I just installed it and did all the necessary configuration but when I open it on my browser, I can only view the documentation. The other links I go keep showing me internal server error. I checked the apache error logs and it was telling me that permission was denied when trying to access the cgi files that come with Nagios. Please what could be the problem?

A common reason for this problem is that the correct permissions are not applied. When you compiled nagios, did you run "make install-webconf"? After that you should have reloaded the Apache config. The command for this might vary depending on what Linux distribution you are using. As an example, on Ubuntu it is.. /etc/init.d/apache2 reload Another problem can be that the Nagios daemon is not running. If you enter: ps -ef | grep nagios does this show the daemon running? It is also a good idea to check your nagios config before starting the Nagios daemon. You do this by entering: /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg (you might need to alter those if you installed in a different location). If the verification fails, you will need to fix whatever the problems are in your config before continuing. Which version of Linux are you using, and which instructions did you follow when installing Nagios? Nagios can be installed in lots of different ways so it will help to know which one you were working to. Cheers, Jim </div></div>
