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
