Introduction

By default Piwik uses the provider location to guess a visitor’s country based on the language they use. This is not very accurate, so they recommend installing and using GeoIP.

Requirements

• Ubuntu server
• libgeoip-dev
• Nginx
• Nginx minimal website
• php5-fpm
• php5-dev, php5-geoip, php5-mysql
• Nginx php5-fpm website
• MySQL
• Piwik website

Installation

Download the latest GeoLite database

sudo wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz -P /var/www/[piwik]/misc/

Unzip the database.

sudo gunzip /var/www/[piwik]/misc/GeoLiteCity.dat.gz

Rename the file.

cd /var/www/[piwik]/misc
sudo mv GeoLiteCity.dat GeoIPCity.dat

Update the access rights.

sudo chown www-data:www-data GeoIPCity.dat

Update the php configuration file.

sudo vi /etc/php5/fpm/php.ini

Add the geoip configuration.

geoip.custom_directory = /var/www/[piwik]/misc

Restart Nginx and php5-fpm service.

sudo nginx -t && sudo service nginx reload
sudo service php5-fpm restart

Now open your piwik installation on //[host]/piwik/index.php?module=UserCountry&action=adminIndex and check the GeoIP (PECL) option.

In addition the the GeoLite download url to the Download URL field and click save.
