MySQL Error 3794: Binlog Key Recovery Failure
Description
This error indicates that MySQL is unable to retrieve the master key required to decrypt the binary log (binlog). It typically occurs during server startup or recovery operations when binlog encryption is enabled, pointing to an issue with the keyring component responsible for key management.
Error Message
Unable to recover binlog encryption master key, please check if keyring is loaded.
Known Causes
4 known causesKeyring Module Not Loaded
The configured keyring component, essential for managing encryption keys, failed to load during MySQL server startup.
Incorrect Keyring Configuration
The MySQL configuration file (`my.cnf`) contains incorrect paths or settings for the keyring plugin, preventing its proper initialization.
Missing or Corrupt Keyring File
The physical file storing the encryption keys (e.g., `keyring_file.key`) is either missing, inaccessible, or has become corrupted.
Keyring File Permissions
The MySQL server process lacks the necessary file system permissions to read or write to the keyring data file or its directory.
