Since Munin on Ubuntu 14.04 doesn’t work out of the box, here’s a short tutorial how to make it work.

1. Install Munin itself and needed modules:
   
   Shell

   apt-get install munin libapache2-mod-fcgid libcgi-fast-perl

   1	apt-get install munin libapache2-mod-fcgid libcgi-fast-perl

2. Enable mod_rewrite in apache:
   
   Shell

   a2enmod rewrite service apache2 restart

   1 2	a2enmod rewrite service apache2 restart

3. Configure /etc/munin/munin.conf and set these values:
   
   Shell

   libdir /var/lib/munin htmldir /var/cache/munin/www logdir /var/log/munin rundir /var/run/munin graph_strategy cgi cgiurl_graph /munin-cgi/munin-cgi-graph html_strategy cgi

   1 2 3 4 5 6 7 8

   libdir   /var/lib/munin htmldir /var/cache/munin/www logdir /var/log/munin rundir  /var/run/munin   graph_strategy cgi cgiurl_graph /munin-cgi/munin-cgi-graph html_strategy cgi

   
   all other settings can be left as they are.
4. Edit /etc/apache2/sites-enabled/munin.conf and ensure to have a config similar to this:
   
   Apache

   After saving config – reload apache with “service apache2 reload” and munin should be now accessible at munin.hostname.com
