Nagios - Access Forbidden 403

Question

I have seen a few question this regard, but unfortunately that does not solve my problem. Please let me know if you have been able to successfully run Nagios on OpenSuse on a virtual machine.

I have Open Suse installed in two different computers. one via VMware and one via VirtualBox and they run just fine for any other application. No problem on accessing network etc.

But after following the open Suse installation steps as mentioned at: http://nagios.sourceforge.net/docs/nagioscore/4/en/quickstart-opensuse.html

I find the "Access Forbidden! Error 403" messege when I start localhost/nagios (removed the http:// purposefully in the post) on firefox. The installation looks went through fine with no error. I am using OpenSuse 13.1 version, I tried with nagios version 4.0.6 and 4.0.7 along with plugins 2.0.2.

I made sure, apache(apache2), gcc, gcc++, kernel-source (as suggested in nagios forum by a user), php, apache2-mod_php5, make etc are all installed. apache2 service is running and was retasrted after running: make install-webconf

The username and password was rightly keyed in :).

Can you please guide me on what is going wrong on this.

Here is the apache2/error_log:

Answer 1

I had a very similar issue on CentOS 7 but I just installed the php package and it worked

yum install php-5.4

Answer 2

I just ran into this same problem (on a Raspberry Pi 3 w/ Raspian Jessie, using install instructions from http://www.howtovmlinux.com/articles/rasberry-pi/install-nagios-core-latest-version-4-x-x-on-raspberrypi-jessie.html) and I will shame-facedly admit that it was because I skipped a critical step in the installation: I neglected to do "make install"!

It seems unlikely that anyone else would make this same bonehead mistake, but in case they do, here's my solution: run "make install"! :-]

Answer 3

I know this is a really old thread,I face the similar issue today but in case of Centos7,The only thing I do to resolve this issue is adding index.php to DirectoryIndex parameter,not sure how much this is useful in case of OpenSuse

httpd.conf

Changed

 <IfModule dir_module>
  DirectoryIndex index.html
   </IfModule>

To

 <IfModule dir_module>
    DirectoryIndex index.html index.php
  </IfModule>
