你知道是怎么回事吗？

经过几个小时的调试，下面是我是怎么做的：

使用Ubuntu 12.04、Nginx和php5-fmp

请检查您的日志文件！日志文件是你的朋友。504网关问题意味着我的服务器与网站通信不正常。因此，在我的例子中，我有Nginx和php-fpm来管理请求。我必须检查2个日志文件：

/var/log/nginx/error.log和/var/log/php5-fpm.log

在error.log中：

recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 76.66.174.147, server: xxxxxxx.com, request: "GET /wp-admin/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.xxxxxxx.com"

在php5-fpm.log中：

netstat | grep 9000
tcp        0      0 localhost.localdom:9000 localhost.localdo:58424 SYN_RECV   
tcp      913      0 localhost.localdom:9000 localhost.localdo:57917 CLOSE_WAIT 
tcp      857      0 localhost.localdom:9000 localhost.localdo:58032 CLOSE_WAIT 
tcp     1633      0 localhost.localdom:9000 localhost.localdo:58395 CLOSE_WAIT 
tcp      961      0 localhost.localdom:9000 localhost.localdo:58025 CLOSE_WAIT 
tcp      857      0 localhost.localdom:9000 localhost.localdo:58040 CLOSE_WAIT 
tcp      953      0 localhost.localdom:9000 localhost.localdo:58005 CLOSE_WAIT 
tcp      761      0 localhost.localdom:9000 localhost.localdo:58016 CLOSE_WAIT 
tcp     1137      0 localhost.localdom:9000 localhost.localdo:57960 CLOSE_WAIT

改变这一点：

request_terminate_timeout=30s

现在网站工作了。我希望这解决了问题，因为它是断断续续的。
