Hosting a Django App and WordPress Site on the Same VPS with Nginx: A Comprehensive Guide
As a software developer or web administrator, you may find yourself in a situation where you need to host multiple web applications on the same server. This could be the case if you have a Django-based web application and a WordPress-powered website, for example. Hosting these applications on separate servers can be costly and resource-intensive, so a more efficient solution is to run them on the same Virtual Private Server (VPS) with Nginx as the reverse proxy.
In this comprehensive guide, we'll walk you through the process of setting up a Django app and a WordPress site on the same VPS with Nginx. We'll cover the necessary configurations, best practices, and troubleshooting tips to ensure your setup is secure, scalable, and performant.
Understanding the Architecture
Before we dive into the implementation, let's first understand the overall architecture of this setup. The main components are:
- VPS: The Virtual Private Server that will host both the Django app and the WordPress site.
- Nginx: The web server that will act as the reverse proxy, handling incoming requests and forwarding them to the appropriate application.
- Django: The Python-based web framework that powers your application.
- WordPress: The popular content management system that will host your website.
The general flow of a user's request in this setup would be:
- The user's browser sends a request to your domain.
- Nginx receives the request and determines whether it should be forwarded to the Django app or the WordPress site based on the requested URL.
- If the request is for the Django app, Nginx will forward it to the Gunicorn application server, which will handle the request and send the response back to Nginx.
- If the request is for the WordPress site, Nginx will forward it directly to the WordPress application.
- Nginx will then return the final response to the user's browser.
By using Nginx as the reverse proxy, you can efficiently manage and load-balance both applications on the same server, ensuring optimal performance and scalability.
Prerequisites
Before we begin, ensure that you have the following prerequisites in place:
- VPS: You should have a VPS (Virtual Private Server) with a clean installation of Ubuntu 20.04 or a similar Linux distribution.
- Nginx: Nginx should be installed and configured on your VPS.
- Django: Your Django application should be set up and ready to be deployed.
- WordPress: You should have a WordPress site ready to be hosted.
If you need guidance on setting up any of these components, you can refer to the following resources:
Once you have these prerequisites in place, you can proceed with the setup.
Configuring Nginx
The first step is to configure Nginx to handle the incoming requests and forward them to the appropriate application.
-
Create Nginx Configuration Files: Create two separate configuration files for your Django app and WordPress site. You can do this by creating new files in the /etc/nginx/sites-available/
directory.
- For the Django app, create a file named
django.conf
.
- For the WordPress site, create a file named
wordpress.conf
.
-
Configure the Django App: In the django.conf
file, add the following configuration:
server {
listen 80;
server_name your_django_domain.com;
location / {
proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
This configuration tells Nginx to listen for incoming requests on port 80 (HTTP) and forward them to the Django application running on 127.0.0.1:8000
(the Gunicorn application server).
-
Configure the WordPress Site: In the wordpress.conf
file, add the following configuration:
server {
listen 80;
server_name your_wordpress_domain.com;
root /var/www/html/wordpress;
index index.php;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
access_log off;
}
}
This configuration tells Nginx to listen for incoming requests on port 80 (HTTP) and forward them to the WordPress application located in the /var/www/html/wordpress
directory.
-
Enable the Configuration Files: Create symlinks for the configuration files in the /etc/nginx/sites-enabled/
directory to enable them:
sudo ln -s /etc/nginx/sites-available/django.conf /etc/nginx/sites-enabled/
sudo ln -s /etc/nginx/sites-available/wordpress.conf /etc/nginx/sites-enabled/
-
Restart Nginx: After making the changes, restart Nginx to apply the new configurations:
sudo systemctl restart nginx
With this Nginx configuration in place, your Django app and WordPress site will be accessible through their respective domains.
Deploying the Django App
Now that Nginx is set up, you can proceed with deploying your Django application. The process will vary depending on your Django setup, but in general, you should follow these steps:
-
Install Dependencies: Ensure that you have all the necessary dependencies installed, including Python, Django, and any other required packages.
-
Configure Gunicorn: Set up Gunicorn as the application server for your Django app. Create a Gunicorn systemd service file and configure it to start your Django app.
-
Configure Nginx: In the django.conf
Nginx configuration file, update the proxy_pass
directive to point to the Gunicorn application server.
-
Restart Services: Restart both Nginx and the Gunicorn service to apply the changes.
For detailed instructions on setting up Django with Gunicorn and Nginx, you can refer to the DigitalOcean tutorial mentioned earlier.
Deploying WordPress
Deploying WordPress on the same VPS with Nginx is relatively straightforward. Here are the steps:
-
Install WordPress: Download and extract the latest version of WordPress to the /var/www/html/wordpress
directory.
-
Configure WordPress: Follow the standard WordPress installation process by accessing your WordPress domain in a web browser and completing the setup wizard.
-
Configure Nginx: In the wordpress.conf
Nginx configuration file, ensure that the root
directive points to the correct WordPress installation directory (/var/www/html/wordpress
).
-
Restart Nginx: Restart Nginx to apply the changes.
After completing these steps, your WordPress site should be accessible through the configured domain.

Best Practices and Considerations
To ensure the optimal performance and security of your setup, consider the following best practices:
-
SSL/HTTPS Configuration: It's recommended to configure SSL/HTTPS for both your Django app and WordPress site to secure the connections. You can use Let's Encrypt or purchase SSL certificates and configure Nginx accordingly.
-
Separate Domains: Use separate domains for your Django app and WordPress site to maintain a clear separation and avoid potential conflicts.
-
Resource Isolation: Ensure that your Django app and WordPress site are isolated from each other in terms of resources, such as database connections, file storage, and caching. This will prevent one application from impacting the other.
-
Monitoring and Logging: Set up monitoring and logging mechanisms to track the performance and health of both applications, as well as any potential security incidents.
-
Automated Backups: Implement a reliable backup strategy to regularly back up your Django app and WordPress site data, including the database and file storage.
-
Regular Updates and Patches: Keep your Django, WordPress, Nginx, and other software components up-to-date with the latest security patches and bug fixes to maintain the overall system's integrity.
-
Security Hardening: Implement security best practices, such as strong password policies, firewall configuration, and user access management, to protect your VPS and the hosted applications.
By following these best practices, you can ensure that your Django app and WordPress site running on the same VPS with Nginx are secure, scalable, and performant.
Troubleshooting and Support
If you encounter any issues during the setup or operation of your Django app and WordPress site on the same VPS with Nginx, consider the following troubleshooting steps:
-
