首先在模块⇒AMRewrite中，创建新的.conf，例如取名zencart_301_useragent.conf

将以下规则存放入zencart_301_useragent.conf，保存

#这里屏蔽了以下十五种蜘蛛
if ( $http_user_agent ~ AhrefsBot ){
return 403;
}
if ( $http_user_agent ~ YandexBot ){
return 403;
}
if ( $http_user_agent ~ MJ12bot ){
return 403;
}
if ( $http_user_agent ~ RU_Bot ){
return 403;
}
if ( $http_user_agent ~ Ezooms ){
return 403;
}
if ( $http_user_agent ~ Yeti ){
return 403;
}
if ( $http_user_agent ~ BLEXBot ){
return 403;
}
if ( $http_user_agent ~ Exabot ){
return 403;
}
if ( $http_user_agent ~ YisouSpider ){
return 403;
}
if ( $http_user_agent ~ sandcrawlerbot ){
return 403;
}
if ( $http_user_agent ~ ShopWiki ){
return 403;
}
if ( $http_user_agent ~ Genieo ){
return 403;
}
if ( $http_user_agent ~ Aboundex ){
return 403;
}
if ( $http_user_agent ~ coccoc ){
return 403;
}

对应虚拟主机站点，编辑，rewrite规则中选择 zencart_301_useragent.conf，保存即可。
如果你不需要301重定向，或不需要屏蔽上方的蜘蛛，将不需要的部分删除即可。
