Run multiple django project with nginx and gunicorn

Question

I am using Ubuntu 18 servers and using nginx with gunicorn I follow Digitalocean tutorial for server setup. I successfully did for one project but now I need to run multiple projects under by server.

Here is my gunicorn setup

command:

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

file:

[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

[Service]
User=rfr
Group=www-data
WorkingDirectory=/home/rfr/helpdesk/helpdesk
ExecStart=/home/rfr/helpdesk/env/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/gunicorn.sock \
          helpdesk.wsgi:application


[Install]
WantedBy=multi-user.target

And also here is my nginx setup

command:

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

file:

server {
    listen 80;
    server_name 192.168.11.252;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /assets/ {
        root /home/rfr/helpdesk/helpdesk;
    }

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

Now how can I add another project under the following IP? I want to configure my nginx setup for access project like this

192.168.11.252/firstProject

192.168.11.252/secoundproject

I try a few googles but not help me more.

You use a proxy_pass with two different sockets. Setup gunicorn on the first project to listen on a socket called first_project.sock, and setup gunicorn on the second project to listen on a socket called second_project.sock.

gunicorn for first project

[Unit]
Description=gunicorn for firstProject
Requires=gunicorn.socket
After=network.target

[Service]
User=rfr
Group=www-data
WorkingDirectory=/home/rfr/first_project/first_project
ExecStart=/home/rfr/first_project/env/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/first_project.sock \
          first_project.wsgi:application


[Install]
WantedBy=multi-user.target

gunicorn for second project

[Unit]
Description=gunicorn for secondProject
Requires=gunicorn.socket
After=network.target

[Service]
User=rfr
Group=www-data
WorkingDirectory=/home/rfr/second_project/second_project
ExecStart=/home/rfr/second_project/env/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/second_project.sock \
          second_project.wsgi:application
[Install]
WantedBy=multi-user.target

nginx configuration

server {
    listen 80;
    server_name 192.168.11.252;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /firstProject/assets/ {
        root /home/rfr/first_project/first_project;
    }
    location /secondProject/assets/ {
        root /home/rfr/second_project/second_project;
    }

    location /firstProject {
        include proxy_params;
        rewrite /firstProject(.*) $1;
        proxy_pass http://unix:/run/first_project.sock;
    }

    location /secondProject {
        include proxy_params;
        rewrite /secondProject(.*) $1;
        proxy_pass http://unix:/run/second_project.sock;

    }
}

The heavy lifting here is by the nginx rewrite directive which will let your app think of the url as everything after firstProject or secondProject in the url.
