[Solved]-How to run multiple Django sites on Nginx and uWSGI?

You can run multiple instances of uwsgi using Emperor Mode.

This handles the creation of new worker instances. These instances are brilliantly and hilariously named vassals. Each vassal just needs a config file which is usually placed (or symlinked) in /etc/uwsgi/vassals

For nginx you’ll need to create a server block for each host you wish to serve. Just change the server_name directive for each host you want to serve. Here’s an example:

#Simple HTTP server
server {
    listen   80; 
    root /usr/share/nginx/www;
    server_name host1.example.com;
}

#Django server
server {
    listen   80; 
    server_name host2.example.com;

    #...upstream config...
}

Important: Make sure you have specified your host names in /etc/hosts. I found that without doing this my django site was also served on the default server IP despite specifying that it should only be served on a specific host name within my nginx configuration.

I see many suggestions like @donturner’s answer. i.e. set two or more different server in nginx configure file. But the problem is each server needs an unique server_name either different domain name or sub-domain name. How about this kind of situation: I want to server two different Django project like this:

www.ourlab.cn/site1/  # first Django project
www.ourlab.cn/site2/  # second Django project

In this way, we can configure all of the settings in one server.

This is my setting in /etc/nginx/nginx.conf

# For more information on configuration, see:

user nginx;
worker_processes auto;

pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

}

This is my setting in /etc/nginx/conf.d/self_configure.conf

# /etc/nginx/conf.d/self_configure.conf
server {
    listen       80;
    server_name  www.ourlab.cn;

    # note that these lines are originally from the "location /" block
    root   /mnt/data/www/ourlab;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }
    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    # Django media
    location /media  {
        # your Django project's media files - amend as required
        alias /mnt/data/www/metCCS/metCCS/static/media;
    }

    location /static {
        # your Django project's static files - amend as required
        # first project's static files path
        alias /mnt/data/www/metCCS/metCCS/static/static_dirs;
    }
    location /static_lip {
        # second project's static files path
        alias /mnt/data/www/lipidCCS/lipidCCS/static/static_dirs;
    }

    # match www.ourlab.cn/metccs/*
    location ~* ^/metccs {
        include     uwsgi_params;
        uwsgi_pass  unix:/run/uwsgi/metCCS.sock;
    }
    # match www.ourlab.cn/lipidccs/*
    location ~* ^/lipidccs {
        include     uwsgi_params;
        uwsgi_pass  unix:/run/uwsgi/lipidCCS.sock;
    }
}

You also need to change one of the Django project’s settings.py file as STATIC_URL = '/static_lip/', so two projects can use their static files separately.

A new finding is nginx can server static files by itself. Even we close uwsgi and Django, we also can use these files through browser.
