Setting up a Java environment on the cloud is a fundamental skill for modern developers. Whether you are deploying a microservice or a web application, having the right JDK version on your Linux server is crucial. This guide makes the process incredibly simple.
Why Use OpenJDK on Linux?
OpenJDK is the open-source implementation of the Java Platform. It is the default version found in most Linux distributions and is highly optimized for server environments like Amazon EC2. Versions 11 and 17 are Long-Term Support (LTS) releases, meaning they are stable and reliable for production use.
Step 1: Connect to Your Instance
First, log in to your Amazon EC2 instance using SSH. Make sure your system is up to date by running the update command. This ensures all your package repositories are refreshed.
Step 2: Search for Available Java Versions
You can list the available OpenJDK packages in your repository. Look for java-11-openjdk or java-17-openjdk. Using the package manager makes installation and future updates a breeze.
Step 3: Simple Installation Command
Once you've identified the version you need, use the install command. For example, to install OpenJDK 11, you would typically use sudo yum install java-11-openjdk (on Amazon Linux/RHEL) or sudo apt install openjdk-11-jdk (on Ubuntu).
Step 4: Verify the Success
After the process finishes, always verify the installation. Type java -version in your terminal. You should see the OpenJDK version details printed clearly, confirming your environment is ready!
