squid后面的nginx如果有proxy_pass的話會(huì)504?

把nginx放到了squid后面，一般的server都沒(méi)有問(wèn)題，有一個(gè)server里面使用了proxy mod，這時(shí)通過(guò)squid訪問(wèn)proxy過(guò)得url就會(huì)504，而直接訪問(wèn)沒(méi)有問(wèn)題，具體描述:

1.nginx配置

server {
  listen   192.168.0.10:80;
  server_name  tech.test.com;
  proxy_next_upstream error;

  location = /data/js/config.js {
      root              /opt/tmp/test;
  }

  location /news {
      proxy_pass        http://news.test.net;
      proxy_redirect           off;
      proxy_set_header         Host $host;
      proxy_set_header         X-Real-IP $remote_addr;
      proxy_set_header         X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

起來(lái)后直接訪問(wèn)http://tech.test.com/data/js/config.js和http://tech.test.com/news/xx.html沒(méi)有問(wèn)題

2.前面加上一個(gè)squid,通過(guò)squid訪問(wèn)http://tech.test.com/data/js/config.js沒(méi)有問(wèn)題，訪問(wèn)http://tech.test.com/news/xx.html就會(huì) 504 gateway timeout，nginx錯(cuò)誤日志:

1. 2008/09/23 08:58:43 [error] 17645#0: *1 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 127.0.0.1, server: tech.test.com, request: "GET /news/2008/0912/16357.html HTTP/1.0", upstream: "http://192.168.0.16:80/news/2008/0912/16357.html", host: "tech.test.com"

復(fù)制代碼

怎么解決呢？謝謝
