报错信息如下：

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.

解决思路如下：

使用命令 systemctl status network 查看报错：Failed to start LSB: Bring up/down networking

找到原因并解决：

系统自带的NetworkManager管理套件影响到网卡的启动，关掉就可以了。

命令如下：

systemctl stop NetworkManager		//停止NetworkManager
systemctl disable NetworkManager	//并使其失效，开机不启动
systemctl start network			//启动网络后就OK了
