How to self host your own object storage.

How to self host your own object storage.

Cloud storage solutions like Amazon S3 are powerful, but they come with ongoing costs and potential privacy concerns. If you need an S3-compatible object storage solution that you control, MinIO is an excellent choice. MinIO is a high-performance, open-source storage system that allows you to self-host object storage on your own infrastructure, whether on-premise or in the cloud.

Why self host MINIO?

  • Data Ownership and Privacy: You have complete control over your data, ensuring it resides on infrastructure you manage, mitigating concerns about third-party access or data breaches.

  • Cost Savings: Depending on your storage needs, self-hosting can be significantly cheaper than relying on commercial cloud storage providers, especially for large volumes of data.

  • Customization and Flexibility: You can tailor the MinIO configuration to your specific requirements, integrating it seamlessly with your existing infrastructure and applications.

  • Performance Optimization: Hosting MinIO closer to your applications can reduce latency and improve data access speeds.

  • Learning and Experimentation: Self-hosting provides a valuable learning experience, allowing you to understand the intricacies of object storage and server administration.

Prerequisites:

To follow this guide, you will need:

  • An Ubuntu VPS: You'll need access to a virtual private server running Ubuntu. Ensure you have SSH access to the server.

  • Basic Linux Command Line Knowledge: Familiarity with basic Linux commands will be helpful.

  • A Domain Name (Optional but Recommended): Using a domain name allows for easier access and management of your MinIO instance. You'll need to configure DNS records to point to your VPS IP address.

2. Update System Packages:

It's always a good practice to start by updating your system packages to ensure you have the latest versions:

terminal 
sudo apt update
sudo apt upgrade -y

3. Install MinIO:

There are several ways to install MinIO. We'll use the official binary for simplicity:

terminal 
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
sudo mv minio /usr/local/bin/

These commands download the MinIO binary, make it executable, and move it to the /usr/local/bin directory, making it accessible system-wide.

To ensure MinIO runs reliably in the background and restarts automatically if it crashes, we'll create a systemd service.

sudo vim /etc/systemd/system/minio.service
minio.service 
[Unit]
Description=MinIO Server
After=network.target

[Service]
WorkingDirectory=/opt/minio
Environment="MINIO_ROOT_USER=your_minio_access_key"
Environment="MINIO_ROOT_PASSWORD=your_minio_secret_key"
ExecStart=/usr/local/bin/minio server /opt/minio --address :9000
Restart=on-failure

[Install]
WantedBy=multi-user.target

Important:

  • Replace your_minio_access_key and your_minio_secret_key with strong, unique credentials. These will be used to access your MinIO server.

  • The WorkingDirectory specifies the directory where MinIO will store its data. We'll create this directory in the next step.

  • --address :9000 tells MinIO to listen on port 9000. You can change this if needed.

Save and close the file.

Why Choose MinIO?

MinIO offers several benefits that make it a great choice for self-hosted object storage:

  • S3 Compatibility – Works seamlessly with applications designed for Amazon S3.

  • High Performance – Optimized for high-speed data storage and retrieval.

  • Scalability – Can be deployed on a single server or scaled across multiple nodes.

  • Security – Supports encryption, access control, and identity management.

  • Lightweight – Requires minimal system resources and is easy to deploy.

Setting Up MinIO

Before installing MinIO, ensure your system meets these basic requirements:

  • A 64-bit Linux, macOS, or Windows machine

  • At least 4GB RAM (recommended)

  • A dedicated disk or storage location for MinIO data

  • A modern CPU with SSE4.2 support

Installing MinIO

terminal 
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
sudo mv minio /usr/local/bin/

Securing MinIO

Conclusion

Self-hosting MinIO gives you full control over your object storage while maintaining S3 compatibility. Whether you need a private cloud solution, backup storage, or a scalable system for your applications, MinIO is a powerful and flexible choice.
