apache、iis6、ii7独立ip主机屏蔽拦截蜘蛛抓取（适用vps云主机服务器）

最近服务器一直爆红，网站也没有多少流量。发现服务器一些垃圾蜘蛛十分可恨，浪费占用大连服务器资源，根本不顾服务器的性能，有多大劲就使多劲，不停的抓取，而且无视Robots协议。

可以用以下方法实现屏蔽。

Linux下 规则文件.htaccess(手工创建.htaccess文件到站点根目录)

<IfModule mod_rewrite.c>
RewriteEngine On
#Block spider
RewriteCond %{HTTP_USER_AGENT}   "SemrushBot|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|curl|perl|Python|Wget|Xenu|ZmEu"   [NC]
RewriteRule !(^robots\.txt$) - [F]
</IfModule>

windows2003下 规则文件httpd.conf 

#Block spider
RewriteCond %{HTTP_USER_AGENT}   (SemrushBot|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|curl|perl|Python|Wget|Xenu|ZmEu)   [NC]
RewriteRule !(^/robots.txt$) - [F]

windows2008下 web.config

<?xml version="1.0" encoding="UTF-8"?>
  <configuration>
      <system.webServer>
       <rewrite>  
         <rules>         
<rule name="Block spider">
      <match url="(^robots.txt$)"   ignoreCase="false" negate="true" />
      <conditions>
        <add   input="{HTTP_USER_AGENT}"   pattern="SemrushBot|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|curl|perl|Python|Wget|Xenu|ZmEu"   ignoreCase="true" />
      </conditions>
      <action   type="AbortRequest" />
</rule>
        </rules>  
        </rewrite>  
       </system.webServer>
  </configuration>

Nginx对应屏蔽规则：代码需添加到对应站点配置文件server段内

if ($http_user_agent ~ "Bytespider|Java|PhantomJS|SemrushBot|Scrapy|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|perl|Python|Wget|Xenu|ZmEu|^$"   )
{
  return 444;
}

注：“{HTTP_USER_AGENT}”所在行中是不明蜘蛛名称，根据需要添加以"|"为分割。
