PXE远程安装linux系统

OS： REDHAT AS 3.X
1 安装tftp和dhcp服务器
[code]# rpm -ivh tftp-server-0.39-0.EL3.1.c0.i386.rpm
# rpm -ivh dhcp-3.0.1-10_EL3.i386.rpm[/code]
2 配置tftp和dhcp服务器
[code]# vi /etc/xinetd.d/tftp[/code]
=============+==========+===========+============+============
[code]service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -u nobody -s /tftpboot
per_source = 11
cps = 100 2
flags = IPv4
}[/code]
=============+==========+===========+============+============
[code]# cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf
# vi /etc/dhcpd.conf[/code]
=============+==========+===========+============+============
[code]option domain-name "systeng.net";
default-lease-time 6000;
max-lease-time 11400;
authourtative;
ddns-update-style ad-hoc;
log-facility local7;
subnet 192.168.10.0 netmask 255.255.255.0{
range 192.168.10.150 192.168.10.155;
option domain-name-servers 202.99.160.68;
option domain-name "systeng.net";
option netbios-name-servers 192.168.10.1;
option routers 192.168.10.1;
option broadcast-address 192.168.10.255;
default-lease-time 6000;
max-lease-time 11400;
filename "/pxelinux.0";
}[/code]
=============+==========+===========+============+============
3 配置支持PXE
[code]# mkdir /tftpboot
# cp /usr/lib/syslinux/pxelinux.0 /tftpboot[/code]
把LINUX第一张安装光盘上/image/pxeboot/initrd.img和vmlinuz 以及isolinux/*.msg考到/tftpboot目录下
[code]# cd /tftpboot
# mkdir pxelinux.cfg
# vi default[/code]
=============+==========+===========+============+============
[code]default
prompt 1
timeout 30
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
F7 snake.msg
label local
localboot 0
label linux
kernel vmlinuz
append initrd=initrd.img devfs=nomount ramdisk_size=9216
label text
kernel vmlinuz
append initrd=initrd.img text devfs=nomount ramdisk_size=9216
label expert
kernel vmlinuz
append expert initrd=initrd.img devfs=nomount ramdisk_size=9216
label ks
kernel vmlinuz
append ks initrd=initrd.img devfs=nomount ramdisk_size=9216
label nofb
kernel vmlinuz
append initrd=initrd.img devfs=nomount nofb ramdisk_size=9216
label lowres
kernel vmlinuz
append initrd=initrd.img lowres devfs=nomount ramdisk_size=9216
kernel vmlinuz[/code]
=============+==========+===========+============+============
4 配置NFS服务
[code]# vi /etc/exports
/home/iso/ 192.168.10.0/24(ro,sync)
# mkdir /home/iso[/code]
拷贝安装LINUX的ISO文件到这个目录
5 需要开启的系统服务
[code]/dhcpd/network/nfs/portmap/syslog/tftp/xinetd/[/code]
6 硬件需求
网卡上需要添加PXE远程启动芯片
