Java Runtime Environment

A Java Runtime Environment (JRE) v8 is required to run the Inductive Ignition platform.  Java can be downloaded for Linux, OSX, and Windows here:

https://www.java.com/en/download/

After downloading follow the instructions to install the JRE.

Note for Linux platforms it may be preferable to use the package manager to perform the installation.  Instructions for some popular Linux platforms are below.

Red Hat Enterprise Linux, CentOS, and Fedora

Begin by using alternatives to install the JRE.  Note if you have multiple JREs installed you will be prompted to select one during the configuration phase.  Make sure to select the newly installed one.

# mkdir /opt/jdk1.8.0_72
# cd /opt/jdk1.8.0_72/
# alternatives --install /usr/bin/java java /opt/jdk1.8.0_72/bin/java 2
# alternatives --config java


There are 3 programs which provide 'java'.
