View the Project on GitHub minio/minio


MINIO QUICKSTART GUIDE





MinIO is a High Performance Object Storage released under GNU Affero General
Public License v3.0. It is API compatible with Amazon S3 cloud storage service.
Use MinIO to build high performance infrastructure for machine learning,
analytics and application data workloads.

This README provides quickstart instructions on running MinIO on bare metal
hardware, including container-based installations. For Kubernetes environments,
use the MinIO Kubernetes Operator.


CONTAINER INSTALLATION

Use the following commands to run a standalone MinIO server as a container.

Standalone MinIO servers are best suited for early development and evaluation.
Certain features such as versioning, object locking, and bucket replication
require distributed deploying MinIO with Erasure Coding. For extended
development and production, deploy MinIO with Erasure Coding enabled -
specifically, with a minimum of 4 drives per MinIO server. See MinIO Erasure
Code Overview for more complete documentation.


STABLE

Run the following command to run the latest stable image of MinIO as a container
using an ephemeral data volume:

podman run -p 9000:9000 -p 9001:9001 \
  quay.io/minio/minio server /data --console-address ":9001"


The MinIO deployment starts using default root credentials
minioadmin:minioadmin. You can test the deployment using the MinIO Console, an
embedded object browser built into MinIO Server. Point a web browser running on
the host machine to http://127.0.0.1:9000 and log in with the root credentials.
You can use the Browser to create buckets, upload objects, and browse the
contents of the MinIO server.

You can also connect using any S3-compatible tool, such as the MinIO Client mc
commandline tool. See Test using MinIO Client mc for more information on using
the mc commandline tool. For application developers, see
https://min.io/docs/minio/linux/developers/minio-drivers.html to view MinIO SDKs
for supported languages.

> NOTE: To deploy MinIO on with persistent storage, you must map local
> persistent directories from the host OS to the container using the podman -v
> option. For example, -v /mnt/data:/data maps the host OS drive at /mnt/data to
> /data on the container.


MACOS

Use the following commands to run a standalone MinIO server on macOS.

Standalone MinIO servers are best suited for early development and evaluation.
Certain features such as versioning, object locking, and bucket replication
require distributed deploying MinIO with Erasure Coding. For extended
development and production, deploy MinIO with Erasure Coding enabled -
specifically, with a minimum of 4 drives per MinIO server. See MinIO Erasure
Code Overview for more complete documentation.


HOMEBREW (RECOMMENDED)

Run the following command to install the latest stable MinIO package using
Homebrew. Replace /data with the path to the drive or directory in which you
want MinIO to store data.

brew install minio/stable/minio
minio server /data


> NOTE: If you previously installed minio using brew install minio then it is
> recommended that you reinstall minio from minio/stable/minio official repo
> instead.

brew uninstall minio
brew install minio/stable/minio

production environments.


DEPLOYMENT RECOMMENDATIONS


ALLOW PORT ACCESS FOR FIREWALLS

By default MinIO uses the port 9000 to listen for incoming connections. If your
platform blocks the port by default, you may need to enable access to the port.


UFW

For hosts with ufw enabled (Debian based distros), you can use ufw command to
allow traffic to specific ports. Use below command to allow access to port 9000

ufw allow 9000


Below command enables all incoming traffic to ports ranging from 9000 to 9010.

ufw allow 9000:9010/tcp



FIREWALL-CMD

For hosts with firewall-cmd enabled (CentOS), you can use firewall-cmd command
to allow traffic to specific ports. Use below commands to allow access to port
9000

firewall-cmd --get-active-zones


This command gets the active zone(s). Now, apply port rules to the relevant
zones returned above. For example if the zone is public, use

firewall-cmd --zone=public --add-port=9000/tcp --permanent


Note that permanent makes sure the rules are persistent across firewall start,
restart or reload. Finally reload the firewall for changes to take effect.

firewall-cmd --reload



IPTABLES

For hosts with iptables enabled (RHEL, CentOS, etc), you can use iptables
command to enable all traffic coming to specific ports. Use below command to
allow access to port 9000

iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart


Below command enables all incoming traffic to ports ranging from 9000 to 9010.

iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
service iptables restart



TEST MINIO CONNECTIVITY


TEST USING MINIO CONSOLE

MinIO Server comes with an embedded web based object browser. Point your web
browser to http://127.0.0.1:9000 to ensure your server has started successfully.

