Overview

This document describes how to disable the Network Manager service on supported operating systems. The Network Manager service automates the system’s network settings and disrupts connections to the IP addresses that reside in the ipaliases module.

When you disable the Network Manager service, you disable this automation. You must manually address any changes to the system’s network settings. For example, if you disable the Network Manager, then reboot the system, the system will not automatically reconnect any preexisting connections.

When should I disable Network Manager?

You must disable the Network Manager service and enable the network.service service before you install cPanel & WHM on CloudLinux™ 7 systems.

Disable the Network Manager service

To disable the Network Manager service, perform the following steps:

1. Disable Network Manager with the following commands:

   1 2	systemctl stop NetworkManager systemctl disable NetworkManager

2. Change to the /etc/sysconfig/network-scripts directory.
3. Open the ifcfg-eth0 and ifcfg-lo files with your preferred text editor and, if they exist, set the following keys’ values:

   1 2	NM_CONTROLLED=no ONBOOT=yes

   Important:

   If either of these keys does not exist in your ifcfg-eth0 and ifcfg-lo files, do not add it. Instead, proceed to Step 4.
4. Run the following commands to restart the network:

   1 2	systemctl enable network.service systemctl start network.service

For more information about how to disable the Network Manager service, read RedHat’s Disabling Network Manager documentation.

When will cPanel & WHM disable the Network Manager?

On systems that run the AlmaLinux OS 8 or Rocky Linux™ 8 operating systems, the cPanel & WHM installer will automatically disable the Network Manager service and enable the network.service service.
