Checkmk post CentOS 8 supported distro?

Hi

As we all know EOL for CentOS 8 is end of 2021.

I am a R.L. 8 user and have checkmk 2 POC running without issue. I am hoping to see R.L. listed as support OS distro. I am sure Alma Linux work just fine also but I didn’t test it personally.

What is checkmk’s position on Rocky Linux/Alma Linux support, the CentOS 8 replacement distros ?

+1 for Rocky Linux! I’m running a large production CEE on it, without any issues.

+1 from my part here too!

Hi @T.J_Yang and the others,

just to let you know: The discussion how to deal with the demise of CentOS is already in full swing internally at the tribe. Product Management and Dev is on it and we’re defining the way forward.

Last information I read in this forum was from Lars that everything which is binary compatible with RedHat is supported.

Need to find that post…

We’re looking at AlmaLinux (as they seem best prepared so far). They even created tools to migrate CentOS 7 to (any, not just Alma) 8. Says a lot about their character.

I’ve already done testing with their conversion tools. Impressed so far.

Yes, I checked out Elevate tool also and have moderate success for doing in-place C7toRL8 upgrade. Unfortunately I can only pick one out of 3 main ones(AL,OL,RL).

Hello to all,

Rocky Linux has a conversion tool, too: migrate2rocky which supposedly works for multiple distributions. In all fairness: They say you must already be on major release 8.x of “insert-other-distro-here” in order to migrate to Rocky Linux.

I’ve tried the tool, twice. The first time was an early release, I pretty much ignored instructions/caveats and of course, failed. The second time was recently, where I did spend some time with its instructions
(there are not many…) and successfully migrated a CentOS 8.x stream VM to Rocky Linux.

Your mileage may vary, but my experience with Rocky Linux so far, was very good.

Thomas

@openmindz, Thanks for the sharing.

@cjcox and I were talking about in-place major version upgrade/conversion like from Centos 7 to either Rocky/Oracle/Alma Linux 8. Elevate was a fork of RH’s leapp(for RHEL only) that fill the missed leapp datasets for centos. Yes, I tried and like migrate2rocky script and Oracle and Alma Linux also have similar scripts also.

I am afraid that scripts will not work in our env because the CentOS installations have no access to repos in the internet.
I also dont want to do migrate to CentOS 8 and then to one of this new distros.

Elevate/Leapp can be configured to retrieve *8 pkgs from your internal repository which in turn a mirror of internet ones.

The Elevate/Leapp approach is from CentOS 7 to RL/OL/AL 8 directly.

Some cases need fresh rebuild of machines and in different cases in-place upgrade is viable option.

I’m running checkmk 2.0.0 on an AlmaLinux 8.5 server. No problems at all.

Migrated from a CentOS 7 box by sshing from the new host to the old:

ssh root@oldhost “omd backup sitename -” | omd restore -

It was surprisingly painless.

If you’re running on CentOS 8 or 8-stream, migration to AlmaLinux is easy - just use almalinux-deploy.sh (my version in GitHub - philrandal/almalinux-deploy: EL to AlmaLinux migration tool. handles CentOS Stream 8 to AlmaLinux 8 conversion).
