    Hi,

    Yes, it's always a good idea to keep the kernel updated as the older kernels are now been exploited and use to mass delete/replace the files on the server.

    It isn't that easy to go for it without any experience so you should better look for a System Administrator who can upgrade the kernel for you.

    Generally doing yum updates will update your kernel. A reboot is necessary after that.

    You can always run 'yum check-update' or just do 'yum update'

    Check will tell you what will/can be updated. You could always simply select yum update kernelhere

    Hope that helps

    Then it appears to be as if your up-to-date. If this server runs cPanel it's probably being updated automagically.

    Anything in the exclude portion wouldn't be updated by yum and would be updated manually, perhaps by cPanel or just doing it the old fashioned way.

    As long as you reboot once in awhile the kernel updates would be applied.
