Piwik

Installation

cf http://piwik.org/

apt-get install php5-gd
/etc/init.d/apache2 restart
wget http://piwik.org/last.zip

Unzip it under e.g. <your website>/piwik
And prepare a Mysq database:

mysql> create database piwik;
Query OK, 1 row affected (0.00 sec)
mysql> GRANT ALL ON piwik.* TO piwik@localhost IDENTIFIED BY 'piwikpassword';
Query OK, 0 rows affected (0.00 sec)

Piwik needs write access to some parts of the install in piwik/:

mkdir tmp
chown www-data:www-data config tmp

Now you can visit http://<your website>/piwik and follow instructions to add the first site.
For more than one site, log in and check admin/sites
