cPanel error networkmanager is installed and running

by | May 5, 2021

We come across the cPanel error networkmanager is installed and running while we try to install cPanel on Centos 7.

As part of our Server Management Services, we assist our customers with several cPanel queries.

Today, let us see how to resolve this NetworkManager enabled error.


cPanel and NetworkManager

cPanel alongside Web Host Manager facilitates and makes web hosting easy for website administrators.

However, before we proceed to install them, we need to note a few things. We should ONLY install cPanel and WHM on a freshly installed Operating system.

Once done, we cannot remove the software. Though if we wish to remove it, we must reinstall the OS.

To install cPanel and WHM, we must log in as root or as a user with root privileges.

For commercial hosting, we require a license. To obtain the license we must have a public IP address that is static, not a dynamic or internal IP address.

NetworkManager is a daemon that sits on top of libudev and other Linux kernel interfaces. It provides a high-level interface for the configuration of the network interfaces.

How to solve this error?

Moving ahead, let u see how to resolve this error. In order to do so, our Support Techs suggest the steps below.

First and foremost, we disable the NetworkManager service on CentOS 7 or CloudLinux 7 server. To do so, we use the following commands:

# systemctl stop NetworkManager.service
# systemctl disable NetworkManager.service


[[email protected] home]# systemctl stop NetworkManager.service
[[email protected] home]# systemctl disable NetworkManager.service
Removed symlink /etc/systemd/system/
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.

Then we change the “NM_CONTROLLED=no” parameters in each network configuration file. It is under the/etc/sysconfig/network-scripts directory.

Eventually, we use the commands below to restart the network service on the server:

# systemctl enable network.service
# systemctl restart network.service

Now, we will be able to install the cPanel without any issue on Centos 7 server.
