To deploy the server, there are a few things we need to do. Firstly, we need to setup the database using postgresql, then run the different server modules.

Database Setup

Firstly, we need to create a new user. To create a new user follow these steps:

$ sudo -i -u postgres
$ psql
postgres=# CREATE USER opinator WITH PASSWORD 'opinator';
postgres=# CREATE DATABASE opinator;
postgres=# GRANT ALL PRIVILEGES ON DATABASE opinator to opinator;
postgres=# \q

After creating new user, login to psql shell with the new user as: psql -d opinator -U opinator

It might show an error psql: FATAL: Peer authentication failed for user "opinator" . In that case please follow the guidelines given here.

After these things are done, we need to create db. To do that:

$ export DATABASE_URL=postgresql://opinator:opinator@localhost:5432/opinator
$ python createdb.py

This will setup the database required for the project.

Run Flask Server

$ cd analyzer/
$ export _JAVA_OPTIONS="-Xmx1024M"
$ python corenlp.py

##Run Scrapyd Server

$ cd scraper $ scrapyd

Then open another terminal and do:
