"Not running" in WebUI after upgrade from3.5.1 to 4.2.2

Post by alexnorton »

Hello!

Few days ago I upgrade Nagios Core from 3.5.1 to 4.2.2. Old version was installed from repo, new version was installed from sources. I move all configuration files to directories related to new version, corrects all parameters. Nagios service "per se" working correctly.

Service status:

Code: Select all

service nagios status
nagios (pid 29617) is running...


Process list:

For WebUI I use Apache 2.4. But, unfortunately, in WebUI I catch errors.

At main page: http://prntscr.com/d6svvg
At any page: http://prntscr.com/d6swc3

I checked all configs and permissions, but cannot locate an error. Please, help! :roll:

When you say you checked the configs, did you run /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg? Either way, could you post the output of that?

Also, can you give the output of tail -100 /usr/local/nagios/var/nagios.log. If you have your logs in a different location, swap out that locations.



I'm just going to put a note in here to help with file paths for community members that may not be familiar: Amazon Linux is loosely based on CentOS.

Old version was installed from repo, new version was installed from sources.
To add to what @dwhitfield mentioned, this is the part that scares me. What was done exactly for this upgrade, did you cleanly remove the repository version? There is a possibility that they are using different structures / different configuration files based on this. The fastest resolution is more than likely going to be reinstall on a clean machine -> move over config files. The installation instructions can be found here - https://support.nagios.com/kb/article.php?id=96

Hello!

Thanks for your reply!

I have already published results of configuration test, but moderator have deleted it, by some reasons, I think. ;)

As you can see, all works fine... except WebUI :cry:
What was done exactly for this upgrade, did you cleanly remove the repository version?
I do not remove repo version. Now, I make backup of whole machine and remove old version. I afraid it remove some necessary configs.
Amazon Linux is loosely based on CentOS
Did it mean what Amazon Linux uncompatible with Nagios 4? Nagios 3 is in repo and works normal.

Just a guess, but if your first two posts were very similar, the moderator may have thought it was a double-post. People often post a second time because they do not see their first post.

We don't have Amazon-specific install instructions. I just didn't want community members trying to piece together where your files might be. Debian and CentOS/Red Hat/Oracle have some very specific differences for apache. Other distros have differences too. More-or-less, I'm just signaling that we are in Red Hat-land. Nothing to worry about!

I don't want this earlier statement to get lost:
The fastest resolution is more than likely going to be reinstall on a clean machine -> move over config files. The installation instructions can be found here - https://support.nagios.com/kb/article.php?id=96
Please let us know if that is not going to work for you.

Distribution RPM upgrade by source is not a supported upgraded path. Do not mix and match upgrade between source and RPM. Please either create a new cleanly installed server with Nagios Core from source and migrate the configs or stick with distribution RPM's only.

The first method will allow you to stay more current and compliant with Nagios, but it's more manual work. The second method usually lags somewhat behind the current release of Nagios Core and may have other distribution specific requirements.
