There is such a task. There is a website site.ru. it spins static through nginx and django through gunicorn.
It is necessary to create a test.site.ru subdomain so that, roughly speaking, the second site is spinning on it. I did the following: I
created two users: one for site.ru and the other for test.site.ru. created for each its own virtual environment. For each, I made my own settings file for nginx, installed each in a virtual environment via pip supervisor. The static and user files are in /var/www/project/public. In the management, where they provide me with a server, I made an entry test.site.ru A 111.222.333.444 ttl 30min, site.ru is spinning on the same ip. each user in the /home//etc folder has gunicorn settings for supervisord.
Here are all the settings
Main site site.ru:
nginx:

upstream project_server {
    server 127.0.0.1:8888 fail_timeout=0;
}

server {
    listen 80;

    rewrite ^/(.*) http://site.ru/$1 permanent;

        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_send_timeout 1000s;
        proxy_read_timeout 1000s; 

        if (!-f $request_filename) {
            proxy_pass http://project_server;
            break;
        }
    }

    location ~* ^.+\.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|rss|atom|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ {
        expires max;
    }

    error_page 500 502 503 504 /500.html;
    location = /500.html {
        root /var/www/project;
    }
}

gunicorn:

[program:gunicorn]

now settings for test.site.ru
nginx:

upstream test_project_server {
    server 127.0.0.1:8001 fail_timeout=0;
}

server {
    listen 80;
    server_name test.site.ru;

    large_client_header_buffers 8 32k;

    keepalive_timeout 5;

        if (!-f $request_filename) {
            proxy_pass http://test_project_server;
            break;
        }
    }

    error_page 500 502 503 504 /500.html;
    location = /500.html {
        root /var/www/project;
    }
}

gunicorn

command=/home/<user2>/.env/bin/gunicorn --workers=3 --worker-connections=1000 --worker-class=gunicorn.workers.ggevent.GeventWorker
 --bind=127.0.0.1:8001 project.wsgi:application --timeout=300 --graceful-timeout=10

environment=DJANGO_SETTINGS_MODULE="project.settings.test"
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/home/<user2>/log/gunicorn.log

The main site is fully functional.
The test one does not, it gives out 500.
There is also such a fact that when I delete the nginx config for the subdomain and restart nginx (service nginx restart), it says that * restarting nginx, and if I add the config, then it is silently executed... But the static on the test .site.ru works.
In general, I'm all confused and I don't even know where to dig ...

Answer 1

All in all, I solved the problem. Thanks for the tip sim3x .
It was all about the nginx configs, which, in principle, is logical.
In the config of the main site site.ru, I changed default to default_server. In principle, nothing has changed, because. there used to be a default directive, then it was replaced with default_server, but the behavior is the same.
But the second config was cut almost completely. I will give, then I will try to explain what mistakes were made.

upstream test_project_server {
    server 127.0.0.1:8001 fail_timeout=0;
}

server {
    listen 80;
    client_max_body_size 4G;
    server_name test.site.ru;
    access_log  /home/test_project/log/nginx_access.log;
    keepalive_timeout 5;

    root /var/www/project/public;

    error_page 500 502 503 504 /500.html;
    location = /500.html {
        root /var/www/project;
    }

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        if (!-f $request_filename) {
            proxy_pass http://test_project_server;
            break;
        }
     }
}

Two sections of the server were sawn out. Only one remained. This is done because there should be only one default_server in the configs, and if there are two servers in one config, he does not know which one to contact.
