EC2实例上的HTTPS

Question

I have an EC2 instance on Amazon (AWS). The instance is behind a ELB (Elastic Load Balancer). I want to allow HTTPS connections to reach the EC2 instance.

Is it necessary to have the load balancer configured for HTTPS, ie, to check the certificates etc, or can this just be done traditionally within the EC2 instance and virtual host SSL configuration ?

The reason I'm asking is because I have allowed traffic via ELB -> EC2 for port 80 and 443, but only port 80 reaches the instance.

EDIT

Nmap scan report for localhost (127.0.0.1)
Host is up (0.00021s latency).
Not shown: 996 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
80/tcp   open  http
443/tcp  open  https
3306/tcp open  mysql

EDIT 2

Here is my other stack overflow questions explaining the bigger problem I have, hence why I opened this question. HTTPS only works on localhost

Answer 1

Check whether any application is running on port 443.

Use this command to check:

nmap -sT -O localhost

EDIT

Add the certificate files on the server and then upload them to IAM using the command:

aws iam upload-server-certificate --server-certificate-name my-server-cert --certificate-body file://my-certificate.pem --private-key file://my-private-key.pem --certificate-chain file://my-certificate-chain.pem
