添加一段代码防范来自搜索引擎的CC攻击

搜索引擎有成千上万，网站做到一定时间少不了被一些同行或心理不健康的人拿来恶意攻击，比较常见的有Ddos,CC等系列攻击，有些垃圾引擎甚至会被变态利用作为CC攻击的工具，解决上面的办法除了购买高安全云防护产品之外，还有一个主要就是针对个人站长及中小企业没有专业的防护前提下可以考虑的，但是这个方法不是一本万利的，没有哪一个代码可以做到横扫千军甚至永享太平的，废话咱就不多说了， 下面的方法将教大家如何防范，直接上码：

Nginx服务器防止CC攻击代码，以宝塔为例

以宝塔面板为例，打开 网站 – 你的网站 – 设置 – 配置文件，在 #禁止访问的文件或目录 内容的下方加入以下代码，第40行

代码如下：

最终添加后的成功效果：

[rihide]#禁止访问的文件或目录
    location ~ ^/(\.user.ini|\.htaccess|\.git|\.svn|\.project|LICENSE|README.md)
    {
        return 404;
