What should I do if centos cannot start the network card?

Problem:

Use the command systemctl status network to view the error: Failed to start LSB: Bring up/down networking.

Solution:

The NetworkManager management suite that comes with the system affects the startup of the network card, which can be solved by turning it off.

The command is as follows:

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
