I have an AWS EC2 instance, a Route53 registered domain, an AWS Load Balancer and an AWS Certificate.
What I want to achieve is to access the domain as "https://...", as of today I haven't been able to.
What I've done so far is:
1.- Set the EC2 (Amazon Linux AMI) with apache and it's listening to de ports :80 :443
When I browse to the puclic IP of the EC2 I see index.html no problem.
2.- I have registered a new domain using Route53. I added a Record Set for the Hosted Zone Type IPv4 address with the value of the IP of the EC2 instance.
When I browse to the domain.com I see index.html no problem.
3.- I got an AWS Certificate for *.domain.com and domain.com. For validation I added a Type CNAME Record Set provided to the Hosted Zone of the domain. For both the validation status is OK.
4.- I created a Load Balancer that listens to HTTP:80 and HTTPS:443 and I added a Record Set in the Hosted Zone of the domain with [type:IPv4, Alias:Yes, Alias Target: name of the Load Balancer]. I didn't type the name of the Load Balancer, I selected it from the select dropdown.
However the Load Balancer has the fields Port Configuration and Instance Count blank as you can see in the screenshot.
5.- When I check the file /etc/httpd/logs/ssl_error_log I see a message that I can'f figure out what it means, nothing good I imagine. The text of the message is AH01906: ... as you can see in the next screenshot.
When I browse to https:// domain I get the message that is not safe.
I'm very new to all this and I'm sure I'm doing something wrong but I can't figure out what.
I would appreciate any help or pointer you could give to me.
Thanks very much, this community is awesome anyway.
AWS Certificate Manager does not offer free SSL for website. It does offer free SSL certificate for some of their services endpoint (not the same as using directly on your EC2 instance).
For certificates that you want to install directly on EC2, you have to pay for a private Certificate Authority. (note: its expensive)
Q: With which AWS services can I use ACM certificates?
You can use public and private ACM certificates with the following AWS services:
• Elastic Load Balancing – Refer to the Elastic Load Balancing documentation
• Amazon CloudFront – Refer to the CloudFront documentation
• Amazon API Gateway – Refer to the API Gateway documentation
• AWS Elastic Beanstalk – Refer to the AWS Elastic Beanstalk documentation
• AWS CloudFormation – Support is currently limited to public certificates that use email validation. Refer to the AWS CloudFormation documentation
In addition, you can use private certificates issued with ACM Private CA with EC2 instances, containers, IoT devices, and on your own servers.
Alternatively, you can use Let's Encrypt, a service provided by EFF, for free. They have a tool called CertBot to automatically renew the certificates for you.

I'm new to AWS and hoping someone can answer my question here. I've created a web server on an EC2 instance and installed Craft CMS on it. I've requested a public certificate from Certificate Manager, and put the CNAME in the route53 hosted zone for the domain name. The certificate is attached to the Load balancer I attached to my EC2 instance. If I set up cloudfront with all this my website is still showing up as insecure (meaning I'm not doing something right). How should I go about connecting cloudfront to my EC2 instance? With or without the load balancer. I only have one instance running so I don't really need the load balancer either. Thanks!
Just to clarify what you are trying to accomplish: 1) You have one or more EC2 instances, presumably in an auto-scaling group; 2) Those EC2 instances are set as targets for your ELB; 3) You have a certificate that is valid for your ELB hostname, let's call it elb.mydomain.com.
And now you are trying to setup CloudFront with the ELB as the origin?
Starting with the CloudFront certificate: Is the certificate also valid for your CloudFront hostname (let's call it www.mydomain.com)? If not, you will need to create and validate another cert for www.mydomain.com.
Second, the CloudFront distribution must be configured to use a certificate that is valid for the hostname you want to use. You must also include the hostname as an alternate domain name in the CloudFront distribution. Then make sure your route53 CNAME entry points from your desired hostname to the CloudFront distribution, which will be something like d18sdfijsilj.cloudfront.net.
I am running a Spring Boot Application (as a RESTful Webservice) dockerized in an EC2 Instance. If I start the container, everything is working fine, but only with HTTP. e.g. http://ec2-54-93-55.eu-central...com
I already tried setting up the Security Groups of my EC2 Instance, where I enabled HTTPS, but it still does not work.
Now I want to add a SSL Certificate to my Instance with the AWS Certificate Manager. The problem is now, that I need a hosted domain for this and I can not use the Domain of my EC2 Instance.
I tried setting it up as api.mydomain.com and it is verified now. How can I now connect my EC2 Instance with this domain?
I tried creating an Alias in Route 53 by routing api.mydomain.com to the EC2 public DNS. But this did not work too.
You will not be able to attach an ACM public certificate to your EC2 instance as they are required to be attached to either one of these resources:
CloudFront
Elastic Load Balancer.
Once these are configured you will need to update the DNS record on your hosting provider to target the CNAME of whichever of these resources they use.
If you were using Route 53 as your hosting provider you would add your record to the public hosted zone for that domain, however this process is slightly different for each DNS provider.
So far i did below configuration.
I hosted my site on EC2 AWS machine. Public ip and public DNS.
I can access my website by ip as well as public DNS.
I purchased domain name from GoDaddy. www.xxtrasc.com
On AWS I created Hosted Zone then map www.app.xxtrasc.com successfully.
Now i access my website directly www.app.xxtrasc.com
Next want to enable https
On AWS Certificate Manager order certificate with domain name *.xxtrasc.com
Did everything to add CNAME and all. I can see status gree colored Issued on ACM.
