AlmaLinux is a rock-solid, server-focused distribution from the enterprise Linux<\/a> family\u2014perfect for anyone who wants a stable, predictable platform they can count on. And while it\u2019s built with servers in mind, it also works very well as a desktop system.<\/p>\n\n\n\n

Now, if you’re a Java developer or just need a reliable environment to run your Java applications and have chosen Alma 10 for a platform, the first question you’re probably asking is: How do I install Java on AlmaLinux?<\/em> Well, you’re in the right place.<\/p>\n\n\n\n

In this guide, I\u2019ll walk you through the process step by step. Additionally, we\u2019ll also make sure your system is set up properly by covering how to configure the necessary environment variables so your Java installation is fully ready to go.<\/p>\n\n\n\n

OpenJDK vs. Oracle JDK<\/h2>\n\n\n\n

Before we get started, I want to clear something up. In other guides, you might see instructions for installing the Oracle version of Java. But here, I\u2019ve chosen not to cover that for a reason\u2014and here\u2019s why.<\/p>\n\n\n\n

First and foremost, the version of Java available in the AlmaLinux 10 repositories is licensed under GPLv2, which means it\u2019s completely free to use\u2014even for commercial purposes.<\/p>\n\n\n\n

Oracle\u2019s version, on the other hand, is distributed under their No-Fee Terms and Conditions<\/a> (NFTC). While that may seem straightforward at first glance, there are some hidden caveats in the license that developers and organizations should be aware of before using it in production.<\/p>\n\n\n\n

First and foremost, no-fee is different from open source. I mean, Oracle JDK under NFTC is not open source, so you\u2019re\u00a0not allowed to modify or redistribute\u00a0the source code. In AlmaLinux, you can use Java commercially, modify it, and redistribute original or modified builds.<\/p>\n\n\n\n

With Oracle JDK, while it permits free internal and production use and redistribution of\u00a0unmodified\u00a0binaries, you can\u2019t distribute modified builds<\/strong>, and the no-fee period is\u00a0time-boxed per release line. So, in practice, Oracle implementation does not give you anything more – both share the same upstream, I mean, both are built from the OpenJDK code.<\/p>\n\n\n\n

With that said, the choice is pretty clear: OpenJDK. Now that we\u2019ve cleared that up, back to the main topic of this guide.<\/p>\n\n\n\n

Choosing the Right Java Package in AlmaLinux 10<\/h2>\n\n\n\n

Before we jump into installing Java on AlmaLinux 10, there\u2019s one more thing worth clearing up\u2014picking the right OpenJDK package. The distro offers three main variants, so allow me to break down what each one does quickly. That way, you\u2019ll know exactly which one makes the most sense for your needs.<\/p>\n\n\n\n
