Start command
The start command starts a SurrealDB server in memory, on disk, or in a distributed setup.
BEFORE YOU START : Make sure you’ve installed SurrealDB — it should only take a second!

Example usage
To display the current command-line tool version, along with the platform and architecture, in a terminal run the surreal version.
surreal version
Strict mode
SurrealDB supports the ability to startup in strict mode. When running in strict mode, all NAMESPACE, DATABASE, and TABLE definitions will not be created automatically when data is inserted. Instead, if the selected namespace, database, or table has not been specifically defined, then the query will return an error.
surreal start --strict --log debug memory
Authentication
Authentication mode is not enabled by default in SurrealDB. When not enabled, any guest user is considered to have the same permissions as a root user with the OWNER role.
NOTE: It is strongly recommended to enable --auth mode when deploying SurrealDB in production. Not having it enabled can result in unauthorised access to your database.
surreal start --auth --user [ROOT_USER_NAME] --pass [ROOT_USER_PASSWORD]
Command help
To see the help information and usage instructions, in a terminal run the surreal start --help command without any further arguments. This command gives general information on the arguments, inputs, and additional options for the start command.
