       mysql_secure_installation - improve MySQL installation security


       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 2.10.4, "Securing the Initial
       MySQL Accounts".

       As of MySQL 5.7.2, mysql_secure_installation is an executable binary
       available on all platforms. Before 5.7.2, it was a script available for
       Unix and Unix-like systems.

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

           shell> mysql_secure_installation

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

       As of MySQL 5.7.2, mysql_secure_installation supports these additional

       o   The validate_password plugin 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.

       o   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

               shell> 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 5.2.6, "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.  file_name is interpreted
           relative to the current directory if given as a relative path name
           rather than a full path name.

       o   --defaults-file=file_name

           Use only the given option file. If the file does not exist or is
           otherwise inaccessible, an error occurs.  file_name is interpreted
           relative to the current directory if given as a relative path name
           rather than a full path name.

       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 the
           --defaults-group-suffix=_other option is given,
           mysql_secure_installation also reads the [client_other] and
           [mysql_secure_installation_other] groups.

       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, if it exists, is read
           in all cases. This permits passwords to be specified in a safer way
           than on the command line even when --no-defaults is used.
           (.mylogin.cnf is created by the mysql_config_editor utility. See

       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

       o   --port=port_num, -P port_num

           The TCP/IP port number to use for the connection.

       o   --print-defaults

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

       o   --protocol={TCP|SOCKET|PIPE|MEMORY}

           The connection protocol to use for connecting to the server. It is
           useful when the other connection parameters normally would cause a
           protocol to be used other than the one you want. For details on the
           permissible values, see Section 5.2.2, "Connecting to the MySQL

       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.

       o   --ssl*

           Options that begin with --ssl specify whether to connect to the
           server using SSL and indicate where to find SSL keys and
           certificates. See Section 7.4.5, "Command Options for Secure

       o   --tls-version=protocol_list

           The protocols permitted by the client for encrypted connections.
           The value is a comma-separated list containing one or more protocol
           names. The protocols that can be named for this option depend on
           the SSL library used to compile MySQL. For details, see
           Section 7.4.3, "Secure Connection Protocols and Ciphers".

           This option was added in MySQL 5.7.10.

       o   --use-default

           Execute noninteractively. This option can be used for unattended
           installation operations. This option was added in MySQL 5.7.4.

       o   --user=user_name, -u user_name

           The MySQL user name to use when connecting to the server.
