RHEL: 1. Install Java

Graphlytic requires Java to be installed. For required version see Requirements. If you have installed required version you can skip installation of Java.

You can test whether you have the correct Java platform by running from command line:

$ java -version
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) Client VM (build 25.65-b01, mixed mode, sharing) 

Download Java

Download correct version of Oracle Java Developers Kit (JDK) for your operating system. For RHEL "rpm" file is expected.

Install Java for RHEL (CentOS)

$ sudo mkdir /usr/java/
$ sudo cp /tmp/jdk-8u66-linux-x64.rpm /usr/java/
$ sudo cd /usr/java/
$ sudo rpm -ivh jdk-8u66-linux-x64.rpm

Confirm that Java Works

Once the steps above have been done, it should be possible to check of java version and see output similar to this:

$ java -version
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) Client VM (build 25.65-b01, mixed mode, sharing)
