Distributed Ticket Reservation System

Group 9 Distributed System term project at IITKGP Spring-2020

How to Run

Note: The project requires python3 (for the backend) and NodeJS (for the client)

1. clone repository and create a new virtual environment using python -m venv venv
2. install dependencies using 'pip install -r requirements.txt'
3. In client/ directory, install dependencies using 'npm install`
4. To run the client, in client/ directory open a new terminal and run npm start . This opens the browser and start the client on localhost:3000
5. To run the reverseproxy, in the reverseproxy directory, run python main.py
6. Open three new terminals in server directory and do as follows:
   1. In first terminal, python main.py
   2. In second terminal, python main.py 8002
   3. In third terminal, python main.py 8003

Make sure that the port numbers are correct. Otherwise, a bind() error will be thrown.
Each of the server replicas will create a sqlite database with its port number as its name.
If a .db file with its port no. already exists, then it won't be recreated.
To reset the database simply delete the .db files from the server directory.
