Kickstart automated Installation

Kickstart Automated Installation

First you need to install the software:

Yum install–y dhcp* tftp* nfs-utils

Yum install–y syslinux (no pxelinux.0 required to install syslinux)

1 , configure the TFTP server:

vi/etc/xinetd.d/tftp change Disable = yes to No.

2 , TFTP+PXE configuration

To implement a remote installation system, you need to specify the relevant PXE kernel module and related parameters in the Tftpboot directory. The configuration steps are as follows:

mount/dev/cdrom/mnt/# Mounting Discs

ln–s/var/lib/tftpboot//# make a soft connection

Cd/tftpboot # Enter the/tftpboot directory

cp/usr/share/syslinux/pxelinux.0. # Copy the pxelinux.0

/tftpboot Catalogue

cp/mnt/images/pxeboot/{vmlinux,initrd.img}. # Copy the kernel to the TFTP directory

mkdir-p pxelinux.cfg # Create the Pxelinux.cfg directory under the/tftpboot directory

Cp/mnt/isolinux/isolinux.cfg/tftpboot/pxelinux.cfg/default

Vi/tftpboot/pxelinux.cfg/default change the content to read as follows:

Default centos6.5

Timeout 600

Display Boot.msg

Menu Background Splash.jpg

Menu title Welcome to CentOS 6.5!

Menu Color Border 0 #ffffffff #00000000

Menu Color SEL 7 #ffffffff #ff000000

Menu Color Title 0 #ffffffff #00000000

Menu Color tabmsg 0 #ffffffff #00000000

Menu Color Unsel 0 #ffffffff #00000000

Menu Color Hotsel 0 #ff000000 #ffffffff

Menu Color Hotkey 7 #ffffffff #ff000000

Menu Color ScrollBar 0 #ffffffff #00000000

Label centos6.5

Kernel Vmlinuz

Appendks=nfs:192.168.10.142:/data/centos/ks.cfg Ksdevice=eth0 initrd=initrd.img

Label Local

Give default 777 permission chmod 777 default

Configuration Note: 192.168.223.132 is a kickstart server,/data/centos is the Directory of NFS shared Linux images and the path to the Linux installation files. Ks.cfg is the Kickstart Master profile, the answer file, Ksdevice=eth0 indicates that there are multiple NICs when the client installs from eth0

3 , configure the DHCP server

Dhcp The configuration file of the server is/etc/dhcp/dhcpd.conf, and his configuration file is changed to:

Ddns-update-style Interim;

Ignore client-updates;

Next-server 192.168.223.132;

FileName "pxelinux.0";

Allow booting;

Allow BOOTP;

Subnet 192.168.223.0 netmask 255.255.255.0 {

Option routers 192.168.223.1;

Option Subnet-mask 255.255.0.0;

Range DYNAMIC-BOOTP 192.168.223.50 192.168.223.100;

Host NS {

Hardware Ethernet 00:1a:a0:2b:38:81;

Fixed-address 192.168.223.88;}

}

Configuration Description:

Subnet for the network address, netmask is the mask, which indicates which network is assigned the IP address and must be in the same network as the host.

Option Routers after the IP is assigned, the client's gateway address, Optionsubnet-mask, is the mask for the client.

Range DYNAMIC-BOOTP is the assigned IP address range.

Next-server as the address of the TFTP server, filename is the file required for PXE installation

Host NS for a MAC address, configure a fixed IP address, bind

Once configured, restart/ETC/INIT.D/DHCPD restart

4 , Nfs+kickstart configuration

Mkdir-p/data/centos

cp-a/mnt/*/data/centos/# copy all the files in the CD to the/data/centos directory

Vi/etc/exports Add a line/data/centos * (Rw,sync)

means to share the/data/centos to everyone, read and write.

CP Anaconda-ks.cfg/data/centos/ks.cfg

Configure the Kickstart file, vi/data/centos/ks.cfg change to the following:

Reboot

Give Ks.cfg 777 permission chmod 777 Ks.cfg

5 , restart all services

/ETC/INIT.D/DHCPD restart

/etc/init.d/xinetd restart

/etc/init.d/rpcbind restart

/etc/init.d/nfs restart
