1 配置DHCP服务器IP
ifconfig eth0 10.10.1.10
ifconfig eth0:1 10.10.1.1
ifconfig eth0:2 172.168.1.1
ifconfig eth0:3 172.168.2.1
2 DHCP相关设置
windows → 网络共享中心 → 属性 → 更改适配器设置 → vmnet1 → 属性 → IPV4 → 开启DHCP
vmware → 编辑 → 虚拟网络编辑 → 勾选使用本地DHCP
3 配置主配文件
（1）复制样板
cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf //使用样板
（2）打开主配文件
vim /etc/dhcpd.conf
（3）编辑主配文件
1 ddns-update-style interim;
2 ignore client-updates;
3 shared-network xxx { //单网卡多网段需要加上这个
4 subnet 10.10.1.10 netmask 255.255.255.0 { //设置子网的网段和掩码
5
6 # --- default gateway
7 option routers 10.10.1.1; //默认网关
8 option subnet-mask 255.255.255.0; //客户端IP的子网掩码
9 //域名服务器
10 option nis-domain "xxxcollege.net"; //nis服务器域名
11 option domain-name "xxxcollege.net"; //DNS服务器域名
12 option domain-name-servers 10.10.1.10;//DNS服务器IP
13
14 option time-offset -18000; # Eastern Standard Time
15 # option ntp-servers 192.168.1.1;
16 # option netbios-name-servers 192.168.1.1;
17 # --- Selects point-to-point node (default is hybrid). Don't change this unl ess
18 # -- you understand Netbios very well
19 # option netbios-node-type 2;
20
21 range dynamic-bootp 192.168.0.128 192.168.0.254; //DHCP池范围
22 default-lease-time 21600;
23 max-lease-time 43200;
24
25 # we want the nameserver to appear at a fixed address
26 host xxx {
27 next-server marvin.redhat.com; //可以删除这条
28 hardware ethernet 12:34:56:78:AB:CD; //这里要改成被分配的主机的物理地址
29 fixed-address 207.175.42.254; //为该物理地址指定IP
30 }
31 }}
4 测试
service dhcpd restart //重启DHCP
service network restart //重启网卡
windows也要在网络连接中禁用再启用重启，若都与指定IP相同则成功
