In this Chapter, we are going to setup a Histraffic Server
https://rethinkdb.com/docs/install/ This link provides very straight forward insturctions on how to setup RethinkDB server. Simply follow those steps and you will be ok.
Our program uses Rethinkdb Python Client. Follow the instructions on https://rethinkdb.com/docs/install-drivers/python/ and install it.
First clone the source code
git clone..
python setup.py installRun the file in interactive shell
