How to Install Java Runtime Environment (JRE) on Amazon EC2

As a data scientist or software engineer, working with distributed systems and cloud-based platforms like Amazon EC2 is an integral part of your daily tasks. One common requirement is installing Java Runtime Environment (JRE), a set of software tools used for developing Java applications. This guide will walk you through the steps to install JRE on an Amazon EC2 instance.

Prerequisites

Before you start, make sure you have an Amazon EC2 instance running. This guide assumes you’re working with an Amazon Linux AMI, which is a common choice for many users.

Step 1: Connect to Your EC2 Instance

First, you’ll need to connect to your EC2 instance. You can do this by using an SSH client with the .pem key file for your EC2 instance. Here’s an example command:

ssh -i /path/my-key-pair.pem ec2-user@ec2-198-51-100-1.compute-1.amazonaws.com

Replace /path/my-key-pair.pem with the path to your .pem file, and ec2-198-51-100-1.compute-1.amazonaws.com with the Public DNS of your EC2 instance.

Step 2: Update Your System

Once you’re connected, make sure your system is up-to-date. You can do this by running the following command:

sudo yum update -y

This command updates the package manager to the latest version.

Step 3: Install Java

Now, you’re ready to install Java. The following command will help you install the latest Java Development Kit (JDK), which includes JRE:

sudo yum install java-11-amazon-corretto -y

Amazon Corretto is a production-ready distribution of the Open Java Development Kit (OpenJDK). java-11-amazon-corretto installs JDK 11, which is a currently supported long-term support (LTS) version.

Step 4: Verify the Installation

After the installation process is complete, verify that Java has been successfully installed by running:

java -version

This command should display the installed version of Java.

Conclusion

And there you have it! You’ve successfully installed the Java Runtime Environment (JRE) on your Amazon EC2 instance. This will allow you to run any Java applications or services you may need for your data science or software engineering projects.

Remember that working with Amazon EC2 and other cloud services often involves a lot of moving parts, so it’s important to keep your system updated and configured correctly.

Happy coding!
