Nagios Support Forum

Hi all,

My first topic on this forum.

I am running Nagios 4.0.7 on a FreeBSD 8.4 and apache.
After upgrade apache from 2.2 to 2.4 I have now problem to get the web interface fully up and running again.
Yes I know the apache have change the ACL, but there most be more for nagios4.
Any friendly person how can help with the httpd.conf for apache 2.4?
This what I have right now.

What are the symptoms that you are seeing that make you think it isn't working?

I get two frames.
The right one with The webpage cannot be found and This error (HTTP 404 Not Found) and the left just shoing path to diffrent CGI like below.

Current Status
/tac.cgi" target="">Tactical Overview
/statusmap.cgi?host=all" target="">Map
/status.cgi?hostgroup=all&style=hostdetail" target="">Hosts
/status.cgi?host=all" target="">Services

/status.cgi?hostgroup=all&style=summary" target="">Summary

Can you post the appropriate parts of your Apache log files? /var/log/httpd/error_log and /var/log/http/access_log would be the standard locations.

This was the old 2.2 that was working:
<Directory /usr/local/www/nagios>

Options +Indexes FollowSymLinks +ExecCGI
AllowOverride Indexes AuthConfig FileInfo
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUSerFile /usr/local/etc/nagios/htpasswd.users
Require valid-user

</Directory>

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

</Directory>


ScriptAlias /nagios/cgi-bin/ "/usr/local/www/nagios/cgi-bin/"
Alias /nagios /usr/local/www/nagios/

<Directory "ScriptAlias /nagios/cgi-bin">
Options +ExecCGI
AddHandler cgi-script .cgi
</Directory>

This is one of many 2.4 that I have tried with.

<Directory /usr/local/www/nagios>
Require all denied
Allow from 127.0.0.1
DirectoryIndex index.php
AddType application/x-httpd-php .php.
AddType application/x-httpd-php-source .phps.
Options Indexes Includes FollowSymLinks
AuthName "Nagios Access"
AuthType Basic
AuthUSerFile /usr/local/etc/nagios/htpasswd.users
Require valid-user
php_flag engine on
php_admin_value open_basedir /usr/local/www/nagios/:/var/spool/nagios/
</Directory>

<Directory /usr/local/www/nagios/cgi-bin>
Options +ExecCGI
</Directory>

ScriptAlias /nagios/cgi-bin/ "/usr/local/www/nagios/cgi-bin/"
Alias /nagios /usr/local/www/nagios/

Here is the log files:
httpd-access:

10.129.205.129 - nagiosadmin [04/Aug/2014:08:19:50 +0200] "GET /nagios/ HTTP/1.1" 200 1708

Nothing in the httpd-error when I try to access Nagios.
But if I restart apache I get this:

I see this and I cringe:

GET /nagios/stylesheets/common.css?<?php%20echo%20$this_version;%20?>

It looks like something is not parsing PHP properly. Do you have PHP and mod_php installed on your system? Is it being loaded into Apache?

Yes I have both.
I also have cacti installed on the same pc and Cati is using PHP without any problem.

The httpd-error.log is celan now after "apachectl restart" but still I have problem with Nagios4.

What did you do to fix the errors:

Code: Select all

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20100525/gd.so' - Shared object "libfreetype.so.9" not found, required by "gd.so" in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20100525/snmp.so' - Shared object "libpkg.so.1" not found, required by "snmp.so" in Unknown on line 0
PHP Warning: Module 'xml' already loaded in Unknown on line 0

Are you having the same problems with Nagios as before?

Reinstalled the PHP and the moudules.
Do anybody have a httpd.conf example that is working in apache 2.4 that I can try?

//Jan

I don't think we have one internally, though at this point in apache's version cycle we really should. Anybody out there have a working apache 2.4 vhost config?
