Nagios Support Forum

I have followed the instructions in the offline install pdf document and nothing seems to be working.
The rpms installed, I got the "completed" message.
Apache was not running, I started it up and went to <myserver>/nagiosxi and got a "404 not found".
Went to <myserver>/nagios and I get a dialog asking for an id and password. I have tried every id and password I can find and none work.
I did a service nagios status and it came back as not running. So I did a service nagios start and got many errors about missing config files.
Checked the install.log file and it just lists all the rpm's that were installed, no other messages.
What do I do???

Hello, @duane909. Do you remember seeing any errors on the screen while nagios was installing RPMs? If you haven't looked at the installation I suggest removing all nagios and nagiosxi rpms from the server and rerunning the full install script one more time. While it is running look at the output in the command line and if you see any errors share them with us in this thread.

Hi,
I did not see any errors during the rpm install, was hoping I missed something and looked in the install.log but no errors there either.
I did remove all the naigios and nagiosxi rpm's (and all the config files I created), reinstalled the rpm's and got the same result.
No errors on the command line, no errors in the install.log file.
Would I see more install steps if I could log on to the web interface?

@duane909, No, I don't think you'd see any more errors in the GUI. Please sign in to the console as the nagios user, run the reconfigure script and show me the output:

su - nagios
/usr/local/nagiosxi/scripts/reconfigure_nagios.sh

Please send me the list of the installed rpm packages. Run the command and upload the nagios.txt file from the /tmp/ folder:

rpm -qa > /tmp/nagios.txt

Run this command and show me the output:

ls -l /usr/local/nagios/etc/

Upload the /etc/sudoers file.

cat /etc/httpd/conf.d/nagios.conf

cat /etc/httpd/conf.d/nagiosxi.conf

grep nag /etc/passwd
grep nag /etc/group

Results for the questions are in the attached file.

Do you have this file?
Please attach that if you do so that we can see what occurred.

Ok, found part of the problem.
Our active directory server already had the "nagios" accounts but the local server did not. When the install creates those accounts and groups they have the wrong ID numbers causing permissions problems. I manually created local accounts that mirror the ones in active directory.

The install will now get far enough that I get the Nagios XI web interface (and finished the install), but the monitoring engine will not start.

The current error message and install.log is attached.

Please try running these commands from the installation directory and see if it resolves your issue::

Have a new error, see attached file.

Nevermind, same problem as above. This time it was the apache user and group that needed to be created locally using the same id numbers as up in the active directory.
