解决centos7 ping: www.baidu.com: Name or service not known

1、网络配置查看

记住这三个地址

2、编辑Linux中的网络配置文件

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

内容替换如下：

3、重启网络服务

service network restart

centos7好像要这个命令:systemctl restart network

4、DNS文件配置

vi /etc/resolv.conf

5、测试

centos7重启网络服务命令出错

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.

[FAILED]

错误解决可以尝试下把NetworkManager关闭了 然后在输入重启命令重启网络服务

systemctl stop NetworkManager
