AWS EC2 UCC SSL Certificate

Help
1

I have an AWS EC2 instance running on public IP where two different domain websites are being setup.

My domain are : tattvadesigns.co.in and zestatech.com

My web server is (include version): Apache 2.4.39

The operating system my web server runs on is (include version): Windows Server 2012 R2

My hosting provider, if applicable, is: AWS

I can login to a root shell on my machine (yes or no, or I don’t know): YES, through RDP I login into the Virtual Machine.

I am using latest Wamserver with Virtual Host and Wordpress to setup two websites - one for tattvadesigsn.co.in and another for zestatech.com .

For SSL I need a certificate but I understand that I cannot get certificate for IP but for domain. Since I have two domains, I understand I have to get a UCC SSL certificate. Please help me with the process. I have downloaded win-acme.

Hi @shashank4897,

Welcome to the community forums.

Have you checked out any of the Windows clients listed on https://letsencrypt.org/docs/client-options/ ? While you experiment, I recommend using the staging environment so that you avoid hitting rate limits.

You don’t necessarily need to get a UCC certificate. Instead, you can issue a certificate for both www.example.com and example.com and another certificate for both www.example.org and example.org.

Thanks Phil…The client I am planning to use is in the list - win-acme.What I want to know is can a single certificate work for two different domains - tattvadesigns.co.in and zestatech. I have been searching on the Internet and trying to find that if I take a certificate with one domain - say tattvadesigns,co.in , can apache be configured to take the ssl request for the second domain - zestatech.com

Hi @shashank4897

yes, it's possible. You can create one certificate with a lot of domain names and use the same certificate with different vHosts.

But maybe it's not the best solution.

Windows 2012 supports SNI, so you can create different Webservers with different bindings, every binding uses an own certificate.

Hi Juergen...Thanks for the guidance.

I tried creating a certificate for domain tattvadesigns.co.in using win-acme client...I am posting the entire command and response...It gives authorisation error ... The webserver is Apache 2.4.39 on Windows 2012 R2 Server on AWS running Wamp 3.0 with Wordpress.
I checked on the browser to access a file using http://ipaddress/tattvadesigns/ , I am able to browse but with the command
http://tattvadesigns.co.in/ it shows the website home page. The domain tattvadesigns.com has been redirect URL to http://ipaddress/tattvadesigns.

That can't work. There is not your website, there is a frame with your website ( https://check-your-website.server-daten.de/?q=tattvadesigns.co.in ):

Your ip address:

Host T IP-Address is auth. ∑ Queries ∑ Timeout
tattvadesigns.co.in A 184.168.131.241
Scottsdale/Arizona/US yes 2 0
AAAA yes
www.tattvadesigns.co.in C tattvadesigns.co.in yes 1 0
A 184.168.131.241
Scottsdale/Arizona/US yes

The frame:

<frame src="[http://13.233.201.28/tattvadesigns](view-source:http://13.233.201.28/tattvadesigns)" frameborder="0" />

Your DNS A entry must go directly to your 13.233.201.28.

And connecting this ip address with the correct host header must work - https://check-your-website.server-daten.de/?q=13.233.201.28&h=tattvadesigns.co.in

Result: Your /.well-known/acme-challenge sends a http status 200 checking a not existing file:

There is a http status 404 - Not Found expected.

You can't create a certificate via http-01 validation if you use such a "frame redirect". And a certificate would not work, if you use src="ip-address".
