在xuegod74上设置网卡dhcp动态获取ip

BOOTPROTO=dhcp

重启网卡

service network restart

测试

nslookup

Server:192.168.137.73

Address:192.168.137.73#53

Name:

Address: 192.168.137.165

在xuegod73上查看

ls /var/named/

chroot

data ost -local

dynamic ck -network

slaves

#为临时文件15分钟后同步给文件

其他客户端重启网络服务，查看DHCP分配信息，发现已经有了set相关字段

tail -n 15 /var/lib/dhcpd/

server-duid "035031T007000014)j301323";

lease 192.168.137.165 {

set ddns-rev-name = ".";

set ddns-fwd-name = "";

client-hostname "xuegod74";

}

15分钟后查看和两个文件
