1. 环境centos6.5 ，centos6.6

  2. 安装dhcp服务  ：yum install dhcp* -y

  3. 编辑配置文件/etc/dhcp/dhcpd.conf我这里直接copy覆盖之前的内容：

  4. ddns-update-style interim;
    ignore client-updates;
    next-server  192.168.77.168;
    filename "pxelinux.0";
    allow booting;
    allow bootp;
    subnet 192.168.77.0 netmask 255.255.255.0 {
    # --- default gateway
    option routers        192.168.77.1;
    option subnet-mask      255.255.255.0;
    #   option nis-domain       "domain.org";
    #  option domain-name "192.168.0.10";
    #   option domain-name-servers  192.168.0.11;
    #   option ntp-servers      192.168.1.1;
    #   option netbios-name-servers  192.168.1.1;
    # --- Selects point-to-point node (default is hybrid). Don't change this unless
    # -- you understand Netbios very well
    #   option netbios-node-type 2;
    range  dynamic-bootp  192.168.77.100 192.168.77.200;
    host ns {
    hardware ethernet  00:1a:a0:2b:38:81;
    fixed-address 192.168.77.101;}
    }

  5. 根据自己情况更改就ok了，，，重启服务/etc/init.d/dhcpd restart 成功

  6. 客户端更改static为dhcp就可以自动获取了。。。
