MYSQL_INSTALL_DB()					    MYSQL_INSTALL_DB()

NAME
       mysql_install_db - initialize MySQL data directory

SYNOPSIS
       mysql_install_db [options]

DESCRIPTION
       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, needs to 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 use 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 \
		    --datadir=/opt/mysql/mysql/data

       mysql_install_db needs to invoke mysqld with the --bootstrap and
       --skip-grant-tables options.

	   Note
	   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, see Section 4.2.3.3, “Using Option Files”.
       mysql_install_db also supports the options for processing option files
       described at Section 4.2.3.4, “Command-Line Options that Affect Option-
       File Handling”.

       ·   --basedir=path

	   The path to the MySQL installation directory.

       ·   --datadir=path, --ldata=path

	   The path to the MySQL data directory.

       ·   --force

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

       ·   --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=path

	   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 root 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.
