MySQL Error 3807: Binary Log Keyring Failure
Description
This error indicates that MySQL failed to manage or rotate the binary log master key, which is used for encrypting binary and relay log files. It typically occurs when attempting a key rotation operation, but the server cannot interact with the configured keyring component, leaving the old key in use.
Error Message
Failed to operate binary log master key on keyring, please check if keyring is loaded. The statement had no effect: the old binary log master key is still in use, the keyring, binary and relay log files are unchanged, and the server could not start using a new binary log master key for encrypting new binary and relay log files.
Known Causes
4 known causesKeyring Plugin Not Loaded
The MySQL server's configured keyring plugin, responsible for managing encryption keys, is not loaded or properly initialized during startup.
Incorrect Keyring Configuration
The `my.cnf` or `my.ini` file contains incorrect paths or parameters for the keyring plugin, preventing it from functioning correctly.
File System Permissions
The MySQL server process lacks the necessary read/write permissions for the keyring data files or the plugin shared library.
Corrupted or Missing Keyring File
The underlying keyring data file (e.g., `keyring_file_data.dat` for `keyring_file`) is corrupted, inaccessible, or has been deleted.
