geoip-server
Express.js app that resolves domains and IP address to geo data. It uses geoip and free GeoLite database.
Install
node, npm
# provides add-apt-repository
$ sudo apt-get install python-software-properties
# https://launchpad.net/~chris-lea/+archive/node.js/
$ sudo add-apt-repository ppa:chris-lea/node.js
$ sudo apt-get update
# we need to build geoip package
$ sudo apt-get install nodejs nodejs-dev
Database
Install geoipupdate.
$ sudo add-apt-repository ppa:maxmind/ppa
$ sudo apt-get update
$ sudo apt-get install geoipupdate
or compile from source
$ git clone https://github.com/maxmind/geoipupdate
$ cd geoipupdate
$ ./bootstrap

$ [sudo] make install

$ geoipupdate -f geoipupdate.conf -d ./db/
Run
$ npm install .
$ cp config.json.example config.json
$ npm start
Running constantly
I use upstart job (Ubuntu) and monit for that. Make sure you have dbus package installed, this job somehow needs it.
Allow node to bind to port 80
$ sudo apt-get install libcap2-bin
