MYSQL_INSTALL_DB(1)                   MySQL Database System                   MYSQL_INSTALL_DB(1)

       mysql_install_db - initialize MySQL data directory

       mysql_install_db [options]

       mysql_install_db initializes the MySQL data directory and creates the system tables that
       it contains, if they do not exist.  mysql_install_db is a shell script and is available
       only on Unix platforms. (As of MySQL 5.6, mysql_install_db is a Perl script and can be
       used on any system with Perl installed.)

       To invoke mysql_install_db, use the following syntax:

           shell> mysql_install_db [options]

       Because the MySQL server, mysqld, must access the data directory when it runs later, you
       should either run mysql_install_db from the same system account that will be used for
       running mysqld, or run it as root and specify the --user option to indicate the user name
       that mysqld will run as. It might be necessary to specify other options such as --basedir
       or --datadir if mysql_install_db does not use the correct locations for the installation
       directory or data directory. For example:

           shell> scripts/mysql_install_db --user=mysql \
                    --basedir=/opt/mysql/mysql \

           If you have set a custom TMPDIR environment variable when performing the installation,
           and the specified directory is not accessible, mysql_install_db may fail. If so, unset
           TMPDIR or set TMPDIR to point to the system temporary directory (usually /tmp).

       mysql_install_db supports the following options, which can be specified on the command
       line or in the [mysql_install_db] group of an option file. (Options that are common to
       mysqld can also be specified in the [mysqld] group.) Other options are passed to mysqld.
       For information about option files used by MySQL programs, see Section 4.2.6, “Using
       Option Files”.

       ·   --help

           Display a help message and exit.

       ·   --basedir=dir_name

           The path to the MySQL installation directory.

       ·   --builddir=dir_name

           For use with --srcdir and out-of-source builds. Set this to the location of the
           directory where the built files reside.

       ·   --cross-bootstrap

           For internal use. This option is used for building system tables on one host intended
           for another.

       ·   --datadir=dir_name

           The path to the MySQL data directory.

       ·   --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.

       ·   --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.

       ·   --force

           Cause mysql_install_db to run even if DNS does not work. Grant table entries normally
           created using host names will use IP addresses instead.

       ·   --ldata=dir_name

           A synonym for --datadir.

       ·   --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.

       ·   --rpm

           For internal use. This option is used during the MySQL installation process for
           install operations performed using RPM packages.

       ·   --skip-name-resolve

           Use IP addresses rather than host names when creating grant table entries. This option
           can be useful if your DNS does not work.

       ·   --srcdir=dir_name

           For internal use. This option specifies the directory under which mysql_install_db
           looks for support files such as the error message file and the file for populating the
           help tables.

       ·   --user=user_name

           The system (login) user name to use for running mysqld. Files and directories created
           by mysqld will be owned by this user. You must be the system root user to use this
           option. By default, mysqld runs using your current login name and files and
           directories that it creates will be owned by you.

       ·   --verbose

           Verbose mode. Print more information about what the program does.

       ·   --windows

           For internal use. This option is used for creating Windows distributions.
