配置nginx作为websocket的代理

Question

我有一个websocket的应用程序，它位于:

http://localhost:8888/something/ws

我想使用nginx作为代理，但是连接的转发不起作用。这是我的配置文件:

upstream backend {
    server 127.0.0.1:8888;
}
server {
    listen 80;
    server_name localhost;
    location / {
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_pass http://backend;
        proxy_next_upstream error;
    }
    location /something/ws {
        proxy_pass http://backend;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

故障是什么?我需要重写路径吗?

Ubuntu 12.04。随nginx 1.1一起发布。在升级nginx到1.6之前，我不得不删除nginx-common和nginx-full，否则nginx 1.1将被重新安装…

您可以在下面尝试:

  location /something/ws/ {
            proxy_pass http://backend;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            # Path rewriting
            rewrite /something/ws/(.*) /$1 break;
            proxy_redirect off;
        }

关键是路径重写
