Apache virtualhost configuration

This example describes how to set up munin on a separate apache httpd virtual host. It uses FastCGI if this is available, and falls back to CGI if it is not.

Munin configuration

This example assumes the following configuration in /etc/munin/munin.conf

graph_strategy cgi
html_strategy  cgi

Virtualhost configuration

Add a new virtualhost, using the following example:

<VirtualHost *:80>
    ServerName munin.example.org
    ServerAlias munin

    ServerAdmin  info@example.org

    DocumentRoot /srv/www/munin.example.org

    ErrorLog  /var/log/apache2/munin.example.org-error.log
    CustomLog /var/log/apache2/munin.example.org-access.log combined

    # Rewrites
    RewriteEngine On

    # Static content in /static
    RewriteRule ^/favicon.ico /etc/munin/static/favicon.ico [L]
    RewriteRule ^/static/(.*) /etc/munin/static/$1          [L]

    # HTML
    RewriteCond %{REQUEST_URI} .html$ [or]
    RewriteCond %{REQUEST_URI} =/
    RewriteRule ^/(.*)          /usr/lib/munin/cgi/munin-cgi-html/$1 [L]

    # Images
    RewriteRule ^/(.*) /usr/lib/munin/cgi/munin-cgi-graph/$1 [L]

    # Ensure we can run (fast)cgi scripts
    <Directory "/usr/lib/munin/cgi">
        Options +ExecCGI
        <IfModule mod_fcgid.c>
            SetHandler fcgid-script
        </IfModule>
        <IfModule !mod_fcgid.c>
            SetHandler cgi-script
        </IfModule>
    </Directory>
</VirtualHost>
