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 \--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
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.
