linux下DHCP+PXE配置
2007-07-09 17:37
#一个简单的默认dhcp服务器配置文件/etc/dhcpd.conf
ddns-update-style interim;
subnet 172.16.0.0 netmask 255.255.255.0 {
range 172.16.0.10 172.16.0.253;
option routers 172.16.0.1;
option subnet-mask 255.255.255.0;
}
#配置dhcp服务器
###################################
#放在/etc/dhcpd.conf末尾就可以了
option space PXE;
option PXE.mtftp-ip code 1 = 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 192.168.1.246; //tftp服务器,可以和dhcp服务器不在同一个机器上
}
###################################
#打开tftp
chkconfig tftp --level 345 on
vi /etc/xinetd.d/tftp #看看内容,不用改
cd /tftpboot/
mkdir pxelinux.cfg
vi default
#######################
#default的内容如下
DEFAULT install
PROMPT 1
LABEL install FC5-x86
KERNEL vmlinuz
APPEND initrd=initrd.img devfs=nomount ramdisk_size=16384
#######################
拷贝光盘的/images/pxeboot/或者FC5/isolinux下面的initrd.img和vmlinuz到/tftpboot下,注意,必须用光盘上的,不能用硬盘的.
cp /usr/lib/syslinux/pxelinux.0 /tftpboot/
#启动tftp服务
/etc/init.d/xinetd restart
