Category: Linux

Linux is my primary operating system. I used it on the servers, desktops, laptops, netbooks, and even mobile phones since approximately 1997. I’ve tried a number of distributions over the years, and even created a couple myself. I still look around sometimes to see what others are up to. But most of my machines are running some sort of Red Hat – either a quick and easy Fedora Linux, or a stable and secure Red Hat Enterprise Server, or a cheaper CentOS alternative.

And while by now I am very comfortable in the Linux environment (both graphical and command line), I still discover a lot of new and interesting things about it. When I come across something worthy, I usually share it with the rest of the Open Software world, using this category.

Terraform – infrastructure automation and management tool

Terraform – infrastructure automation and management tool.  It complements configuration management tools like Puppet and Chef, as well as infrastructure building tools like CloudFormation.  The beauty of it is that it is tool and cloud agnostic.  You can use it to build and maintain infrastructure across multiple clouds.

Upgrading Fedora 14 to Fedora 20 is always fun!

I’m upgrading my wife’s laptop from Fedora 14 to Fedora 20.  That’s plenty of fun!  I’ve done this before with other machines, but memory isn’t my strongest suit.  First, preupgrade fails complaining that there are no repositories anymore.  That’s to be expected, with even Fedora 18 being passed end of life.  The replacement for preupgrade – fedup – isn’t yet available for the releases that old.  Digging around I found a DVD with Fedora 19, which would work just fine, if only upgrade option hasn’t been removed from the recent Fedora releases.

So the only option that I see, except for a complete fresh install, is to follow the yum upgrade path.  Which is a bumpy ride, but it did get me to the destination before.  So here we go …

$ yum clean all
$ rpm -Uvh http://.../releases/16/.../fedora-release*rpm
$ yum upgrade
$ yum update
$ reboot

That’ll get me to Fedora 16. Try the preupgrade/fedup option to go to Fedora 18. If not there, repeat the above. Then go to Fedora 20. Jumping more than 2 releases at a time is not recommended.

Good luck!
