Logging into cp.io as a new student


I am new to c9.io and to this community. When log into cloud 9, I see a script which doesn’t appear on my instructor’s screen when he logs into cloud 9. I have a copy of the script below and I have been wondering if I am supposed to ignore it or click on Run as it says. Problem is, when I click on Run, nothing happens. When I type: mysql-ctl nstall nothing happens. I am stuck and frustrated. Please help. Here is the script that I am referring to:

<?php // A simple web site in Cloud9 that runs through Apache // Press the 'Run' button on the top to start the web server, // then click the URL that is emitted to the Output tab of the console

echo ‘Hello world from Cloud9!’;
