The whole setup of Oracle NoSQL, in my opinion, is bananas. Each time I tried to set it up, something always failed. Luckily, or because of it, some people (oracle) create a script to facilitate the configuration. The script can be downloaded by cloning this repo:
In this repo, there is a folder called: cluster_setup into which, there is a script called: cluster_setup.sh, they should really come up with a better names :)
Either way, so in our case, we will just configure 2 VMs (using vagrant) and run that setup.
I have done it many times, but the setup of the VMs using vagrant is pretty easy. I have created the following Vagrantfile, based on another Vagrantfile for other shenanigans:

As, maybe, you will guess, that will create us 2 Virtual machines, with an additional disk which we will create a volume group, which we will split into 3 and which we will mount each LV to a separate File system…geeesh that is a lot. Anywho, after this, we should have 2 VMs, running and all installed…but the Oracle NoSQL of course
The script pretty much guides you through the entire process, but let's set the steps:
There might be some issues with the JAVA, don't ask me….Oracle
