1、需要安装的软件包：

apt-get install isc-dhcp-server tftpd-hpa syslinux

2、编辑dhcpd的配置文件 ，文件详细配置如下

root@xlcom:/tmp# vim /etc/dhcp/dhcpd.conf
option domain-name "example.org";
option domain-name-servers ns1.example.org, ns2.example.org;
allow booting;
allow bootp;
default-lease-time 600;
max-lease-time 7200;
   
log-facility local7;
   
# A slightly different configuration for an internal subnet.
subnet 152.24.0.0 netmask 255.255.0.0 {
  range 152.24.1.2 152.24.1.29;
  option domain-name-servers ns1.internal.example.org;
  option domain-name "internal.example.org";
  option routers 152.24.1.1;
  option subnet-mask 255.255.0.0;
  option broadcast-address 152.24.255.255;
  default-lease-time 600;
  max-lease-time 7200;
  next-server 152.24.1.1;
  filename "pxelinux.0";
}

复制pxelinux.0 到tftpboot目录上

cp /usr/lib/syslinux/pxelinux.0 /var/lib/tftpboot

3、

编写一个脚本，启动pxe安装服务，其中mount改成与自己的ks脚本里面设置的一样的就行了。

root@xlcom:/home/xianglou# vim startpxe.sh 
#!/bin/bash
   
ifconfig eth0 152.24.1.1
/etc/init.d/isc-dhcp-server start
mount /media/e/CentOS-6.4-i386-bin-DVD1.iso /home/xianglou/www/centos/6.3/64/ -o loop

4、

root@xlcom:~# cd /var/lib/tftpboot/
root@xlcom:~# mkdir pxelinux.cfg
root@xlcom:~# vim pxelinux.cfg/default
