Overview

This document describes how to disable the Network Manager service. The Network Manager service automates the network's settings and disrupts connections to the IP addresses that reside in the ipaliases module.

Warning:

You must disable the Network Manager service and enable the network.service service before you install cPanel & WHM.

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

Warnings:

  • cPanel, Inc. does not support the Network Manager service.
  • Exercise extreme caution when you disable the Network Manager. Your server may lose its network services if you do not disable Network Manager correctly.

Disable the Network Manager service

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

Important:

Perform these steps from the server's console in order to prevent any interruption to network connectivity.

  1. Disable Network Manager with the following commands:

     Disable NetworkManager on CentOS 6, CloudLinux 6, Red Hat Enterprise Linux 6 (RHEL), or Amazon Linux...
    service NetworkManager stop
    chkconfig NetworkManager off
     Disable NetworkManager on CentOS 7, CloudLinux 7, or RHEL 7...
    systemctl stop NetworkManager.service
    systemctl disable NetworkManager.service
  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:

    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:

     Restart the network on CentOS 6, CloudLinux 6, RHEL 6, or Amazon Linux...
    chkconfig network on
    service network start
     Restart the network on CentOS 7, CloudLinux 7, or RHEL 7...
    systemctl enable network.service
    systemctl start network.service
