How to protect Munin Web statistics with password on GNU / Linux

I just installed munin to track in web the performance of few Debian servers. I’ve configured munin to open via a Virtualhosts in Apache. As its always wise to protect any statistics data about the server from the unwanted possible security violators, I decided to protect Munin with Apache .htaccess.

The munin htmldir output dir is configured to be in /var/www/munin, hence I protected my munin with password by:

1. Creating .htaccess file in /var/www/munin with following content

AuthUserFile /etc/apache2/.munin_htpasswd
AuthGroupFile /dev/null
AuthName EnterPassword
AuthType Basic

require user admin

2. Creating /etc/apache2/.munin_htpasswd with htpasswd (htaccess password generator cmd)

debian:/var/www/munin# htpasswd -c /etc/apache2/.munin_htpasswd admin
New password:
Re-type new password:
Adding password for user admin

Another important thing I had to do is set my VirtualHost file to be configured with AllowOverride All , if AllowOverride All is missing the .htaccess and .htpasswd are not red at all.
Afterwards munin is protected with password, and when my virtualdomain where munin lays e.g. http://munin.mydomain.com is accessed the .htpasswd password dialog pops up 😉
