CentOS 7默认没有开启网络连接，可以设置相关配置(/etc/sysconfig/network-scripts/ifcfg-ens33)

ONBOOT=yes #启用网络连接
    BOOTPROTO=none
    IPADDR=172.16.105.129
    NETMASK=255.255.255.0
    GATEWAY=172.16.105.2
    DNS1=8.8.8.8
    DNS2=8.8.4.4

重启服务并ping测试

[root@localhost apps]# service network restart
    [root@localhost apps]# ping www.baidu.com
