javascript - 结合使用ExpressJS和Nginx时的502错误网关

如果我这样运行我的expressjs应用程序:coffee server.coffee并导航到localhost:8080，一切正常。

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开发者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的error.log中的以下内容

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,

referrer: "http://184.73.217.204/"

任何指导表示赞赏!

最佳答案

试试这个补丁...

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