详细说明参考：

（三）跟我一起玩Linux网络服务：DHCP服务配置之主服务器配置

 

#! /bin/bash
IPSAG="10.10.10"

DN="ns.gr.org"
cat  >  /etc/dhcpd.conf << +END+

ignore client-updates;
subnet $IPSAG.0 netmask 255.255.255.0 {
        option routers                  $DNSIP;
        option subnet-mask              255.255.255.0;
        option domain-name              "$DN";

        option time-offset              28800;
        range dynamic-bootp $IPSAG.100 $IPSAG.200;

                fixed-address 207.175.42.188;
        }
}
+END+
service dhcpd restart
ps -ax | grep dhcpd
