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.

       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 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> bin/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. If MySQL was configured
       with the --disable-grant-options option, --bootstrap and --skip-grant-tables will be disabled (see Section 2.11.4, "MySQL
       Source-Configuration Options"). To handle this, set the MYSQLD_BOOTSTRAP environment variable to the full path name of a
       server that has all options enabled.  mysql_install_db will use that server.

           Note
           If you have set a custom TMPDIR variable when performing the installation, and the specified directory is not
           accessible, the execution of mysql_install_db may fail. You should 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]
       and (if they are common to mysqld) [mysqld] groups of an option file. 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 4.2.3.3.1, "Command-Line Options that Affect Option-File Handling".

       o   --basedir=path

           The path to the MySQL installation directory.

       o   --force

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

       o   --datadir=path, --ldata=path

           The path to the MySQL data directory.

       o   --rpm

           For internal use. This option is used by RPM files during the MySQL installation process.

       o   --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.

       o   --srcdir=path

           For internal use. 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. This option was added in MySQL 5.1.14.

       o   --user=user_name

           The 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.

       o   --verbose

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

       o   --windows

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