Nagios Core 4.5.9 - Fresh install on Ubuntu 24.04 service takes approximately 17 minutes to start

[saitohas]

"I followed the step-by-step installation several times and I can't figure out why the service takes so long to start. There are no errors in the Nagios, Apache, or Ubuntu logs. I've tried everything and there's no way to get Nagios to start normally."

Just curious if you have localhost in your /etc/hosts file? Or some DNS failure? Sounds like it's waiting for a name translation.

[saitohas]

Yes, this is not the problem

[ericloyd]

Does restarting it also take so long? Or only startup?

[saitohas]

Same delay

[ericloyd]

What happens when you execute the following as root:

time /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Okay, so I don't think it's Nagios itself that has the problem, it's something system related that it's expecting to do and that's hanging until a timeout finishes and then it continues. I'll see if I can get one of our techs to do this install on a box today and see what it does.

I assume you did a normal 24.04 LTS minimal server install?

[saitohas]

Yes, normal 24.04 LTS install
