Munin Virtual Host Configuration on Ubuntu 14.04 and Apache 2.4

Submitted on Jul 09, 2014, 1:26 p.m.

Having switched to Nginx a while ago, I was recently asked to use Apache for a client installation. There have been some significant changes in 2.4 from 2.2, include the 'Requires' option. I also wanted to create a virtualhost entry for Munin on this machine. It took a little while to figure this out, in particular on Apache 2.4. I'm also using the built-in cron task to generate graphs. Here's the complete Virtualhost configuration for Munin on Ubuntu 14.04 and Apache 2.4

<VirtualHost *:80>
    ServerName munin.yourhost.com
    ServerAlias munin
    ServerAdmin  yours@email.com
    DocumentRoot "/var/cache/munin/www"
    DirectoryIndex index.html 

    <Directory "/var/cache/munin/www">
        AuthUserFile /etc/apache/htpasswords
        AuthName "admin"
        AuthType Basic
        require valid-user
    </Directory>


    ErrorLog  /var/log/apache2/munin.yourhost.com-error.log
    CustomLog /var/log/apache2/munin.yourhost.com-access.log combined
