How To Disable NetworkManager on AlmaLinux 8

Disable NetworkManager on AlmaLinux 8

In this tutorial, we will show you how to install NetworkManager on AlmaLinux 8. For those of you who didn’t know, NetworkManager is the default tool for configuring and managing the network services on AlmaLinux 8 or CentOS 8, there are situations where it may be necessary to permanently disable NetworkManager, and use alternative methods to configure and manage the network. Remember good practice always demands that the NetworkManager service is up and running for automatic detection of networks and managing interface settings.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step turn-off of the NetworkManager on an AlmaLinux 8. You can follow the same instructions for Rocky Linux.


  • A server running one of the following operating systems: AlmaLinux 0r Rocky Linux.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for NetworkManager.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Disable NetworkManager on AlmaLinux 8

Step 1. First, let’s start by ensuring your system is up-to-date.

sudo dnf update
sudo dnf install epel-release
sudo dnf install network-scripts

Step 2. Disable NetworkManager on AlmaLinux 8.

To disable the NetworkManager service in AlmaLinux 8 or CentOS 8, run the following command below:

sudo systemctl stop NetworkManager

Confirm the status of the NetworkManager:

sudo systemctl status NetworkManager

Next, we add NM_Controlled=no to the interface config file:

nano /etc/sysconfig/network-scripts/ifcfg-<interface>

Replace with the interface name from ifconfig -a (or) ipaddr, for example:

nano /etc/sysconfig/network-scripts/ifcfg-ens2

Add the following line:


Restart Network to apply all the configuration changes:

sudo systemctl restart network
sudo systemctl enable network
