I’ve been taming my homelab network. All the VMs I’ve installed to try out software that I eventually deploy at work, the few administrative VMs I need for my own “stuff,” etc., and I was pleasantly surprised. Turns out that most of my stuff is reasonably up to date, a bunch of CentOS 8 VMs, a few recent Rocky 8 instances, a few Ubuntu servers, and one lone CentOS 7 instance. <\/p>\n\n\n\n
So I decided I no longer want to support CentOS 7, and since everything’s on ESXi, it’s easy to attempt the CentOS 7 to 8 update I found here: https:\/\/www.tecmint.com\/upgrade-centos-7-to-centos-8\/<\/p>\n\n\n\n
Everything sailed smoothly until the actual package update step. Obviously it’s a lot of packages, etc., a lot of opportunities for things to go wrong. And a couple wrinkles did expose themselves. One was MariaDB and the other was the FreeIPA client. And since I took a snapshot before starting, I felt pretty free to experiment. <\/p>\n\n\n\n
So fuck it. I backed up the MariaDB database itself just in case, and deleted the package.<\/p>\n\n\n\n
The fuck it, I can recreate the FreeIPA config if need be. Deleted the package.<\/p>\n\n\n\n
Some other minor stuff came up as blockers, the rpmconf package, etc., deleted them too.<\/p>\n\n\n\n
Ran the upgrade, it went all the way through. Then I simply reinstalled the MariaDB server and the FreeIPA client using dnf, and they both picked up their original configurations and just worked.<\/em> I love it when that happens. No there’s no more CentOS 7 on my network. <\/p>\n","protected":false},"excerpt":{"rendered":" I’ve been taming my homelab network.
