NagiosXI on AWS.

[derik.petty]

Is there an updated doc for deploying either a pre-built ami or something for nagiosxi in amazon aws. The last document I can find for it was dated from 2016 and the ami does not have nagios running in it after build.

Hi Derik,

Are you following the document below? It was last updated in January of 2019 and should work. Let me know. Thanks.

How To Create A Nagios XI Instance In The Amazon EC2 Cloud

[derik.petty]

Yeah that was the one I was using. the AMI image ID goes back to the same one as the 2016 article. But after launch there not an install of nagios or nagiosxi to be found. There is also no repo files for nagios. But more importantly there is nothing listening on port 80 or 443 to do the setup like the document directs after launching on aws.

So, I am thinking maybe I followed the document wrong or something. When you put in the AMI image number it comes back with multiple entries. I chose the one for nagiosxi on centos 7. Maybe I needed to pick another one or something. Please advise.

Thanks.

Hi Derik,

Just to confirm, that instance status is running, it can take some time to be fully functional. Can you check the system log in the EC2 console for any messages and post them to the thread?

So, here is the searching for and results of anything Nagios on the launched AMI. The server has been running now for over 5+ hours. So, don't think it is a still initializing thing. Also I have already updated the system and added to freeipa. So, the system is running. Btu there are no traces of Nagios to be found anywhere. Also nothing in the repo folder for nagios. I added epel myself.

Ok. maybe I found the problem. It looks like it tries to install after the system is running instead of being in the image. Let me try to get an outside dns server and proxy set up to see if that fixes the problem.

Apr 29 17:20:29 nagios-0001 rc.local: 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0curl: (6) Could not resolve host: assets.nagios.com; Unknown error

So, it looks like it may be trying to reach out at boot up.

Hi Derik,

Let me try to get an outside dns server and proxy set up to see if that fixes the problem.

Sounds good. Yeah, once the operating system comes up it will try to grab the latest version and install it.

[derik.petty]

ok. So, I guess this is something that only happens during the first boot process. So, I have it configured for outside resolving dns servers and configured to use a proxy server out. During boot I do not see it reaching out to the internet or using the proxy at all. I have verified it can get to and resolve assets.nagios.com doing a curl. So, I guess at this point I will just have to install it myself. Is what it is. Thanks for the help.
