments repeat the steps outlined in this tutorial.
