1、問題

今日Linux環境突然出問題，ping本機IP都不行，重新網絡卡出現以下錯誤：

[ck@localhost ~]$sudosystemctl start network.service
Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.

[ck@localhost ~]$ sudo systemctl status network.service
● network.service

2.本次解決方案

[atguigu@localhost ~]$ sudo systemctl disable NetworkManager
