debian+pxe 最主要的是preseed 文件的的配置，其他的基本没有什么难度。具体如下：

apt-get install apt-cacher-ng apache2

vim /etc/apt-cacher-ng/backends_debian
http://mirrors.163.com/debian/

cat /etc/default/tftpd-hpa
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure"

vi /etc/dhcp/dhcpd.conf
subnet 192.88.50.0 netmask 255.255.255.0 {
range 192.88.50.200 192.88.50.253;
option domain-name-servers 192.88.50.42;
option routers 192.88.50.1;
default-lease-time 600;
max-lease-time 7200;
next-server 192.88.50.46;
filename "pxelinux.0";
}

mkdir /var/lib/tftpboot
cd /var/lib/tftpboot
wget http://ftp.fr.debian.org/debian/dists/wheezy/main/installer-amd64/current/images/netboot/debian-installer/amd64/pxelinux.0
