confidential
I have a domain with about 10 A records pointed to different subdomains. I have a Cloudflare Origin Certificate currently installed on just 1 of the webservers. Can/should I install this same origin cert on all the different machines? Will installing this on any machine affect any of the others?
The certificate is hostname-specific. You can install it on many servers, serving the specified hostnames, as you wish.
Since I initially generated the Cloudflare Origin cert based on a certificate signing request (CSR) from the 1st server I used it on, lets say ServerA.mycompany.com, can I just download the existing origin cert and install on ServerB.mycompany.com? Do I not need to do anything with a certificate request?
You can’t download the certificate (or better private key) any more, but you can use the one you already have.
So I don’t need to create a certificate signing request from every server I want to install the Origin Certificate on? I can just download the existing origin cert from Cloudflare that I generated from the original CSR on server A and use that on any server?
As mentioned, certificates are specific to the hostnames they were issued for, not servers.