Now how i can attached this certificate to my web site so that i can access https://www.app.xxtrasc.com
You cannot use ACM to directly install your ACM Certificate on your AWS based website or application
https://docs.aws.amazon.com/acm/latest/userguide/gs-acm-install.html
You must use one of the following services:
Elastic Load Balancing
Amazon CloudFront
AWS Elastic Beanstalk
Amazon API Gateway
AWS CloudFormation
Please read the official doc : https://docs.aws.amazon.com/acm/latest/userguide/acm-services.html
So to install the certificate directly under apache2/nginx configuration you need to obtain the certificate from other third parties like Lets Encrypt, GoDaddy etc. you can read about that here - https://in.godaddy.com/help/manually-install-an-ssl-certificate-on-my-apache-server-centos-5238
On AWS I recommend using an ELB an placing your EC2 instances behind this ELB. This will allow you to select your ACM certificate from ELB itslef. Please read following doc to use classic load balancer with HTTPS https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/ssl-server-cert.html
If you want to enable SSL on your site, you need to purchase SSL certificate. You can purchase it with Godaddy and then setup it on AWS server. Without SSL certificate, your https site won't work.
I set up EC2 Ubuntu instance, assigned an elastic IP, got example.com (domain) to the ec2 instance via Route53. Added an SSL certificate using ACM (certificate manager) which says 'issued'.
However, https://example.com raises ERR_SSL_PROTOCL_ERROR. http://example.com is working.
The security group has HTTPS port open.
What's wrong here? Why this is not working? Any clues? curl https://localhost -k shows local port 443 refused.
You can't deploy a public ACM certificate directly to an instance. The "issued" state, just means it's ready to be applied somewhere. It needs to be applied to a service that supports ACM like an ELB, API Gateway, or a CloudFront distribution, which can be used to offload SSL processing. See the faqs for an overview of how they can be used.
For a certificate directly on the instance, you can use letsencrypt to issue free, trusted certs.
Also, this assumes that you've configured the web server to listen on 443.
ACM can only be used with AWS resources such as Elastic Load Balancer, Amazon CloudFront distributions and APIs on Amazon API Gateway.
Make sure that you are using one the above services to serve your website content.
ACM cannot be directly used with EC2 instance, you either need Elastic Load Balancer or CloudFront distribution to used it.
AWS has come up with a new service AWS Certificate Manager. One thing I got from the description is that if we are using this service we don't have to pay for the certificate anymore.
They are providing certificates for Elastic Load Balancer (ELB) and CloudFront, but I didn't find EC2 anywhere.
Is there any way to use the certificate with EC2?
Q: Can I use certificates on Amazon EC2 instances or on my own servers?
No. At this time, certificates provided by ACM can only be used with specific AWS services.
Q: With which AWS services can I use certificates provided by ACM?
You can use ACM with the following AWS services:
• Elastic Load Balancing
• Amazon CloudFront
• AWS Elastic Beanstalk
• Amazon API Gateway
https://aws.amazon.com/certificate-manager/faqs/
You can't install the certificates created by Amazon Certificate Manager (ACM) on resources you have direct low-level access to, like EC2 or servers outside of AWS, because you aren't provided with access to the private keys. These certs can only be deployed on resources managed by the AWS infrastructure -- ELB and CloudFront -- because the AWS infrastructure holds the only copies of the private keys for the certificates that it generates, and maintains them under tight security with auditable internal access controls.
You'd have to have your EC2 machines listening behind CloudFront or ELB (or both, cascaded, would also work) in order to use these certs for content coming from EC2... because you can't install these certs directly on EC2 machines.
No, you cannot use aws certificate manager for deploying certs on EC2. The certificate manager certs can only be deployed against cloudfront and elastic load balancer. Inoredr to use it on ec2, you need to put elb on top of ec2, so that request from client to load balancer will be https protected and from elb to ec2 webserver will be on http.
If you are using AWS ACM Cert for internal purpose only then you could probably use AWS ACM Private CA to issue the certs.(I think you can use it for public/external traffic purpose as well if your root CA is publicly trusted CA).
https://docs.aws.amazon.com/acm-pca/latest/userguide/PcaGetStarted.html
During Application/EC2/Container startup, set a step to export your ACM Private CA issued Cert/Private Key to your destination and start referring that for serving the traffic.
https://docs.aws.amazon.com/cli/latest/reference/acm/export-certificate.html
One good thing is, you can control who can call export cert feature using IAM Role so not everyone can download private key of the cert.
One downside with this is, private CA is expensive AWS service($400/month).

Adding to the comments above, you can't use the AWS Certificate Manager for this, but you can add a Let's Encrypt certificate to ec2 on a Windows server running IIS and it's pretty easy:
Associate an elastic ip with your ec2 instance.
Make sure you have a registered domain. You can't use ec2----------.us-east-1.compute.amazonaws.com type names that come with your instance.
Through your domain provider's DNS settings have your domain point to your Elastic IP.
Connect to your ec2 instance and add your domain name to the site bindings.
Go to https://github.com/PKISharp/win-acme/releases
Look under assets, and use the latest version (win-acme.v2.0.10.444.zip for example). This is the only assets folder that you need.
Unzip the folder, open the terminal as administrator, and cd into the unzipped folder.
Run wacs.exe and follow the prompts.
Make sure the security group assigned to your instance allows traffic (at the very least your own IP) through the HTTPS port you chose in IIS; this is port 443 by default.
I found the links below helpful when I was figuring this out. Here is a video using an earlier release if you need more help, but it's the same idea.
