‍Are you looking to disable NetworkManager in Rocky Linux 8? If so, you’ve come to the right place. In this article, we will guide you through the steps to disable NetworkManager and provide legacy support to the network service. By following these steps, you can ensure efficient and reliable network connectivity on your Rocky Linux 8 system. So let’s get started!

Installing network-scripts package

To disable NetworkManager on Rocky Linux 8, we need to install the network-scripts package, which provides legacy support to the network service. Open your terminal and run the following command to install the package:

yum install network-scripts

Enabling the network service on boot

Once the network-scripts package is installed, we can enable the network service to start on boot. Run the following command:

systemctl enable network

Modifying the interface config file

Next, we need to modify the interface config file to disable NetworkManager for a specific interface. Open the interface config file using your preferred text editor. For example, if the interface name is ens3, run the following command:

nano /etc/sysconfig/network-scripts/ifcfg-ens3

Within the file, add the following line to the last line:

NM_CONTROLLED="no"

Save the file and exit the text editor.

Stopping and disabling NetworkManager service

After modifying the interface config file, we need to stop and disable the NetworkManager service. Run the following commands:

systemctl stop NetworkManager
systemctl disable NetworkManager

Restarting the network service

With NetworkManager disabled, we can now restart the network service to apply the changes. Run the following command:

service network restart

Upon successful restart, you should see the following output:

[root@server ~]# service network restart
Restarting network (via systemctl): [ OK ]

Enabling the network service on boot (again)

To ensure that the network service starts automatically on boot, run the following command:

systemctl enable network

You should receive the following output:

[root@server ~]# systemctl enable network
network.service is not a native service, redirecting to systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable network

Testing the network connectivity

At this point, you can reboot your Rocky Linux 8 system to test if the network comes alive automatically via the network service on boot. If the network connectivity is established successfully, you have successfully disabled NetworkManager and enabled the network service.

Conclusion

In this article, we have provided a step-by-step guide on how to disable NetworkManager in Rocky Linux 8. By installing the network-scripts package, modifying the interface config file, and stopping/disabling the NetworkManager service, you can ensure a reliable and efficient network connection on your Rocky Linux 8 system.
