Installing SSL certificate files onto multiple servers can be accomplished using either of the two methods outlined in this article. Sharing certificates between servers is a free function of your certificate at SSL.com. You may rekey a certificate as many times as needed at no extra charge to you.
Sharing Certificates via PFX
The first method involves creating a .pfx file (also sometimes called a PKCS#12 file) of your certificate, intermediates, and private key and importing that .pfx onto one or more other servers. Often, cloud providers like Azure require that you to create a .pfx file to use their service.
Share Unique Certificate
The alternative method is more secure but also a bit more time consuming in terms of certificate management. If you would like to use a different Private Key for each server, you’ll want to follow the steps outlined below:
- Generate your CSR/Private Key pair on the desired server (Apache, NGINX, IIS, WHM/cPanel)
- Reprocess your certificate order with the new CSR.
- Configure the server to use the newly issued certificate files. (Apache, NGINX, Windows, WHM/cPanel)
