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 "
test.org
";
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#mkdir -p /tftpboot/centos5u2
#mkdir -p /tftpboot/centos5u2/pxelinux.cfg
#cp /usr/lib/syslinux/pxelinux.0 /tftpboot/centos5u2/
