Nagios Support Forum

So I just ran the upgrade against my Nagios Log Server v1.3 following the upgrade instructions herehttps://assets.nagios.com/downloads/nag ... Server.pdf.

However after starting up the server all I get when I try to go to https://nagiosls.mydomain.local/nagioslogserver is a 404 error stating "The requested URL /nagioslogserver/login was not found on this server."

Any ideas? This is kinda a production down thing, but still within my maintenance window.

Check on the apache configs and ensure that they were update appropriately:
If you have SSL enabled, follow this document (especially the redirect steps at the bottom).

Let me know if you're still having problems after the above. Thanks!

They are indeed the same.

353abd821b0f3310090ab0946f554e87 /etc/httpd/conf.d/nagioslogserver.conf

However my ssl.conf file was totally changed.

Putting the redirect back in place for the default VirtualHost and putting a link back to my cert and key worked to get it back up.

Any idea why ssl.conf got wiped?

This is what was received via stdout when upgrading.

Nagios Log Server Upgrade Complete!

You can access the Nagios Log Server web interface by visiting:

I've walked through all the upgrade scripts I could find. There wasn't anything I saw that would modify the ssl.conf file. The file is owned by the mod_ssl package and that wasn't updated either, just openssl and other related packages.

I also have no idea what may have caused this, the openssl update seems suspicious only because it has 'ssl' in the name - nothing should be touching the ssl.conf file.

I can confirm that this behavior is not present in my lab machine - I tested a 1.3 -> 1.4 upgrade with no issues.

Any luck chasing this down? If you have custom cronjobs/scripts running on the box, could you verify that they wouldn't randomly delete the ssl.conf file?

Not so far. Closest I have is possibly certmonger, but that's just a guess at best. All our machines are tied to a FreeIPA domain controller. That also runs a certificate manager which is managed on the local clients by certmonger. This updates configurations and installs new certificates for services on domain systems. I don't have a running audit trail of that file so not much to go on here.

mod_ssl is the package that provides the /etc/httpd/conf.d/ssl.conf file, did your upgrade log show httpd being upgraded? If so, mod_ssl would be updated as well which may replace that, was there any ssl.conf.rpmsave or anything else in there?

Last install date for those two packages:
httpd-2.2.15-45.el6.centos.x86_64 Thu 06 Aug 2015 04:51:42 PM EDT
mod_ssl-2.2.15-45.el6.centos.x86_64 Thu 06 Aug 2015 04:51:42 PM EDT

Doesn't look like it was modified by a RPM package, so no rpmsave/rpmnew.


Honestly guys, don't spend too much time looking into this. I've got an old snapshot but I'd lose too much data to rollback. It's working, I've notated it for next time I upgrade. I went through your upgrade scripts and I couldn't find anything that would have changed that file. So I'm seriously at a loss, either I had done my redirect differently last time and I didn't notate it, or something changed it. But I've been accessing it via HTTPS since the beginning, so it was working.

I'll keep an eye out for similar cases moving forward - through all of our testing we've yet to see this happen - thanks for the information. May I close this case?
