脚本如下:

#!/bin/sh
nginx_home = /Data/app_1/nginx
log_path = /Data/logs
/usr/bin/tail -n50000 $log_path/access.log \
|awk ‘$8 ~/aspx/{print $2,$13}’ \
|grep -i -v -E “google|yahoo|baidu|msnbot|FeedSky|sogou” \
|awk ‘{print $1}’|sort|uniq -c |sort -rn \
|awk ‘{if($1>150)print “deny “$2″;”}’> $nginx_home/conf/vhosts/blockip.conf
/bin/kill -HUP `cat $nginx_home/nginx.pid`

也可以通过分析nginx日志过滤出频繁访问IP，直接用iptables屏蔽这个IP，就用不着重启nginx了，并且屏蔽效果更好。

单个IP的命令是
iptables -I INPUT -s 124.115.0.199 -j DROP

封IP段的命令是
iptables -I INPUT -s 124.115.0.0/16 -j DROP

封整个段的命令是
iptables -I INPUT -s 194.42.0.0/8 -j DROP

封几个段的命令是
iptables -I INPUT -s 61.37.80.0/24 -j DROP
iptables -I INPUT -s 61.37.81.0/24 -j DROP

刚才不小心搞的自己都连不上了-_-!!!
iptables -I INPUT -p tcp –dport 80 -s 124.115.0.0/24 -j DROP
以后用这种只封80端口就行了，不会出问题!

iptables -I INPUT -p tcp –dport 80 -s 124.115.0.0/24 -j DROP

iptables -I INPUT -s 61.37.81.0/24 -j DROP

解封
iptables -F
清空
iptables -D INPUT 数字
