How to Install Node.js on Amazon EC2: A Step-by-Step Guide

In the realm of web development, Node.js is a critical tool. This runtime allows you to execute JavaScript on your server, making it essential for developers who are building web applications. However, installing Node.js on an Amazon EC2 instance can be a bit tricky if you’ve never done it before. In this blog post, we’re going to demystify the process with a step-by-step guide.

Prerequisites

Before we dive into the installation process, ensure that you have the following:

1. An Amazon EC2 instance running.
2. SSH access to your instance.
3. Basic knowledge of command-line tools.

Step 1: Update Your EC2 Instance

The first thing you want to do is ensure your EC2 instance is up-to-date. This is important for the security and performance of your server. Use the following command to update your instance:

sudo yum update -y

Step 2: Install Node Version Manager (NVM)

Next, we’re going to install the Node Version Manager (NVM). This tool allows you to manage multiple versions of Node.js on your server. Execute the following command to download and install NVM:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

This command fetches the NVM installation script from its GitHub repository and executes it.

After the installation, you need to activate NVM using the following command:

. ~/.nvm/nvm.sh

You can verify NVM’s installation with:

nvm --version

Step 3: Install Node.js

With NVM installed, you can now install Node.js. NVM allows you to install many versions, but for this guide, we’ll install the latest stable version. Use the following command to do so:

nvm install node

You can verify the Node.js installation with:

node --version

Step 4: Install NPM

Node.js comes with the Node Package Manager (NPM), so if you’ve successfully installed Node.js, NPM should already be available. You can verify this with:

npm --version

Step 5: Test Node.js and NPM Installation

To confirm that Node.js and NPM are correctly installed, you can create a simple “Hello, World!” program.

Begin by creating a new JavaScript file:

nano hello.js

This command opens a text editor. Input the following JavaScript code:

console.log('Hello, World!');

Save the file and exit. You can now run your Node.js program with the following command:

node hello.js

If everything is working correctly, you should see “Hello, World!” output in your console.

Wrapping Up

And that’s it! You now have Node.js and NPM installed on your Amazon EC2 instance. From here, you can start building your Node.js applications, secure in the knowledge that you have a flexible and powerful runtime at your disposal.

Remember, Node.js is an actively developed platform, so make sure to keep your installation up-to-date with the latest security patches and performance improvements. Happy coding!
