Kickstart installation Configuration

     KickstartAutomated Installation Platform

As the company's business continues to grow, it often needs to purchase new servers, and requires Linux to be installed in a consistent way, to facilitate future maintenance and management, and to waste more time on each manual installation of the Linux system, but wouldn't it be better if we had a way to save time?

Large and medium-sized Internet companies on a procurement server hundred, if the use of manual one installation, a person must make a bad n CD, how many overtime to complete this "arduous" task, we can see the whole artificial to complete such work is too waste of manpower, there is no automated installation platform, Through an existing system and then cloning or copying to the new server. The kickstart can do the work without any difficulty.

PXE (Preboot Execute environment, pre-boot execution Environment) is the latest technology developed by Intel Corporation, working in the network mode of client/server, enabling workstations to download images from remote servers over the network, This supports booting the operating system over the network, during the boot process, the terminal requires the server to assign an IP address, and then uses the TFTP (trivial File Transfer Protocol) protocol to download a boot package to native memory execution.

To use the Kickstart installation platform, the complete architecture includes the following: Kickstart+dhcp+nfs+tftp+pxe, from the architecture you can see roughly the services that need to be installed, such as DHCP, TFTP, NFS, Kickstart/pxe, and so on.

2. [Email protected]_168_77_199 ~]# cat/etc/issue
   CentOS Release 6.6 (Final)
   Kernel \ r on an \m

4. [Email protected]_168_77_199 ~]# uname-r
   2.6.32-504.el6.x86_64

6. Yum install-y dhcp* tftp* nfs* syslinux-y

8. First configure the TFTP service: vi/etc/xinetd.d/tftp, just change disable = yes to disable = No.

10. Ln-s/var/lib/tftpboot//link to the root directory below

12. cd/tftpboot/; cp/usr/share/syslinux/pxelinux.0. ;  CP/MNT/IMAGES/PXEBOOT/{VMLINUZ,INITRD.IMG}. ; mkdir pxelinux.cfg; Cp/mnt/isolinux/isolinux.cfg./default

14. Add in default: Label centos6.6
    Kernel Vmlinuz
    Append ks=nfs:192.168.77.199:/data/centos/ks.cfg ksdevice=eth0 initrd=initrd.img

16. Mkdir-p/data/centos; cd/data/centos/Shared CentOS Directory vi/etc/exports add:/data/centos * (Rw,sync); Nohup cp/mnt/*. -A & Background copy the disc file to a shared directory under CentOS

18. config ks.cfg   cd/data/centos    VI/ETC/KS.CFG Add the following configuration content: Ks.cfg can also be modified by copying the anaconda-ks.cfg under the root directory

21. To configure the DHCPD service:

23. Ddns-update-style interim;ignore client-updates;next-server 192.168.77.199;filename "pxelinux.0"; allow booting; Allow Bootp;subnet 192.168.77.0 netmask 255.255.255.0 {#---default gatewayoption routers 192.168.77.1;option su Bnet-mask 255.255.255.0;range DYNAMIC-BOOTP 192.168.77.100 192.168.77.200;host ns {hardware Ethernet 00:1a:a0:2b:38: 81;fixed-address 192.168.77.101;}}

25. Service xinetd Restart

27. Service NFS Restart

29. Service DHCPD Restart can be installed automatically after restarting it but requires manual input centos6.6

30. Automatic installation no need to enter anything: Ks.cfg file configuration do not change just change the default configuration as follows:

    
    

    Default Vesamenu.c32
    #prompt 1
    Default KS
    Timeout 600
