RHCE Lab1.1: Auto installation with PXE+DHCP+TFTP+NFS/HTTP/FTP+Kickstart

1. Preparing the boot server (dhcp, tftp)

A. Installing DHCP server

#yum install dhcp

#vi /etc/dhcpd.conf

ddns-update-style interim;
ignore client-updates;

allow booting;
allow bootp;

class "pxeclients"{
match if substring(option vendor-class-identifier,0,9) = "PXEClient";
filename "centos5u2/pxelinux.0";
next-server 192.168.75.11;
}
subnet 192.168.75.0 netmask 255.255.255.0 {
option routers 192.168.75.2;
option subnet-mask 255.255.255.0;
option domain-name "";
option domain-name-servers 192.168.75.2;
option time-offset -18000;
range dynamic-bootp 192.168.75.1 192.168.75.254;
default-lease-time 21600;
max-lease-time 43200;
}

#service dhcpd restart

B. Installing TFTP server

#yum install xinetd

#yum install tftp-server

#vi /etc/xinetd.d/tftp

service tftp
{
    socket_type     = dgram
    protocol        = udp
    wait            = yes
    user            = root
    server          = /usr/sbin/in.tftpd
    server_args     = -s /tftpboot
    disable         = no
}

#mkdir /mnt/iso

#mount -o loop centos.5.2.iso  /mnt/iso

2. Preparing the installation server (HTTP, NFS, FTP)
Please refer to RHCT Lab1

3. Preparing the ks.cfg file

Please refer to RHCE Lab1

4. Installing the CentOS5 client with PXE

Set BIOS to boot from Network PXE

boot:autoinstall
