最近研究kickstart启动，来一篇centos装ubuntu12的文档共享给大家，供大家参考。是经过本人反复测试完善的。
centos6.2 with kickstart网络启动自动安装Ubuntu 12.04(vsftpd+DHCP+TFTP)

#在网络启动的centos服务器上安装kickstart所需软件（如果用dnsmasq+httpd的话，会方便很多，且易于管理；因为dnsmasq=dhcp+tftp+xinetd）
yum install dhcp tftp* xinetd vsftpd
或
yum install -y dnsmasq
vim /etc/dnsmasq.conf把如下行注释去掉并修改
bogus-priv
filterwin2k
dhcp-range=192.168.44.100,192.168.44.120,12h
dhcp-boot=pxelinux.0
enable-tftp
tftp-root=/var/lib/tftpboot
dhcp-authoritative
#以下是使用vsftpd+DHCP+TFTP的情形
#启用tftp
sed -i '/disable/s/yes/no/g' /etc/xinetd.d/tftp
将/var/lib/tftpboot链接到/tftpboot
ln -s /var/lib/tftpboot /tftpboot
挂载光盘镜像并复制网启文件到tftp
mkdir /mnt/cd
mount -o loop -t auto ~/iso/ubuntu-12.04.4-server-amd64.iso /mnt/cd
cp -rv /mnt/cd/install/netboot/* /tftpboot
修改启动菜单
vim /tftpboot/pxelinux.cfg/default
将timeout后的0改成30表示3秒自动选择
vim /tftpboot/ubuntu-installer/amd64/boot-screens/txt.cfg
修改label cli上面的那行，改成下面这样
append initrd=ubuntu-installer/amd64/initrd.gz ks=ftp://192.168.44.250/pub/ks/ubuntuserver12/ks.cfg live-installer/net-image=ftp://192.168.44.250/pub/ks/ubuntuserver12/install/filesystem.squashfs
在ftp目录中放上安装源
mkdir -p /var/ftp/pub/ks/ubuntuserver12
cp -rv /mnt/cd/* /var/ftp/pub/ks/ubuntuserver12
配置dhcp
vim /etc/dhcp/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
next-server 192.168.44.250;
filename "pxelinux.0";
allow booting;
allow bootp;
subnet 192.168.44.0 netmask 255.255.255.0 {
# — default gateway
option routers 192.168.44.1;
option subnet-mask 255.255.255.0;
# option nis-domain “domain.org”;
option domain-name "chaoxing.com";
option domain-name-servers 202.106.195.68;
option time-offset -18000; # Eastern Standard Time
range 192.168.44.100 192.168.44.120;
}
编写ks.cfg文件
vim /var/ftp/pub/ks/ubuntuserver12/ks.cfg
# ubuntuser kickstart file
install
url --url ftp://192.168.44.250/pub/ks/ubuntuserver12

#不管是传统分区方式还是自动lvm分区方式，当遇到硬盘本身带有lvm分区的时候依然会需要人为干预，这个问题我至今还没有解决，官方好像没有打算修复这个“bug”。目前我是使用再次创建一个全新的lvm覆盖老lvm的方式强制跳过那交互的。如下
bootloader --location=mbr
zerombr yes
clearpart --drives=sda --initlabel --all
# 不设置swap时安装过程中会提示要不要重新添加swap分区
part swap --size 4096
part /boot --fstype ext4 --size=256
part pv.01 --size=1 --grow
volgroup vg pv.01
logvol / --vgname=vg --size=1 --grow --name=lv
#用以下ubuntu kickstart seed文件的内容，可让live-installer使用默认lvm的分区方式

启动各项服务
/etc/init.d/dhcpd restart && /etc/init.d/xinetd restart && /etc/init.d/vsftpd restart
注意
如果使用kickstart方式必须用“ks=”指出ks文件位置，不能用“file=；如果要使用seed文件（就是内容是d-i开头那种），需要使用“preseed/url=”指出seed文件位置，且必须与ks格式文件配合使用不能没有“ks=”只有“preseed/url=”
以下seed文件可供参考也可以没有，是配合ks文件扩展使用的，如果需要追加seed文件，把txt.cfg中append后改成
append initrd=ubuntu-installer/amd64/initrd.gz ks=ftp://192.168.44.250/pub/ks/ubuntuserver12/ks.cfg live-installer/net-image=ftp://192.168.44.250/pub/ks/ubuntuserver12/install/filesystem.squashfs preseed/url=ftp://192.168.44.250/pub/ks/ubuntuserver12/ks.seed

注意很多人在kickstart安装ubuntu时候出现这个如图的错误，
原因是在pxe启动的menu文件里append这行没有加上live-installer/net-image=ftp://192.168.44.250/pub/ks/ubuntuserver12/install/filesystem.squashfs，且
ks文件里没有写这样一行d-i live-installer/net-image string ftp://192.168.44.250/pub/ks/ubuntuserver12/install/filesystem.squashfs
