How Do I Check the Validity Period of the SSL Certificate of My RDS for MySQL Instance?

When you connect to an RDS for MySQL DB instance using an SSL connection, run the following command to check whether the certificate has expired:

show status like '%ssl_server%';

Update the root certificate to the latest version before it expires:

1. On the Overview page of the DB instance, click Download under SSL to download the new root certificate or certificate bundle.
2. Reboot the DB instance for the new certificate to take effect.
3. Connect to the DB instance using the new certificate or certificate bundle.
   • Connecting to a DB Instance Through a Private Network
   • Connecting to a DB Instance Through a Public Network
   

   If a certificate is about to expire, replace it with an officially issued certificate to improve system security.
