MySQL Error 3185: Keyring Master Key Missing
Description
This error indicates that MySQL is unable to locate the necessary master key within its configured keyring. This typically occurs when the server attempts to access encrypted data (e.g., for Transparent Data Encryption - TDE) but the keyring plugin is not loaded, incorrectly configured, or the keyring itself is uninitialized or inaccessible.
Error Message
Can't find master key from keyring, please check in the server log if a keyring is loaded and initialized successfully.
Known Causes
4 known causesKeyring Plugin Not Loaded
The required keyring plugin (e.g., `keyring_file`, `keyring_encrypted_file`, `keyring_aws`) is not correctly loaded or enabled in the MySQL server configuration.
Incorrect Keyring Path
The configuration parameter for the keyring data file or store (e.g., `keyring_file_data`) points to an incorrect, non-existent, or inaccessible location.
Uninitialized or Corrupt Keyring
The keyring store may be newly configured and has not yet been initialized with a master key, or the existing keyring data file has become corrupted.
Insufficient File Permissions
The MySQL server process lacks the necessary read and/or write permissions for the keyring data file or its containing directory.
