That was mostly perfect and while I installed everything almost exactly like the video:
##modifications were to the install location. I used /var/www instead of /home/ubuntu and I installed Charts.js
Java version is
ubuntu@ip-10-7-130-206:~$ javac -version
javac 1.8.0_151
I also checked my JAVA_HOME variable
ubuntu@ip-10-7-130-206:~$ echo $JAVA_HOME
/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java and that appears good.##
However after starting Knowage via the startup.sh script in /var/www/Knowage-Server-CE/bin/ folder
I get this from my webpage http://54.156.232.37:8080/knowage/
This site can’t be reached
54.156.232.37 refused to connect.
ERR_CONNECTION_REFUSED
note: I tried this on Chrome, Edge, Firefox, and IE 11
-----------------
I thought to do a configcheck from the configcheck.sh script, these are the results:
ubuntu@ip-10-7-130-206:~$ sudo /var/www/Knowage-Server-CE/bin/configtest.sh

Configuration error detected!
Did I miss a step?
