centos7无法上网

cd /etc/sysconfig/network-scripts

进入到这个目录，并通过ls命令，查看到了

vi ifcfg-ens33

 

 根据这些自己的信息去配置网关文件

重启网关

service network restart

结果出现了这个问题：

Restarting network (via systemctl):  Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.

 解决方法：

systemctl stop NetworkManager

systemctl disable NetworkManager

systemctl start network.service

最后成功ping通
