NAME
       mysql_secure_installation - improve MySQL installation security

SYNOPSIS
       mysql_secure_installation

DESCRIPTION
       This program enables you to improve the security of your MySQL
       installation in the following ways:

       o   You can set a password for root accounts.

       o   You can remove root accounts that are accessible from outside the
           local host.

       o   You can remove anonymous-user accounts.

       o   You can remove the test database (which by default can be accessed
           by all users, even anonymous users), and privileges that permit
           anyone to access databases with names that start with test_.

       mysql_secure_installation helps you implement security recommendations
       similar to those described at Section 2.9.4, "Securing the Initial
       MySQL Account".

       Normal usage is to connect to the local MySQL server; invoke
       mysql_secure_installation without arguments:

           mysql_secure_installation

       When executed, mysql_secure_installation prompts you to determine which
       actions to perform.

       The validate_password component can be used for password strength
       checking. If the plugin is not installed, mysql_secure_installation
       prompts the user whether to install it. Any passwords entered later are
       checked using the plugin if it is enabled.

       Most of the usual MySQL client options such as --host and --port can be
       used on the command line and in option files. For example, to connect
       to the local server over IPv6 using port 3307, use this command:

           mysql_secure_installation --host=::1 --port=3307

       mysql_secure_installation supports the following options, which can be
       specified on the command line or in the [mysql_secure_installation] and
       [client] groups of an option file. For information about option files
       used by MySQL programs, see Section 4.2.2.2, "Using Option Files".

       o   --help, -?  Display a help message and exit.

       o   --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 4.2.2.3, "Command-Line Options that Affect
           Option-File Handling".

       o   --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.

           For additional information about this and other option-file
           options, see Section 4.2.2.3, "Command-Line Options that Affect
           Option-File Handling".

       o   --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_secure_installation normally reads the [client] and
           [mysql_secure_installation] groups. If this option is given as
           --defaults-group-suffix=_other, mysql_secure_installation also
           reads the [client_other] and [mysql_secure_installation_other]
           groups.

           For additional information about this and other option-file
           options, see Section 4.2.2.3, "Command-Line Options that Affect
           Option-File Handling".

       o   --host=host_name, -h host_name Connect to the MySQL server on the
           given host.

       o   --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
           mysql_config_editor(1).

           For additional information about this and other option-file
           options, see Section 4.2.2.3, "Command-Line Options that Affect
           Option-File Handling".

       o   --password=password, -p password This option is accepted but
           ignored. Whether or not this option is used,
           mysql_secure_installation always prompts the user for a password.

       o   --port=port_num, -P port_num For TCP/IP connections, the port
           number to use.

       o   --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 4.2.2.3, "Command-Line Options that Affect
           Option-File Handling".

       o   --protocol={TCP|SOCKET|PIPE|MEMORY} The transport protocol to use
           for connecting to the server. It is useful when the other
           connection parameters normally result in use of a protocol other
           than the one you want. For details on the permissible values, see
           Section 4.2.7, "Connection Transport Protocols".

       o   --socket=path, -S path For connections to localhost, the Unix
           socket file to use, or, on Windows, the name of the named pipe to
           use.

           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 connection must be a member of the
           Windows group specified by the named_pipe_full_access_group system
           variable.

       o   --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 the section called "Command Options for Encrypted
           Connections".

       o   --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 6.8, "FIPS Support".

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

           o   OFF: Disable FIPS mode.

           o   ON: Enable FIPS mode.

           o   STRICT: Enable "strict" FIPS mode.

               Note
               If the OpenSSL FIPS Object Module is not available, the only
               permitted value for --ssl-fips-mode is OFF. In this case,
               setting --ssl-fips-mode to ON or STRICT causes the client to
               produce a warning at startup and to operate in non-FIPS mode.
           As of MySQL 8.0.34, this option is deprecated. Expect it to be
           removed in a future version of MySQL.

       o   --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 6.3.2, "Encrypted
           Connection TLS Protocols and Ciphers".

           This option was added in MySQL 8.0.16.

       o   --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 6.3.2, "Encrypted Connection TLS Protocols and
           Ciphers".

       o   --use-default Execute noninteractively. This option can be used for
           unattended installation operations.

       o   --user=user_name, -u user_name The user name of the MySQL account
           to use for connecting to the server.
