包准备：xinetd，tftp-server，dhcp，httpd，system-config-kickstart，syslinux，nfs
试验环境：
本机地址：192.168.46.98
本地网关：192.168.46.254
配置DHCP服务器：
Sample:
--------------------------------------------------------------------------------
subnet 192.168.46.0 netmask 255.255.255.0 {
range 192.168.46.100 192.168.46.105;
option routers 192.168.46.254;
default-lease-time 600;
max-lease-time 7200;
next-server 192.168.46.98; /*指向tftp服务器*/
filename="pxelinux.0"; ｝ /*ftp根目录的相对路径*/
--------------------------------------------------------------------------------
参考文件：
ddns-update-style interim; /*dhcp支持的dns动态更新方式*/
ignore client-updates; /*忽略客户端DNS动态更新*/
authoritative; /*授权*/
allow booting; /*支持PXE启动*/
allow bootp; /*支持boottp*/
subnet 192.168.129.0 netmask 255.255.255.0 { /*作用域*/
range 192.168.129.30 192.168.129.78; /*ip地址段范围*/
option routers 192.168.129.1; /*网关*/
option subnet-mask 255.255.255.0; /*子网掩码*/
option domain-name-servers 203.103.24.68; /*DNS服务器的地址*/
default-lease-time 21600; /*租期，秒数*/
max-lease-time 43200; /*最大租期，秒数*/
next-server 192.168.129.22; /*TFTPServer的IP*/
filename "/pxelinux.0"; /*Bootstrap文件*/
挂载系统光盘到 /mnt
配置TFTP根目录（tftpboot）
# cp /mnt/images/pxeboot/vmlinuz /mnt/images/pxeboot/initrd.img /var/lib/tftpboot
# cp /mnt/isolinux/boot.msg /mnt/isolinux/splash.jpg /var/lib/tftpboot
# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
# mkdir /var/lib/tftpboot/pxelinux.cfg
# cp -p /media/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
TFTP下default配置
# vi /var/lib/tftpboot/pxelinux.cfg/default
--------------------------------------------------------------------------------

KS文件参考：
开启服务
tftp包含于xinetd中，所以要进入配置文件中开启
# vi /etc/xinetd.d/tftp
