我在VirtualBox的虚拟机上configuration了DHCP服务器。 本机有2个networking适配器， enp0s3 – NAT（从我有我的networking连接）和enp0s8 – 内部networking（intnet）。 DHCP服务器正在监听enp0s8接口。
configuration：
/etc/dhcp/dhcpd.conf option domain-name "sth.com"; option domain-name-servers ns1.sth.com, ns2.sth.com; default-lease-time 600; max-lease-time 7200; authoritative; log-facility local7; subnet 10.0.3.0 netmask 255.255.255.0 { range 10.0.3.20 10.0.3.30; option domain-name-servers ns1.internal.sth.com; option domain-name "internal.sth.com"; option routers 10.0.3.9; option broadcast-address 10.0.3.255; default-lease-time 600; max-lease-time 7200; } /etc/sysconfig/dhcpd DHCPDARGS=enp0s8 /etc/sysconfig/network-scripts/ifcfg-enp0s8 TYPE=Ethernet BOOTPRO=static NETWORK=10.0.3.0 DEFROUTE=yes IPV4_FAILURE_FATAL=no NAME=enp0s8 DEVICE=enp0s8 ONBOOT=yes BOOTPROTO=none IPADDR=10.0.3.9 PREFIX=24 IPV6INIT=no
因此，我启动了DHCP服务器：
Active: active (running) since Wed 2016-04-27 15:00:50 EEST; 16min ago Docs: man:dhcpd(8) man:dhcpd.conf(5) Main PID: 863 (dhcpd) Status: "Dispatching packets..."

我安装了另一个将成为DHCP客户端的虚拟机。 在/etc/sysconfig/network-scripts/ifcfg-enp0s8文件中，我写了这样/etc/sysconfig/network-scripts/ifcfg-enp0s8行：
DEVICE=enp0s8 BOOTPRO=dhcp NAME=enp0s8 ONBOOT=yes
之后，我重新启动了客户端机器上的networking： systemctl restart network但是，客户端机器没有从dhcpd.conf指定的范围获取enp0s8接口的IP。
有人可以解释我，我做错了吗？
