将 ExpressJS 与 nginx 结合使用时出现 502 Bad Gateway

如果我像这样运行我的expressjs应用程序：coffee server.coffee并导航至localhost:8080，一切都很好。

但是，当我使用以下配置使用 nginx 反向代理 8080 时：

server {
    listen 0.0.0.0:80;
    server_name localhost;
    access_log /var/log/nginx/nodetest.log;

    location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy true;

      proxy_pass http://node/;
      proxy_redirect off;
    }
}

upstream node {
    server 127.0.0.1:8080;
}

我在 Chrome 开发控制台中收到以下错误：

GET http://184.73.217.204/socket.io/xhr-polling//1300750540040 502 (Bad Gateway)

以及 nginx 中的以下内容error.log

2011/03/22 13:07:59 [error] 10269#0: *18 upstream prematurely closed connection while
reading response header from upstream, client: 168.229.58.68, server: localhost, 
request:     "GET /socket.io/xhr-polling//1300799281533 HTTP/1.1", upstream:

referrer: "http://184.73.217.204/"

任何指导表示赞赏！

试试这个补丁...

    -proxy_pass http://node/;
    +proxy_pass http://node;
