Nagios Support Forum

Following the Ubuntu quickstart guide for Nagios4 I have installed Nagios 4.06 on Ubuntu 14.04 and it is running (the nagios service). I can get to the default Nagios web page, however when I click on a link the browser downloads the file instead of executing the script. I have populated the following into the apache2.conf file and made sure the paths aligned. I have read many posts, and Apache2 CGI tutorial, however I still cannot figure it out. Any help is appreciated. Thanks

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

<Directory "/usr/local/nagios/sbin">
# SSLRequireSSL
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>

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

<Directory "/usr/local/nagios/share">
# SSLRequireSSL
Options
AllowOverride None
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1

Require valid-user
</Directory>

Are the cgis executable? Is the cgi module loaded with apache:

All of the cgi's in the sbin folder are executable.

I do not have an httpd command. I am not familiar with the cgi module, though looked it up for ubuntu and found this site. http://packages.ubuntu.com/lucid/libcgi-pm-perl
I did an apt-get install for libcgi-pm-perl and it did install 2 new files. I restarted Apache2 though the issue remains. Thanks for the help.

Humor me, and for fun, change this line: to:

Try:

I had previously removed the quotes for the ScriptAlias and tried it again, and it did not have any impact. Reading through the config file I see the other listings did not have quotes so I am permanently removing the quotes.

I ran "apache2 -M | grep cgi" and got the following:

root@logstash141:/etc/apache2# apache2 -M | grep cgi

AH00526: Syntax error on line 74 of /etc/apache2/apache2.conf:
Invalid Mutex directory in argument file:${APACHE_LOCK_DIR}

looking into that error on line 74 in the config file I see where it was suggested in the file to go to the following link for more about Mutex:
http://httpd.apache.org/docs/2.4/mod/core.html#mutex
I can't say the mutex makes much sense to me so I have kept it as is at the default.

Let us know if eloyd's suggestion works for you

The removal of the quotes for the script alias did not have an impact. As I looked at that part of the Apache2 config file it looks like the quotes should not be included so I am permanently removing them.

Please note that there are slashes at the end of the directory names. It's not just about removing the quotes. Please try my suggestion exactly as written.
