http2.4系列相对于http2.2系列新增的功能有
1) MPM支持在运行时装载
2）支持event
3）异步读写
4）在每模块及每目录上指定日志级别
5）每请求配置
6）增强版的表达式分析器
7）毫秒级的keepalive timeout
8）支持主机名的虚拟主机不在需要NameVirtualHost指令
9）支持使用自定义变量
新增的模块由mod_proxy_fcgi,mod_ratelimit,mod_request,mod_remoteip
对应IP的访问做了修改，不在使用order，allow deny这些机制，而是统一使用require进行
一：环境准备：
# yum groupinstall "Development tools" -y
# yum groupinstall "Desktop Platform Development" -y
# yum groupinstall "Server Platform Development" -y
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
yum install gd-devel libjpeg-devel libpng-devel freetype-devel libxml2-devel curl-devel bzip2-devel net-snmp-devel pcre-devel openssl-devel mhash-devel mcrypt libmcrypt-devel libcurl-devel
二：安装arp
[root@master1 ~]# tar xf apr-1.5.2.tar.gz
[root@master1 ~]# cd apr-1.5.2
[root@master1 apr-1.5.2]# ./configure --prefix=/usr/local/apr
[root@master1 apr-1.5.2]# make && make install
三：安装arp-util
[root@master1 ~]# tar xf apr-util-1.5.4.tar.gz
[root@master1 ~]# cd apr-util-1.5.4
[root@master1 apr-util-1.5.4]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
[root@master1 apr-util-1.5.4]# make && make install
四：安装httpd
[root@master1 ~]# tar xf httpd-2.4.18.tar.gz
[root@master1 ~]# cd httpd-2.4.18
[root@master1 httpd-2.4.18]# ./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd --enable-so --enable--ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-modeles=most --enable-mpms-shared=all --with-mpm=event --with-sockets
1:导出httpd头文件
[root@master1 ~]# ln -sv /usr/local/httpd/include /usr/include/httpd
`/usr/include/httpd‘ -> `/usr/local/httpd/include‘
2:环境变量导出：
[root@master1 ~]# echo "export PATH=/usr/local/httpd/bin:$PATH" > /etc/profile.d/httpd.sh
[root@master1 ~]# source /etc/profile.d/httpd.sh
3:建立启动脚本
#!/bin/bash
#
# httpd Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15

# server implementing the current HTTP standards.

四：注意点：
--with-mpm=event 支持event 模型
--enable-so 支持动态装卸模块
--enable-modeles=most 启用大部分模块支持
--enable-mpms-shared=all 所有模块做成共享
--with--xxx 默认目录是/usr. 如果是自己编译，就指定目录。
/usr/local/apache24/build/里config.nice 文件，是查看编译时用到的参数
httpd -M 查看启动的动态模块
五：httpd.conf 配置文件讲解
1：基于IP的控制法则
DocumentRoot "/usr/local/apache24/htdocs"
<Directory "/usr/local/apache24/htdocs">
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
控制特定的IP访问：
Reauire all granted： 允许所有主机访问.
Require all deny ： 拒绝所有主机访问
控制特定的IP访问：
Require ip IPADDR : 指定来源主机访问
Require not ip IPADDR： 拒绝指定来源地址的主机访问。
IPADDR为下面几种形式：
ip: 192.168.1.1
Network/Mask: 192.168.1.1/255.255.255.0
Network/Length: 192.168.1.1/24
Net: 192.168
控制特定主机（HOSTNAME）访问
Require host HOSTNAME
Require not host HOSTNAME
HOSTNAME为下面形式：
FQDN:特定主机
DOMAIN:指定域内所有主机。
2：虚拟主机：
在httpd.conf关闭中心主机：#DocumentRoot
#支持FQDN的不在需要NameVirtualHost指令
在httpd.conf打开Include conf/extra/httpd-vhosts.conf 支持
-------------例子如下--------------------------
<VirtualHost *:80>
DocumentRoot "/vhost/www.test.com"
ServerName www.test.com
ServerAlias test.com
ErrorLog "logs/test_error_log"
CustomLog "logs/test_access_log" combined
<Directory "/vhost/www.test.com">
Options None
AllowOverride None
Require all granted
</Directory>
</VirtualHost>
基于用户验证
<VirtualHost *:80>
DocumentRoot "/vhost/www.test2.com"
ServerName www.test2.com
ServerAlias test2.com
ErrorLog "logs/test2_error_log"
CustomLog "logs/test2_access_log" combined
<Directory "/vhost/www.test2.com">
Options None
AllowOverride AuthConfig //需要认证
AuthType Basic //认证类型为基本认证
AuthName "shouquan" // 这个只是给用户显示一个标题
AuthUserFile /etc/httpd/.userpasswd // 认证的密码文件
Require valid-user //可以读取认证文件的用户，vaild-user 表示所有合法用户
</Directory>
</VirtualHost>
3：生成认证文件 .userpasswd 用户为wskfnso
# htpasswd -c -m /etc/httpd/.userpasswd wskfnso
------------------------------------------------------
4:在window的hosts文件中添加对两个域名的解析.测试如下
