Nagios Support Forum

I have a new install of Nagios Core and it appears to be running, but I cannot access the web interface from my location.

The install is on my dedicated server at a hosting center running:
Red Hat Enterprise Linux Server release 5.7 (Tikanga)
with WHM/Cpanel

Nagios is installed in:
/usr/local/nagios

The Nagios subdomain is nagios.xxx.com or xxx.com/nagios

SELinux is disabled:
[root@server ~]# sestatus
SELinux status: disabled
[root@server ~]# getenforce
Disabled
[root@server ~]#

The Vhost section of my httpd.conf is:
<VirtualHost 1.2.3.4:80>
ServerName nagios.xxx.com
ServerAlias http://www.nagios.xxx.com
DocumentRoot /sites/xxx/public_html/nagios
ServerAdmin [email protected]

ScriptAlias /cgi-bin/ /sites/xxx/public_html/nagios/cgi-bin/

Include "/usr/local/apache/conf/userdata/std/2/xxx/nagios.xxx.com/*.conf"
</VirtualHost>




My /usr/local/apache/conf/userdata/std/2/xxx/nagios.xxx.com/*.conf file is called nagios.conf and its contents are:
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">
Options ExecCGI
AllowOverride AuthConfig
Order allow,deny
#Allow from 10.0.0.0/24
</Directory>

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

<Directory "/usr/local/nagios/share">
Options None
AllowOverride AuthConfig
Order allow,deny
#Allow from 10.0.0.0/24
</Directory>



I find that when I check to see if nagios is running with "service nagios status" it is not running,
When I start it, it does run. Maybe it stops when I restart httpd?


I've spent hours and hours on this and cannot find the problem.

Thanks for any assistance you can provide.

Here the Apache log entries I see:
[Sat Feb 14 20:05:57 2015] [error] [client 68.84.164.49] File does not exist: /sites/xxx/public_html/nagios/nagios
[Sat Feb 14 20:05:57 2015] [error] [client 68.84.164.49] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

Did you follow a guide to install Core? Can you provide a link to it?

What version of Core?

I followed this guide, but while troubleshooting, I strayed away from some of the settings. But I did get them all put back.

Nagios 4.0.8

Thanks.

It looks like you ahve 2 script aliases pointing to 2 different locations for the nagios cgi-bin directory: And: Judging by the error: I would guess apache is using the first definition.

In which location did you install the cgi files to?

In which location did you install the cgi files to?

Nagios is actually in /usr/local/nagios/

cgi files are in:
/usr/local/nagios/sbin

Should the nagios.conf that is read as an include override the httpd.conf file?

No, it is a config fragment. But your httpd.conf should be including files from the conf.d directory it is placed in /etc/httpd/conf.d.

Could you run these commands and post back the output

Code: Select all

grep conf.d /etc/httpd/conf/httpd.conf
grep ServerRoot /etc/httpd/conf/httpd.conf

Your second grep returned nothing.
