Section 1 — Installing and configuring the MinIO server
[!IMPORTANT] Supported MinIO Version: The module works exclusively with MinIO server version
RELEASE.2025-04-22T22:12:26Zor lower.
Update packages and download the compatible MinIO binary:
sudo apt update
# Download the supported release (RELEASE.2025-04-22T22-12-26Z):
wget https://dl.min.io/server/minio/release/linux-amd64/archive/minio.RELEASE.2025-04-22T22-12-26Z -O minio
Install the binary and set up the MinIO user:
sudo chmod +x minio
sudo mv minio /usr/local/bin
sudo useradd -r minio-user -s /sbin/nologin
sudo chown minio-user:minio-user /usr/local/bin/minio
sudo mkdir /usr/local/share/minio
sudo chown minio-user:minio-user /usr/local/share/minio
sudo mkdir /etc/minio
sudo chown minio-user:minio-user /etc/minio
Create the environment configuration file /etc/default/minio:
MINIO_ACCESS_KEY="minio"
MINIO_VOLUMES="/usr/local/share/minio/"
MINIO_OPTS="-C /etc/minio --address :9000 --console-address :9001"
MINIO_SECRET_KEY="miniostorage"
Section 2 — Installing the Systemd MinIO startup script
Create the service file /etc/systemd/system/minio.service:
[Unit]

Section 3 — Starting the MinIO Server
sudo systemctl daemon-reload
sudo systemctl enable minio
sudo systemctl start minio
sudo systemctl status minio
Section 4 — Securing Access to MinIO Server with Let's Encrypt SSL/TLS Certificate
Install certbot and nginx:
sudo apt update
sudo apt install certbot nginx python3-certbot-nginx -y
Create the nginx configuration file /etc/nginx/sites-enabled/minio:
server {
listen 80 default_server;
server_name yourdomain.com;
return 301 https://$host$request_uri;
}
server {
listen 443 ssl http2;
server_name yourdomain.com;
ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/yourdomain.com/cert.pem;

proxy_connect_timeout 300;
proxy_http_version 1.1;
proxy_set_header Connection "";
chunked_transfer_encoding off;
proxy_pass http://localhost:9001;
}

Remove the default nginx config and generate SSL certificate:
rm /etc/nginx/sites-enabled/default
sudo certbot --nginx -d yourdomain.com
sudo service nginx restart
Add certificate auto-renewal to crontab:
0 12 * * * /usr/bin/certbot renew --quiet
