Installation

Database Setup

Install MongoDB, create a database with authentication. Note the port on which mongo is running.

# In Mongo Shell 
> use torrentDB
> db.createCollection("torrents")
> db.createIndex({ 'ngrams':  'text'})
> db.createIndex({ 'infoHash': 1}, {unique: true})

Add the following environment variables to the ~/.bash_profile and run source ~/.bash_profile

# Any hostname would work, even localhost:port. 
# Necessary to specify port number
export TorrDBHostName="127.0.0.1:27018"  
# Name of the database created with authentication 
export TorrentDB="torrentDB"
# Name of the Collection used by the Libraries, do not change 
export TorrColl="torrents"
# Name of the username with readWrite privileges to $TorrentDB
export TorrDBUserName="user"
# Password for the same
export TorrDBPassWord="password"
