步骤一、为服务器配置静态的IP地址
[root@localhost ~]# vim/etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
HWADDR=00:0c:29:c3:b1:d9
IPADDR=192.168.80.253
NETMASK=255.255.255.0
步骤二、配置DHCP服务器
1、安装软件包
[root@localhost ~]# rpm -q dhcp
package dhcp is not installed （dhcp软件包没有安装）
进入光盘文件安装dncp
[root@localhost ~]# cd /misc/cd/Server/
[root@localhost Server]#
查找dncp开通的文件
[root@localhost Server]# ls dhcp*
dhcp-3.0.5-31.el5_8.1.x86_64.rpm dhcpv6-1.0.10-20.el5.x86_64.rpm
dhcp-devel-3.0.5-31.el5_8.1.i386.rpm dhcpv6-client-1.0.10-20.el5.x86_64.rpm
dhcp-devel-3.0.5-31.el5_8.1.x86_64.rpm
安装dhcp软件包
[root@localhost Server]# rpm -ivhdhcp-3.0.5-31.el5_8.1.x86_64.rpm
warning: dhcp-3.0.5-31.el5_8.1.x86_64.rpm: Header V3 DSA signature:NOKEY, key ID 37017186

2、配置dhcp配置文件
让linux客户端获得固定的IP：192.168.80.188，win7客户端自动获取IP地址
[root@localhost ~]# vim /etc/dhcpd.conf
[root@localhost ~]# cat /etc/dhcpd.conf
ddns-update-style interim;
subnet 192.168.80.0 netmask 255.255.255.0 {
optionrouters 192.168.80.253;
optionsubnet-mask 255.255.255.0;
optiondomain-name "tarena.com";
optiondomain-name-servers 192.168.80.1,202.106.0.20;
rangedynamic-bootp 192.168.80.80 192.168.80.100;
range dynamic-bootp192.168.80.120 192.168.80.200;
default-lease-time21600;
max-lease-time43200;
host linux {
hardwareethernet 00:0C:29:B4:3D:3C;
fixed-address 192.168.80.188;
}
host ns {
hardware ethernet 12:34:56:78:AB:CD;
fixed-address 207.175.42.254;
}
}
3、启动服务
[root@localhost ~]# /etc/init.d/dhcpd configtest
Syntax: OK
[root@localhost ~]# /etc/init.d/dhcpd status
dhcpd 已停
[root@localhost ~]# /etc/init.d/dhcpd start
启动 dhcpd： [确定]
[root@localhost ~]# chkconfig --list dhcpd
dhcpd 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
[root@localhost ~]# chkconfig dhcpd on
[root@localhost ~]# chkconfig --list dhcpd
dhcpd 0:关闭 1:关闭 2:启用 3:启用4:启用 5:启用 6:关闭
4、验证
分别登录两台客户机查看ip地址的获取情况
Linux获取的IP地址是192.168.80.188.
