请问伙伴们，自己的 csf 防火墙是不是出现了什么配置错误？

目前已经关闭了 selinux 和 firewalld，自己的 csf 配置如下： https://segmentfault.com/q/1010000015367181 （文字超出限制，发到上面这个链接了）

网站是正常显示的状态，配置是：centos7+openresty +csf firewall+php7+mysql
csf 防火墙里面的配置文件，固定 ip 访问次数我设置的很高啊，waf 里面设置的 120/60，

感觉是 nginx 配置有问题，可以贴下 nginx 配置文件

感觉是 WAF 的问题，我的是连续刷新十次就不能访问了

1.防火墙问题？
2.内存不够，连接的用户过多？
3.web 服务的配置文件设置不合理？
