我有一台服务器，我可以使用实时 IP 进行 ssh。该服务器通过 DMZ 端口连接。每当我尝试访问服务器中的 Web 服务器时，都会收到“连接已重置”的消息。
我的 SeLinux 已关闭。我尝试关闭 IPTABLES。我更改了 httpd 以监听分配给 etho 的 LAN IP
Listen 192.168.0.254:80
什么都没起作用。
这是 IPTABLES -L 给我的结果

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
答案1
（98）地址已在使用中：make_sock：无法绑定到地址 0.0.0.0:80 没有可用的监听套接字，正在关闭
这意味着其他程序已经在监听端口 80，您的服务器无法绑定到该端口。该端口已被占用。您可能有多个使用端口 80 的“Listen”语句，或者另一个应用程序已占用该端口。
以 root 身份输入：
netstat -aeenp | egrep "User|:80"
这应该告诉您在该端口上监听什么。
