MySQL Error 3785: Missing Keyring Encryption Key
Description
This error indicates that MySQL cannot locate or access a required encryption key within its configured keyring. This typically occurs when the server attempts an operation (e.g., replication) that relies on a key that is either not loaded, misconfigured, or inaccessible. The server log often contains further details about the keyring's status.
Error Message
Can't find 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 or Initialized
The MySQL server failed to load or properly initialize the configured keyring plugin, making all stored encryption keys unavailable.
Missing or Corrupted Keyring File
The physical file storing the encryption keys is either missing from its expected location or has become corrupted, preventing key retrieval.
Incorrect Keyring Configuration Path
The `keyring_file_data` or other keyring-related configuration parameters point to an incorrect or non-existent file path in `my.cnf`.
Insufficient File System Permissions
The MySQL server process lacks the necessary read permissions to access the keyring file or its containing directory.
