1）安装DHCP软件包
yum install dhcpd -y
配置dhcpd.conf
ddns-update-style none;
ignore client-updates;
allow booting;
allow bootp;
subnet 192.168.18.0 netmask 255.255.255.0 {
range 192.168.18.20 192.168.18.40;
option subnet-mask 255.255.255.0;
default-lease-time 21600;
max-lease-time 43200;
next-server 192.168.18.8;
filename "pxelinux.0";
}
2）安装配置TFTP服务器
yum install tftp-server -y
配置/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
cps= 100 2
flags= IPv4
}
3）拷贝启动引导文件到FTP
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
mount /dev/cdrom /mnt
cp /mnt/isolinux/{vmlinuz,initrd.img} /var/lib/tftpboot/
mkdir -p /var/lib/tftpboot/pxelinux.cfg
cp /mnt/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
配置default
default linux
#prompt 1
timeout 600
display boot.msg
menu background splash.jpg
menu title Welcome to CentOS 6.6!
menu color border 0 #ffffffff #00000000
menu color sel 7 #ffffffff #ff000000
menu color title 0 #ffffffff #00000000

menu color hotsel 0 #ff000000 #ffffffff
menu color hotkey 7 #ffffffff #ff000000
menu color scrollbar 0 #ffffffff #00000000
label linux
menu label ^Install or upgrade an existing system
menu default
kernel vmlinuz
append initrd=initrd.img ks=http://192.168.18.8/ks.cfg
label vesa
menu label Install system with ^basic video driver
kernel vmlinuz
append initrd=initrd.img xdriver=vesa nomodeset
label rescue
menu label ^Rescue installed system
kernel vmlinuz
append initrd=initrd.img rescue
label local
menu label Boot from ^local drive
localboot 0xffff
label memtest86
menu label ^Memory test
kernel memtest
append -
4）安装配置http
yum install httpd -y
[root@kickstart conf]# grep ServerName httpd.conf |grep -v "#"
ServerName 192.168.18.8
5）拷贝安装介质
mount /dev/cdrom /mnt
cp -fr /mnt/* /var/www/html/
6）制作ks.cfg
yum install system-config-kickstart -y
system-config-kickstart 图形配置保存ks.cfg到/var/www/html/
ks.cfg配置文件（最小化安装系统）
#platform=x86, AMD64, or Intel EM64T

# Firewall configuration
firewall --disabled

part swap --fstype="swap" --size=2000
part / --fstype="ext4" --grow --size=1
%packages --nobase
ks.cfg保存到/var/www/html/
7）启动服务
/etc/init.d/dhcpd start
/etc/init.d/xinetd start
/etc/init.d/httpd start
8）测试，安装一台新的虚拟机，配置BIOS启动引导为pxe方式
