（說明：系統鏡像：[紅帽企業.Linux.5].rhel-5.2-server-i386-dvd.iso）

1、掛載鏡像

[root@linux01 ~]# ls -al /media

total 16

drwxr-xr-x 2 root root 4096 Oct 11 2006 .

drwxr-xr-x 24 root root 4096 May 31 19:57 ..

[root@linux01 ~]# mkdir /media/cdrom

[root@linux01 ~]# ls -al /media

total 24

drwxr-xr-x 3 root root 4096 May 31 20:11 .

drwxr-xr-x 24 root root 4096 May 31 19:57 ..

drwxr-xr-x 2 root root 4096 May 31 20:11 cdrom

[root@linux01 ~]# mount -t iso9660 /dev/cdrom /media/cdrom # 掛載鏡像

mount: block device /dev/cdrom is write-protected, mounting read-only

[root@linux01 ~]#

2、安裝DHCP軟件包

[root@linux01 ~]# cd /media/cdrom/Server # 進入rmp軟件包文件夾

[root@linux01 Server]# ls -l dhcp*

-rw-r--r-- 243 root root 895219 Apr 16 2008 dhcp-3.0.5-13.el5.i386.rpm

-rw-r--r-- 263 root root 133868 Apr 16 2008 dhcp-devel-3.0.5-13.el5.i386.rpm

-rw-r--r-- 91 root root 194686 Apr 26 2008 dhcpv6-1.0.10-4.el5.i386.rpm

-rw-r--r-- 91 root root 122618 Apr 26 2008 dhcpv6-client-1.0.10-4.el5.i386.rpm

[root@linux01 Server]# rpm -ivh dhcp-3.0.5-13.el5.i386.rpm # i安裝 v 詳細輸出 h進度

warning: dhcp-3.0.5-13.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:dhcp ########################################### [100%]

[root@linux01 Server]#

[root@linux01 Server]# rpm -qa | grep dhcp # 查看與dhcp相關的安裝軟件

dhcpv6-client-1.0.10-4.el5

dhcp-3.0.5-13.el5

[root@linux01 Server]#

3、配置/etc/dhcpd.conf文件

[root@linux01 ~]# vi /etc/dhcpd.conf

#

# DHCP Server Configuration file.

# see /usr/share/doc/dhcp*/dhcpd.conf.sample

#

ddns-update-style interim; # dhcpd啟動的必須項

default-lease-time 21600; # 默認租約時間（sec）（6小時）

max-lease-time 43200; # 最大租約時間（sec）（12小時）

option domain-name "benet.com.cn"; # 主機所在域名，可選項

option domain-name-servers 222.172.200.68,202.203.144.33; # DNS域名服務器的ip，可選項

subnet 192.168.7.0 netmask 255.255.255.0 {

range 192.168.7.50 192.168.7.250;

option subnet-mask 255.255.255.0;

option broadcast-address 192.168.7.255;

option routers 192.168.7.1;

host linux01{????? # 靜態ip

hardware ethernet 00:0C:29:BE:87:75;

fixed-address 192.168.7.2;

}

}

~

~

"/etc/dhcpd.conf" 15L, 383C written

[root@linux01 ~]# service dhcpd restart

Shutting down dhcpd: [ OK ]

Starting dhcpd: [ OK ]

[root@linux01 ~]#

4、查看DHCP本機網絡情況

[root@linux01 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0 # 網卡信息

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

DEVICE=eth0

BOOTPROTO=static

BROADCAST=192.168.7.255

HWADDR=00:0C:29:BE:87:75

IPADDR=192.168.7.2

NETMASK=255.255.255.0

NETWORK=192.168.7.0

ONBOOT=yes

~

~

[root@linux01 ~]#

[root@linux01 network-scripts]# vi /etc/sysconfig/network # 主機名和網關信息

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=linux01

GATEWAY=192.168.7.1~

~

[root@linux01 ~]#

[root@linux01 etc]# cat hosts # 本機信息

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 linux01 localhost.localdomain localhost # 主機名主機名.域名主機別名

::1 localhost6.localdomain6 localhost6

[root@linux01 etc]#

[root@linux01 etc]# cat hosts # 域名解析服務信息

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 linux01 localhost.localdomain localhost

::1 localhost6.localdomain6 localhost6

[root@linux01 etc]#

說明：在linux安裝時有配置好以上項目時，在下面路徑下也有這些信息及配置

[root@linux02 ~]# cd /etc/sysconfig/networking/profiles/default

[root@linux02 default]# ls

hosts ifcfg-eth0 network resolv.conf

[root@linux02 default]#

5、客戶端獲取ip

Linux客戶端

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # 客戶端網絡配置

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

DEVICE=eth0

BOOTPROTO=dhcp # 使用dhcp自動獲取

HWADDR=00:0C:29:CD:40:C8

ONBOOT=yes

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

[root@localhost ~]#

[root@linux01 ~]# /etc/init.d/network restart # 重啟網絡

客戶端Xp系統ip地址自動獲取驗證

<?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" />

6、DHCP相關命令

[root@linux01 ~]# rpm -qa dhcpd # 查詢當前系統安裝的dhcp包

[root@linux01 ~]# rpm -qa dhcp*

dhcpv6-client-1.0.10-4.el5

dhcp-3.0.5-13.el5

[root@linux01 ~]#

[root@linux01 ~]# service dhcpd status # 查看當前dhcp服務狀態

dhcpd (pid 12946) is running...

[root@linux01 ~]#

[root@linux01 ~]# service dhcpd start/stop/restart # 開啟/停止/重啟dhcp服務

[root@linux01 ~]# chkconfig --list | grep dhcpd # 查看dhcpd的服務在不同模式下的狀態

dhcpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off

[root@linux01 ~]# chkconfig --level 35 dhcpd on # 配置dhcpd服務在35系統模式下為自動隨機開啟

[root@linux01 ~]#
