NAME         top

       mariadb-install-db - initialize MariaDB data directory
       (mysql_install_db is now a symlink to mariadb-install-db)

SYNOPSIS         top

       mysql_install_db [options]

DESCRIPTION         top

       mysql_install_db initializes the MariaDB 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 MariaDB 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 \

       mysql_install_db needs to invoke mysqld with the --bootstrap and
       --skip-grant-tables options (see Section 2.3.2, “Typical
       configure Options”). If MariaDB was configured with the
       --disable-grant-options option, --bootstrap and
       --skip-grant-tables will be disabled. 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.

       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] option file groups.

       •   --basedir=path

           The path to the MariaDB installation directory.

       •   --builddir=path

           If using --srcdir with out-of-directory builds, you will need
           to set this to the location of the build directory where
           built files reside..

       •   --cross-bootstrap

           For internal use. Used when building the MariaDB system
           tables on a different host than the target..

       •   --datadir=path, --ldata=path

           The path to the MariaDB data directory.

       •   --defaults-extra-file=filename

           Set filename as the file to read default options from after
           the global defaults files has been read.  Must be given as
           first option.

       •   --defaults-file=filename

           Set filename as the file to read default options from,
           override global defaults files.  Must be given as first

       •   --defaults-group-suffix=name

           In addition to the given groups, also read groups with this

       •   --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.

       •   --help

           Display a help message and exit.

       •   --no-defaults

           Do not read default options from any option file. This must
           be given as the first argument.

       •   --print-defaults

           Print the program argument list and exit.  This must be given
           as the first argument.

       •   --rpm

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

       •   --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

       •   --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.4.

       •   --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.

       •   --extra-file=file_path

           Add user defined SQL file, to be executed following regular
           database initialization.

       •   --verbose

           Verbose mode. Print more information about what the program

       •   --windows

           For internal use. This option is used for creating Windows
