我试图从互联网上访问http://domain.com/test.html ，但得到错误
服务器正在运行CentOS
我正在使用DSN托pipe（yandex.ru）为domain.com
Ping服务器通过ip = OK
Ping域服务器=确定=== nslookup =确定
wget http://domain.com/test.html本地= OK（apacheconfiguration成功）
服务器有以下iptables ：
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,ESTAB LISHED ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:s sh REJECT all -- anywhere anywhere reject-with icmp-ho st-prohibited
UPD： iptables -nL

请推荐我还要检查什么？
它看起来像你的防火墙阻止端口80.尝试打开它
iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT
如果这个工作，然后保存当前的configuration
service iptables save
它将更新/etc/sysconfig/iptables文件，以便下次启动服务时，端口80将保持打开状态。
