Configuring a CCM Private Certificate

Scenarios

GeminiDB Influx allows you to use the certificate issued by Cloud Certificate Management Service (CCM) to connect to your DB instance. You can select a CCM certificate when you create an instance or update its certificate after the instance is created.

This section describes how to apply for a CCM private certificate to a DB instance in either of the following ways:

1. Select a certificate when you create an instance.
2. Update the certificate after the instance is created.

Precautions

The instance status is Available.

Prerequisites

You have created a CCM private certificate. If there are no CCM private certificates, you can apply for a private certificate by referring to Applying for a Private Certificate in the Cloud Certificate Manager User Guide.

• When you apply for a private certificate, specify the IP address of the instance that you want to access for Configure Certificate AltName. If this parameter is not specified, the database connection will fail.
  • If you choose to enable SSL when you create an instance, you can only add an EIP in the Configure Certificate AltName area. This is because the instance has not been created, the system has not generated a private IP address for it.
  • When you update the certificate after an instance is created, you can add private IP addresses or EIPs of all the instance nodes at the Configure Certificate AltName area.

   • The new certificate takes effect only after the instance is restarted. Perform this operation during off-peak hours to minimize impacts on your services.
   • The certificate cannot be changed to the default SSL certificate.

6. After the certificate is updated, check whether the certificate status is Available on the Basic Information page.
