In addition to what @dwhitfield posted -

Please run the following and post the output -

Code: Select all

tail -n100 /var/log/httpd/error_log
tail -n100 /var/log/httpd/ssl_error_log
tail -n100 /var/log/httpd/access_log
tail -n100 /var/log/httpd/ssl_access_log

Also, post your entire /etc/httpd/conf.d/ folder for us to look at.

Lastly, we'll need to see which version of apache you're running. Please show us the output of apachectl -v

I've changed my Nagios.conf to replicate yours and I've included all files requested for in the zip file.

Thanks,

You have quite a few problems going on -

Code: Select all

[root@localhost tmp]# [Mon Jan 16 10:42:01.525913 2017] [:error] [pid 22657] [client 127.0.0.1:41323] PHP Warning:  Unknown: open(/var/lib/php/session/sess_n32atlogtstva2onqtsmqifhs1, O_RDWR) failed: No space left on device (28) in Unknown on line 0

You'll need to add more space to the machine.

The contents of your conf.d directory suggest this is not a clean system, there are multiple other processes running on it which can affect Nagios -

Code: Select all

Please install on a minimal machine, with no prior applications running on it - this is how you can get a proper install setup & working. Having all of these items already on the machine is going to affect the initial setup.

This was a clean install. Please assist on how to get through the security error.

[techcrunch]

I can get to the installer page. However when I set up the URL, Admin Name, Password, etc, ----> then click install, I get the Forbidden error. Please assist.

[dwhitfield]

This was a clean install.

Are you just importing all of your Apache configs from another machine? Are you installing clean and then adding on top of it?

Did you take care of the space issue?
