Nginx configuration domain name mapping

1. Support websockets

The same domain name, multiple ports, correspond to different services. For example, 9400 is http service, 1900 is websocket service.

Point 1: Configure multiple locations

server{
        listen 0.0.0.0:80;
        server_name test.com;

        location / {
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-Nginx-Proxy true;
            proxy_pass http://114.114.114.110:9400;
            proxy_redirect off;
          }
           location /mqtt {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_set_header X-Nginx-Proxy true;
                proxy_pass http://114.114.114.110:1900;
                proxy_redirect off;
            }
        }

Point 2: Upgrade http to websocket

http {
    map $http_upgrade $connection_upgrade {
          default upgrade;
          '' close;
    }

   ......

Modify the above location /mqtt

 location /mqtt {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Nginx-Proxy true;
        proxy_pass http://114.115.201.210:1900;
        proxy_redirect off;
  }

2. Port mapping

For example, nginx configures port 5001 service.

server {
        listen                          5001;
        client_max_body_size            100m;
        proxy_send_timeout              180s;
        proxy_read_timeout              600s;

        location / { ......
        }

        location ^~ /manage {
            proxy_pass                  http://127.0.0.1:5000;

             ......
        }

          location /node {
            proxy_pass                  http://127.0.0.1:5000;

             ......
        }
    
    }

Domain name access needs to be configured, mapped to port 80, configured in the same nginx.conf
     server {         listen 80;         server_name test.cn;         location / {                 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;                 proxy_set_header Host $http_host;                 proxy_pass http://114.114 .114.145:5001;                 proxy_redirect off;         }     }
