nigx屏蔽无用爬虫

大量恶意爬虫占用系统资源，频繁访问服务器快耗竭。快速屏蔽掉无用爬虫可以参考下面方法。

3.229.95.193 - - [28/Apr/2025:08:27:58 +0800] ＂GET /news/1563.html HTTP/1.1＂ 200 11642 ＂-＂ ＂Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Amazonbot/0.1; +https://developer.amazon.com/support/amazonbot) Chrome/119.0.6045.214 Safari/537.36＂

 通过宝塔面板，伪静态重写，代码如下：

 

if ($http_user_agent ~* "SemrushBot/7~bl|YandexBot|Amazonbot/0.1|GPTBot/1.2|GPTBot|Bytespider|meta-externalagent|Amazonbot|GPTBot|Meta-ExternalAgent|FeedDemon|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms|^$" ) {

     return 403;

}

重写之后，系统负载正常。
