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.
shell> bin/mysql_install_db --user=mysql \--basedir=/opt/mysql/mysql \--datadir=/opt/mysql/mysql/datamysql_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..

Display a help message and exit.
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
the first argument.
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 current login name and files and directories that it creates
will be owned by you.
