--component-dir=dir_name

The directory where keyring components are located. This is typically the value of the plugin_dir system variable for the local MySQL server.

--defaults-extra-file=file_name

Read this option file after the global option file but (on Unix) before the user option file. If the file does not exist or is otherwise inaccessible, an error occurs. If file_name is not an absolute path name, it is interpreted relative to the current directory.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--defaults-file=file_name

Use only the given option file. If the file does not exist or is otherwise inaccessible, an error occurs. If file_name is not an absolute path name, it is interpreted relative to the current directory.

Exception: Even with --defaults-file, client programs read .mylogin.cnf.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--defaults-group-suffix=str

Read not only the usual option groups, but also groups with the usual names and a suffix of str. For example, mysql_migrate_keyring normally reads the [mysql_migrate_keyring] group. If this option is given as --defaults-group-suffix=_other, mysql_migrate_keyring also reads the [mysql_migrate_keyring_other] group.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--destination-keyring=name

The destination keyring component for key migration. The format and interpretation of the option value is the same as described for the --source-keyring option.

--destination-keyring-configuration-dir=dir_name

This option applies only if the destination keyring component global configuration file contains "read_local_config": true, indicating that component configuration is contained in the local configuration file. The option value specifies the directory containing that local file.

--get-server-public-key

Request from the server the public key required for RSA key pair-based password exchange. This option applies to clients that authenticate with the caching_sha2_password authentication plugin. For that plugin, the server does not send the public key unless requested. This option is ignored for accounts that do not authenticate with that plugin. 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 information about the caching_sha2_password plugin, see Section 8.4.1.2, “Caching SHA-2 Pluggable Authentication”.

--host=host_name, -h host_name

The host location of the running server that is currently using one of the key migration keystores. Migration always occurs on the local host, so the option always specifies a value for connecting to a local server, such as localhost, 127.0.0.1, ::1, or the local host IP address or host name.

--login-path=name

Read options from the named login path in the .mylogin.cnf login path file. A “login path” is an option group containing options that specify which MySQL server to connect to and which account to authenticate as. To create or modify a login path file, use the mysql_config_editor utility. See Section 6.6.7, “mysql_config_editor — MySQL Configuration Utility”.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--no-defaults

Do not read any option files. If program startup fails due to reading unknown options from an option file, --no-defaults can be used to prevent them from being read.

The exception is that the .mylogin.cnf file is read in all cases, if it exists. This permits passwords to be specified in a safer way than on the command line even when --no-defaults is used. To create .mylogin.cnf, use the mysql_config_editor utility. See Section 6.6.7, “mysql_config_editor — MySQL Configuration Utility”.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--online-migration

This option is mandatory when a running server is using the keyring. It tells mysql_migrate_keyring to perform an online key migration. The option has these effects:

--password[=password], -p[password]

The password of the MySQL account used for connecting to the running server that is currently using one of the key migration keystores. The password value is optional. If not given, mysql_migrate_keyring prompts for one. If given, there must be no space between --password= or -p 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. To avoid giving the password on the command line, use an option file. See Section 8.1.2.1, “End-User Guidelines for Password Security”.

To explicitly specify that there is no password and that mysql_migrate_keyring should not prompt for one, use the --skip-password option.

--port=port_num, -P port_num

For TCP/IP connections, the port number for connecting to the running server that is currently using one of the key migration keystores.

--print-defaults

Print the program name and all options that it gets from option files.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--server-public-key-path=file_name

The path name to a file in PEM format containing a client-side copy of the public key required by the server for RSA key pair-based password exchange. This option applies to clients that authenticate with 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 8.4.1.3, “SHA-256 Pluggable Authentication”, and Section 8.4.1.2, “Caching SHA-2 Pluggable Authentication”.

--socket=path, -S path

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.

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.

--source-keyring=name

The source keyring component for key migration. This is the component library file name specified without any platform-specific extension such as .so or .dll. For example, to use the component for which the library file is component_keyring_file.so, specify the option as --source-keyring=component_keyring_file.

--source-keyring-configuration-dir=dir_name

This option applies only if the source keyring component global configuration file contains "read_local_config": true, indicating that component configuration is contained in the local configuration file. The option value specifies the directory containing that local file.

--ssl*

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-fips-mode={OFF|ON|STRICT}

Controls whether to enable FIPS mode on the client side. The --ssl-fips-mode option differs from other --ssl-xxx options in that it is not used to establish encrypted connections, but rather to affect which cryptographic operations to permit. See Section 8.8, “FIPS Support”.

These --ssl-fips-mode values are permitted:

As of MySQL 8.0.34, this option is deprecated. Expect it to be removed in a future version of MySQL.

--tls-ciphersuites=ciphersuite_list

The permissible ciphersuites for encrypted connections that use TLSv1.3. The value is a list of one or more colon-separated ciphersuite names. The ciphersuites that can be named for this option depend on the SSL library used to compile MySQL. For details, see Section 8.3.2, “Encrypted Connection TLS Protocols and Ciphers”.

--tls-version=protocol_list

The permissible TLS protocols for encrypted connections. The value is a list of one or more comma-separated protocol names. The protocols that can be named for this option depend on the SSL library used to compile MySQL. For details, see Section 8.3.2, “Encrypted Connection TLS Protocols and Ciphers”.

--user=user_name, -u user_name

The user name of the MySQL account used for connecting to the running server that is currently using one of the key migration keystores.

--verbose, -v

Verbose mode. Produce more output about what the program does.

--version, -V

Display version information and exit.
