阿帕奇 – WordPress的Pingback DDoS攻击我的服务器

我在CentOS上有一个Apache服务器，这些是我从access_log获得的第一行：

而MB在MB的线路上继续下去。 我已经尝试了这种方法，但是它不工作：

Blocking WordPress Pingback Verification DDoS

• Apache如何加载重复的configuration选项？
• Apache停止响应几秒钟
• 如何将Apache VirtualHost映射到OpenVPNnetworking上的IP地址？
• 然后Nginx前面apache
• 通过ubuntu 16发布Apache SVN的Access文件

我也尝试将服务器移到CloudFlare，但是他们也没有阻止这种大规模的攻击。 有人可以帮帮我吗？

重要说明：我的网站与WordPress没有任何关系。
