server1的配置
ifconfig eth0 172.17.17.23 netmask 255.255.255.0
route add default getway 172.17.17.1
yum install dhcp-*
cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf
vim /etc/dhcpd.conf

dhcp中继代理server1的配置
yum install dhcp-*
vim /etc/sysconfig/dhcrelay
INTERFACES="eth0 eth1 eth2"
DHCPSERVERS="172.17.17.23"
echo 1 >/proc/sys/net/ipv4/ip_forward
service dhcrelay start
客户端测试
linux的主机利用dhclient 设备名称 获取IP地址
dhclient -r 释放IP地址
windows的主机设网卡为自动获取
