wget http://server.domain11.example.com/pub/updates/kernel-package.rpm sudo yum install kernel-package.rpm grub2-mkconfig -o /boot/grub2/grub.cfg grubby --info=ALL (to check which kernel index it is) grubby --set-default-index (change to what index the kernel is) uname -a (to see current kernel) reboot uname -a to check for proof
