①重启/启动网卡失败

service network start

②使用systemctl status network.service命令查看错误详情。

systemctl status network.service

③出现这种报错一般是和 NetworkManager 服务冲突导致的，直接关闭 NetworkManger 服务就好了， service NetworkManager stop

service NetworkManager stop

④禁止开机启动 systemctl disable NetworkManager

systemctl disable NetworkManager

⑤再次重启网卡,启动成功

service network restart
