Different certificate for same domain at once


#1

Hi,
I have no trouble to generate and use Let’s Encrypt certificate, but just want to ask, if it is possible to generate different certificate for same domain. The reason for this is that different services is using different servers, but the same gateway. So when I generate the certificate on one server, I need to copy it on others servers as well. Would it be possible to generate the different certificate for different servers while using same domain name?

And if yes, is there some limitation or restriction I should consider?

Thanks

The operating system my web server runs on is (include version): Linux

I can login to a root shell on my machine (yes or no, or I don’t know): yes

Hi @readyblue

yes, this is possible. If you have 30 servers with the same domain name, you can

  • create one certificate with 30 names and copy it
  • create 30 certificates with 1 name, from one server and copy it
  • create 30 certificates with 1 name, from 30 servers - no copy required

There are two rate limits:

Certificates per Registered Domain , (50 per week)

and

Duplicate Certificate limit of 5 certificates per week

But if you have a working configuration with 200 servers, you can slowly create the new certificates and move. The second limit shouldn’t be a problem. To test, you can use the stage system. It has his own and higher limits.
