Step One: Install GeoIP Apache Module mod_geoip

This setup was performed on Ubuntu 8.10, PHP 5.26, Apache2, MySQL 5.

Install mod_geoip:

/# apt-get install libapache2-mod-geoip

Or download mod_geoip source files.

Open /etc/apache2/mods-available/geoip.conf and uncomment the GeoIPDBFile

/# vim /etc/apache2/mods-available/geoip.conf

geoip.conf now looks like this:

<IfModule mod_geoip.c>
  GeoIPEnable On
  GeoIPDBFile /usr/share/GeoIP/GeoIP.dat
</IfModule>
