Getting Started

Prerequisites

Before you begin, ensure you have the following installed:

Java (JDK 11 or later)
Maven
MySQL
Your favorite IDE (IntelliJ, Eclipse, etc.)

1-Click Local Installation Windows | Linux

Windows

Open a Command Prompt with administrator privileges.
Navigate to the project's installers folder.
Run the install.bat file by double-clicking on it or using the following command:
```
install.bat
```

Linux

Navigate to the project's installers folder.
Run the install.sh using the following command:
```
chmod +x install.sh
./install.sh
```
Follow the on-screen instructions.

Local Setup

Clone the repository:

git clone https://github.com/aamitn/URLShortener.git

Apply the Database Schema:

Execute the provided db_schema.sql file to set up the necessary tables and schema for the application. This script will also create the required database.
```
mysql -u your_username -p < path/to/db_schema.sql
```
Update the application.properties file:

Update the application.properties file in the src/main/resources directory with your database configuration.

Build and run the application:

   cd URLShortener
   mvn spring-boot:run

Access the application at http://localhost:8080

Deployment

Build a deployable WAR:
```
mvn clean install
```
Deploy the WAR:
- Option 1: Manual Deployment
  
  Deploy the generated WAR file to your Tomcat server. Copy the WAR file to the webapps directory of your Tomcat installation.
```
cp target/shorten.war /path/to/tomcat/webapps/
```
- Option 2: Web Interface Upload
  
  Alternatively, if your Tomcat server provides a web interface for WAR file deployment, follow these steps:
  - Access the Tomcat Manager web interface at http://localhost:8080/manager/html (replace with your Tomcat server address).
  - Log in with your Tomcat manager credentials.
  - Navigate to the "WAR file to deploy" section.
  - Choose the shorten.war file using the file upload button.
  - Click the "Deploy" button.
Configure environment variables:

Set environment variables for cloud-specific settings.
Adjust Tomcat Configuration (Important):

To ensure proper functionality, it's important to run the application on the root of the servlet container. If you're using Tomcat, add the following line to your server.xml configuration file within the <Host> section:
```
<Context path="" docBase="shorten" reloadable="true"></Context>
```
This ensures that the application runs on the root context path. Adjust the docBase attribute according to your deployment directory.

Start Tomcat:

Start your Tomcat server.

/path/to/tomcat/bin/startup.sh   # for Linux
/path/to/tomcat/bin/startup.bat  # for Windows

Access the application at http://localhost:8080/.

Adjust Configuration (Optional): If you need to customize the application configuration after deployment, you can find the application.properties file within the deployed WAR file. THe file can be accesses as :
```
vi /path/to/tomcat/webapps/your-app/WEB-INF/classes/application.properties
```

Cloud Native Deployment
