$ virtualenv gazelledb
$ cd gazelledb
$ source bin/activate
(env)$ pip install flask
(env)$ pip install pymongo
(env)$ pip install numpy
(env)$ pip install coloredlogs
First, start MongoDB database server:
$ cd project/root/path
$ mongod --config data/mongodb.conf
Then, activate the virtual Python environment and start the web server:
$ source bin/activate
(env)$ python gazelledb/server.py
If you want to shut down the web server, close it and exit the environment:
[press ctrl-c]
(env)$ deactivate
Optionally you can also open Mongo console:
$ mongo