> NOTE: MinIO runs console on random port by default, if you wish to choose a
> specific port use --console-address to pick a specific interface and port.


THINGS TO CONSIDER

MinIO redirects browser access requests to the configured server port (i.e.
127.0.0.1:9000) to the configured Console port. MinIO uses the hostname or IP
address specified in the request when building the redirect URL. The URL and
port must be accessible by the client for the redirection to work.

For deployments behind a load balancer, proxy, or ingress rule where the MinIO
host IP address or port is not public, use the MINIO_BROWSER_REDIRECT_URL
environment variable to specify the external hostname for the redirect. The
LB/Proxy must have rules for directing traffic to the Console port specifically.

For example, consider a MinIO deployment behind a proxy
https://minio.example.net, https://console.minio.example.net with rules for
forwarding traffic on port :9000 and :9001 to MinIO and the MinIO Console
respectively on the internal network. Set MINIO_BROWSER_REDIRECT_URL to
https://console.minio.example.net to ensure the browser receives a valid
reachable URL.

Similarly, if your TLS certificates do not have the IP SAN for the MinIO server
host, the MinIO Console may fail to validate the connection to the server. Use
the MINIO_SERVER_URL environment variable and specify the proxy-accessible
hostname of the MinIO server to allow the Console to use the MinIO server API
using the TLS certificate.

For example: export MINIO_SERVER_URL="https://minio.example.net"

Dashboard Creating a bucket


TEST USING MINIO CLIENT MC

mc provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff
etc. It supports filesystems and Amazon S3 compatible cloud storage services.
Follow the MinIO Client Quickstart Guide for further instructions.


UPGRADING MINIO

Upgrades require zero downtime in MinIO, all upgrades are non-disruptive, all
transactions on MinIO are atomic. So upgrading all the servers simultaneously is
the recommended way to upgrade MinIO.

> NOTE: requires internet access to update directly from https://dl.min.io,
> optionally you can host any mirrors at
> https://my-artifactory.example.com/minio/

 * For deployments that installed the MinIO server binary by hand, use mc admin
   update

mc admin update <minio alias, e.g., myminio>


 * For deployments without external internet access (e.g. airgapped
   environments), download the binary from https://dl.min.io and replace the
   existing MinIO binary let’s say for example /opt/bin/minio, apply executable
   permissions chmod +x /opt/bin/minio and proceed to perform mc admin service
   restart alias/.

 * For installations using Systemd MinIO service, upgrade via RPM/DEB packages
   parallelly on all servers or replace the binary lets say /opt/bin/minio on
   all nodes, apply executable permissions chmod +x /opt/bin/minio and process
   to perform mc admin service restart alias/.


UPGRADE CHECKLIST

 * Test all upgrades in a lower environment (DEV, QA, UAT) before applying to
   production. Performing blind upgrades in production environments carries
   significant risk.
 * Read the release notes for MinIO before performing any upgrade, there is no
   forced requirement to upgrade to latest release upon every release. Some
   release may not be relevant to your setup, avoid upgrading production
   environments unnecessarily.
 * If you plan to use mc admin update, MinIO process must have write access to
   the parent directory where the binary is present on the host system.
 * mc admin update is not supported and should be avoided in
   kubernetes/container environments, please upgrade containers by upgrading
   relevant container images.
 * We do not recommend upgrading one MinIO server at a time, the product is
   designed to support parallel upgrades please follow our recommended
   guidelines.
