How to run multiple website on same Droplet that already host an active website?

Question

I’m quite new to backend and servers configurations.

I have a Django website already running using Nginx and Gunicorn and is successfully deployed to my Droplet.

I’m deciding to host multiple websites including test apps of different sorts i.e PHP, Wordpress, Laravel, Java supported backends, on the current droplet. But I don’t know exactly how to do it. I have some rough knowledge of Nginx Blocks. However I cannot dare to experiment with it because I’m afraid if something goes wrong my current running website would go down.

I don’t know how to do it? Will it affect my current website? How can I separate my current active website form all other process running in my Droplet?

Any help will be appreciated and also I would love to refer me to some tutorials and references so I can achieve what I want.

Note: I’m running Ubuntu 18.04 on my Droplet.

Thanks

Hello, As you already have Nginx installed, what you could do is to use separate Nginx Server Blocks for each of your websites. You can follow the steps here on how to do that: https://www.digitalocean.com/community/tutorials/how-to-set-up-nginx-server-blocks-virtual-hosts-on-ubuntu-16-04 For PHP you could follow the steps here on how to install it on your server, you can skip the Nginx installation step as you already have this installed: https://www.digitalocean.com/community/tutorials/how-to-install-linux-nginx-mysql-php-lemp-stack-ubuntu-18-04 Hope that this helps.Regards,Bobby

Configuring multiple Django projects on a single DigitalOcean droplet using Nginx as a reverse proxy involves several key steps, including setting up Nginx server blocks (similar to virtual hosts in Apache) and managing Django project settings for production. Here’s a comprehensive step-by-step guide on how to do this: Step 1: Prepare the Droplet Create a Droplet : If you haven’t already, create a DigitalOcean Droplet with a Linux distribution like Ubuntu. SSH into your Droplet : bashCopy code ssh root@your_droplet_ip Update your system : bashCopy code sudo apt update && sudo apt upgrade Step 2: Install Dependencies Install Python, pip, and other necessary packages : sudo apt install python3-pip python3-dev libpq-dev postgresql postgresql-contrib nginx curl git Install and set up virtual environments for Python to isolate project dependencies: sudo apt install python3-venv Step 3: Set Up Your Django Projects For each Django project: Create a project directory : mkdir /var/www/project1 cd /var/www/project1 Create and activate a virtual environment : python3 -m venv venv source venv/bin/activate Install Django and other dependencies (make sure to have a requirements.txt): pip install django gunicorn psycopg2-binary Configure your Django project settings to connect to the database and manage static and media files correctly. Collect static files : python manage.py collectstatic Create a Gunicorn systemd service file for each project to handle the application server. Example for project1: sudo nano /etc/systemd/system/project1_gunicorn.service Add the following configuration: [Unit] Description=gunicorn daemon for project1 After=network.target [Service] User=root Group=www-data WorkingDirectory=/var/www/project1 ExecStart=/var/www/project1/venv/bin/gunicorn --workers 3 --bind unix:/var/www/project1/project1.sock project1.wsgi:application [Install] WantedBy=multi-user.target Start and enable the service : sudo systemctl start project1_gunicorn sudo systemctl enable project1_gunicorn Step 4: Configure Nginx as a Reverse Proxy Create a Nginx server block for each project : sudo nano /etc/nginx/sites-available/project1 Example configuration for project1: server { listen 80; server_name project1.domain.com; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /var/www/project1; } location / { include proxy_params; proxy_pass http://unix:/var/www/project1/project1.sock; } } Enable the Nginx server block by linking it to the sites-enabled directory: sudo ln -s /etc/nginx/sites-available/project1 /etc/nginx/sites-enabled Test the Nginx configuration and restart Nginx : sudo nginx -t sudo systemctl restart nginx Repeat for each additional Django project, ensuring you use unique socket files and server names. Step 5: Secure Your Server Set up a firewall (e.g., using UFW): sudo ufw allow 'Nginx Full' sudo ufw allow ssh sudo ufw enable Add SSL certificates using Let’s Encrypt for secure HTTPS connections: sudo apt install certbot python3-certbot-nginx sudo certbot --nginx -d project1.domain.com Final Steps Double-check all configurations to ensure there are no conflicts between server blocks. Regularly update your system and Django applications for security and stability. By following these steps, you can efficiently run multiple Django projects on a single DigitalOcean droplet, each accessible via its unique domain and securely handled by Nginx as a reverse proxy.
