How to open a web server port on EC2 instance

Question

I'm running a CherryPy web server at 0.0.0.0:8787 on an EC2 instance.

I can connect to the web server via local wget on the EC2 machine, but I can't reach the instance from my own remote machine (I connect to EC2 via ssh).

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?

Answer 1

Follow these steps to do this:

• Open "Network & Security" -- Security Group settings are on the left-hand navigation
• Find the security group connected to your instance
• Choose “inbound rules”
• Type the port number (in your case 8787) in “port range” then click “Add Rule”
• Use the drop-down and add HTTP (port 80)

And it is done.
