Root CA CAs are generally grouped by organization, that is, ORG1,ORG2,ORG3 have their own CAs. When the CA is started, two environment variables, fabric_ca_server_ca_certfile and Fabric_ca_server_ca_keyfile, are set. What happens if you don't set these two up? In fact, if not set, the CA server will generate these two files on its own according to the default CA CONFIG.
