How to Install Oracle Java 8 on Ubuntu 14.04 LTS

Pre-Flight Check
  • These instructions are intended specifically for installing Oracle Java 8 on Ubuntu 14.04 LTS.
  • I’ll be working from a Liquid Web Core Managed Ubuntu 14.04 LTS server with Apache and PHP installed, and I’ll be logged in as non-root user. If you need more information then visit our tutorial on How to Add a User and Grant Root Privileges on Ubuntu 14.04 LTS.

Step #1: Add the WebUpd8 Team Personal Package Archive (PPA)

Add the PPA:

sudo apt-add-repository ppa:webupd8team/java

Note: Personal Package Archives include unsupported packages and are untrusted by the primary Ubuntu branch. At the time of publication, the WebUpd8 Oracle Java PPA is an installer (meaning it does not include any Oracle Java binaries, but will download and install them). Use this PPA at your own risk.
Step #2: The Installation

As a matter of best practice we’ll update our packages:

sudo apt-add-repository ppa:webupd8team/java

Update apt-get once more:

sudo apt-get update

Kick off the installer to completely install Java from the PPA.

sudo apt-get install oracle-java8-installer

Be sure to accept the Oracle license!

Step #3: Verify Installation

Now verify that Java is installed and is of version 1.8.x:

java -version

Your result should be similar to:

Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

Temporarily Set the JAVA_HOME variable

Use the export command for the JAVA_HOME variable to show up as an environmental variable, one that can be used by future child processes:

export JAVA_HOME=/usr/lib/jvm/java-8-oracle

 

Permanently Set the JAVA_HOME variable

vim ~/.bashrc

Insert the following into the bottom .bashrc file:

JAVA_HOME=/usr/lib/jvm/java-8-oracle
export JAVA_HOME
PATH=$PATH:$JAVA_HOME

For changes to the .bashrc file to be recognize run the following command:

source ~/.bashrc
