RHEL

[root@rhel-tiger-14-6 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux release 8.4 (Ootpa)
[root@rhel-tiger-14-6 ~]# uname -r
4.18.0-305.25.1.el8_4.x86_64
  • Consult the installation instructions that Red Hat provides.
  • For a fresh installation, selecting Minimal Install for Software Selection is recommended, as you will add additional packages as needed.

  • You should register RHEL and consider restricting the update process before performing an update:

    [root@rhel-tiger-14-6 ~]# subscription-manager register Registering to: subscription.rhsm.redhat.com:443/subscription Username: xxxxxx Password: xxxxxx The system has been registered with ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx The registered system name is: rhel-tiger-14-6
    [root@rhel-tiger-14-6 ~]# subscription-manager release --set=8.4 Release set to: 8.4
    [root@rhel-tiger-14-6 ~]# yum -y update <output omitted for brevity>
    [root@rhel-tiger-14-6 ~]# reboot

    Note

    This document continues to describe the installation of specific drivers for the NICs used in the system. This is effectively a kernel module, which must be compiled against the running kernel. While this is not a problem if you can compile the module every time that the kernel is updated, the Intel-provided driver did not compile against the newer kernel in RHEL 8.5.

    This is likely due to RHEL 8.5 being new at time of writing. Intel may update their package accordingly. However, it illustrates the importance of exercising due care around updating the system, as changing the driver version could impact both functionality and performance.
