In this blog, I am going to show you how to simply setup Django application on Cloudpanel 2 with Gunicorn and nginx

This tutorial is aimed at the Django user who wants to set up a production web server. It takes you through the steps required to set up Django so that it works nicely with Gunicorn and nginx. It covers all three components, providing a complete stack of web application and server software.

CloudPanel is a free software to configure and manage a server with an obsessive focus on simplicity.
Run static websites, PHP, Node.js and, Python applications.

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

nginx (pronounced engine-x) is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server.

Gunicorn, short for Green Unicorn, is a popular WSGI (Web Server Gateway Interface) HTTP server for running Python web applications. It’s a lightweight and production-ready server that can serve web applications built on frameworks like Flask, Django, and others.

Using Gunicorn is a common practice when deploying Python web applications, and it’s often part of the deployment stack alongside other tools like Nginx or Apache.

  1. First go to your Cloudpanel Hosting, then go to Add site

2. Create a Python site

3. Add and note details given below:

1) Domain name –

2) App port – 8090

3) Site User – tutorialslides

Now click on Create

4. Now install SSL Let’s Encrypt Certificate

5. Log in via SSH with the Root User and go to the directory: Use Filezilla or Else use Cloudpanel  Filemanager to upload all your Django files except env or Venv folder

Now go to domain settings and copy directory path

Now login to SSH and let’s install Django and create venv

					cd /home/tutorialslides/htdocs/


The below code will create a virtual environment called ENV 

					python -m venv env
# or 
python3 -m venv env

Now activate ENV using below code

					source env/bin/activate

If you see your terminal like this. then your ENV is running properly


Now install requirements.txt file

					pip install -r requirements.txt
Now install  Django Gunicorn
					pip install django gunicorn psycopg2-binary

Now migrate your Django database for the first time. 

					django makemigrations
django migrate

If you followed the initial server setup guide, you should have a UFW firewall protecting your server. In order to test the development server, we’ll have to allow access to the port we’ll be using.

Create an exception for port 8000 by typing:

					sudo ufw allow 8000

Finally, you can test our your project by starting up the Django development server with this command:


In your web browser, visit your server’s domain name or IP address followed by :8000:


You should receive the default Django index page or your project page.

Creating systemd Socket and Service Files for Gunicorn

We have tested that Gunicorn can interact with our Django application, but we should implement a more robust way of starting and stopping the application server. To accomplish this, we’ll make systemd service and socket files.

The Gunicorn socket will be created at boot and will listen for connections. When a connection occurs, systemd will automatically start the Gunicorn process to handle the connection.

Start by creating and opening a systemd socket file for Gunicorn with sudo privileges:

					sudo nano /etc/systemd/system/gunicorn.socket

Inside, we will create a [Unit] section to describe the socket, a [Socket] section to define the socket location, and an [Install] section to make sure the socket is created at the right time: and paste below code.

Description=gunicorn socket



Save and close the file when you are finished.

Next, create and open a systemd service file for Gunicorn with sudo privileges in your text editor. The service filename should match the socket filename with the exception of the extension:

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

Save and close the file when you are finished.

Next, create and open a systemd service file for Gunicorn with sudo privileges in your text editor. The service filename should match the socket filename with the exception of the extension:

Note: Replace user= tutorialslides with your site user id and replace with your domain

Description=gunicorn daemon

ExecStart=/home/tutorialslides/htdocs/ \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/gunicorn.sock \


With that, our systemd service file is complete. Save and close it now.

We can now start and enable the Gunicorn socket. This will create the socket file at /run/gunicorn.sock now and at boot. When a connection is made to that socket, systemd will automatically start the gunicorn.service to handle it:

					sudo systemctl start gunicorn.socket
sudo systemctl enable gunicorn.socket
Checking for the Gunicorn Socket File

Check the status of the process to find out whether it was able to start:

					sudo systemctl status gunicorn.socket

You should receive an output like this:

‚óŹ gunicorn.socket - gunicorn socket
     Loaded: loaded (/etc/systemd/system/gunicorn.socket; enabled; vendor prese>
     Active: active (listening) since Fri 2020-06-26 17:53:10 UTC; 14s ago
   Triggers: ‚óŹ gunicorn.service
     Listen: /run/gunicorn.sock (Stream)
      Tasks: 0 (limit: 1137)
     Memory: 0B
     CGroup: /system.slice/gunicorn.socket

Go to your cloudpanel sites settings page > vhost

Replace with below code on vhost

					server {
  listen 80;
  listen [::]:80;
  listen 443 ssl http2;
  listen [::]:443 ssl http2;


  if ($scheme != "https") {
    rewrite ^ https://$host$uri permanent;

  location ~ /.well-known {
    auth_basic off;
    allow all;
 location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/tutorialslides/htdocs/;


  index index.html;

 location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;

  #location ~* ^.+\.(css|js|jpg|jpeg|gif|png|ico|gz|svg|svgz|ttf|otf|woff|woff2|eot|mp4|ogg|ogv|webm|webp|zip|swf)$ {
  #  add_header Access-Control-Allow-Origin "*";
  #  expires max;
  #  access_log on;

  if (-f $request_filename) {

If no errors are reported, go ahead and restart Nginx by typing:

					sudo systemctl restart nginx
sudo ufw delete allow 8000
sudo ufw allow 'Nginx Full'
					sudo systemctl status nginx
#If problem exist

sudo systemctl start nginx
sudo systemctl status nginx

					sudo systemctl daemon-reload
sudo systemctl restart gunicorn.socket gunicorn.service

Done. Now you can refresh your domain your site will be up and running.
