    Hi everyone,

    I'm facing an issue I have never faced before, my new server have finally been deployed, I was excited to install cPanel, when the installation started it gave me an error about Network Manager being installed, at first I thought Ok, I'll just follow the instructions here:

    How to disable Network Manager on cPanel

    Done! I was going to start the installation again and.. the error persists! how? I checked everything and everything was fine!! searching around google I found how to uninstall Network Manager (instead of only disabling it):

    yum remove NetworkManager

    I thought.. well now that is uninstalled the error will fade away.. but it didn't, it is still showing up when Network Manager have been not only disabled but uninstalled:

    [root@ home]# service NetworkManager status
    Redirecting to /bin/systemctl status NetworkManager.service
    ● NetworkManager.service
    Loaded: masked (/dev/null; bad)
    Active: inactive (dead)

    Hello,

    After disabling the Network Manager service, did you start the network service? Please let us know the output of the following command:

    # systemctl status network

    Ok, I have fixed that error and now it shows:

    Code:
    ● network.service - LSB: Bring up/down networking

    However, while trying to install cPanel, the issue persists.

    If I type service NetworkManager status, this is what I get

    Code:
    Redirecting to /bin/systemctl status NetworkManager.service
    ● NetworkManager.service
       Loaded: masked (/dev/null; bad)
       Active: inactive (dead)
    Network Manager is uninstalled.. I don't get why I get the error..

    Hello,

    May you see if you can open a ticket to Customer Service instead? I will see if I can get the ticket moved over to the Technical Support department so that we can assist you in installing cPanel. Please provide me with the ticket ID once it has been created.

    Looks like a problem with the new centos 7 minimal iso.

    Resolved with:

    Ad to the file in /etc/sysconfig/network-scripts/ifcfg-XXXXX
    Code:
    NM_CONTROLLED=no
    ONBOOT=yes
    
    Then
    Code:
    chkconfig NetworkManager off
    Then
    Code:
    restart

    I managed to sort it in the end, i disabled it but it was still there on start, so i went through process of uninstalling NetworkManager, masking it and disabling it, then did rm -r on /etc/systemd/system/NetworkManager.service, which seem to have sorted it for me, but not best thing to do, but rebooted and was able to install WHM/cPanel, not had any problems since doing it.

    If it helps anyone, I followed the original instructions, tried everything from this thread, then using "locate NetworkManager.service" found several (mostly broken) links, which I removed. Rebooted and the install worked.

    The order of these directives in the config file seems to be important. Didn't work when i initially had them flipped around.

    /etc/sysconfig/network-scripts/ifcfg-etho

    NM_CONTROLLED="no"
    ONBOOT="yes"
