Hello there!
First of all, thank you for the nice step-by-step the installation of an Icinga setup :slight_smile:

I was wondering whether you have any questions surrounding it, or if not, then I would move this topic to the how-to category - and merge your other topics on the master setup and module installation into this one.

Cheers,
Feu

thank you very much , i no problem

Hello again @jqrun :slight_smile:
I merged the topics together earlier today.

I would like to ask why you wrote that guide :slight_smile:
Did you feel like anything was missing in the official Installation Documentation?
Did you need any help at some point?

I also noticed, that you installed an EOL version of PHP in your guide, was there any reason for this? As it is not exactly best practice :slight_smile:

:grinning:icinga2 use nice, help more use

I found this guide incredibly useful and this is how the documentation should be in my opinion. Let me explain.

I’m not new to the world of installing software under Linux and the documentation for Icinga is extensive and therein lays the problem. I’ve used Nagios before and built the configs by hand.

I went to the installation section and every distro is listed in the instructions, my first attempt failed as I must have missed a step as I scrolled through sections that were of no interest for the Distro I was using, I completely failed to get a working system. If I hadn’t had found this guide I would have given up at that point, with a the aid of this guide I got a working system. It was still a little difficult as I was using a different version of Ubuntu - The PHP instructions for example didn’t work on my version.

My system works but can only monitor itself, external agents are similarly difficult to follow on how to install, I shall however persevere - no errors in the agent but nothing in the dashboard :frowning:

For me it would have been simpler if the installation was sectioned into the different Distros and if there was a preferred Distro for Icinga - There may be, I couldn’t find it amongst all the docs.

Thank you for your feedback!

We are currently working on a “getting started” section, that aims to simplify the installation process, also focusing on a single OS with a MySQL database and generally limiting the “branches” of having a thousand things to choose from.

I’m glad this guide helped you achieve your goal and I hope we’ll be able to provide a good starting point ourselves as well in the future :slight_smile:
