The MySQL Keyring The password of the MySQL account used for connecting to the running server that is currently using one of the key migration keystores. See Section 6.4.4.13, “Migrating Keys Between Keyring Keystores” . The password value is optional. If not given, the server prompts for one. If given, there must be  no space between  --keyring-migration-password=  and the password following it. If no password option is specified, the default is to send no password. Specifying a password on the command line should be considered insecure. See Section 6.1.2.1, “End- User Guidelines for Password Security” . You can use an option file to avoid giving the password on the command line. In this case, the file should have a restrictive mode and be accessible only to the account used to run the migration server. Command-Line Format --keyring-migration-port=port_num Type Numeric Default Value 3306 Command-Line Format --keyring-migration- socket={file_name|pipe_name} Type String Command-Line Format --keyring-migration- source=plugin_name Type String 1448 Note --keyring-migration-source  and  --keyring-migration- destination  are mandatory for all keyring migration operations. The source and destination plugins must differ, and the migration server must support both plugins. The option value is similar to that for  --plugin-load , except that only one plugin library can be specified. The value is given as  plugin_library  or  name = plugin_library , where plugin_library  is the name of a library file that contains plugin code, and  name  is the name of a plugin to load. If a plugin library is named without any preceding plugin name, the server loads all plugins in the library. With a preceding plugin name, the server loads only the named plugin from the libary. The server looks for plugin library files in the directory named by the  plugin_dir  system variable. The source keyring plugin for key migration. See Section 6.4.4.13, “Migrating Keys Between Keyring Keystores” . For Unix socket file or Windows named pipe connections, the socket file or named pipe for connecting to the running server that is currently using one of the key migration keystores. See Section 6.4.4.13, “Migrating Keys Between Keyring Keystores” . For TCP/IP connections, the port number for connecting to the running server that is currently using one of the key migration keystores. See Section 6.4.4.13, “Migrating Keys Between Keyring Keystores” . • --keyring-migration-source= plugin • --keyring-migration-socket= path • --keyring-migration-port= port_num
