centos nginx配置支持WebSocket(signalR)

Posted 2021-11-27 drek_blog

signalr 默认会调用websocket去连接集线器，centos下，用nginx默认设置不支持ws的

所以，必须更改配置，让nginx通过websocket

 server {
    listen 80;
    server_name admin.mu-booking.com; 
    location / {
        proxy_pass http://127.0.0.1:5000; 
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection upgrade;
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
    }

关键 

proxy_set_header Connection upgrade，
默认key-alive的，改成upgrade
