nginx：[警告] 0.0.0.0:80 上的服务器名称“域”冲突，忽略

Question

I've bought a domain name, deployed my django application to DigitalOcean, but this error doesn't let me use application. How can I ignore this error ? Here are my codes:

setting.py:

ALLOWED_HOSTS = ['blablabla.com', '64.225.12.157']

nginx:

server {
    listen 80;
    server_name blablabla.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/sammy/myproject;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/sammy/myproject/myproject.sock;
    }
}

default nginx:

        root /var/www/blablabla.com;

        index index.html index.htm index.nginx-debian.html;

        server_name blablabla.com;

        location / {
                try_files $uri $uri/ =404;
        }

Answer 1

You have two issues (the second one is mostly a recommendation):

---

First:

You've defined the server_name directive in two places -- one in the default http block and one in a server block. Drop the reference in the default http block and keep only the one at the server block. Also unless you know what you're doing, drop the location / directive from http block as well, the locations are usually put in the server block to do URL mappings for that server. Putting that in http block does the mapping globally, which causes a headache while tracking the mapping down while debugging.

Second:

Django talks the WSGI protocol, so (in production) a WSGI server is needed to send request and get response back from Django. Presumably, you're using one given by the reference to the UNIX domain socket:

/home/sammy/myproject/myproject.sock

So if your WSGI server (eg uWSGI , gunicorn ) listens on that socket for incoming requests, and also send the response via that, you need to tell Nginx to use WSGI protocol to send-retrieve data from the socket and also pass relevant WSGI parameters. An example of this would be:

upstream foobar {
    server unix:///home/sammy/myproject/myproject.sock;
}

server {
    server_name blablabla.com;
    ...
    ...
    location / {
        uwsgi_pass foobar;
        include /etc/nginx/uwsgi_params;
    }
}

Your current configuration with reverse proxying via proxy_pass will work but using WSGI gets you closer to the underlying protocol used by underlying layers hence is recommended.
