I usually run my rails installation on Cloud9 by typing the following line into my command line: rails server -b $IP -p $PORT
And it launches my environment into a browser. However I've just installed the Radiant CMS, and doing this no longer works. Instead, I'm instructed to do the below:
Your Radiant application is ready to use. Run
script/server -e production
to start the server. Your site will then be running at http://localhost:3000
So I run that line (script/server -e production) in my terminal, and I receive the following (instead of getting my environment):
You may be using the wrong PORT & IP for your server application.
You can still specify the port and IP by using the command:
script/server -e production -b $IP -p $PORT
