How to setup SSL for EC2 with ACM?

(I'm an AWS newb)

So I have a running EC2 instance and want to set up the SSL so it can serve HTTPS.

I found a guide from AWS to set up the SSL with external CA, or a brief statement that ACM should be able to work with EC2, but seems not finding any step-by-step guide for this and I expect AWS should have done it with only a few clicks.

Do I need to use the ELB, even though my server is only running in ONE instance?

ACM SSL certs can't be used directly on instances (except enclaves as indicated by Mark in the comments). They can only be used, as in your link, on load balances, CloudFront distro or API gateway. Thus, if you want to use ACM, you have to use either of these three services in-front of your EC2 instance.

But if you don't want to use them, then you need to get your SSL cert from a third party, not from ACM. A popular choice is https://letsencrypt.org/ along with carebot which provide free public SSL certificates. This means that you have to set it up yourself on the instance, usually done through a reverse proxy such as nginx.
