1. 基础服务配置
yum install tftp-server dhcp http 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
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
} 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";
#next-server 192.168.1.13; #dhcp服务器地址
#filename "/pxelinux.0";
#}
next-server 192.168.1.13;   #PXE服务器IP地址
filename "/pxelinux.0";
subnet 192.168.1.0 netmask 255.255.255.0 {
# --- default gateway
option routers                192.168.1.13;
option subnet-mask              255.255.255.0;
option time-offset  -18000; # Eastern Standard Time
range dynamic-bootp 192.168.170.128 192.168.170.254;
default-lease-time 21600;
max-lease-time 43200;
group pxe {
host CentOS5-3 {
     next-server 192.168.170.51;
     hardware ethernet 08:00:27:B0:D6:37;
     fixed-address 192.168.170.53;
}
host CentOS5-2 {
     next-server 192.168.170.51;
     hardware ethernet 08:00:27:9c:6a:58;
     fixed-address 192.168.170.52;
}
}
}
2. 配置pxe引导文件 mkdir /tftpboot
cp /usr/lib/syslinux/pxelinux.0 /tftpboot
cd /var/www/html/centOS/image/pxeboot/
cp initrd.img vmlinux /tftpboot/
cp /var/www/html/centOS/isolinux/*.msg /tftpboot
cd /tftpboot; mkdir pxelinux.cfg
cp /var/www/html/centOS/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default

vi /tftpboot/pxelinux.cfg/default default linux
prompt 1
timeout 600
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
label linux
kernel vmlinuz
append ks=http://192.168.1.13/centOS/ks.cfg initrd=initrd.img devfs=nomount ramdisk_size=9216
label text
kernel vmlinuz
append initrd=initrd.img text
label ks
kernel vmlinuz
append ks initrd=initrd.img
label local
localboot 1
label memtest86
kernel memtest
append -
3安装kickstart配置文件生成工具
yum install system-config-kickstart
启动system-config-kickstart选择每一步的配置后，保存ks.cfg文件到/var/www/html/centOS/
vi /var/www/html/centOS/ks.cfg

没有测试redhat，网上说需要
vi /tftpboot/pxelinux.cfg/default
auth --useshadow --enablemd5
key --skip #这行一定要，跳过注册号输入
