Munin Dynamic Graph Zoom (Dynazoom) Not Working (Centos6,Nginx,PHP-Fpm)

Munin dynamic graph zoom (dynazoom) not working (CentOS6,nginx,php-fpm)

You've mapped location /cgi-bin/munin-cgi-graph/ via FastCGI passthrough to PHP-FPM, but that works for PHP scripts, not for arbitrary CGI scripts such as Munin's CGI grapher, which is actually Perl. To make that CGI script speak the FastCGI protocol, the wrapper you need to use would be the generic spawn-fcgi.

Munin zoom isn't working

I know this is over a year old but I'm sure there are other people having this issue and finding this on google. (like me)

This is for Debian 7.6 + Munin version 2.0.6-4+deb7u2. Zoom is actually working but it's localhost only. I didn't test this on Freebsd or any other bsd/linux distros so far but I think the problem&solution will be similar.

Please edit this file:

/etc/munin/apache2.conf

# Enables fastcgi for munin-cgi-graph if present
ScriptAlias /munin-cgi/munin-cgi-graph /usr/lib/munin/cgi/munin-cgi-graph
<Location /munin-cgi/munin-cgi-graph>
        Order allow,deny
#       Allow from localhost 127.0.0.0/8 ::1
        Allow from all
        # AuthUserFile /etc/munin/munin-htpasswd
        # AuthName "Munin"
        # AuthType Basic
        # require valid-user
        <IfModule mod_fastcgi.c>
                SetHandler fastcgi-script
        </IfModule>
</Location>

ScriptAlias /munin-cgi/munin-cgi-html /usr/lib/munin/cgi/munin-cgi-html
<Location /munin-cgi/munin-cgi-html>
        Order allow,deny
#       Allow from localhost 127.0.0.0/8 ::1
        Allow from all
        # AuthUserFile /etc/munin/munin-htpasswd
        # AuthName "Munin"
        # AuthType Basic
        # require valid-user
        <IfModule mod_fastcgi.c>
                SetHandler fastcgi-script
        </IfModule>
</Location>

You will see "Allow from localhost 127.0.0.0/8 ::1" for both munin-cgi-graph and munin-cgi-html. Please comment these lines out and add "Allow from all" (change this depending on your security settings of course) and restart apache2. Now you should be able to zoom to your graphs.
