Installing System Tables on Unix

Instructions for running the `mariadb-install-db` script on Unix-like systems to initialize the MariaDB data directory and system tables.

mariadb-install-db initializes the MariaDB data directory and creates the system tables in the mysql database, if they do not exist. MariaDB uses these tables to manage privileges, roles, and plugins. It also uses them to provide the data for the help command in the mariadb client.

mariadb-install-db works by starting MariaDB Server's mysqld process in --bootstrap mode and sending commands to create the system tables and their content.

There is a version specifically for Windows, mysql_install_db.exe.

To invoke mariadb-install-db, use the following syntax:

mariadb-install-db --user=mysql
