EC2 服务器实例在端口 8787 上运行 RStudio 超时

Question

I am attempting to run RStudio on an AWS EC2 instance, but it keeps timing out. I am currently following the instructions in this post ( https://aws.amazon.com/blogs/big-data/running-r-on-aws/ ).

From my research, I realize that this is most often a security group issue.

My instance has access to SSH port 22 and Custom TCP port 8787. I've been troubleshooting using this link ( https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html#TroubleshootingInstancesConnectionTimeout ).

I have tried using both default VPC and my own, both of which have the following su.net.network ACL rules.

However, my public IPVv4 DNS ( http://ec2-18-234-130-212.compute-1.amazonaws.com/ ) keeps timing out. I cannot access the login page.

A friend who set up their instance using the first link was successful, and as far as I can tell, I have done everything the same.

Any help is greatly appreciated!

Answer 1

Your RStudio works fine . In your URL you have to provide port number : 8787

http://ec2-18-234-130-212.compute-1.amazonaws.com:8787

As you wrote in the question, it seems you are using the link without the port number.

ps

As you've setup it currently, your traffic to RStudio goes unencrypted over HTTP. If you are not fine with that, a quick fix would be to use ssh tunnel from the instance to your local workstation. With this can close port 8787 as all traffic goes over port 22 and ssh.

Answer 2

Do you access the login page in web browser? If you doing that, you forgot to open port 80/443
