[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s31f6
NM_CONTROLLED=yes

PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static

IPV4_FAILURE_FATAL=no

IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy

NETMASK=255.255.255.0
GATEWAY=192.168.0.1

DNS2=x.x.x.x

2、 重启服务：

[root@localhost ~]# service network restart

[root@localhost ~]# ping www.baidu.com
