服务端：
1、DHCP服务 指定分配ip地址 定位引导文件next-server //指向TFTP路径
filename //引导程序文件位置
—————————————————————————2、TFTP服务（简单文件传输协议） UDP69端口
高效率 容量小（引导程序pxelinnx.0（syslinux包），压缩内核vmlinuz，
系统初始化文件initrd.img，启动菜单default）—————————————————————————
3.FTP （vsftp） 文件传输协议 系统镜像（centos7）
安全 容量大 TCP 20（数据传输）， 21（连接）—————————————————————————
安装包：dhcp， tftp-server， vsftp， syslinux
4.安装并配置kickstart无人值守
