Settings Overview

The minio server process stores its configuration in the storage backend directory.

MinIO Settings

MinIO settings define runtime behavior of the MinIO server process.

You can establish or modify settings by defining:

  • an environment variable on the host system prior to starting or restarting the MinIO Server. Refer to your operating system’s documentation for how to define an environment variable.

  • a configuration setting using mc admin config set.

  • a configuration setting using the MinIO Console’s Administrator > Settings pages.
