What is the code to update the Kernel from the root command line?
Using YUM is the easiest way to update your Kernel to the latest version within its major release. For example, CentOS 7 can only be upgraded to the highest 7 version. To upgrade from CentOS 7 to AlmaLinux is a much more difficult and risky process.
Simply log into your server with root via SSH and run this code:
yum -y update kernel
