Deploying Node.js with MongoDB Application on AWS EC2 involves several steps, from creating an AWS account to setting up your server and deploying your application. This guide will walk you through the entire process, ensuring you can get your application up and running on AWS EC2 efficiently.ts

Creating an AWS Account

Visit the AWS Website

Go to AWS’s official website.

Sign Up for an AWS Account

Click on the “Create a Free Account” button.Follow the prompts to enter your email address, password, and AWS account name.

Enter Payment Information

Provide your payment details. AWS offers a free tier with limited resources, but you still need to enter billing information.

Verify Your Identity

AWS will ask you to verify your phone number by sending a code via SMS.

Select a Support Plan

Choose the Basic Support plan (free) or another plan based on your needs.

Complete the Setup

Once you complete these steps, you’ll receive a confirmation email, and your AWS account will be ready to use.

Setup EC2 server

VMs on AWS are called EC2 Servers

EC2 stands for Elastic compute Version 2.

1. Elastic – Can increase/decrease the size of the machine
2. Compute – It is a machine

Search for ec2 and click on EC2(Virtual Servers in the Cloud)

Launch an Instance

After click on Ec2 You will see Lauch an Instance as seen in the image below and click on it to create a fresh instance.

Select Operating System and Instance Type

After lanching an instance select Ubuntu in the os and t2.mico instance type Note that you can select a large system as per requirements today in this tutorial we’ll be seleting t2.micro as it is free for first 12 months.

Configure the EC2 server and create .pem file to access your server from your shell

In the network settings select Create security group and tick mark all the buttons.

Then click on create new keypair add keypair name like myblog etc. Use name on your own and check RSA and .pem and click on create keypair button after this a file will be downloaded on you computer

This .pem file is sensitive file which is used for accessing your EC2 server so keep it safe on your computer.

After configuration of our EC2 server click on launch instance button on bottom left. Wait for instance to be launch.

After launch is successful you will see you instance in your EC2 dashboard wait for about 2-3 mins to be initilized.

Connect to your server

After completing all config open you terminal in you systems and go the directory you save the .pem file. Note: if you are using windows make sure you install the git bash https://git-scm.com/downloads.

If your are in the directory you dont need to add path just write ssh -i your-keypair.pem ubuntu@yourpublic ipv4-IP (copy it from your ec2 instance )

you will see the following if you successfully ssh into your server.

Setting Up the Server

Update and Install Required Packages

After connecting to your instance, update your package list and install necessary tools: write the following commands in your shell one by one.

sudo apt update
sudo apt upgrade -y
sudo apt install -y nodejs npm

Install MongoDB

Follow the official MongoDB installation instructions for Ubuntu or Amazon Linux. For Ubuntu, the commands are:

wget -qO – https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add –
echo “deb [ arch=amd64 ] https://repo.mongodb.org/ubuntu focal 10gen” | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
sudo apt update
sudo apt install -y mongodb-org

Start MongoDB:

sudo systemctl start mongod
sudo systemctl enable mongod

Deploying Your Node.js Application

Clone Your Repository

If your code is hosted on GitHub, clone it to your EC2 instance:

git clone https://github.com/yourusername/your-repo.git
cd your-repo

Install Dependencies

Navigate to your project directory and install the necessary dependencies:

npm install

Configure Your Application

Update your application configuration to connect to the local MongoDB instance. Modify your config.js or .env file with the MongoDB connection string:

Create .env file in you project directory:

sudo nano .env (add all your envireonment variables that your project depend upon e.g PORT,MONGO URL etc)

Start Your Application

Run your Node.js application:

npm start

To ensure your application continues running after you disconnect, use a process manager like PM2:

sudo npm install -g pm2
pm2 start app.js (name is optional you can also give pm2 start “startmyserver”)
pm2 startup
pm2 save

Review your deployement

Now to go AWS dashboard and go to your EC2 instances click on your instance and in below settings click on security then click on security groups ,click on edit in bound rules add 2 new rules select custom TCP your PORT and Anywhere ipv4 adresss and in the other one select any ipv6 address. as shown in the image below.

Ensure your Application is running

Go to your browser and write your public ip:your port e.g 12.45.23.11:3000

Configure Nginx

To serve your application through Nginx, install Nginx and configure it as a reverse proxy:

Install Nginx

sudo apt install -y nginx

Configure Nginx

Create a new configuration file in /etc/nginx/sites-available/:

sudo nano /etc/nginx/sites-available/myapp

Add the following configuration: note: add your own IP and PORT

location / {
    proxy_pass http://localhost:3000; 
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}

Enable the configuration and restart Nginx:

sudo ln -s /etc/nginx/sites-available/myapp /etc/nginx/sites-enabled/
sudo systemctl restart nginx

Verify Your Deployment

Open a web browser and navigate to your EC2 instance’s public IP or domain name. You should see your Node.js application running. Now access you ip in the browser without defining the port.

Conclusion (Deploying Node.js with MongoDB Application on AWS: Complete Tutorial for Developers)

You’ve successfully created an AWS account, set up an EC2 instance, installed MongoDB, deployed your Node.js application, and optionally configured Nginx. With this setup, you can now manage and scale your application as needed on AWS. If you encounter any issues or need further customization, AWS documentation and community forums can provide additional guidance.
