mysql_install_db - initialize MariaDB data directory
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 \
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.
The path to the MariaDB installation directory.
If using --srcdir with out-of-directory builds, you will need to
set this to the location of the build directory where built files
For internal use. Used when building the MariaDB system tables on a
different host than the target..

Do not read default options from any option file. This must be
given as the first argument.
Print the program argument list and exit. This must be given as

For internal use. This option is used by RPM files during the
MariaDB installation process.
Use IP addresses rather than host names when creating grant table
entries. This option can be useful if your DNS does not work.
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.
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
