    早上一个朋友告知其没有流量的博客突然出现访问很慢，然后打不开提示信息主机资源超量等信息（具体的提示我也忘记复制下来），大概意思就是占用资源过大短期被屏蔽。因为是虚拟主机，采用的是APACHE架构服务，所以比较简单，直接帮他登录CPANEL面板取得日志文件，然后查看后吓一跳。

    原来是来自YisouSpider蜘蛛的爬行导致占用内存和CPU过大导致的资源消耗，一个小小的博客没有流量的怎么可能会这样呢，我看他的博客只有几篇文章而已。
    解决方法很简单，我们直接在.htaccess文件中屏蔽这个IP就可以。
    1. Order Allow,Deny
    2. Allow from all
    3. Deny from 42.120.161.43
    复制代码
    在.htaccess文件中增加上面三行，如果有多个IP地址的话，用空格隔开。搜索了一下，发现出现这样问题的还真不少，而且还看到有人专门整理了所有的YisouSpider蜘蛛IP地址，我们可以全部屏蔽未雨绸缪，也可以等有问题的时候一个个添加。
    网友整理的所有YiSouSpider IP地址：

    PS：如果我们是NGINX环境系统，我们也可以到自己当前网站的.CONF文件中添加
    1. deny 42.120.161.43;
    复制代码
    这样我们一样可以屏蔽当前这个IP地址的访问。
    PS：这里在补充Nginx环境屏蔽YisouSpider爬虫的方法，我们可以直接将整个爬虫User Agent端口屏蔽，反正也没有多大的用途。
    1. if ($http_user_agent ~* "YisouSpider") {
    2. return 403;
    3. }
    复制代码
    在我们当前站点的.conf文件中添加上面的脚本，保存替换之后重启Nginx生效，这样我们就可以让所有的YisouSpider返回403。
