Generate your CSR:

openssl req -new -newkey rsa:3072 -nodes  -keyout host.domain.com.2021.key -out host.domain.com.2021.csr

When you receive the certificate, you may also receive intermediate cert(s) from the vendor.  Depending upon the application, the certs may have to be concatenated together and the configuration updated.

I identify my certs by year so that I can easily roll back using the configuration file(s).
