  • KernelCare Unknown Kernel

    On Cpanel server with KernelCare installed, i keep getting email

    KernelCare

    This is because the kernel is not yet supported by kernalcare. Since this kernal is provided by CloudLinux, you don’t have to worry. CloudLinux support said they do add support for KernelCare after 3 to 4 days of releasing new kernel.

    To disable this warning, edit file

    vi /etc/sysconfig/kcare/kcare.conf
    

    Add

    IGNORE_UNKNOWN_KERNEL=True
    

    You can find more KernelCare options at

    https://docs.kernelcare.com/config-options/

    You can always check if KernelCare supports your current kernel here:

    KernelCare update kernel using cronjob in /etc/cron.d/kcare-cron

    [root@ok cron.d]# cat kcare-cron 
    31 */4  * * * root /usr/bin/kcarectl -q --auto-update
    [root@ok cron.d]#
