錯誤資訊 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.解決方法

和 NetworkManager 服務有衝突，這個好解決，直接關閉 NetworkManger 服務就好了， service NetworkManager stop，並且禁止開機啟動 chkconfig NetworkManager off 。之後重啟就好了。
