Nagios XI on RHEL / Rocky Linux / Alma Linux 9.0

[itunixops]

Has anybody tried to install XI on RHEL9 yet? I tried it as an experiment and couldn't get past the initial install phase. Would anybody know if this is supported on RHEL9 or is XI 6 going to be run natively on this?

I installed it perfectly on my instance of RHEL 9. Did the quick install if that matters. According to document you need CodeReady Builder to be enabled, maybe that could be why for you?

We did try a test run on RHEL 9.2 and so far so good. We also tried with Alma and rocky and had to make some modifications to those to make it work. Otherwise were not seeing any problems.

Thanks for the input

Hey itunixops, thanks for reaching out. We do currently support Rhel 9 for Xi5 and it sounds like you were able to get a version working for 9.2 which is awesome. Something that may have stopped the initial from working is that PCRE2 needs to be updated or the installation will break. Our installation will run updates unless prompted not to, so that may have been the issue.

We just did this as a test. Were actually waiting to see XI 6 (or whatever it will be called) before we commit to rhel9 support.

On el9 you need the codebuilder repo, yes, that is stated clearly in docs.

Unfortunately, the docs do not make clear the requirement for EPEL, nor do they mention the requirement for http_proxy environment variable to be set.

The installer needs access to cpan online, and also uses curl or wget to download a huge pile of garbage from nagios website also, eg this:

So it is mandatory to have access to arbitrary sites on the internet, either directly if you're at home, or via http_proxy if you're in any sort of corporate environment.
