Piwik on Ubuntu 9.10 (Karmic)

Published: by


This document is an older, unmaintained guide. There may be a new guide available for this software.

Piwik is a "downloadable, open source (GPL licensed) web analytics software program." As an alternative to services like Google Analytics, Piwik allows you to host your statistics services on your own server and have full ownership of and control over the data collected from your visitors.

For the purpose of this guide, we assume that you have running and functional server, and have followed the getting started guide. If you are new to administering Linux servers and have questions about basic system usage, you might want to consider the beginners guide and our using Linux documentation for a more complete introduction to Linux.

Beyond the basics, Piwik requires a functioning LAMP stack. You can install the LAMP software with the Ubuntu 9.10 LAMP guide. Make sure you follow the steps for installing PHP and PHP-MySQL support. You will also want to be logged in over SSH as root.



Make sure your package repositories and installed programs are up to date by issuing the following commands:

apt-get update
apt-get upgrade --show-upgraded

Piwik requires a few additional dependencies beyond LAMP fundamentals. Most importantly, Piwik requires the php5-gd package to draw the "sparklines." These are the small graphs displayed in the control panel. We'll also need wget and unzip to access the files in the Piwik package. Install php5-gd and unzip by running the following command:

apt-get install php5-gd unzip wget

Configure PHP Memory Settings

By default, PHP's memory_limit value is set to 64 megabytes. For "medium to high traffic" sites, Piwik's creators recommend setting this value to 128 megabytes. If you choose to follow this recommendation edit the php.ini file so memory_limit setting is as follows:

File excerpt:/etc/php5/apache2/php.ini

memory_limit = 128M

Restart the Web Server

You'll need to restart Apache after installing php5-gd and modifying the PHP settings. You can do this by issuing the following command:

/etc/init.d/apache2 restart

Configure a Dedicated Virtual Host for Piwik

This phase of the installation process is optional, but recommended. Here we configure a subdomain and virtual host configuration in Apache specifically for Piwik. This makes it easy to separate the statistics package from the website or websites that Piwik monitors.

To create a virtual host we need to add an "A Record," for the subdomain that Piwik will use; in our example this is If your DNS is hosted with Linode's DNS servers, you can configure the A record in the DNS manager. Additionally, we'll need to create a new virtual hosting file for this sub domain.

We'll create the following host file, located at /etc/apache2/sites-available/


    DocumentRoot /srv/www/
    ErrorLog /srv/www/
    CustomLog /srv/www/ combined

We'll need to create the logs/ and public_html/ directories by issuing the following commands:

mkdir -p /srv/www/
mkdir /srv/www/

Enable the virtual host and reload the web server's configuration with the following two commands:

/etc/init.d/apache2 reload

Remember that the configuration of a special virtual host for Piwik is optional. If you use a web server other than Apache, you will need to pursue different steps to configure the virtual host.

Installing Piwik

First we'll download the latest distribution of the Piwik package. Issue the following two commands:

cd /srv/www/

Uncompress the archive and move the contents of the archive to the directory where you want to install Piwik. Use these two commands:

mv piwik/* public_html

Before running Piwik's installation script, we need to change the permissions of several directories. Piwik requires these permissions to remain set to function properly. Issue the following commands:

chmod a+w /srv/www/
chmod a+w /srv/www/

Visit your new Piwik instance in your browser. In our example, this is located at Follow the instructions provided by the Piwik installation process. It will prompt you for the name of your MySQL database as well as access credentials for this database. This information was created when you installed the LAMP stack.

When Piwik's installation process is complete, you will receive JavaScript snippet that you can insert in every page on your site that you want to track using Piwik.

If you are concerned about the security of the data collected by Piwik, consider limiting access to Piwik's virtual host, using either rule-based or authentication based access control.

Congratulations! You now have a fully functional statistics and web traffic analytics package running on your own server.
