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)
1. Download Java
Download correct version of Oracle Java Developers Kit (JDK) for your operating system. For RHEL "rpm" file is expected.
1.1. 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
2. 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)
