1.?使用網站管理助手環境：http://www.west.cn/faq/list.asp?unid=650?參考此說明啟用設置偽靜態組件

2.??windows2003+iis手工建站環境：http://www.west.cn/faq/list.asp?unid=639?參考此說明加載偽靜態組件? ? ? ? ? ? ? ? ?

3.??然后在配置文件中按以下系統規則配置

Linux下 規則文件.htaccess(手工創建.htaccess文件到站點根目錄)

<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 規則文件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對應屏蔽規則

代碼需添加到對應站點配置文件server段內

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：規則中默認屏蔽部分不明蜘蛛，要屏蔽其他蜘蛛按規則添加即可
