Milestones

• Milestone 1 - https://github.com/CS677-Labs/Lab-3-Pygmy-The-book-store/tree/milestone1

Run 2 catalog servers, 2 order servers and 1 frontend server on localhost

cd Lab-3-Pygmy-The-book-store
bash run.sh

To run the system on AWS EC2 instances

Create a config file. This file should have 3 lines.

1st line will contain comma separated list of DNS name/IP of servers where catalog server replicas should run. 2nd line will contain comma separated list of DNS name/IP of servers where order server replicas should run. 3rd line will contain DNS name/IP of server where frontend server should run.

Example :

cat config
ec2-52-204-17-35.compute-1.amazonaws.com,ec2-54-146-69-77.compute-1.amazonaws.com,ec2-54-152-5-125.compute-1.amazonaws.com
ec2-54-157-158-136.compute-1.amazonaws.com,ec2-52-23-179-14.compute-1.amazonaws.com,ec2-107-23-14-212.compute-1.amazonaws.com
ec2-54-237-55-198.compute-1.amazonaws.com

With the above config file 3 replicas of catalog server will run on servers listed on line 1. 3 replicas of order server will run on servers listed on line 2. And front end server will run on server on line 3.

Please ensure there is no extra space in between.

Login to a server that has passwordless ssh set up to all the above servers. Clone the repo and do the below :

cd Lab-3-Pygmy-The-book-store
bash run.sh config
