无法访问EC2实例

Question

I am using AWS and i created Auto scaling launch configuration using shell Script:

#!/bin/sh
curl -L https://us-west-2-aws-training.s3.amazonaws.com/awsu-spl/spl03-working-elb/static/bootstrap-elb.sh | sh

After creating this and the load balancer, two instances were created. I then copied the DNS Name and pasted it in browser, but it says:

This site can’t be reached

internal-elb-asg-167368762.us-east-1.elb.amazonaws.com took too long to respond.
Go to http://amazonaws.com/
Search Google for internal elb asg 167368762 east amazonaws

Answer 1

EDIT

I followed your steps and it failed.

You have to change this part of the User Data:

#!/bin/sh curl -L https://us-west-2-aws-training.s3.amazonaws.com/awsu-spl/spl03-working-elb/static/bootstrap-elb.sh | sh

With this:

#!/bin/sh
curl -L https://us-west-2-aws-training.s3.amazonaws.com/awsu-spl/spl03-working-elb/static/bootstrap-elb.sh | sh

Edit: As @john-rotenstein mentioned is not necessary to use sudo.

Also, check this:

• You have the correct security groups on EC2 and with your ELB.
• Check if you are listening to the port 80 in you ELB.
• The port 80 must be opened in your EC2 security group to your ELB security group and the port 80 must be opened worldwide (0.0.0.0) in your ELB security group.

Finally, are you sure that you are not using an internal load balancer right?

Hope it helps you.
