在Centos+nginx+wordpress环境下启动iptables 网站返回502
网站环境:Centos nginx php(wordpress)

现在的问题总结如下:
启动iptables网站返回502,关闭iptables网站打开正常

iptables 设置如下:
Chain INPUT (policy DROP 1 packets, 139 bytes)
 pkts bytes target     prot opt in     out     source               destination         
    0     0 ACCEPT     all  --  lo     any     anywhere             anywhere            
   17  1460 ACCEPT     all  --  any    any     anywhere             anywhere            state RELATED,ESTABLISHED 
    1    40 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:ssh 
    0     0 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:mysql 
    2    80 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:http 
    0     0 ACCEPT     all  --  lo     any     anywhere             anywhere            
    0     0 ACCEPT     icmp --  any    any     anywhere             anywhere            
    0     0 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:pptp 
    0     0 ACCEPT     gre  --  any    any     anywhere             anywhere            

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 16 packets, 4024 bytes)
 pkts bytes target     prot opt in     out     source               destination         
    2    80 ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp spt:http 

开启了lo,开启了80,开始了9000

在开启iptables时,静态的网页时能打开的,但是切换回wordpress是又返回502.

查看error-log都是:
2013/09/26 01:45:37 [error] 1745#0: *106 recv() failed (104: Connection reset by peer) while reading response header from upstream, client:, server: xiaobuxun.me, request: "POST /wp-admin/admin-ajax.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xiaobuxun.me", referrer: "http://xiaobuxun.me/wp-admin/post-new.php"

我考虑是iptables的问题,是fastCGI用的9000端口没有打开,,但是我已经配置上了,为什么还是返回502,求大神指教了!!!

iptables nginx fastCGI
