我尝试http://domain.com/test.html
从互联网访问,但出现错误
服务器运行的是 CentOS
我正在使用 DSN 托管(yandex.ru)domain.com
通过 IP ping 服务器 = OK
通过域名 Ping 服务器 = OK === nslookup = OK
wget http://domain.com/test.html
本地 = OK(apache 配置正确)
服务器有以下内容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

请建议我还应该检查什么?
答案1
您的防火墙似乎阻止了端口 80。尝试使用以下方法打开它
iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT
如果有效则保存当前配置
service iptables save
这将更新/etc/sysconfig/iptables
文件,以便下次服务启动时端口 80 将保持打开。
