13.2. Configuring Apache for Nagios

Problem

You can read the Nagios HTML docs in a local web browser or HTML-enabled file browser like Konqueror, but Apache doesn't seem to know they exist. Nagios needs Apache support to be fully functional and to display all the status pages and command pages. How do you make it go?

Solution

You need to use Apache's access controls. First, create an Apache password for the Nagios user:

	# cd /usr/local/nagios/etc/
	# htpasswd -c htpasswd.users nagios
	New password:
	Re-type new password:
	Adding password for user nagios

Then, make the password file owned and readable/writable only by the HTTP user:

	# chown HTTP user htpasswd.users
	# chmod 0600 htpasswd.users

On Fedora, add this directive to your /etc/httpd/conf/httpd.conf file:

	Include /etc/httpd/conf.d

Next, create /etc/httpd/conf.d/nagios. On Debian. create /etc/apache2/conf.d/nagios. Add these directives to the file, using your own subnet on the line Allowfrom192.168.1.:

 ## conf.d/nagios ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin <Directory "/usr/local/nagios/sbin"> Options ExecCGI AllowOverride None Order allow,deny HostnameLookups On Allow from localhost Allow from 127.0.0.1 Allow from 192.168.1.
