Step-by-Step‍ Guide to Deploying Node.js Apps on AWS EC2

Deploying your Node.js application on a⁤ reliable, scalable cloud⁢ platform​ can elevate your project to⁢ new heights. Amazon Web Services (AWS)‌ Elastic​ Compute Cloud (EC2) offers a ⁣flexible environment to host your Node.js apps with full control and scalability. In⁤ this ​extensive guide,we’ll walk ⁣you through every​ step—from launching an EC2 instance to deploying and managing your Node.js⁤ app efficiently.

Why Deploy Node.js Apps on AWS EC2?

AWS ⁣EC2 provides a secure, robust, and ‌scalable infrastructure perfect for hosting Node.js applications. here are ⁢some‌ key ‌benefits:

Prerequisites

Before we dive ⁢in, ensure ‍you have​ the following:

Step⁢ 1: launch an AWS⁣ EC2 ‍Instance

Start by provisioning⁣ a virtual⁤ server ⁤were your Node.js app will run.

  1. Log in to the AWS Management Console.
  2. Navigate to EC2 ⁤Dashboard and click Launch Instance.
  3. Choose an Amazon Machine Image (AMI): Select the⁤ latest Amazon Linux 2 AMI ⁢ or​ Ubuntu Server 22.04 LTS.
  4. Choose Instance Type: For small apps, t2.micro (which ⁣is eligible for AWS Free Tier) is sufficient.
  5. Configure ⁢Instance ⁤Details: Keep default, or customize VPC and subnet if ⁢needed.
  6. Add Storage: 8-20 GB is typically ​enough for most Node.js apps.
  7. Add Tags: ⁤ optionally add Name tag for⁣ easy reference (e.g.,NodejsAppServer).
  8. Configure Security Group: Add rules to allow SSH (Port ⁣22) and‌ HTTP (port 80)​ or HTTPS (Port ​443) depending on your app’s protocol.
  9. Review and click ⁢ Launch, then create or select an existing key ‍pair for SSH access.

Step‌ 2: Connect to Your EC2 ‌Instance via SSH

Use your SSH ‍client to access the server:

ssh -i /path/to/your-key.pem ec2-user@your-ec2-public-ip

Note: Replace ec2-user with ubuntu if using an Ubuntu AMI,and replace the key path and IP accordingly.

Step⁢ 3: Install Node.js and Git

Once connected, update the packages and ‍install ‍Node.js along ⁢with Git to clone your ​application repository.

For Amazon linux 2:

sudo yum update -y

curl -sL https://rpm.nodesource.com/setup_18.x | sudo bash -

sudo yum install -y nodejs git

For‌ Ubuntu:

sudo apt update && sudo apt upgrade -y

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -

sudo apt-get install -y nodejs git

Step 4: Clone Your Node.js Application Repository

Navigate ‍to⁢ the home directory and clone your app’s Git repository:

cd ~

git clone 

cd your-nodejs-app

If you don’t have a Git repository,⁢ you can ⁤also use scp to upload ⁤your files directly.

Step ‌5: Install ​App⁤ Dependencies & run the Application

from ​inside your​ app folder,‍ install dependencies defined in ‍ package.json and ​start your Node.js server:

npm install

node app.js

Note: Replace app.js with your app’s entry ‌file.

Step 6: ⁣Configure⁤ Process Manager (PM2) ⁤for ‍Production

To keep your node.js app running even ‍after you disconnect from SSH or if the server restarts, use PM2 — a production process manager for ‌Node.js.

sudo npm install -g pm2

pm2 start app.js

pm2 startup

pm2 save

This‍ ensures ⁣automatic startup on ‍instance reboot‌ and safe background running.

Step 7: Configure Security Group ⁣& Firewall Rules

Verify that your EC2 instance’s Security Group allows inbound traffic on the ports your app uses (default HTTP:⁢ 80 or custom port). You can⁣ add rules from the ​EC2⁣ console:

TypeProtocolPort ‍RangeSource
SSHTCP22Your ‌IP‍ (or‍ 0.0.0.0/0⁢ temporarily for testing)
HTTPTCP800.0.0.0/0
HTTPSTCP4430.0.0.0/0

Step 8: Setup Reverse Proxy with Nginx (Optional but Recommended)

Using Nginx⁢ as a​ reverse proxy enhances performance and adds SSL/TLS support. Install and configure Nginx to forward ​requests to your ⁣Node.js ⁢app.

Install ⁣Nginx:

sudo yum install nginx -y          # For Amazon Linux 2

sudo apt install nginx -y           # For Ubuntu

Configure Nginx:

Create ​a configuration​ file ​in ​ /etc/nginx/conf.d/ or /etc/nginx/sites-available/:



server {

  listen 80;

  server_name yourdomain.com;



  location / {

    proxy_pass http://localhost:3000;  # Your Node.js port

    proxy_http_version 1.1;

    proxy_set_header Upgrade $http_upgrade;

    proxy_set_header Connection 'upgrade';

    proxy_set_header Host $host;

    proxy_cache_bypass $http_upgrade;

  }

}

Reload Nginx to apply ​changes:

sudo systemctl restart nginx

Conclusion

Deploying ⁤Node.js applications on ⁣AWS EC2 gives developers the power and flexibility to run‌ scalable,secure,and efficient applications in the cloud. ⁤Though the setup process involves several steps ‌like launching ‍instances, installing dependencies, configuring security, ⁢and​ optionally setting up a reverse proxy, the result is a reliable hosting environment tailor-made for ‍your app’s needs.

By using‌ process managers like PM2‌ and services like Nginx, ‌combined with AWS’s robust ⁢infrastructure, you can ensure your Node.js ⁣apps perform optimally in‍ production. follow this guide, and you’ll⁤ have your Node.js app up⁣ and running‌ on⁣ AWS EC2 in no time.
