1、一、设置好LinuxDHCP服务器的IP地址[root@localhost~]#vi/etc/sysconfig/network-scripts/ifcfg-eth0[root@localhost~]#servicenetworkrestart正在关闭接口eth0：[确定]关闭环回接口：[确定]弹出环回接口：[确定]弹出界面eth0：[确定][root@localhost~]#ifconfigeth0Linkencap:EthernetHWaddr00:0C:29:FF:17:BEinetaddr:192.168.1.2Bcast:192.168.1.255Mask:255.255

2、.255.0inet6addr:fe80::20c:29ff:feff:17be/64Scope:LinkUPBROADCASTRUNNINGMULTICASTMTU:1500Metric:1RXpackets:195errors:0dropped:0overruns:0frame:0TXpackets:112errors:0dropped:0overruns:0carrier:0collisions:0txqueuelen:1000RXbytes:31540(30.8KiB)TXbytes:21507(21.0KiB)Interrupt:67Baseaddress:0x2024二

3、、查看是否安装有DHCP[root@localhost~]#rpm-qa

4、grepdhcpdhcpv6-client-1.0.10-17.el5一、安装DHCP1.挂载光盘为DHCPCD[root@localhost~]#mkdirdhcpcd[root@localhost~]#mount/dev/cdromdhcpcdmount:blockdevice/dev/cdromiswrite-protected,mountingread-only安装DHCP[root@localhost~]#rpm-ivhdhcpcd/Server/dhcp-3.0.5-21.el5.i386.rpm

5、warning:dhcpcd/Server/dhcp-3.0.5-21.el5.i386.rpm:HeaderV3DSAsignature:NOKEY,keyID37017186Preparing...###########################################[100%]1:dhcp###########################################[100%][root@localhost~]#rpm-qa

6、grepdhcpdhcpv6-client-1.0.10-17.el5dhcp-3.0.5-21.el5四、配置DHCP文件进入

7、/etc/dhcpd.conf的文件为空，进行复制[root@localhost~]#cp/usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample/etc/dhcpd.confcp：是否覆盖“/etc/dhcpd.conf”?y[root@localhost~]#vi/etc/dhcpd.conf设置域名myjiho.com网关192.168.1.1子网掩码255.255.255.0IP地址池范围192.168.1.22192.168.1.100重启DHCP四、设置客户端为自动获取释放IP更新IP实验成功
