Prerequisites

1. AWS EC2 Instance

   • Instance Type: t2.micro (or higher, based on requirements)
   • Operating System: Ubuntu 20.04 (or your preferred OS)

2. Mobaxterm

   • Used for SSH access to the EC2 instance.

3. Java Development Kit (JDK)

   • Ensure Java is installed on the instance.

4. MySQL Server

   • Installed for the database layer.

5. Maven

   • Used for building and packaging the Java application.

Setup Instructions

1. Launch an EC2 Instance

• Create and start an EC2 instance with the necessary security group settings.
• Allow inbound traffic on ports 22, 8080 (HTTP).

2. SSH into the EC2 Instance

Use Mobaxterm or your preferred SSH client to connect to the instance:

ssh -i your-key.pem ubuntu@<public-ip>

3. Install Java

Install Java to support the application:

sudo apt update
sudo apt install openjdk-11-jdk -y

4. Install MySQL Server

Set up the database server:

sudo apt install mysql-server -y

Log in to MySQL:

sudo mysql -u root

Change the root user password:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'Test@123';
FLUSH PRIVILEGES;

5. Create the Database

Run the following commands to create and configure the database:

CREATE DATABASE bankappdb;
USE bankappdb;
-- Add necessary SQL queries to populate tables
SHOW DATABASES;
SHOW TABLES;

6. Build the Application

Clone the project and build it using Maven:

mvn compile
mvn test
mvn package

Navigate to the target folder to verify that the .jar file was created.

7. Run the Application

Start the application using the following command:

java -jar target/<filename>.jar

The application will start on the Tomcat server, accessible on port 8080.

8. Access the Application

Access the application in a web browser using the EC2 Public IPv4 address and port 8080:

http://<EC2-Public-IPv4>:8080
