Mastering JDK 17 Installation on Linux & Amazon EC2

Installing JDK 17 is a critical first step for building modern Java applications on the cloud. Whether you are using a local Linux server or an Amazon EC2 instance, this guide will show you how to get it done efficiently using the command line.

Step 1: System Preparation

Before installing new software, always update your package repository to ensure you have the latest security patches and metadata. Execute these commands:

sudo yum update -y
sudo yum upgrade -y

Step 2: Download the JDK 17 Archive

We will use wget to download the Linux x64 Compressed Archive directly from Oracle's servers. This method gives you total control over the installation location.

wget [ORACLE_JDK_17_DOWNLOAD_LINK]

Step 3: Installation & Directory Setup

Extract the downloaded .tar.gz file into the /opt directory. The /opt folder is the standard place for third-party software on Linux.

sudo tar -xvf jdk-17_linux-x64_bin.tar.gz -C /opt

Step 4: Configure the Environment

To make the java and javac commands work from any folder, you must edit the system profile. Open /etc/profile and add your new JAVA_HOME path:

export JAVA_HOME=/opt/jdk-17.0.x
export PATH=$PATH:$JAVA_HOME/bin

Reload the configuration by typing: source /etc/profile

Step 5: Final Check

Confirm the installation was successful by checking the version number in your terminal:

java -version
