编译安装HTTPD 2.4.9版本
服务脚本：/etc/rc.d/init.d/httpd
脚本配置文件路径：/etc/sysconfig/httpd
运行目录：/etc/httpd
配置文件：
主配置：/etc/httpd/conf/httpd.conf
扩展配置：/etc/httpd/conf.d/*.conf
监听的Socket: tcp的80, 443是https/tcp的监听端口
在内核中使用小于1023的端口的只有管理员
文档根目录：/var/www/html
CGI目录：/var/www/cgi-bin/
依赖于更高版本的apr和apr-util。apr全称为apache portable runtime(apache运行时移植工具)、是让apache跨平台的工具、是个底层库。
这里的安装不做过多的详细解释了、可以参考之前写过的文章、安装都是大同小异：

后续的配置：
1) 修改服务脚本 先把 # cp /etc/rc.d/init.d/httpd /etc/rc.d/init.d/httpd 24
修改下apache自己的服务脚本 vim /etc/rc.d/init.d/httpd 24 // 修改的部分我会要红色注释
#!/bin/bash

esac
exit $RETVAL
2) 输出二进制程序
# vim /etc/profile.d/httpd24.sh
export PATH=/usr/local/apache/bin:$PATH
3) 修改 apache下的 vim /etc/httpd24/httpd.conf
开启 ServerName 172.16.21.1:80 // 172.16.21.1 这是我的本机ip地址
安装配置好之后我们查看一下刚安装好的HTTPD版本：
# httpd -v
最后可以启动了、再查看一下端口是否在监听状态了、当然你还可以给他提供一个服务脚本：
# apachectl star
# ss -tnl
