Linux下DHCP服务端的配置
[root@loaclhost /]mount /dev/hdc /hdc //挂载光盘到/dev/
[root@loaclhost /]cd hdc/Server //进入关盘的Server目录
[root@loaclhost Server]rpm –ivh dhcp-3.0.5-7.el5.i386.rpm //rpm安装DHCP的服务器端
[root@loaclhost Server]cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf // 将/etc/dhcpd.conf替换成/usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample
//小提示：DHCP服务器默认情况下是没有配置文件的，需要从/usr目录下复制样本，然后再进行修改，如果是熟练的工程师，可以直接创建。
[root@loaclhost Server]cd /etc
[root@loaclhost etc]vi dhcpd.conf
