centos系统网卡无法启动怎么解决

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

(推荐教程:centos使用教程)

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
