Nagios Support Forum

Hello -

I have a 64-bit CentOS 6.4 machine that had Nagios Core on it, that I am trying to install XI (2012 R2.3) on manually.

I first uninstalled Nagios Core using rpm uninstallers and even deleting the /etc/nagios directory.

When I run the manual installer from /tmp/nagios, the subcomponent install for ndoutils (and nagiosql) both fail with something like:
(for NDOUtils)

or
(for NagiosQL)

I've gone into mysql and done 'drop database' and 'drop user' for both the nagios and nagiosql databases and matching users; and I still get this error for both.

What can I do to reset the mysql install such that these scripts will install?

Thanks!

Tim

Well idealy you would remove the mysql DB and let it reinstall with Nagios XI. Nagios XI requires a clean base system to install properly, anything else and there can be unforeseen issues. Can you not totally remove the database and let Nagios XI re install it?

Well, that's what I've done; I dropped every database inside mysql. There is nothing in there as far as I can tell. I'm not sure how else to remove the database?

Did you restart mysqld afterwards? Are the database files still on the disk:

Ah - looks like with MySQL, even after dropping things, you have to do a FLUSH TABLES and FLUSH PRIVILEGES to clear all the caches.

Once I did that, I was able to get past this error...on to the next one.

Great. We will close the thread, though feel free to open a new one when your next error stumps you. Cheers.
