一、防止DDOS、CC攻击
http { limit_conn_zone $binary_remote_addr zone=perip:10m; limit_conn_zone $server_name zone=perserver:10m server { limit_conn perip 10; #单个客户端ip与服务器的连接数. limit_conn perserver 100; #限制与服务器的总连接数 }
二、禁止爬虫
server { listen 80; server_name 127.0.0.1; #添加如下内容即可防止爬虫 if($http_user_agent~*"qihoobot|Baiduspider|Googlebot|Googlebot-Mobile|Googlebot-Image|Mediapartners-Google|Adsbot-Google|Feedfetcher-Google|Yahoo!
