Question

【wifi网络】在VMware【NAT链接模式】时隔几个月没有动之后，重启网卡出现

Restarting network (via systemctl):  Job for network.service failed. See 'systemctl status network.service' and 'journalctl -xn' for details.

根据以上提示，执行systemctl status network.service查看：

network.service - LSB: Bring up/down networking
   Loaded: loaded (/etc/rc.d/init.d/network)

后百度谷歌折腾3小时分别尝试以下选择无果而终，特来求助

1.检查并更换网卡mac地址

2.关闭禁用网络管理器systemctl stop NetworkManager

3.删除磁盘虚拟机文件，重新安装Centos

在操作以上步骤后，重启网卡还是第一次的错误

最后我清掉，花了一小时重新安装上
