Centos kickstart Unattended Installation System

PXE: A boot mode. During the startup process, the terminal requires the server to allocate an IP address and then download a startup package to the local memory for execution using the TFTP protocol, the startup package completes the basic software settings of the terminal to guide the terminal operating system that is pre-installed on the server.

Kickstart: an unattended installation method. It works by recording typical parameters that require manual intervention during installation and generating a file named KS. cfg.

1. Install the required software package

Yum-y install httpd

Yum-y install syslinux

Yum-y install TFTP-Server

Yum-y install DHCP

Yum-y install system-config-kickstart

2. Configure DHCPD. conf

Vim/etc/hdcpd. conf

Ddns-Update-style interim;

Ignore client-updates;

Next-server 192.168.222.129; # IP address of the TFTP Server

Filename "pxelinux.0 ";

Subnet 192.168.222.0 netmask 255.255.255.0 {

Option routers 192.168.222.129;

Option subnet-mask limit 255.0;

Range dynamic-BOOTP 192.168.222.100 192.168.222.150;

Default-lease-time 21600;

Max-lease-time 43200;

}

3. Configure TFTP

Vim/etc/xinetd. d/TFTP

Service tftp

{

Socket_type = dgram

Protocol = UDP

Wait = Yes

User = root

Server =/usr/sbin/in. tftpd

Server_args =-S/var/lib/tftpboot

Disable = No

Per_source = 11

CPIs = 100 2

Flags = IPv4

}

4. Required Documents

Initrd. IMG: Image File

Vmlinuz: Kernel File

Pxelinux.0: PXE network boot file

Isolinux. cfg: information during automatic installation, which must be changed to default

1. Copy Related Files
