Amazon EC2: Jetty Unaccessible

Question

I'm trying to install jetty in an Amazon EC2 instance running Ubuntu. The installation seems OK

$ sudo apt-get install jetty

After that I made the parameter NO_START=0 in /etc/default/jetty

Finally

$ sudo service jetty start
    Starting Jetty servlet engine. jetty
    Jetty servlet engine started, reachable on http://ip-xx-xxx-xxx-xxx:8080/
    ...

Nevertheless, when I write in the browser (external computer):

 http://ec2-xxx-xx-xx-xx.compute.amazonaws.com:8080 

The browser could not connect to the address using the given port. I don't know if something is missing during the installation or the URL is wrong.

Thanks for your time and help :-) ,

Answer 1

Each instance on amazon has a security group assigned to it. In the AWS console, select the instance and the security group is shown in the lower pane. Then select security groups on the left and select the group for that instance from the table. In the lower tab, select inbound, these are the IPs addresses/ports allowed in. If 8080 isn't allowed, that's your problem, you need to add it. Enter 8080 in the port range box and 0.0.0.0/0 for the source. Then "add rule" and make sure you "apply rule change" lastly.

I found the answer here: Jetty (mis)configuration: it wont respond from an external machine... why? You need to change /etc/default/jetty to have JETTY_HOST=0.0.0.0
