MinIO is a high-performance, S3 compatible object storage server designed for large-scale data storage. In this guide, we will walk through the steps to install and configure MinIO on Ubuntu 20.04.

Step 1: Update Your System

Start by ensuring your system is up to date:

sudo apt update && sudo apt upgrade -y

Step 2: Install MinIO

Download the MinIO server binary:

wget https://dl.min.io/server/minio/release/linux-amd64/minio

Make the binary executable:

chmod +x minio

Move MinIO to a system directory:

sudo mv minio /usr/local/bin/

Step 3: Create a MinIO User

Create a dedicated user for running MinIO:

sudo useradd -r minio-user -s /sbin/nologin

Step 4: Create Directories for MinIO

Create directories for MinIO to store data and configuration files:

sudo mkdir /usr/local/share/minio
sudo mkdir /etc/minio

Change ownership of these directories:

sudo chown minio-user:minio-user /usr/local/share/minio
sudo chown minio-user:minio-user /etc/minio

Step 5: Create a Configuration File

Create a configuration file for MinIO:

sudo nano /etc/minio/minio.conf

Add the following configuration:

MINIO_VOLUMES=/usr/local/share/minio
MINIO_ACCESS_KEY=YOUR_ACCESS_KEY
MINIO_SECRET_KEY=YOUR_SECRET_KEY

Replace YOUR_ACCESS_KEY and YOUR_SECRET_KEY with your desired credentials.

Step 6: Create a Systemd Service File

Create a systemd service file for MinIO:

sudo nano /etc/systemd/system/minio.service

Add the following configuration:

[Unit]
Description=MinIO
Documentation=https://min.io/docs/minio/linux/Quickstart Guide.html
After=network.target

[Service]
User=minio-user
Group=minio-user
ExecStart=/usr/local/bin/minio server /usr/local/share/minio --config-dir /etc/minio
Restart=always
EnvironmentFile=/etc/minio/minio.conf

[Install]
WantedBy=multi-user.target

Step 7: Start and Enable MinIO

Reload systemd and start the MinIO service:

sudo systemctl daemon-reload
sudo systemctl start minio
sudo systemctl enable minio

Step 8: Access MinIO Web Interface

By default, MinIO runs on port 9000. You can access the MinIO web interface by navigating to:

http://your_server_ip:9000

Log in using the access key and secret key you configured earlier.

Step 9: Configure a Reverse Proxy (Optional)

If you want to use Nginx as a reverse proxy, install Nginx:

sudo apt install -y nginx

Create a new Nginx configuration file for MinIO:

sudo nano /etc/nginx/sites-available/minio

Add the following configuration:

server {
    listen 80;
    server_name your_domain_or_ip;

    location / {
        proxy_pass http://localhost:9000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Enable the site and restart Nginx:

sudo ln -s /etc/nginx/sites-available/minio /etc/nginx/sites-enabled/
sudo systemctl restart nginx
