Kickstart
With kickstart, a system administrator can create a file that contains answers to all frequently asked questions during installation to automatically install Red Hat Enterprise Linux Kickstart similar to Jumpstart or Mic in Oracle Solaris Rosoft Unattended installation of Windows
It is difficult to write kickstart scripts manually, and we use our system to make them with our own package tools. But there will be bugs, and the selection package needs to be added manually. Environment Deployment

Download Kickstart and httpd services from the real machine root
with your own Yum source, can refer to blog:http://blog.csdn.net/dream_ya/article/details/79130384

Yum Install System-config-kickstart httpd-y      # # #用yum安装

use RPM to see if the software was installed successfully, as shown below

Systemctl start httpd                                      # # #开启服务
 chkconfig httpd on                                        # # #开机自动开启服务
 systemctl stop Firewalld                                   ### Close firewall
 systemctl mask firewalld                                   # # #冻结防火墙

Kickstart make Ks.cfg script the real machine root

System-config-kickstart                                     # # #启动kickstart
