This article will help you to install Oracle Java 11 on CentOS 7 and Fedora 29. Java 11 is a long-term support (LTS) release. Java 11 was made available to the General public on 25 September 2018 and is production-ready.

There are two ways of installing Java 11 on CentOS 7 / Fedora 29 & Fedora 28.

  1. Install Java SE Development Kit 11 (JDK 11)
  2. Install OpenJDK 11

It is recommended to install OpenJDK 11 because of the license issues around Java SE Development Kit. This guide will cover the installation of both.

Install OpenJDK 11 on CentOS 7 / Fedora 29 / Fedora 28

OpenJDK is a free and open-source implementation of the Java Platform, Standard Edition licensed under the GNU General Public License version 2.

After the download, extract the archive

tar zxvf openjdk-11.0.1_linux-x64_bin.tar.gz

Move the resulting folder to /usr/local/

sudo mv jdk-11* /usr/local/

Set environment variables

sudo vim /etc/profile.d/jdk.sh

Add:

export JAVA_HOME=/usr/local/jdk-11.0.1
export PATH=$PATH:$JAVA_HOME/bin

Source your profile file and check java command
