Node Js Install Ec2

Introduction: Why Install Node.js on EC2?

If you are a developer who needs to deploy and run a Node.js application, one great option is to use Amazon EC2. Amazon Elastic Compute Cloud (EC2) is a web service that provides secure, resizable compute capacity in the cloud, designed to enable developers to develop and run applications.

Node.js is a popular choice for building server-side applications. It is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside a web browser. Hosting a Node.js application on EC2 can provide you with many advantages, including:

  • Easy scalability
  • Flexible infrastructure options
  • High availability and fault tolerance
  • Pay-as-you-go pricing with no upfront fees

By installing Node.js on EC2, you can take advantage of all of these benefits and more. In this blog post, we’ll walk you through the steps required to install Node.js on an EC2 instance and get your application up and running in no time.

Prerequisites Before Installing Node.js on EC2

Before installing Node.js on EC2, make sure you have the following prerequisites:

  • An active Amazon Web Services (AWS) account.
  • An Amazon Elastic Compute Cloud (EC2) instance configured with the appropriate security settings.
  • A Linux-based operating system running on the EC2 instance (e.g. Ubuntu, Amazon Linux).
  • Sufficient permissions to install software on the EC2 instance.

Additionally, it is recommended to update the package manager on the EC2 instance before installing Node.js. This can be done by running the command:

sudo apt-get update

By ensuring that these prerequisites are met, you can install Node.js on EC2 with confidence.

Installing Node.js on EC2: Step-by-Step Guide

If you’re looking to install Node.js on EC2, then you’ve come to the right place. In this step-by-step guide, we’ll walk you through the entire process, from creating an EC2 instance to installing Node.js and running your first application.

Step 1: Create an EC2 Instance

The first step is to create an EC2 instance. You can do this using the AWS Management Console. Just follow these steps:

  1. Open the EC2 Dashboard.
  2. Click on “Launch Instance”.
  3. Select an Amazon Machine Image (AMI).
  4. Select an Instance Type.
  5. Configure Instance Details.
  6. Add Storage.
  7. Add Tags (optional).
  8. Configure Security Group.
  9. Review Instance Launch.
  10. Launch Instance.

Step 2: Connect to Your EC2 Instance

After your EC2 instance has launched, you can connect to it using SSH. Here’s how:

  1. Open a terminal window.
  2. Change permissions on your private key file: chmod 400 your_key.pem.
  3. Connect to your instance using SSH: ssh -i your_key.pem ec2-user@your-instance-public-ip.

Step 3: Install Node.js

Now that you’re connected to your EC2 instance, you can install Node.js. Here’s how:

  1. Update system packages: sudo yum update -y.
  2. Download and install the latest Node.js LTS version: sudo yum install -y nodejs.
  3. Verify that Node.js is installed: node -v.

Step 4: Run Your First Node.js Application

Finally, you can run your first Node.js application on your EC2 instance. Here’s how:

  1. Create a new directory: mkdir my-app.
  2. Navigate to the new directory: cd my-app.
  3. Create a new file: touch app.js.
  4. Edit the file and paste in the following code:
  5. const http = require('http');
      const hostname = '';
      const port = 3000;
      const server = http.createServer((req, res) => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'text/plain');
        res.end('Hello, World!\n');
      server.listen(port, hostname, () => {
        console.log(`Server running at http://${hostname}:${port}/`);
  6. Save and exit the file.
  7. Start the application: node app.js.
  8. Test the application by opening a browser and going to http://your-instance-public-ip:3000/.

That’s it! You now have Node.js up and running on your EC2 instance. You can continue to build and deploy your Node.js applications using this setup.

Verifying Node.js Installation on EC2 Instance

Once you have successfully installed Node.js on your EC2 instance, you can verify the installation by running the following commands in your terminal:

  1. node -v: This command will display the installed version of Node.js.
  2. npm -v: This command will display the installed version of npm (Node Package Manager).

If both commands return the version numbers, then your installation was successful. You can now start building your Node.js applications on your EC2 instance.

Updating Node.js on EC2: Best Practices

Node.js is a popular runtime environment for building scalable and high-performance web applications. If you are running your Node.js application on an Amazon EC2 instance, it is important to keep your Node.js version up to date.

Here are some best practices for updating Node.js on EC2:

  1. Backup your application: Before updating Node.js, make sure to backup your application code and data to avoid losing any critical data or configurations.
  2. Check the latest stable version: Always check the Node.js website for the latest stable releases available. Make sure that the version you are about to install is stable and supported.
  3. Use a package manager: To easily update Node.js and its dependencies, use a package manager like NPM or Yarn. These tools will manage the installation and update process for you.
  4. Test your application after updating: After updating Node.js, test your application thoroughly to make sure that it runs smoothly and there are no compatibility issues.

By following these best practices, you can keep your Node.js application on EC2 up to date and reduce the risk of running into issues due to outdated versions.

Troubleshooting Common Install Errors: Node.js on EC2

Node.js is a popular platform for building scalable and fast server-side applications. If you’re running a Node.js application on an Amazon EC2 instance, you may encounter some common installation errors. These errors can often make it difficult to install or run Node.js on your EC2 instance.

If you’re encountering issues when trying to install Node.js on an EC2 instance, here are some common troubleshooting steps:

1. Ensure that your EC2 instance has internet connectivity

Before trying to install Node.js, make sure that your EC2 instance has internet connectivity. If your instance does not have internet connectivity, you will not be able to install Node.js or any other packages via the command line.

2. Check the version of Node.js you’re installing

Make sure that you’re installing the version of Node.js that is compatible with your operating system. Node.js releases new versions frequently, so it’s possible that the version you’re trying to install may not be compatible with your EC2 instance’s version of Linux. Make sure to check the Node.js documentation for the correct version to install.

3. Check if Node.js is already installed

Before installing Node.js, check if it is already installed on your instance. You can do this by running the command node -v in the command line. If Node.js is already installed, this command will return the current version of Node.js. If it’s not installed, the command will return an error.

4. Check your user permissions

Make sure that the user running the Node.js installation has the necessary permissions. Some installations require root access, and if you’re not logged in as the root user, you may not have permissions to install Node.js. You can try using the sudo command to run the installation as the root user.

Following these troubleshooting steps should help you overcome common installation errors when installing Node.js on an EC2 instance.
