环境：
centos6.5
使用NAT联网
本机IP为：192.168.147.3
网关：192.168.147.2
具体设置nat联网访问：
http://www.apelearn.com/bbs/thread-14629-1-1.html

配置钱准备：
1.将防火墙及selinux关闭
serveice iptables stop
chkconfig iptables off
iptables -F
/etc/selinux/conf将改成SELINUX=disabled
2.测试能否上网

开始安装：

安装tftp tftp-server vsftp  syslinux system-config-kickstart dhcp

yum -y install tftp tftp-server vsftp  syslinux system-config-kickstart dhcp

1.配置dhcp
vim /etc/dhcp/dhcpd.conf

#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
# see 'man 5 dhcpd.conf'
#
ddns-update-style interim;
ignore client-updates;
allow booting;
allow bootp;
subnet 192.168.147.0 netmask 255.255.255.0 {
      option routers                192.168.147.2;
      option subnet-mask             255.255.255.0;
      option domain-name-servers    192.168.147.2;
      option time-offset             -18000; # Eastern Standard Time
      range dynamic-bootp 192.168.147.60 192.168.147.100;
      default-lease-time 21600;
      max-lease-time 43200;
      next-server 192.168.147.3;
      filename "pxelinux.0";
}
//说明一下，我的服务器IP为 192.168.2147.3，网关和dns都是192.168.2147.2 , 所以该配置文件中的相关配置请注意一下
启动服务：service dhcpd start

2.配置tftp-server（xinetd）
vim /etc/xinetd.d/tftp
更改disable为no

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
}

启动服务：service xinetd start

将光盘加载上虚拟机
3.准备内核、初始化镜像文件
cp /media/CentOS_6.5_Final/images/pxeboot/initrd.img /var/lib/tftpboot/
cp /media/CentOS_6.5_Final/images/pxeboot/vmlinuz /var/lib/tftpboot/
cp /media/CentOS_6.5_Final/isolinux/boot.msg splash.jpg vesamenu.c32 /var/lib/tftpboot/
cp -rf /media/CentOS_6.5_Final/* /var/ftp/pub/

4.准备PXE引导程序、启动菜单文件
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
mkdir /var/lib/tftpboot/pxelinux.cfg
cp /media/CentOS_6.5_Final/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

5.启动菜单配置
vim /var/lib/tftpboot/pxelinux.cfg/default
default centos6 //如果系统使用的是centos则改成centos6,必须和下面相对应
#prompt 1
timeout 60

display boot.msg

menu background splash.jpg
menu title Welcome to CentOS 6.5!
menu color border 0 #ffffffff #00000000
menu color sel 7 #ffffffff #ff000000
menu color title 0 #ffffffff #00000000
menu color tabmsg 0 #ffffffff #00000000
menu color unsel 0 #ffffffff #00000000
menu color hotsel 0 #ff000000 #ffffffff
menu color hotkey 7 #ffffffff #ff000000
menu color scrollbar 0 #ffffffff #00000000

label centos6 //和上面对应
  menu label ^Install or upgrade an existing system
  menu default
  kernel vmlinuz
  append initrd=initrd.img ks=ftp://192.168.147.3/pub/ks.cfg  //增加共享的文件目录
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 -

注意：由于default是复制过来的，所以本身的权限是只读，如果想修改则需要给该文件配置744权限
chmod 744 pxelinux.cfg/default

service xinetd restart
service dhcpd restart
service tftp restart
service vsftpd restart

在终端下运行system-config-kickstart进行生成ks.cfg文件
