How to run tomcat7 web app through https over port 8443?

Question

I have a vaadin 7 app running on tomcat 7 on an EC2 server. The app runs through port 8080, so I redirect my domain from 80 to 8080 using:

/sbin/iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

Now, I need to use an SSL certificate that should run on ports 8443 or 443, but checking my port using sudo netstat -nlp, I get this:

So, as I understand, those ports aren't even there...How can I "activate" them and then use them for my https connection?

Answer 1

You are supposed to configure your certificate in your tomcat as shown here . Then you should open those ports in the EC2 console as shown here.
