Do you want to setup your private S3 compatible Object storage server?. Minio is a lightweight object storage server compatible with Amazon S3 cloud storage service. Minio is written in Go and licensed under Apache License v2.0.
Object storage is best suited for storing unstructured data such as videos, photos, log files, container images, VM images, and backups. Each size of an object can range from a few KBs to a maximum of 5TB.
Installing Minio Object Storage Server on Linux
Minio object storage server can be installed from a binary file or by running it in a container. I won’t do container installation because it is not an ideal way of setting up a storage server.
Step 1: Download Minio
Download Minio binary.
wget https://dl.minio.io/server/minio/release/linux-amd64/minio
chmod +x minio
sudo mv minio /usr/local/bin/You can query package details using version option.
$ minio -version
inio version RELEASE.2023-08-16T20-17-30Z (commit-id=d09351bb10883d1b55579d11ad68efafaa86b700)
Runtime: go1.19.12 linux/amd64

After Minio is downloaded, let’s prepare a block device that we’ll use to store objects. The path used can just be a directory inside your file system root.
For convenience and reliability, I’m using a secondary disk in my server.
# lsblk | grep sdb
sdb 8:16 0 10G 0 disk I’ll create a new partition and mount this disk to /data directory.
sudo parted -s -a optimal -- /dev/sdX mklabel gpt
sudo parted -s -a optimal -- /dev/sdX mkpart primary 0% 100%
sudo parted -s -- /dev/sdX align-check optimal 1
sudo mkfs.ext4 /dev/sdX1
sudo mkdir /data
sudo mount -a
Configure /etc/fstab
$ sudo vim /etc/fstab
/dev/sdX1 /data ext4 defaults 0 0
Confirm disk mount
$ df -h | grep /data
/dev/sdb1 9.8G 37M 9.3G 1% /dataStep 3: Start Minio service
You have three options of starting a Minio Server.
- From command line – interactive session
- Using Systemd
- Using Sysvinit / Upstart
Managing Minio Service with systemd
For guys running a system with systemd init system, create a user and group for running Minio service.
sudo groupadd --system minio
sudo useradd -s /sbin/nologin --system -g minio minio
Give minio user ownership for the /data directory.
sudo chown -R minio:minio /data/Create systemd service unit file for Minio.
sudo vim /etc/systemd/system/minio.serviceAdd below contents to the file.
[Unit]
Description=Minio
Documentation=https://docs.minio.io
Wants=network-online.target
After=network-online.target
AssertFileIsExecutable=/usr/local/bin/minio
[Service]
WorkingDirectory=/data
User=minio
Group=minio
EnvironmentFile=-/etc/default/minio
ExecStartPre=/bin/bash -c "if [ -z \"${MINIO_VOLUMES}\" ]; then echo \"Variable MINIO_VOLUMES not set in /etc/default/minio\"; exit 1; fi"
ExecStart=/usr/local/bin/minio server $MINIO_OPTS $MINIO_VOLUMES
# Let systemd restart this service always
Restart=always
# Specifies the maximum file descriptor number that can be opened by this process
LimitNOFILE=65536
# Disable timeout logic and wait until process is stopped
TimeoutStopSec=infinity
SendSIGKILL=no
[Install]
WantedBy=multi-user.target
Create Minio environment file /etc/default/minio
sudo mkdir -p /etc/default/
cat <<EOF | sudo tee /etc/default/minio
# Volume to be used for Minio server.
MINIO_VOLUMES="/data"
# Use if you want to run Minio on a custom port.
MINIO_OPTS="--address :9000"
# Access Key of the server.
MINIO_ACCESS_KEY=BKIKJAA5BMMU2RHO6IBB
# Secret key of the server.
MINIO_SECRET_KEY=V7f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12
EOFMINIO_ACCESS_KEY: Access key of minimum 3 characters in length.
MINIO_SECRET_KEY: Secret key of minimum 8 characters in length.
Reload systemd and start minio service
sudo systemctl daemon-reload
sudo systemctl start minioA check on status should show running.
You can also set the service to start on boot.
sudo systemctl enable minioStep 4: Configure Firewall
If you have an active firewall service, allow port 9000.
For UFW, use:
sudo ufw allow 9000For firewalld, use:
sudo firewall-cmd --zone=public --add-port=9000/tcp --permanent
sudo firewall-cmd --reloadStep 5: Access Minio Web interface
Now that we have installed Minio, started the service and configured firewall, we can visit the web dashboard URL to finish login and create the first test bucket.
Visit the URL http://[serverip|localhost]:9000 from your browser and login with the configured Access and Secret key.
On logging, you should get to an object web interface which looks similar to below.
You can create a test bucket from the UI by clicking on the “+” button at the right bottom corner.
Provide bucket name and press enter key.
Step 6: Test Minio with mc client
mc provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. Download mc to your Linux.
wget https://dl.minio.io/client/mc/release/linux-amd64/mc
chmod +x mc
sudo mv mc /usr/local/bin
mc --helpSetup autocompletion
sudo wget https://raw.githubusercontent.com/minio/mc/master/autocomplete/bash_autocomplete
sudo mv bash_autocomplete /etc/bash_completion.d/mc
source /etc/bash_completion.d/mcAnd enjoy tab completion feature.
$ mc <TAB>Configure mc for Minio:
mc config host add <ALIAS> <YOUR-S3-ENDPOINT> <YOUR-ACCESS-KEY> <YOUR-SECRET-KEY> <API-SIGNATURE>Example:
mc config host add minio http://10.0.2.15 BKIKJAA5BMMU2RHO6IBB V7f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12 --api S3v4Sample output:
Follow the complete guide on Use mc with Minio Server to get started with mc.
You can also explore further like using AWS CLI, s3cmd e.t.c.
