使用PXE協議遠程安裝LINUX

OS: REDHAT AS 3.X 1 安裝tftp和dhcp 服務器 # rpm -ivh tftp-server-0.39-0.EL3.1.c0.i386.rpm # rpm -ivh dhcp-3.0.1-10_EL3.i386.rpm 2 配置tftp和dhcp服務器 # vi /etc/xinetd.d/tftp =============+==========+===========+============+============

OS: REDHAT AS 3.X

1 安裝tftp和dhcp服務器

# rpm -ivh tftp-server-0.39-0.EL3.1.c0.i386.rpm
# rpm -ivh dhcp-3.0.1-10_EL3.i386.rpm

2 配置tftp和dhcp服務器

# vi /etc/xinetd.d/tftp
=============+==========+===========+============+============
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
}
=============+==========+===========+============+============

# cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf
# vi /etc/dhcpd.conf
=============+==========+===========+============+============
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";
}
=============+==========+===========+============+============

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

# cd /tftpboot
# mkdir pxelinux.cfg

# vi default
=============+==========+===========+============+============
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
=============+==========+===========+============+============

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
