MinIO

MinIO#

MinIO offers high-performance, S3 compatible object storage.

You can install multiple MinIO instances on the same node from the Software center.

Configuration#

MinIO needs two dedicated virtual host, a FQDN like minio-api.nethserver.org and minio-ui.nethserver.org.

Before proceeding with the configuration, make sure to create the corresponding name records inside your DNS server. If you are planning to use a Let’s Encrypt certificate as default, make also sure to have corresponding public DNS records.

How to configure:

  1. access the application configuration page and enter the API server host name: this will be the FQDN used by hosts to connect to S3 services

  2. fill the Web interface host name: you will be able to configure your MinIO instance from this FQDN

  3. enable Let's Encrypt option accordingly to your needs

  4. click the Save button

  5. open the entered host name inside the browser, eg: https://minio-ui.nethserver.org.

Configure local disks#

Setting up MinIO with a locally attached USB/SCSI disk provides two key benefits:

  1. data privacy: if you’re cautious about sharing data with cloud providers, this setup allows you to retain control over your information and prevent third-party access

  2. local data ownership: by utilizing a local disk, you maintain complete data control within your own environment. This improves security and minimizes dependence on external services

Instructions#

As system root user, follow these steps for a disk named scsi-disk1:

  1. Create a mount point: make a directory to serve as the mount point for the disk:

    mkdir -p /mnt/data

  2. Automate mount at boot: ensure the disk is automatically mounted during boot by modifying /etc/fstab:

    echo '/dev/disk/by-id/scsi-disk1 /mnt/data ext4 defaults,nofail,discard 0 0' >> /etc/fstab
systemctl daemon-reload

  3. Mount the disk: physically attach the disk using the mount command:

    mount /mnt/data

  4. Ensure MinIO access: allow the MinIO instance (e.g., minio1) to access the disk:

    chown minio1:minio1 /mnt/data/

Finally, within the module’s user interface, configure the Storage path to be /mnt/data. Please note that the above path won’t be part of the backup.
