How to Install Oracle Java 8 on Ubuntu 14.04 LTS

• 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 a 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.

Install Oracle Java 8

Add the PPA:

sudo apt-add-repository ppa:webupd8team/java

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)

Optional JAVA_HOME Variable

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
