在线等：Centos:apache+tomcat+nginx+php+jsp,出502/504错误

[苦瓜不甜]

Centos系统，架构为apache+tomcat+nginx+php+jsp+mysql，
后台PHP及mysql访问正常，前台Jsp访问一直出错，原来一直出出502 bad gateway错误，根据网上建议修改Vhost相应的配置文件增加如下内容：
client_max_body_size 200M;

large_client_header_buffers 4 16k;
client_body_buffer_size 128k;
proxy_connect_timeout 600;
proxy_read_timeout 600;
proxy_send_timeout 600;
proxy_buffer_size 64k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
现却出504 gateway time-out，哪位碰到过类似情况，是什么问题？怎么解决的？Thanks。

我自己来结贴吧。 找到问题原因，主要是因为硬盘本身问题，造成站点内WEB-INF文件夹无法访问，无法访问其下的Lib和Classs文件，重新上传该文件夹搞定。
