vi /etc/sysconfig/network-scripts/ifcfg-ens33

修改如下配置

TYPE="Ethernet"
BOOTPROTO="dhcp"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
NAME="eth0"
UUID="ae679cf5-f894-4e23-8a82-60a220f69299"
DEVICE="eth0"
ONBOOT="yes"
IPADDR="192.168.8.100"
PREFIX="24"
GATEWAY="192.168.8.1"
DNS1="114.114.114.114"

重启网络

或者
service network restart
