How To Install Python & Django on Debian 10 / Debian 9

Welcome to our guide on how to Install Python & Django on Debian 10 / Debian 9 Linux system. Django is a widely used open source Web framework for Python. It is designed to encourage rapid Web development without complexities and prior knowledge of many technologies. This article will discuss the steps to install Django on Debian 10 (Buster) Linux distribution.

Step 1: Install Pip on Debian

Pip Python package manager will be used to install Django on Debian 10. Since Pip is not pre-installed on Debian 10, refer to our guide below on installation.

Step 2: Install Django on Debian 10 / Debian 9

The easiest and quickest way to install Django on Debian 10 Linux is with Pip. This can be pip2 for Python 2 or pip3 for Python 3.

Let’s first check our Python and Pip version

# Python 3 users
$ python3 -V
Python 3.7.3
$ pip3 -V
pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)

# Python 2 users
$ python2 --version
Python 2.7.16
$ pip2 --version
pip 18.1 from /usr/lib/python2.7/dist-packages/pip (python 2.7)

Download and install Django on Debian.

Python 3

# In user space
pip3 install --user Django

# Globally
sudo pip3 install Django

Python 2

# In user space
pip2 install --user Django

# Globally
sudo pip2 install Django

The installation of Django will give you django-admin command to manage Projects,

$ which django-admin
~/.local/bin/django-admin

# For Global installation
$ which django-admin
/usr/local/bin/django-admin

If ~/.local/bin/ is not in your PATH, add it like below:

$ nano ~/.bashrc

Add:

export PATH=$PATH:~/.local/bin/

Source the bashrc file

$ source ~/.bashrc

Check django-admin version using:

$ django-admin --version
2.2.6

Step 3: Create a test Django Application

Note: In the next sections we’re using Python 3 for all illustrations.

Create a Django test application by running

mkdir projects && cd projects
django-admin startproject test_app
cd test_app

test_app is the name of our Django Project.

Apply pending migrations

$ python3 manage.py migrate
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

Step 4: Create an Admin Account

Create a Django project superuser account by running the following commands from your Django application directory.

$ python3 manage.py createsuperuser
Username (leave blank to use 'jmutai'): admin
Email address: [email protected]
Password: 
Password (again): 
Superuser created successfully.

Input your admin username, email address, and password.

Step 5: Allow external access to the Django web application (Optional)

Note that by default Django doesn’t allow external access to the application, you need to explicitly define an ACL.

$ nano test_app/settings.py

Edit the lineALLOWED_HOSTS to whitelist your Computer IP or LAN subnet.

ALLOWED_HOSTS = ['192.168.18.50']

You can now  start Django application server:

$ python3 manage.py runserver 0.0.0.0:8080
Watching for file changes with StatReloader
Performing system checks...

Django version 2.2.6, using settings 'test_app.settings'
Starting development server at http://0.0.0.0:8080/
Quit the server with CONTROL-C.

If you open the URL http://[server IP/hostname]:8080 you should see a successful message like below:

Django Administration page is available on :8080/admin

Login with created username and password:

The admin page allows you to add other users, add groups, change password e.t.c. It looks like below:
