Advantage:If you want to experiment with something new on Jenkins before you run it in a production environment, this will get you going quickly. If you mess up, just re-install in Nitrous.io and start over.
Step 1:Copy the installation commands from this Jenkins-ci page - https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu to a shell script in the Nitrous.io IDE and run the shell script. You could just run them in the command line if you choose.
Step 2:View Jenkins in the browser by previewing port 8080 as seen in the screenshot
Jenkins will show up on a new browser window. It works!
