    How to Build & Install Custom Kernel on CentOS GNU/Linux

    Installing Custom Kernel CentOS

    First, check your current Kernel version with:

    uname -r

    A Kernel 4.4+ may be required.
    Else you may try first to Upgrade the current System:
    Again better to Upgrade the System with:

    sudo yum upgrade
    sudo reboot

    And then again:

    sudo yum install kernel-headers kernel-devel

    Authenticate with the User Admin Pass.
    If Got “User is Not in Sudoers file” then see: How to Enable sudo.
