准备

1. 安装好 Ubuntu 14.04 系统的机器
2. 支持DHCP的路由器一个
3. 支持pxe启动的目标机器
4. Ubuntu机器和目标机器已经通过交换机连到同一个网络

配置网卡

/etc/network/interfaces

# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.20
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 8.8.8.8

重启网络服务

sudo /etc/init.d/networking restart

这一步未必起效。ifconfig 命令可能ip没有改变， 可以从 System Settings –> Network –> 去设置静态IP
由于配置静态IP了，可能会导致无法连接外网。配置网络可以等到apt-get install的步骤之后来配置。或者Ubuntu的机器配置双网卡，一个连接外网，另一个连接交换机。

安装DHCP， TFTP，PXE,NFS 服务

sudo apt-get update
sudo apt-get install isc-dhcp-Server inetutils-inetd tftpd-hpa syslinux nfs-kernel-Server

配置DHCP

/etc/default/dhcp-server

INTERFACES="eth0"

/etc/dhcp/dhcpd.conf

default-lease-time 600;
max-lease-time 7200;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.21 192.168.1.240;
option subnet-mask 255.255.255.0;
option routers 192.168.1.20;
option broadcast-address 192.168.1.255;
filename "pxelinux.0";
next-Server 192.168.1.20;
}

重启DHCP服务

sudo /etc/init.d/isc-dhcp-server start

配置TFTP服务

/etc/inetd.conf

tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot

/etc/default/tftpd-hpa

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS="[:0.0.0.0:]:69"
TFTP_OPTIONS="--secure"
RUN_DAEMON="yes"
OPTIONS="-l -s /var/lib/tftpboot"

开机启动 tftp

sudo update-inetd --enable BOOT
sudo service tftpd-hpa start

检查状态

sudo netstat -lu | grep tftp

配置pxe 启动文件

sudo mkdir /var/lib/tftpboot
sudo mkdir /var/lib/tftpboot/pxelinux.cfg
sudo mkdir -p /var/lib/tftpboot/Ubuntu/14.04/amd64/
sudo cp /usr/lib/syslinux/vesamenu.c32 /var/lib/tftpboot/
sudo cp /usr/lib/syslinux/pxelinux.0 /var/lib/tftpboot/

添加启动镜像

1.下载镜像

sudo wget http://releases.ubuntu.com/14.04/ubuntu-14.04.3-desktop-amd64.iso

2.挂载

sudo mount -o loop /mnt/ubuntu-14.04.3-desktop-amd64.iso /media/
sudo cp -r /media/* /var/lib/tftpboot/Ubuntu/14.04/amd64/
sudo cp -r /media/.disk /var/lib/tftpboot/Ubuntu/14.04/amd64/
sudo cp /media/casper/initrd.lz /media/casper/vmlinuz /var/lib/tftpboot/Ubuntu/

配置nfs

/etc/exports

/var/lib/tftpboot/Ubuntu/14.04/amd64 *(ro,async,no_root_squash,no_subtree_check)

重启nfs服务

sudo /etc/init.d/nfs-kernel-server start

安装

1. 要在目标机器上 设置pxe启动。 现在的机器一般都支持pxe启动

kickstart 自动安装
