Tutorials for installing CentOS using Kickstart automation

Objective

Because of the need to centrally deploy CentOS in a tidal x86 server to build a large data platform based on Hadoop, usually contact SLEs (SuSE Linux Enterprise server) More and implemented automated installation of CD-ROM or PXE network based on Autoyast (subsequent sharing of specific implementation methods). This is mainly through learning kisckstart to achieve the simplest way to automate the installation of optical disk CentOS, while most of the online tutorials are not fully applicable to their own environment, this article will no longer repeat the kickstart related concepts, details can be referred to the extended reading.

Kickstart is one of the most common methods of Linux automation installation

Environmental preparedness

Custom Systems

Centos-6.4-x86_64

Official Download Address-http://wiki.centos.org/Download

Installing packages

Agent Internet tips, export http_proxy=ip:port

The code is as follows:

Production process

Directory structure

Copy CentOS original mirror content, do not do any streamlining

The code is as follows:

Mkdir/mnt/centos

Mount/dev/sr0/mnt/centos

Mkdir/tmp/iso

Cp-r/mnt/centos/*/tmp/iso

Add Kickstart configuration file

File path and installation method can be defined freely

Copy Code

The code is as follows:

Cd/tmp/iso/isolinux

#修改引导, pay attention to the ks= part.

VI isolinux.cfg

Label Linux

Menu label ^install or upgrade an existing system

Menu default

Kernel Vmlinuz

Append initrd=initrd.img ks=cdrom:/isolinux/ks.cfg

#手动增加Kickstart配置文件

VI ks.cfg
