2. Verify the status of the Network Manager service
Network Manager is a dynamic network controller and configuration system that is used to keep devices and connections open and active when network devices are available. By default, Centos/rhel 7 is installed with Network manager and is enabled.
Use the following command to verify the status of the Network Manager service:
$ SYSTEMCTL Status Networkmanager.service
Run the following command to check the network interfaces managed by the network manager:
$ nmcli Dev Status
If the output of an interface's nmcli is "fractured," it means that the interface is not managed by the network manager and the network is not in effect.
If the output of an interface's nmcli is "connected," this means that the interface is managed by the network manager. You can easily disable the network manager for a particular interface so that you can configure it yourself with a static IP address.
