云主机云服务器

客户如果使用的美国VPS是正常的搜索引擎蜘蛛访问，不建议对蜘蛛进行禁止，否则网站在百度等搜索引擎中的收录和排名将会丢失，造成客户流失等损失。

然后在配置文件中按以下系统规则配置

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：规则中默认屏蔽部分不明蜘蛛，要屏蔽其他蜘蛛按规则添加即可
