网络安装Ubuntu

参考文章：http://www./bbs/showthread.php?t=178411
1，tftp部分：
下载http://download./down.php?id=20673&ResourceID=10322&site=1，tftp-hpa-0.42.tar.bz2
tar xvf
./configure --without-tcpwrapper
make && paco -lD "make install"
vi /etc/xinet.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -u nobody -s /tftpboot
disable = no
per_source = 11
cps = 100 2
}
:wq
mkdir /tftpboot
2,DHCP部分
我已经装好了DHCP，并且可以同了的，只要配置就行了
cp /etc/dhcpd.conf /etc/dhcpd.conf.orig
vi /etc/dhcpd.conf   删除原来的
option space PXE;
option PXE.mtftp-ip code 1 = ip-address;
option PXE.mtftp-cport code 2 = unsigned integer 16;
option PXE.mtftp-sport code 3 = unsigned integer 16;
option PXE.mtftp-tmout code 4 = unsigned integer 8;
option PXE.mtftp-delay code 5 = unsigned integer 8;
option PXE.discovery-control code 6 = unsigned integer 8;
option PXE.discovery-mcast-addr code 7 = ip-address;

class "pxeclients" {
match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
option vendor-class-identifier "PXEClient";
vendor-option-space PXE;

# At least one of the vendor-specific PXE options must be set in
# order for the client boot ROMs to realize that we are a PXE-compliant
# server. We set the MCAST IP address to 0.0.0.0 to tell the boot ROM
# that we can‘t provide multicast TFTP (address 0.0.0.0 means no
# address).

option PXE.mtftp-ip 0.0.0.0;

# This is the name of the file the boot ROMs should download.
filename "pxelinux.0";

# This is the name of the server they should get it from.
next-server 192.168.0.1;
}
ddns-update-style interim;
ignore client-updates;
default-lease-time 1200;
max-lease-time 9200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
option routers 192.168.0.254;
option domain-name-servers 192.168.0.1,192.168.0.2;
option domain-name "mydomain.org";
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.10 192.168.0.100;
}
host q10 {
hardware ethernet 00:00:F0:6B:38:5B;
fixed-address 192.168.0.22;
}
当然这里要修改地址信息，和MAC地址信息
3，用我机器上的ubuntu5.10中netboot下面的i386下面的内容拷贝到/tftpboot下面，里面有网络启动所需要的pxelinux.0，linux，initrd
修改/tftpboot/pxelinux.cfg/default，如下模样
DEFAULT install
PROMPT 1
LABEL install
KERNEL vmlinuz
APPEND initrd=initrd.img devfs=nomount ramdisk_size=16384
4，启动Vmware，网络启动，F12，然后居然出来了
boot：  回车
Loading linux 。。。。。。
Loading initrd.gz..............
然后待会还是出现Kernel Panic....,说要附加一个 root=  选项，不能mount 根文件系统
艾，这是刚才被我删掉的了，只好跟着添上，现在是
append vga=normal initrd=initrd.gz ramdisk_size=16432 root=/dev/rd/0 rw  --
这回可以了，就象我记得的以前装这个Ubutu时一样，启动Frame Buffer，在问我问题了，哈哈
然后我设置了代理什么的，还设置了ubutu的镜像站点，然后就开始自己安装了，我顶它个肺啊
