KeepAlive
KeepAlive' Timeout
作用
使用Require配置项实现访问控制，按先后顺序限制
可用于<Location>、<Directory>、<Files>、 <Limit>配置段中
Require配置项的常见语法Require all granted
Require all denied
Require local
Require [not] host <主机名或域名列表>
//使用not禁止访问时要将其置于<RequireAll> </RequireAll>容器中并在容器中指定相应的限制策略
Require [not] ip <IP地址或网段列表>在Linux系统中安装DNS、HTTP服务，并设置DNS服务。
