1.修改文件vim /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
TYPE=Ethernet
UUID=95a8e1f5-44de-4b9c-ba42-d3cb797fbb08
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
HWADDR=08:00:27:A4:05:C8
PEERDNS=yes
PEERROUTES=yes
LAST_CONNECT=1526813693
IPADDR=192.168.2.250
GATEWAY=192.168.2.2
NETMASK=255.255.255.0
DNS=114.114.114.114

2.重启服务
service network restart
3.验证
