Nginx / Comodo PositiveSSL / CentOS 7

Standard

1. Before you purchase your SSL

Before any purchase of an SSL you’ll need a key file and a csr (Certificate Signing Request).

The certificate registrar is going to ask for the contents of your csr file, just cut and paste whats inside the file into the webform. Make sure you register with the domain name you plan on using. Purchase your SSL, they’ll send your administrator an email validate that. Then wait for an email from Comodo with a zip file.

Within this zip file you’ll receive 4 files:

  • AddTrustExternalCARoot.crt – Root Cert
  • COMODORSAAddTrustCA.crt – Intermediate Cert
  • COMODORSADomainValidationSecureServerCA.crt – Intermediate Cert
  • server_name.crt – Your Positive Cert
