RHEL5.6搭建DHCP服务跟DHCP中继代理服务

 DHCP服务器上配置IP地址、netmask及gateway

eth0的IP:172.17.17.2

netmask:255.255.255.0

gateway:172.17.17.1

安装DHCP包

yum install dhcp-*

然后就是配置DHCP文件了

vim /etc/dhcpd.conf

ddns-update-style none;

option subnet-mask 255.255.255.0;

subnet 172.17.17.0 netmask 255.255.255.0 {

option routers 172.17.17.1;

range 172.17.17.20 172.17.17.254;

}

subnet 192.168.1.0 netmask 255.255.255.0 {

option routers 192.168.1.1;

range 192.168.1.20 192.168.1.254;

}

subnet 192.168.2.0 netmask 255.255.255.0 {

option routers 192.168.2.1;

range 192.168.2.20 192.168.2.254;

}

host zmy {

hardware ethernet 00:0C:29:62:79:74;

fixed-address 172.17.17.5;

}

这样DHCP的配置文件就写完了，接下来就是启动它

service dhcpd start

接下来是配置DHCP中继代理服务器，第一步同样是配置IP地址、netmask即可

eth0     IP:172.17.17.1      netmask:255.255.255.0

eth1     IP:192.168.1.1       netmask:255.255.255.0

eth2     IP:192.168.2.1       netmask:255.255.255.0

配置完成在中继代理服务器上安装DHCP包

yum install dhcp-*

然后就是配置简单的DHCP中继代理的配置文件了

vim /etc/sysconfig/dhcrelay

INTERFACES="eth0 eth1 eth2"

DHCPSERVER="172.17.17.2"

接下来就是启动DHCP中继代理服务

service dhcrelay start

接下来就是用客户端测试了~~~
