[root@localhost zzx]# rpm -qa |grep dhcp
dhcp-libs-4.2.5-27.el7.centos.2.x86_64
dhcp-common-4.2.5-27.el7.centos.2.x86_64

[root@localhost zzx]# yum intstall dhcp

已安装:
  dhcp.x86_64 12:4.2.5-27.el7.centos.2                                         

完毕！

[root@localhost zzx]# rpm -qa |grep dhcp
dhcp-4.2.5-27.el7.centos.2.x86_64
dhcp-libs-4.2.5-27.el7.centos.2.x86_64
dhcp-common-4.2.5-27.el7.centos.2.x86_64

[root@localhost dhcp-4.2.5]# cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp.conf  #拷贝配置文件到etc下

修改文件内容

subnet 192.168.56.0 netmask 255.255.255.0 {
  range 192.168.56.150 192.168.56.180;
  option domain-name-servers 8.8.8.8;
  option routers 192.168.56.1;
}     

 按教程把配置文件考到/etc/下  结果启动时失败   提示 See ‘systemctl status dhcpd.service‘‘               运行systemctl status dhcpd.service‘    提示   Loaded: loaded (/usr/lib/systemd/system/dhcpd.service; disabled)   打开 /usr/lib/systemd/system/dhcpd.service    提示ExecStart=/usr/sbin/dhcpd -f -cf /etc/dhcp/dhcpd.conf -user dhcpd -group dhcpd --no-pid  原来是位置不对   正确位置应该是 /etc/dhcp/dhcpd.conf

接着启动  service dhcpd restart  

ps aux |grep dhcp   看到多了一项 dhcpd     7521  0.0  1.8 109256 18220 ?        Ss   10:45   0:00 /usr/sbin/dhcpd -f -cf /etc/dhcp/dhcpd.conf -user dhcpd -group dhcpd --no-pid

说明启动成功
