Installing System Tables on Windows

The mariadb-install-db.exe utility is the Windows equivalent of mariadb-install-db.

Functionality

The functionality of mariadb-install-db.exe is comparable with the shell script mariadb-install-db used on Unix, however it has been extended with both Windows specific functionality (creating a Windows service) and to generally useful functionality. For example, it can set the 'root' user password during database creation. It also creates the my.ini configuration file in the data directory and adds most important parameters to it (e.g port).

mariadb-install-db.exe is used by the MariaDB installer for Windows if the "Database instance" feature is selected. It obsoletes similar utilities and scripts that were used in the past such as mysqld.exe --install,mysql_install_db.pl, and mysql_secure_installation.pl.

My apologies. You are correct. Here is the same formatted content presented in a proper markdown table.

Parameter(s)	Description
-?, --help	Display help message and exit
-d, --datadir=name	Data directory of the new database
-S, --service=name	Name of the Windows service
-p, --password=name	Password of the root user
-P, --port=#	mysqld port
-W, --socket=name	named pipe name
-D, --default-user	Create default user
-R, --allow-remote-root-access	Allow remote access from network for user root
-N, --skip-networking	Do not use TCP connections, use pipe instead
-i, --innodb-page-size	Innodb page size, since MariaDB 10.2.5
-s, --silent	Print less information
-o, --verbose-bootstrap	Include mysqld bootstrap output
-l, --large-pages	Use large pages, since MariaDB 10.6.1
-c, --config	my.ini config template file, since MariaDB 10.6.1

To create a Windows service, mariadb-install-db.exe should be run by a user with full administrator privileges (which means elevated command prompt on systems with UAC).

Example

mariadb-install-db.exe --datadir=C:\db --service=MyDB --password=secret

will create the database in the directory C:\db, register the auto-start Windows service "MyDB", and set the root password to 'secret'.

To start the service from the command line, execute

sc start MyDB

Removing Database Instances

If you run your database instance as service, to remove it completely from the command line, use

sc stop <servicename>
sc delete <servicename>
rmdir /s /q <path-to-datadir>
