that should do!

make sure that you reboot after the upgrade to load new kernel.

Use

uname -r

to find kernel version

Thank you mate!

When I run cat /etc/yum.conf I notice this:
distroverpkg=redhat-release

Is not better to have distroverpkg=centos-release?
Or doesn't matter?

Thank you once again

CentOS is a RedHat based OS so these settings are correct.

If you do a "yum update -y" it will simply update all packages including kernel.

Make a reboot to load new kernel.
