如何封杀IP?

1.新建个配置文件：deny_block_ip.conf

#拒绝单个ip
#deny 192.168.1.15;

#允许某个ip
# allow 192.168.1.15;

#拒绝所有
# deny all;

#允许所有
# allow all;

#拒绝某个区间
#deny 192.168.1.0/25; 

 根据需求，写入相应的ip策略.

2.deny_block_ip.conf 加入到nginx.conf

include deny_block_ip.conf;

 3.重启nginx

/usr/local/nginx/sbin/nginx -s reload

nginx如何对请求的次数进行控制？

相关操作：

检查修改的配置是否正确：/usr/local/nginx/sbin/nginx -t

下面表示配置正确：

the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
　　the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully

重新加载配置：

kill -HUP `cat /usr/local/nginx/nginx.pid`

或者重新启动：

/usr/local/nginx/sbin/nginx -s reload

为 Cacti 添加 Nginx status 监控。
