环境centos6.5 ，centos6.6

安装dhcp服务  ：yum install dhcp* -y

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

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;}
}

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

客户端更改static为dhcp就可以自动获取了。。。
