Phenomenon:

1. Display the eno16777736 adapter as down state via IP addr

2. The Service status network displays the following logs:

....

November 15:30:10 localhost.localdomain systemd[1]: Network.service:control process exited, code=exited Status=1
November 15:30:10 localhost.localdomain systemd[1]: Failed to start lsb:bring up/down networking.
November 15:30:10 localhost.localdomain systemd[1]: Unit Network.service entered failed state.

3. Manually running the network start network does not succeed

Solve

Browsing through the network, trying to modify the MAC address, try to change the network sharing mode from Nat to bridge, or the bridge to Nat is unsuccessful.

There is an article about disabling the NetworkManager service and then starting to succeed, a try is done.

Service Stop NetworkManager

Service Start Network

#设置不启动

Chkconfig Networkmanager.service off

It suddenly occurred to me that once the GUI was installed and then removed, the NetworkManager service was probably enabled.
