Use Kickstart to install CentOS automatically

Use Kickstart to install CentOS automatically

Preface

Because we need to centrally deploy CentOS in inspur x86 servers to build a Hadoop-based big data platform, and usually access SLES (SuSE Linux Enterprise Server) there are many and automatic installation Based on the Autoyast method using the CD or PXE network has been realized (the specific implementation method will be shared later ). This time, we will learn how to use Kisckstart to automate the installation of CentOS in the simplest CD mode. Most online tutorials are not fully applicable to our own environments. This article will not repeat the concepts of Kickstart, for details, refer to extended reading.

Kickstart is one of the most common Linux automated installation methods.

Install software package

Tips for proxy surfing, export http_proxy = ip: port

yum -y install createrepo mkisofs

Create process directory structure

Copy the original CentOS image without any streamlining

mkdir /mnt/centosmount /dev/sr0 /mnt/centosmkdir /tmp/isocp -r /mnt/centos/* /tmp/iso

Add Kickstart configuration file

The file path and installation method can be freely defined.

Generate dependency and ISO files

Note the accuracy of paths and commands

cd /tmp/isocreaterepo -g repodata/*comps.xml . mkisofs -o /tmp/CentOS-6.4_64_auto.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table  -joliet-long  -R -J -v -T /tmp/iso/

Test and Suggestions

Two references are recommended. We recommend that you perform repeated tests and verification on the Virtual Machine before deploying it on the physical machine.
