Step 2: Access the Lightsail Console

1. Log in to your AWS account.

2. Navigate to the Lightsail console by selecting "Lightsail" from the services menu.

Step 3: Create a New Instance

1. Click on “Create Instance.”

2. Choose your instance location (select a region close to your target audience).

3. Select an instance image:

• For Node.js applications, you can choose the "Node.js" blueprint or a Linux/Unix image if you prefer manual setup.

1. Choose your instance plan based on your resource needs (CPU, RAM, storage).

1. Name your instance and click “Create Instance.”

Step 4: Connect to Your Instance

Once your instance is running:

1. Click on the instance name in the Lightsail console.

2. Under the “Connect” tab, choose “Connect using SSH.” You can use the built-in SSH client or an external one like PuTTY or Terminal.

Step 5: Set Up Your Node.js Application

1. Update Your Package Manager:

bash

sudo apt-get update

1. Install Node.js:
   If you chose a plain Linux image:

bash

sudo apt-get install nodejs

sudo apt-get install npm

1. Verify Installation:
   Check that Node.js and npm are installed correctly:

bash

node -v

npm -v

1. Create Your Application Directory:
   Navigate to your home directory and create a new folder for your application:

bash

mkdir my-node-app

cd my-node-app

1. Initialize Your Node.js Application:
   Use npm to create a new package.json file:

bash

npm init -y

1. Install Required Packages:
   Install any necessary packages (e.g., Express):

bash

npm install express

1. Create Your Application File:
   Create an index.js file:

bash

touch index.js

1. Write Basic Server Code:
   Open index.js in a text editor (like nano or vim) and add the following code:

javascript

const express = require('express');

const app = express();

 

app.get('/', (req, res) => {

res.send('Hello World!');

});

 

const PORT = process.env.PORT || 3000;

 

app.listen(PORT, () => {

console.log(`Server is running on port ${PORT}`);

});

Step 6: Run Your Application

1. Start your Node.js application:

bash

node index.js

1. Access Your Application:
   Open a web browser and navigate to http://<your-instance-public-ip>:3000. You should see "Hello World!" displayed.

Step 7: Configure Networking

1. Attach a Static IP Address:
   To prevent your IP from changing when you restart your instance:

• Go to the "Networking" tab in the Lightsail console.

• Choose “Create static IP” and follow the instructions.

1. Map Your Domain Name (Optional):
   If you have a domain name, you can map it to your static IP address using DNS records.

Step 8: Set Up Process Management

To keep your application running even after logging out of SSH:

1. Install PM2 (Process Manager):

bash

sudo npm install pm2 -g

1. Start Your Application with PM2:

bash

pm2 start index.js

1. Set PM2 to Start on Boot:

bash

pm2 startup systemd

pm2 save
