How to Install Java 14 on CentOS/RHEL 7/8 & Fedora

Java is a secure, stable, and well known, general-purpose programming language and computing technology platform with many interconnected capabilities.

To run Java-based applications, you must have Java installed on your server. You mostly need the Java Runtime Environment (JRE), a collection of software components used to run Java applications on the Linux machine.

If you want to develop software applications for Java, you need to install the Oracle Java Development Kit (JDK), which comes with a complete JRE package with tools for developing, debugging, and monitoring Java applications and it is an Oracle’s supported Java SE (Standard Edition) version.

Note: If you are looking for an open-source and free JDK version, install the OpenJDK which provides the same features and performance as Oracle JDK under the GPL license.

At the time of writing this article, OpenJDK 11 is the current LTS version of Java to be installed using the following command from the default repositories:

# yum install java-11-openjdk-devel
# java -version
Sample Output
openjdk 11.0.8 2020-07-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.8+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.8+10-LTS, mixed mode, sharing)

In this article, we will show you how to install Oracle OpenJDK 14 in RHEL 8/7/6, CentOS 8/7/6, and Fedora 30-32 to develop and run Java applications.

Installing Oracle OpenJDK 14 in CentOS/RHEL and Fedora

To install Oracle OpenJDK 14, you need to download the production-ready OpenJDK 14 from the Java SE Downloads page or run the following wget command to download and install it as shown.

Install the package using the following command:

# yum localinstall jdk-14.0.2_linux-x64_bin.rpm

  1. Is there something wrong with the Fedora package?

    After installing the package with rpm -Uvh jdk-7u25-linux-x64.rpm the following command would not list it:

    alternatives –config java

    Only shows one and that’s openjdk

    java -version gives me open jdk.

    Installing the package again (no errors or warnings the first time) tells me it already installed.

    I’ll try a reboot and see if that helps,.
