Upgrading RHEL 8 to RHEL 8.1

Red Hat Enterprise Linux 8

Needed to reboot my Red Hat Enterprise Linux 8 desktop anyway, so decided to upgrade it to RHEL 8.1.

Check That Your Software Subscription is Active

For example, I realised that I have still been using the RHEL 8 beta subscription instead of the Developers License. After completing Red Hat subscription registration, I got the following:

greys@redhat:~ $ sudo subscription-manager list
 +-------------------------------------------+
     Installed Product Status
 +-------------------------------------------+
 Product Name:   Red Hat Enterprise Linux for x86_64
 Product ID:     479
 Version:        8.1
 Arch:           x86_64
 Status:         Subscribed
 Status Details:
 Starts:         14/11/19
 Ends:           13/11/20

Upgrade Red Hat OS with yum-update

yum tools are more integrated that many people though! So I’m still using yum update instead of dnf:

root@redhat:~ # yum update

 Is this ok [y/N]:

And that’s it! I rebooted the server and my OS is RHEL 8.1 now:

Web Console in RHEL8

I’m not a fan of web interfaces for managing Linux systems and usually don’t see them unless a hosting provider preinstalled something. But it seems my default Red Hat Enterprise Linux 8 in a VirtualBox VM got the web console enabled by default.

Accessing Web Console in RHEL8

I see reminder of the web console upon every SSH login into the VM:

Web console: https://rhel8:9090/ or https://192.168.X.Y:9090/

So, connection to the virtual machine’s IP address on port 9090 will open the RHEL8 web console:

Screenshots of Web Console in RHEL8

Here are just the screenshots of the web panel, it seems most of the common tasks can now be accomplished using the panel – from joining AD domain to managing users, updates, disk storage and subscriptions. Pretty cool!

What do you like most in Red Hat Enterprise Linux 8? Let me know!
