Nagios Support Forum

I have tried installing fusion several times, but i keep getting errors.

I want to be able to do a full install on a freshly installed CentOS Basic Server on VMware platform.
I know a complete VM downloaded will work, but that is not the issue.

I need to be able to reproduce an installed system, as a prereq for the use of Nagios in our organization.
I used the manual install instructions 1.7 from Oct.2012 (downloaded from Nagios.com)

Basically the procedure is:

1. Start with freshly installed "clean" server
2. wget http://assets.nagios.com/downloads/nagi ... est.tar.gz
(i changed 2010 to 2012)
3. tar xzf fusion-2010-latest.tar.gz
(again changed 2010 to 2012)
4. ./fullinstall
(In /tmp/nagiosfusion)

The script starts and after a while stops with the an error:
the script that failed was: './D-chkconfigalldaemons'

Examining the script i notice that mysqld service is configured, but there seems to be no sql server installed. (unrecognized service when checking status for mysqld)

What is my reasl error

Should mysql have been installed by the fullinstall script or is the configscript wrong?


Thanks for any reation

Looks like you grabbed an old version of Nagios Fusion. Clear out your tmp directory and try this URL.

http://assets.nagios.com/downloads/nagi ... 1.5.tar.gz

If for some reason it throws errors because of the previous install attempt, run the upgrade script.

I have downloaded the r1.5 version and it seems that "latest" is not really the latest!!!

This morning i repeated the process (complete new install CentOS) with the recommended version.
After installing fusion i was able to login via the webinterface and configure fusion.
Everything looked OK and i was getting hopeful that this was the solution.

However......
After a reboot of the new fusion server when i try to access the webinterface : "DB Connect Error [nagiosfusion]: Database connection failed"

A service status check for httpd and postgresql shows that the services are running.

What is the problem here?

I have downloaded the r1.5 version and it seems that "latest" is not really the latest!!!

I think where things got hung up here is that you downloaded the 2010-latest, instead of the 2012-latest. ...And I just pulled up the doc, and it appears our documentation is out of date for that link! We'll make that update today.

Lets start simple and go from there.
If you still get the same message, post the output from:

Unfortunately restarting the postgresql service doesn't help!

I have attached the requested error_log.

Hoping for a solution....

The log-file dissapeared. (extension not allowed?)

renamed the file to error_log.txt and attached again.

I"m noticing that you've re-enabled selinux, which is a likely cause of the problem. Can you try disabling it and see if that resolves the issue. Here are the notable items in the log.

To disable selinux run:

Also, to avoid log spam to the apache log, you'll want to set your timezone in the /etc/php.ini file.

That did the trick! SELINUX was the cause.

I would like to point out the i did NOT RE-ENABLE selinux!!
When installing CentOS 6.3 in the BASIC server method there is NO option to disable selinux.
I think the option is available in the full-install, which is NOT recommended by Nagios.

So in my opinion the disabling of SELINUX should be mentioned as a prerequisit for installing xi or fusion.

My problem is solved at this point, so thank you very much for that, and i hope to see a complete prerequisite description in the near future.

Silly SELINUX Thanks for letting us know your issue was solved!
