linux iptables导致httpd网页打不开

  问题：httpd 服务已启动，80端口已开，但是网页就是打不开，重启服务器还是不行

忽然想看看log，记录如下：

   [Fri Jul 15 00:41:03 2011] [notice] SELinux policy enabled; httpd running as context root:system_r:httpd_t:s0

   [Fri Jul 15 00:41:03 2011] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)

   [Fri Jul 15 00:41:03 2011] [notice] Digest: generating secret for digest authentication ...

   [Fri Jul 15 00:41:03 2011] [notice] Digest: done

   [Fri Jul 15 00:41:03 2011] [notice] Apache/2.2.3 (CentOS) configured -- resuming normal operations

  看到 suexec，明白了，果断iptables -L ,结果如下：

   ACCEPT     all  --  anywhere             anywhere            

ACCEPT     icmp --  anywhere             anywhere            icmp any 

ACCEPT     esp  --  anywhere             anywhere            

ACCEPT     ah   --  anywhere             anywhere            

ACCEPT     udp  --  anywhere             224.0.0.251         udp dpt:mdns 

ACCEPT     udp  --  anywhere             anywhere            udp dpt:ipp 

ACCEPT     tcp  --  anywhere             anywhere            tcp dpt:ipp 

ACCEPT     all  --  anywhere             anywhere            state RELATED,ESTABLISHED 

ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:ssh 

REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited 

 

     全部干掉，iptables -F ，再打开网页，显示正常
