Try changing the /etc/httpd/conf.d/nagios.conf file with the following and see if that works for you.

Code: Select all

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">
   Options ExecCGI
   AllowOverride None
   Order allow,deny
   Allow from all
   AuthName "Nagios Access"
   AuthType Basic
   AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users
   Require valid-user
</Directory>

Alias /nagios "/usr/local/nagios/share"

<Directory "/usr/local/nagios/share">
   Options None
   AllowOverride None
   Order allow,deny
   Allow from all
   AuthName "Nagios Access"
   AuthType Basic
   AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users
   Require valid-user
</Directory>

I still say that this is your problem, not the configuration of your web server.
eloyd wrote:More importantly, I don't see anything in the log that shows you are actually hitting your Web server. Something is blocking or you are using the wrong address or else you would have seen browser based hits in your access log.
If you were hitting the web server at all from a browser, even with an invalid URL, you would still see something show up in the Apache log like this:

Code: Select all

192.168.1.108 - - [13/Jun/2016:13:38:05 -0400] "GET /asdf HTTP/1.1" 404 285 "-" "curl/7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.14.0.0 zlib/1.2.3 libidn/1.18 libssh2/1.4.2"

eloyd:

I understand , and it makes sense. Port 80 does not respond to a simple query like telnet <ip_address> 80 yet netstat -tulnp shows httpd listening on port 80.


tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1708/httpd

Very confusing.

Can you post the [sanitized, if required] output of "iptables -L -v -n" please? It's likely a firewall issue.

Also - to add to what @eloyd said. I'd like to make sure apache is actually running, this will help confirm the firewall issue.

From the Nagios machine, can you run curl -v 127.0.0.1/nagios/ and post the full output?

Different versions of apache act differently as well, what is the output of apachectl -v?
