使用 nginx 和 gunicorn 运行多个 django 项目

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.

  
 
  
  

[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

  
 
  
  

  
 
  
  

[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

  
 
  
  

  
 
  
  

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.

It worked for me with this config:

1. sudo nano /etc/systemd/system/firstsite.socket

    [Unit]
    Description=firstsite socket
    
    [Socket]
    ListenStream=/run/firstsite.sock
    
    [Install]
    WantedBy=sockets.target

2. sudo nano /etc/systemd/system/secondsite.socket

    [Unit]
    Description=secondsite socket
    
    [Socket]
    ListenStream=/run/secondsite.sock
    
    [Install]
    WantedBy=sockets.target

3. sudo nano /etc/systemd/system/firstsite.service

    [Unit]
    Description=gunicorn daemon
    Requires=firstsite.socket
    After=network.target
    
    [Service]
    User=non-root-user
    Group=www-data
    WorkingDirectory=/home/non-root-user/firstsite/
    ExecStart=/home/non-root-user/firstsite/env/bin/gunicorn \
    --access-logfile - \
    --workers 3 \
    --bind unix:/run/firstsite.sock \
    firstsite.wsgi:application
    
    [Install]
    WantedBy=multi-user.target

4. sudo nano /etc/systemd/system/secondsite.service
    [Unit]
    Description=gunicorn daemon
    Requires=secondsite.socket
    After=network.target
    
    [Service]
    User=non-root-user
    Group=www-data
    WorkingDirectory=/home/non-root-user/secondsite/
    ExecStart=/home/non-root-user/secondsite/env/bin/gunicorn \
    --access-logfile - \
    --workers 3 \
    --bind unix:/run/secondsite.sock \
    secondsite.wsgi:application
    
    [Install]
    WantedBy=multi-user.target

5. NGINX firstsite.ru

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


6. NGINX secondsite.ru


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


sudo systemctl start firstsite.socket
sudo systemctl enable firstsite.socket
sudo systemctl status firstsite.socket
sudo systemctl restart firstsite

sudo systemctl start secondsite.socket
sudo systemctl enable secondsite.socket
sudo systemctl status secondsite.socket
sudo systemctl restart secondsite
