MinIO

MinIO offers high-performance, S3 compatible object storage.

Installation

Install the minio package. The minio-client is optional.

Configuration

The configuration file is located in /etc/minio/minio.conf.

Credentials

Uncomment MINIO_ROOT_USER and MINIO_ROOT_PASSWORD and set them to a value of your choice.

Warning: If MINIO_ROOT_USER and MINIO_ROOT_PASSWORD are not modified, the default login/password will be minioadmin/minioadmin.

Single server with 1 disk

The default configuration will start a single server with a single disk. MinIO objects will be stored in /srv/minio/data. Change the value of MINIO_VOLUMES to update the path.

MINIO_OPTS might contains extra parameters that will be given to the MinIO server when started.

Start MinIO by starting minio.service. Check that MinIO has been started by checking the service's unit status; example output is as follows:

minio[1234]: You are running an older version of MinIO released 1 month ago
minio[1234]: Update: Run `mc admin update`

minio[1234]: WARNING: Console endpoint is listening on a dynamic port (43831), please use --console-address ":PORT" to choose a static port.
minio[1234]: WARNING: Detected default credentials 'minioadmin:minioadmin', we recommend that you change these values with 'MINIO_ROOT_USER' and 'MINIO_ROOT_PASSWORD' environment variables

Note: To prevent MinIO from listening on every interface, add --address 192.168.0.1:9123 to MINIO_OPTS to set the IP address and the port MinIO has to use.

Single server with 4 disks

Edit etc/minio/minio.conf:

MINIO_VOLUMES="/srv/minio/data{0...3}"

or

MNIO_VOLUMES="/srv/minio/foobar /srv/minio/barfoo /srv/minio/faabor /srv/minio/borfaa"

Start minio.service. Verify that MinIO is running by checking its unit status; example output is as follows:
