公司每月新增几十台服务器，一台一台安装，实在是太累，通过以下方法，很容易在1小时内将60台系统安装好。
环境：
192.168.5.112 dhcp server,Ubuntu 10.04
192.168.5.150-200 dhcp client,pxe boot
所有配置在192.168.5.112上进行
1.安装dnsmasq
apt-get install dnsmasq
2.配置dnsmasq
vi /etc/dnsmasq.conf
bogus-priv
filterwin2k
interface=eth0
dhcp-range=192.168.5.150,192.168.5.250,12h
dhcp-boot=pxelinux.0
enable-tftp
tftp-root=/var/ftpd
dhcp-authoritative
3.安装apache2并建立相关目录
apt-get install apache2
mkdir /var/www/Ubuntu
mount -o loop ~/Ubuntu10.04.iso /mnt
cp /mnt/preseed/Ubuntu-server.seed /var/www/ubuntu
cp -a /mnt/* /var/www/Ubuntu
cp -r /mnt/install/netboot/* /var/ftpd/
4.修改pxe配置
vi /var/ftpd/pxelinux.cfg/default
label linux
kernel Ubuntu-installer/amd64/linux
append ks=http://192.168.5.112/Ubuntu/ks.cfg preseed/url=http://192.168.5.112/ubuntu/ubuntu-server.seed vga=normal initrd=ubuntu-installer/amd64/initrd.gz –
5.修改ks.cfg
vi ks.cfg

#network –bootproto=dhcp –device=eth0
network –bootproto=static –ip=192.168.5.168 –netmask=255.255.255.0 –gateway=192.168.5.112 –nameserver=221.5.88.88 –device=eth0
firewall –disabled
skipx
%packages
@openssh-server
注：
生成密码
echo gaojinbo.com | openssl passwd -1 -stdin
6.修改Ubuntu-server.seed配置
vi Ubuntu-server.seed
# Suggest LVM by default.
d-i partman-auto/init_automatically_partition string some_device_lvm
d-i partman-auto/init_automatically_partition seen false
# Always install the server kernel.
d-i base-installer/kernel/override-image string linux-server
# Install the Ubuntu Server seed.
tasksel tasksel/force-tasks string server

# Only ask the UTC question if there are other operating systems installed.
d-i clock-setup/utc boolean false
d-i clock-setup/ntp boolean false
d-i apt-setup/use_mirror boolean false
d-i netcfg/get_ipaddress string 127.0.0.1
d-i mirror/http://hostname string 127.0.0.1
d-i apt-setup/restricted boolean false
# No boot splash screen.
d-i debian-installer/splash boolean false
