使用PXE協議遠程安裝LINUX

1、安裝tftp和dhcp服務器

#rpm-ivhtftp-server-0.39-0.EL3.1.c0.i386.rpm

#rpm-ivhdhcp-3.0.1-10_EL3.i386.rpm

2、配置tftp和dhcp服務器

以下為引用的內容：
#vi/etc/xinetd.d/tftp
=============+==========+===========+============+============
servicetftp
{
disable=no
socket_type=dgram
protocol=udp
wait=yes
user=root
server=/usr/sbin/in.tftpd
server_args=-unobody-s/tftpboot
per_source=11
cps=1002
flags=IPv4
}
=============+==========+===========+============+============

#cp/usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample/etc/dhcpd.conf
#vi/etc/dhcpd.conf
=============+==========+===========+============+============
optiondomain-name"systeng.net";
default-lease-time6000;
max-lease-time11400;
authourtative;
ddns-update-stylead-hoc;
log-facilitylocal7;

subnet192.168.10.0netmask255.255.255.0{
range192.168.10.150192.168.10.155;
optiondomain-name-servers202.99.160.68;
optiondomain-name"systeng.net";
optionnetbios-name-servers192.168.10.1;
optionrouters192.168.10.1;
optionbroadcast-address192.168.10.255;
default-lease-time6000;
max-lease-time11400;
filename"/pxelinux.0";
}
=============+==========+===========+============+============
 

3、配置支持PXE

#mkdir/tftpboot

#cp/usr/lib/syslinux/pxelinux.0/tftpboot

把LINUX第一張安裝光盤上/image/pxeboot/initr.img和vmlinux以及isolinux/*.msg考到/tftpboot目錄下

以下為引用的內容：
#cd/tftpboot
#mkdirpxelinux.cfg

#videfault
=============+==========+===========+============+============
default
prompt1
timeout30
displayboot.msg
F1boot.msg
F2options.msg
F3general.msg
F4param.msg
F5rescue.msg
F7snake.msg
labellocal
localboot0
labellinux
kernelvmlinuz
appendinitrd=initrd.imgdevfs=nomountramdisk_size=9216
labeltext
kernelvmlinuz
appendinitrd=initrd.imgtextdevfs=nomountramdisk_size=9216
labelexpert

labellowres
kernelvmlinuz
appendinitrd=initrd.imglowresdevfs=nomountramdisk_size=9216
kernelvmlinuz
=============+==========+===========+============+============
 

4、配置NFS服務

#vi/etc/exports

/home/iso/192.168.10.0/24(ro,sync)

#mkdir/home/iso

拷貝安裝LINUX的ISO文件到這個目錄

5、需要開啟的系統服務

/dhcpd/network/nfs/portmap/syslog/tftp/xinetd/

6、硬件需求

網卡上需要添加PXE遠程啟動芯片
