How to install Django on Ubuntu 20.04 | How to install Django

To install Django on Ubuntu 20.04 with Nginx as a reverse proxy, you'll need to follow these steps:

1. Update the system packages:

   sudo apt update

   sudo apt upgrade

   

2. Install pip (Python package installer) and other dependencies:

  

sudo apt install python3-pip python3-dev libpq-dev nginx

3. Create a Python virtual environment for your Django project:

   sudo apt install python3-venv

   mkdir ~/myproject

   cd ~/myproject

   python3 -m venv myprojectenv

4. Activate the virtual environment:

   source myprojectenv/bin/activate

5. Install Django and Gunicorn (a WSGI HTTP server for running Django applications):

   pip install django gunicorn

   

6. Start a new Django project:

   django-admin startproject myproject

   

7. Configure Django to use a PostgreSQL database (optional):

   - Install PostgreSQL and its dependencies:

  

     sudo apt install postgresql postgresql-contrib

  

   - Create a new PostgreSQL database and user:

       sudo -u postgres psql

     CREATE DATABASE myprojectdb;

     CREATE USER myprojectuser WITH PASSWORD 'password';

     GRANT ALL PRIVILEGES ON DATABASE myprojectdb TO myprojectuser;

     \q

     

   - Update the database settings in the Django project's `settings.py` file:

      cd myproject

     nano settings.py

     

     Update the following settings:

          DATABASES = {

         'default': {

             'ENGINE': 'django.db.backends.postgresql_psycopg2',

             'NAME': 'myprojectdb',

             'USER': 'myprojectuser',

             'PASSWORD': 'password',

             'HOST': 'localhost',

             'PORT': '',

         }

     }

     

8. Collect the static files for your Django project:

  python manage.py collectstatic

 

9. Test your Django project by running the development server:

 

   python manage.py runserver

   Visit http://localhost:8000 in your web browser to see if the Django application is working correctly. Press `Ctrl + C` to stop the development server.

10. Configure Nginx as a reverse proxy:

    - Create a new Nginx configuration file:

     

      sudo nano /etc/nginx/sites-available/myproject

     

    - Add the following configuration (replace `your_domain` with your actual domain name or IP address):

     

      server {

          listen 80;

          server_name your_domain;

          location / {

              proxy_pass http://localhost:8000;

              proxy_set_header Host $host;

              proxy_set_header X-Real-IP $remote_addr;

              proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

              proxy_set_header X-Forwarded-Proto $scheme;

          }

      }

     

    - Enable the Nginx site:

     

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

      

    - Test the Nginx configuration:

     

       sudo nginx -t

      

    - Restart Nginx:

      

       sudo systemctl restart nginx

      

11. Access your Django application through the Nginx reverse proxy. Visit `http://your_domain` in your web browser, and you should see your Django application running.

That's it! You have successfully installed Django on Ubuntu 20.04 with Nginx as a reverse proxy
