Nagios Support Forum

Hello,

I've finally installed Nagios XI for evaluation on Cent OS and I'm able to access the webgui, etc...

I added a host using the wizard as well as installed NSClient++-0.3.9-Win32.msi on the target machine (W2K - not server), applied configuration, but the host I just added is not showing in the host details...

also, System Problem (dashlet?) is indicating "backend database is not running" and "active host/service/notification" checks are disabled

Please advise

Did you use the steps outlined in these documents?

Go to: Core Config Manager->Tools->Write Config Files and click on the four "Go" buttons. Check for errors in the output.

I followed the instructions, but unfortunately, although Nagios XI install succesfully, there are still some issues with it since some of the required files specifically nrpe was copied from a different box. I have not been able to do a full install of Nagios XI in my box.

right now when testing agent from the server I get this error:

[root@DEV-NAGIOSXI libexec]# ./check_nrpe -H 10.18.4.113
./check_nrpe: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory

Do you have the ssl libs installed?

yum install openssl openssl-devel cyrus-sasl cyrus-sasl-devel libgsasl libgsasl-devel

installed it and I"m still getting the same error
[root@DEV-NAGIOSXI libexec]# ./check_nrpe -H 10.18.4.113
./check_nrpe: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory

I've noticed that although the installation guide refers to a clean install, and pre-reqs are basically CentOS or RedHat, what are the other software requirements needed to be able to successfully install? (mysql, openssl, psql, etc......) Also, does the fullinstall installs nrpe and check_nrpe? It always seems to bomb when it gets to that point...

Go to the nagiosxi folder in /tmp (if you put it there) and run: Note: you will have to delete any files named: "installed.***" in the "nagiosxi" folder prior to running the "./upgrade".
See if this is going to fix your problem.

thanks for your response. I ended starting form scratch
1. Installed CentOS 6, base server and included MySQL, PHP and Psql
2. after CentOS, installed gnome, gcc and mrtg
3. downloaded Nagios XI latest release 1.8
4. extracted
5. ran ./fullinstall
6. VIOLA!!! successful install!!!

Good deal, glad it's working for you!
