MySQL Database System                             MYSQL_SECURE_INSTALLATION(1)



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:

       ·   You can set a password for root accounts.

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

       ·   You can remove anonymous-user accounts.

       ·   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 Account”.

       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.

       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:

           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 4.2.2.2, “Using Option Files”.

       ·   --help, -?

           Display a help message and exit.

       ·   --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.

           For additional information about this and other option-file
           options, see Section 4.2.2.3, “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.  file_name is interpreted
           relative to the current directory if given as a relative path name
           rather than a full path name.

           For additional information about this and other option-file
           options, see Section 4.2.2.3, “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_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.

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

       ·   --host=host_name, -h host_name

           Connect to the MySQL server on the given host.

       ·   --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
           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”.

       ·   --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.

       ·   --port=port_num, -P port_num

           For TCP/IP connections, the port number to use.

       ·   --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”.

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

           The connection 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 4.2.4, “Connecting to the MySQL
           Server Using Command Options”.

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

       ·   --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 the section called “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 are permitted. See Section 6.5, “FIPS Support”.

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

           ·   OFF: Disable FIPS mode.

           ·   ON: Enable FIPS mode.

           ·   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.

       ·   --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.

       ·   --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”.

       ·   --use-default

           Execute noninteractively. This option can be used for unattended
           installation operations.

       ·   --user=user_name, -u user_name

           The user name of the MySQL account to use for connecting to the
           server.
