Install SSL certificate

Hey guys,

I have a setup of a couple servers on Digital Ocean installed using Forge. The main domain is added on a server, a couple of specific subdomains on another server, while the rest of the subdomains (dynamically) are loaded on the third server.

What I'm trying to do, is to get a single wildcard SSL certificate on all servers, used for all subdomains. I want to buy a rapid SSL certificate, but I'm not sure about all the steps I need to do.

Should I make a new CSR from the www.domain.com forge server and use it to issue the wildcard certificate? Do I need to issue the CSR or the certificate for www.domain.com or for domain.com? After I get the certificate, I understand that I need to concatenate the server certificate and the intermediate certificate.

I know that Forge also provides a clone certificate feature, so I think that I'm going to use it for cloning this certificate on the rest of the servers.

I hope you can confirm or guide me on this.

Thanks!
