一、Centos7系统下实现httpd-2.2的安装，并分别实现prefork、worker、event等几种工作方式
二、简述request报文请求方法和状态响应码
三、详细描述httpd虚拟主机、站点访问控制、基于用户的访问控制、持久链接等应用配置实例
这里只演示Centos7基于ip的虚拟主机：
[root@bogon conf]# ip addr add 192.168.1.4/16 dev ens33
[root@bogon conf]# ip a l
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

站点访问控制：
vim /etc/httpd/conf/httpd.conf, 注释下面内容。
基于用户的访问控制：
