Yes even with those changes this is what happens

The error is clear, you have a duplicate entry somewhere. Please run cat /etc/httpd/conf.d/* | grep 'nagiosgraph' and post the result.

Additionally, I don't see Require all granted - this is needed on Apache 2.4+ - this could also be why you're seeing Forbidden.

Hi Rob,

Here you go;

nagios@nagios:~$ sudo cat /etc/httpd/conf.d/* | grep 'nagiosgraph'
cat: /etc/httpd/conf.d/*: No such file or directory

I did have the allow all unhashed but i hashed it based off earlier posts

It isn't the allow all, but rather the exact words 'require all granted' that matter. That's the only thing that needs to be uncommented, not the rest of the stuff.

What OS are you running? If it's Debian / Ubuntu try -

Code: Select all

cat /etc/apache2/conf.d/* | grep 'nagiosgraph'

i added the Require all granted to conf file and restarted apache2 same error

ngshared.pm - shared subroutines for the nagiosgraph programs
ngshared.pm uses B<nagiosgraph.conf> for most configuration.  ngshared.pm also includes subroutines to read from B<hostdb.conf>, B<servdb.conf>, B<groupdb.conf>, and B<rrdopts.conf> files.  These files are typically located in /etc/nagiosgraph.
Copy this file into a configuration directory (/etc/nagiosgraph, for example) and modify the B<use lib> line in each *.cgi file to the directory.
Alan Brenner - [email protected]; I've updated this from the version at http://nagiosgraph.wiki.sourceforge.net/ by moving some subroutines into this shared file (ngshared.pm) for use by insert.pl and the show*.cgi files.

Where is your apache installed? You'll want to run that command against the folder that contains your apache configuration.

Additionally, the command you ran worries me as it's finding the apache configuration in your nagiosgraph install directory. Do you have this file referenced to include from apache?

nathanplatt · Post by **nathanplatt** » Wed Mar 30, 2016 12:38 am

I think perhaps this is where i've gone wrong,

Apache2 is installed in /etc/apache2/
The Nagiosgraphs is installed in /usr/local/nagiosgraphs/share/

when running thru the setup instructions I wasn't sure of this and followed the defaults. Here is a tree of the folders to help:

Okay so i found the apache2 error but i may have just put us back to square one. I found that due to the multiple attempts to fix this on my own, i had a nagiosgraph.conf in the sites-enabled folder, so this is where the duplicate was being created from. Deleted this and now apache2 restarts fine.

I'm guessing from your previous comment that the share folder is probably in the wrong location.

Let me know.

Are you still seeing a forbidden error? Please post the nagiosgraph.conf file from your sites-enabled folder.

nathanplatt · Post by **nathanplatt** » Wed Mar 30, 2016 11:08 am

I am still seeing the error, i deleted the one from the site-enabled folder to stop the error happening. Currently that folder only has the default site and nagios in it.
