Ubuntu_PXE_Install

                参考文章  http://wiki.koeln.ccc.de/index.php/Ubuntu_PXE_Install 翻译了一下，第一次翻译，而且英语不是很好，所以也只能翻译个大概了……呵呵……不过应该是可以看懂的Install servicestftpd-hpa
dhcp3-server
netkit-inetd
  准备tftp server
修改配置文件/etc/inetd.conf如下：
tftp           dgram   udp     wait    root  /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
sudo update-inetd --enable BOOT
别忘了创造tftp 目录 /var/lib/tftpboot  （如果没的话）
在Ubuntu 6.06 Server (或者 /etc/inetd.conf 不存在) 可以编辑 /etc/default/tftpd-hpa:
RUN_DAEMON="yes"
OPTIONS="-l -s /var/lib/tftpboot"
Prepare your dhcp-server根据实际修改：
If you have a working dhcp server add the following lines to your group, substituting ip and mac address as needed
host pxeinstall {
  hardware ethernet [网卡地址 不要方括号];
  fixed-address 10.0.0.16;
  next-server [tftp的IP地址];
  filename "pxelinux.0";
}
The following simpler file may also work in a trivial environment
subnet 0.0.0.0 netmask 0.0.0.0 {
  range 192.168.0.1 192.168.0.2;
  filename "pxelinux.0";
}
Get the files获取文件All the files you need are on the install media, or you can get them here:
hoary 5.04

warty 5.10

breezy 5.10
dapper 6.06
edgy 6.10
所有需要的在安装媒体上  或者从这些连接取得各个ubuntu的版本
把netboot 文件放进 /tftpboot 目录
lftp -c "open
http://archive.ubuntu.com/ubuntu/dists/dapper/main/installer-i386/current/images/
; mirror netboot/"
cp -a netboot/* /var/lib/tftpboot
# untar the pxeboot.tar.gz
cd /var/lib/tftpboot/
tar xfz pxeboot.tar.gz
pxe bootloader config
Edit or patch pxelinux.cfg/default .（编辑pxelinux.cfg/default如下：）

Make a symlink from default to the ip of the pxe boot client.
cd /tftpboot/pxelinux.cfg
ln -s default 0A000010

Should look like this:应该如下所示：

/tftpboot/pxelinux.0
/tftpboot/initrd.gz

Start the PXE client
Just boot up the computer that will use DHCP and then PXE to get the
images,启动电脑应该是没问题了哈 if something isn't working you can use a sniffer on your
install server to check.
tethereal -R bootp
#tethereal -VR bootp
tethereal port tftp
tcpdump -n
Setup a mirror做自己的ubuntu镜象
Download apt-mirror and write a configuration file eg.:下载镜像文件及配置：
set base_path      /usr/local/ubuntu/mirror
deb http://gb.archive.ubuntu.com/ubuntu/ dapper main restricted
deb http://gb.archive.ubuntu.com/ubuntu/ dapper main/debian-installer
deb http://gb.archive.ubuntu.com/ubuntu/ dapper main restricted/debian-installer
Create a 'var' and 'skel' directory under your chosen base path（创造var和skel目录在自己选择的路径下）
Run apt-mirror against the configuration file which you've
created. （再apt-mirror一次）This will replicate the ubuntu mirror to your chosen base path
(you will need to create the soft links to the dists and pool
directories yourself) eg.:
~$ ls -al /usr/local/ubuntu/mirror
total 24
drwxr-xr-x   5 root root   4096 May 18 12:46 .
drwxrwxrwx  11 root root   4096 May 18 12:27 ..
lrwxrwxrwx   1 root root   34 May 18 12:46 dists -> gb.archive.ubuntu.com/ubuntu/dists
drwxr-xr-x   3 root root   4096 May 18 12:46 gb.archive.ubuntu.com
lrwxrwxrwx   1 root root   33 May 18 12:46 pool -> gb.archive.ubuntu.com/ubuntu/pool
drwxr-xr-x   3 root root   4096 May 18 10:53 skel
drwxr-xr-x   2 root root   8192 May 18 13:27 var
Serve the /usr/local/ubuntu directory out with apache
When you boot the ubuntu network installer, point it at the ip address and the 'mirror' directory
