目前除了我們常見的搜索引擎如百度、Google、Sogou、360等搜索引擎之外，還存在其他非常多的搜索引擎，通常這些搜索引擎不僅不會帶來流量，因為大量的抓取請求，還會造成主機的CPU和帶寬資源浪費，屏蔽方法也很簡單，按照下面步驟操作即可，原理就是分析指定UA然后屏蔽。
首先進入寶塔面板，文件管理進入 /www/server/nginx/conf 目錄，新建空白文件 kill_bot.conf。然后將以下代碼保存到當前文件中。

保存后返回到寶塔 - 【網(wǎng)站】-【設(shè)置】點擊左側(cè) 【配置文件】選項卡，在 #SSL-START SSL相關(guān)配置，請勿刪除或修改下一行帶注釋的404規(guī)則 上方空白行插入代碼： include kill_bot.conf; 保存后即可生效，這樣這些蜘蛛或工具掃描網(wǎng)站的時候就會提示403禁止訪問。
