Unattended installation of Linux systems

Project Content : Using Network Installation technology , combined Kickstart Program Scripts , Implementing Unattended Installations Linux Operating System

Purpose of the project : Through this technology , complete unattended installations of hundreds of server systems in batches , save a lot of time.

1 , First, configure it. pxe+dhcp+vsftp the Environment , let's start with a graphical way of generating a Kickstart file.

2 , Install graphical Kickstart Package

[email protected] ~]# Yum install system-config-kickstart-y

3 , Run Graphical System-config-kicstart

[Email protected] ~]# System-config-kickstart

Note : when partitioning , Be sure to understand the hard disk capacity of preinstalled machines , and zoning after zoning planning is done

we're under the experimental environment . , The simplest partition is divided.

Add a network device eth0 Use DHCP type

If you need to install a graphical environment, select , The settings agent is then enabled

Select the required Packages

Client testing:

This is the normal unattended installation interface:

my error is as follows :

my error is file name and saved in /var/ftp the file name is not the same ----- too careless.

Also be aware of file permissions issues
