= Piwik Web Stats =

This page is to document the [http://piwik.org/ Piwik] server that is to be installed on the DevelopmentServer, the install was done on ticket:160


== Install ==

=== Download ===

{{{
cd /web/
mkdir piwik.transitionnetwork.org
cd piwik.transitionnetwork.org/
wget http://piwik.org/latest.zip
unzip latest.zip
}}}

=== Apache ===

Then set up apache, see /etc/apache2/sites-available/piwik.transitionnetwork.org and run the web installer and:

{{{
cd /web/piwik.transitionnetwork.org/piwik/
chown -R www-data:www-data tmp/
chown -R www-data:www-data config/
}}}

=== MySQL ===

Then a MySQL user and database was added using phpMyAdmin which ran the following SQL:

{{{
CREATE USER 'piwik'@'localhost' IDENTIFIED BY '********';
GRANT USAGE ON * . * TO 'piwik'@'localhost' IDENTIFIED BY '********' WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;
CREATE DATABASE IF NOT EXISTS `piwik` ;
GRANT ALL PRIVILEGES ON `piwik` . * TO 'piwik'@'localhost';
}}}

=== Tracking code ===

The installer suggested this JS tracking code, see the docs at http://piwik.org/docs/javascript-tracking/ :

{{{
<!-- Piwik -->
<script type="text/javascript">
var pkBaseURL = (("https:" == document.location.protocol) ? "https://piwik.transitionnetwork.org.webarch.net/" : "http://piwik.transitionnetwork.org.webarch.net/");
document.write(unescape("%3Cscript src='" + pkBaseURL + "piwik.js' type='text/javascript'%3E%3C/script%3E"));
</script><script type="text/javascript">
try {
var piwikTracker = Piwik.getTracker(pkBaseURL + "piwik.php", 1);
piwikTracker.trackPageView();
piwikTracker.enableLinkTracking();
} catch( err ) {}
</script><noscript><p><img src="http://piwik.transitionnetwork.org.webarch.net/piwik.php?idsite=1" style="border:0" alt="" /></p></noscript>
<!-- End Piwik Tracking Code -->
}}}

And this image tracking code:

{{{
<!-- Piwik Image Tracker -->
<img src="https://piwik.transitionnetwork.org.webarch.net/piwik.php?idsite=1&rec=1" style="border:0" alt="" />
<!-- End Piwik -->
}}}

The following parameters can also be passed to the image URL:

 *   rec - (required) The parameter &rec=1 is required to force the request to be recorded
 *   idsite - (required) Defines the Website ID being tracked
 *   action_name - Defines the custom Page Title for this page view
 *   idgoal - The request will trigger the given Goal
 *   urlref - The Referrer URL: must be set to the referrer URL used before landing on the page containing the Image tracker. For example, in PHP this value is accessible via
    {{{$_SERVER['HTTP_REFERER']}}}
 *   revenue - Used with idgoal, defines the custom revenue for this conversion

=== Logo ===

Customise the logo:

{{{
cd /web/piwik.transitionnetwork.org/piwik
chown -R www-data:www-data themes/
}}}

=== Cron ===

Set up the [http://piwik.org/docs/setup-auto-archiving/#toc-linuxunix-how-to-setup-a-crontab-to-automatically-archive-the-reports crontab to automatically archive the reports]:

{{{
crontab -u www-data -e

5 * * * * /web/piwik.transitionnetwork.org/piwik/misc/cron/archive.sh > /dev/null
}}}

=== Python ===

For the Google Analytics data import we need Python 2.6 and we are running with Python 2.5.2, so [http://evan.borgstrom.ca/post/845359613/python-2-6-on-debian-lenny-5-0 following this] a source compile was done on the dev server, however for the live server it would make more sense to follow [http://www.fps-gamer.net/installing-python-2-6-on-debian-lenny/ these instructions and use the debs from testing perhaps]:

{{{
aptitude build-dep python2.5 
cd /usr/local/src
wget http://www.python.org/ftp/python/2.6.7/Python-2.6.7.tgz
tar -zxvf Python-2.6.7.tgz
cd Python-2.6.7
./configure --with-threads --enable-shared
make
make install 
ln -s /usr/local/lib/libpython2.6.so* /usr/lib/
cd /usr/local/src
wget 'http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e'
tar zxvf setuptools-0.6c11.tar.gz
cd setuptools-0.6c11
python setup.py install
cd /usr/local/src
wget "https://gdata-python-client.googlecode.com/files/gdata-2.0.14.tar.gz" --no-check-certificate
tar -zxvf gdata-2.0.14.tar.gz
cd gdata-2.0.14
python setup.py install
purge python-mysqldb
wget "http://downloads.sourceforge.net/project/mysql-python/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz"
tar -zxvf MySQL-python-1.2.3.tar.gz 
cd MySQL-python-1.2.3
vim site.cfg
 mysql_config = /usr/bin/mysql_config
aptitude install libmysqlclient-dev
python setup.py build
python setup.py install
}}}

=== GA Import ===

See python notes above and [http://clearcode.cc/offer/open-source-projects/google2piwik/ Google2Piwik].

{{{
cd /web/piwik.transitionnetwork.org/
wget http://clearcode.cc/google2piwik-1.2.5.tgz
tar -zxvf google2piwik-1.2.5.tgz
cd google2piwik-1.2.5
cp google2piwik.conf.sample google2piwik.conf
}}}

Edit {{{google2piwik.conf}}}:

{{{

== Requirements ==

The [http://piwik.org/docs/requirements/ requirements are]:

 * PHP version 5.1.3 or greater, We highly recommend using at least PHP 5.3 as it is much more memory efficient than previous PHP versions, we have: PHP 5.2.6-1+lenny10 with Suhosin-Patch 0.9.6.2 (cli), when the server is migrated to squeeze we will get a new php, it can wait till then.
 * MySQL version 4.1 or greater, we have 5.0.51a-24+lenny5-log
 * (enabled by default) PHP extension pdo and pdo_mysql, weh have these already installed and they are configured via /etc/php5/apache2/conf.d/pdo.ini and /etc/php5/apache2/conf.d/pdo_mysql.ini
 * PHP GD extension, installed already
 * Increase your PHP memory_limit value in your php.ini config file to be at least memory_limit = 128M, we have 256M already in /etc/php5/apache2/php.ini
