mysqlcheck — A Table Maintenance Program the  sha256_password  or  caching_sha2_password  authentication plugin. This option is ignored for accounts that do not authenticate with one of those plugins. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection. If  --server-public-key-path= file_name  is given and specifies a valid public key file, it takes precedence over  --get-server-public-key . For  sha256_password , this option applies only if MySQL was built using OpenSSL. For information about the  sha256_password  and  caching_sha2_password  plugins, see Section 6.4.1.3, “SHA-256 Pluggable Authentication” , and Section 6.4.1.2, “Caching SHA-2 Pluggable Authentication” . On Windows, the shared-memory name to use for connections made using shared memory to a local server. The default value is  MYSQL . The shared-memory name is case-sensitive.

On Windows, this option applies only if the server was started with the  named_pipe  system variable enabled to support named-pipe connections. In addition, the user making the connection must be a member of the Windows group specified by the  named_pipe_full_access_group  system variable. Options that begin with  --ssl  specify whether to connect to the server using encryption and indicate where to find SSL keys and certificates. See Command Options for Encrypted Connections. • --ssl* • --socket= path ,  -S  path • --skip-database= db_name • --silent ,  -s • --shared-memory-base-name= name 470
