Lighttpd send Nagios command-line output instead of web interface

Question

I recently installed Nagios on an EC2 instance running AmazonLinux (which is basically SuSe, to my understanding). I'm using lighttpd and mod_cgi to serve the web interface.

When I navigate to a page, instead of getting the actual content, I get this:

Nagios Core 3.3.1

Website: http://www.nagios.org
Usage: /usr/sbin/nagios [options] 

Options:

  -v, --verify-config          Verify all configuration data
  -s, --test-scheduling        Shows projected/recommended check scheduling and other
                               diagnostic info based on the current configuration files.
  -x, --dont-verify-paths      Don't check for circular object paths - USE WITH CAUTION!
  -p, --precache-objects       Precache object configuration - use with -v or -s options
  -u, --use-precached-objects  Use precached object config file
  -d, --daemon                 Starts Nagios in daemon mode, instead of as a foreground process

Visit the Nagios website at http://www.nagios.org/ for bug fixes, new
releases, online documentation, FAQs, information on subscribing to
the mailing lists, and commercial support options for Nagios.

Which appears to be the help document for the command-line version. Here's the relevant bit of my lighttpd.conf:

alias.url = (
                "/nagios/cgi-bin" => "/usr/sbin/nagios",
                "/nagios" => "/usr/share/nagios/html"
)

$HTTP["url"] =~ "^/nagios/cgi-bin" {
        cgi.assign = ( "" => "" )
}

$HTTP["url"] =~ "^/nagios/cgi-bin" {
        auth.backend = "htpasswd"
        auth.backend.htpasswd.userfile = "/etc/nagios/passwd"
        auth.require = ( "" => (
                "method" => "basic",
                "realm" => "Nagios Access",
                "require" => "user=nagiosadmin"
                )
        )
}

$HTTP["url"] =~ "^/nagios" {
        auth.backend = "htpasswd"
        auth.backend.htpasswd.userfile = "/etc/nagios/passwd"
        auth.require = ( "" => (
                "method" => "basic",
                "realm" => "Nagios Access",
                "require" => "user=nagiosadmin"
                )
        )
}

What am I doing wrong?

Answer 1

I figured it out. To people who find this on Google or whatever:

For some reason, the cgi-bin directory is actually installed in /usr/lib64/nagios/. I was pointing lighttpd at the actual executable for Nagios, which was why it was spitting out its help doc.

This is the section that needs to be changed:

alias.url = (
                "/nagios/cgi-bin" => "/usr/lib64/nagios/cgi-bin",
                "/nagios" => "/usr/share/nagios/html"
)
