title: How to open a web server port on EC2 instance
body: <p>I'm running a CherryPy web server at <code>0.0.0.0:8787</code> on an EC2 instance. </p>
  
  <p>I can connect to the web server via local <code>wget</code> on the EC2 machine, but I can't reach the instance from my own remote machine (I connect to EC2 via ssh).</p>
  
  <p>Do I need to open up port 8787 to access the web server remotely? If so, how can this be done?  Also, can I use the public IP of the EC2 instance for this?</p>
