RM Server extensions problem on Azure. Installing extensions on Job Agent?

Hi all,

So I spun up a small VM on Azure with RM Server 8.2 (BYOL). And I copied all the extensions I needed from my local RM Studio 8.2 installtions into /opt/rmserver/plugins. Then I restarted the VM to finish installing those extensions as per documentation and loaded a process. I made all the necessary path changes to the retrive and store operators and any other operators that were grabbing a file or data from my local machine. However process execution fails because it still cannot see those extensions and operators such as Free Memory, and t-SNE and it throws the "Dummy Operator" error. Am I missing something? Also how do I restart only rapidminer server and not the whole VM? It's a linux machine I tried sudo /etc/init.d/rmserver restart but all I get is a systemctl prompt and it waits for me to type something..... I don't know what.

cat /proc/version says I'm running the following distro on the VM if it matters - 

Linux version 3.10.0-862.2.3.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) ) #1 SMP Wed May 9 18:05:47 UTC 2018

There is a note on the documentation page that says the extensions must also be installed on RapidMiner Job Agent. how to do that?

Thank you very much.
