RHEL7: How to install the most recent stable kernel.

Presentation

As it is pretty complicated to compile a new kernel, the ELRepo project provides an easy way to install a recent kernel, if you want to. Its elrepo-kernel channel actually allows you to install the most recent stable kernel.

Installation Procedure

Start by installing the ELRepo repository.

Then, temporary enable the elrepo-kernel channel and install the most recent stable kernel:

# yum --enablerepo=elrepo-kernel install -y kernel-ml

After rebooting, you will be able to choose the new kernel.
If you don’t want to choose at boot, type:

# grub2-set-default 0
