# 1.kickstart script

Overview of Kickstart

Using kickstart, system administrators can create a file that contains answers to all common questions during installation to automatically install Red Hat Enterprise Linux

Kickstart is similar to unattended installation of Jumpstart or Microsoft Windows in Oracle solaris

The kickstart script is a script file that automatically answers all problems with the system during installation.

This file can be installed automatically.

After the system is installed, it will be generated in the root home directory of the system

The file anaconda-ks.cfg is the kickstart script generated with this system as a template.

# production of 2.kickstart script #

It is very difficult to write kickstart manually

The system-config-kickstart tool in the system can make kickstart graphically.

Production process:

System-config-kickstart## opens the drawing ks making tool

Start production:
