Nagios Support Forum

I think the installation scripts are faulty. Should have worked without doing this manual work.
Someone maybe should write a tr?

I got it working.

I made a copy of /etc/httpd/conf.d/nagios.conf/httpd.conf to /etc/apache2/sites-available
Then I renamed the httpd.conf (in sites-available) to nagios.conf
Then the apach2 must be reloded: service apache2 reload

I have same problems with no nagios or nagios.conf file in /etc/apache2/sites-avalable
I used the instructions on Installing_Nagios_Core_From_Source, but got same error message when I used the command sudo a2ensite nagios.
