amazon ec2 - 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 the steps that are described on this answer just instead of using the drop down, type the port (8787) in "port range" an then "Add rule".

Go to the "Network & Security" -> Security Group settings in the left hand navigation

Find the Security Group that your instance is apart of Click on Inbound Rules Use the drop down and add HTTP (port 80) Click Apply and enjoy
