While compiling a kernel nowadays isn’t rocket science anymore, the first way is still preferable and will save you a lot of time because others have been through the second method and present you the result of their work:) Installing a newer kernel in CentOS If you’re using CentOS as your desktop-system, you probably already heard of the EPEL (Extra Packages for Enterprise Linux)-repository which contains extra and newer ready-made packages that are by default not in RHEL, CentOS or derivatives. Next to EPEL, there is the ELRepo-repository which also contains extra packages, ready-made for RHEL, CentOS and derivatives but it focuses mainly on hardware: drivers, firmware, network, file systems, Of course if the focus is on hardware, newer kernel versions can’t be absent here.
