Test Automation with selenium and testNg

I want to do CI with Jenkins. I also want to use selenium and TestNg for testing automation. My Jenkins is running in Ubuntu . Can anyone suggest me how to install Selenium and TestNg in Ubuntu. or Can I install both in windows machine and perform the test inside Jenkins machine which is inside the server? if yes please tell me how can I refer the windows server from Jenkins which is running with the Ubuntu machine. Please consider both machine are in AWS cloud.

Thanks in Advance.
