几周前，我的 VPS 遭受了 DDoS 攻击，IP：81.4.108.50。我刚刚获得了一个 DDoS 过滤 IP：185.34.216.166，并将域名指向它。但我不知道如何将此 IP 绑定到 Apache 服务。我尝试重新启动 Apache 以查看它是否会绑定，结果如下：
apache2：无法可靠地确定服务器的完全限定域名，使用 81.4.108.50 作为 ServerName
Apache 仍然想使用旧 IP。我查看了 apache2.conf，没有找到 IP 地址，也没有任何“监听”的内容。我不知道该怎么做才能让这个过滤后的 IP 绑定到 Apache。我希望这里有人能帮我解决这个问题。谢谢。
服务器版本：Apache/2.2.22（Debian）

答案1
您不要将 IP 绑定到 Apache，而是使用服务器的网络接口进行绑定。
您要尝试做的是让 Apache 监听特定的 IP 地址和端口，因此该部分是正确的。语义。
/etc/apache2/ports.conf 文件中有什么？添加新 IP 后，您是否重新启动过服务器？
您能给我们提供以下命令的输出吗？
ifconfig -a
netstat -tap | grep LISTEN
