I've installed rvm, ruby, rails, passenger, and nginx using this tutorial. However, I've installed it all over ssh connecting with myusername@machine-ssh-url. So now I've started nginx using
service nginx start
But I'd like to make sure it's working before moving on. The tutorial states "nginx is now on. You can see the exciting “Welcome to nginx” screen in your browser if you point it toward http://youripaddress/". But I'm not sure how to get the IP address of the machine I've ssh'd into, and I'm pretty sure I need to take more steps to allow an internet connection to be established.
I'm rather new to web development and deployment so I'd appreciate a pointer in the right direction as to the next steps to make my new nginx webserver accessible?
