Setting Up an Object Storage Server with MinIO on Ubuntu 18.04

In recent years, the demand for cloud storage solutions has surged dramatically. Businesses and individuals alike are seeking cost-effective, reliable, and scalable options to store and manage data. Among the various storage solutions available, object storage has emerged as a favorite, primarily due to its flexibility and scalability. One of the most popular open-source object storage solutions is MinIO, which is ideal for developers and organizations looking to implement high-performance object storage systems. In this article, we’ll guide you through setting up an object storage server with MinIO on Ubuntu 18.04.

Understanding Object Storage and MinIO

Before diving into the setup process, let's clarify what object storage is and why MinIO is an excellent choice for this purpose.

Object Storage is designed to handle large amounts of unstructured data, such as documents, images, and videos. Unlike traditional file systems that store data in hierarchical structures, object storage manages data as objects. Each object contains the data itself, metadata, and a unique identifier, making it easy to retrieve and manage.

MinIO, on the other hand, is a high-performance, distributed object storage server compatible with Amazon S3. It allows you to manage your data effectively while providing features like scalability, security, and high availability.

Prerequisites

To follow this guide, ensure you have the following prerequisites:

  1. Ubuntu 18.04 server with root access or a user account with sudo privileges.
  2. A basic understanding of command-line operations.
  3. Internet access for downloading MinIO and related packages.

Step 1: System Preparation

Before installing MinIO, we need to update the server’s package index and install any available upgrades. This ensures that our installation will proceed smoothly without any issues stemming from outdated packages.

Open your terminal and run:

sudo apt update && sudo apt upgrade -y

Step 2: Install Required Dependencies

MinIO is a lightweight application that relies on a few essential dependencies. While it doesn't require many additional tools, it’s a good idea to have curl installed for downloading files. You can install it by running:

sudo apt install curl -y

Step 3: Downloading and Installing MinIO

Now that your server is up to date, it's time to download the MinIO binary. You can use curl to download it directly from the official website:

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

Once the download is complete, we need to make the MinIO binary executable:

chmod +x minio

To make it easier to run MinIO, we can move it to the /usr/local/bin directory:

sudo mv minio /usr/local/bin/

Step 4: Creating a User and Setting Up Directories

For security reasons, it's best to create a dedicated user for running MinIO. Let's create a user named minio-user and a directory for storing the MinIO data.

sudo useradd -r minio-user -s /sbin/nologin
sudo mkdir /data
sudo chown minio-user:minio-user /data

This setup ensures that only the minio-user can access the data directory.

Step 5: Configuring MinIO

To run MinIO, we need to configure it. We’ll create a systemd service file, which will allow us to run MinIO as a service and manage it easily.

Create a new file named minio.service in the systemd directory:

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

Add the following content to the file:

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

[Service]
User=minio-user
Group=minio-user
ExecStart=/usr/local/bin/minio server /data --console-address ":9001"
Restart=always

[Install]
WantedBy=multi-user.target

In this configuration:

  • The ExecStart line specifies where MinIO is installed and the directory for storing data. The --console-address ":9001" flag specifies the port for the MinIO console interface.

Step 6: Starting and Enabling MinIO Service

Now, we can start the MinIO service and enable it to run at boot time. Run the following commands:

sudo systemctl start minio
sudo systemctl enable minio

To check the status of the MinIO service and ensure it's running, use:

sudo systemctl status minio

If everything is working correctly, you should see the status as active (running).

Step 7: Accessing the MinIO Web Interface

MinIO provides a web-based interface to manage your storage. By default, this interface is accessible via port 9001. Open your web browser and enter the following URL:

http://<your-server-ip>:9001

You will be prompted to enter credentials. By default, MinIO requires an access key and secret key. To generate these keys, we will modify our service file with environment variables.

Edit the minio.service file again:

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

Add the following lines in the [Service] section:

Environment=MINIO_ACCESS_KEY=your-access-key
Environment=MINIO_SECRET_KEY=your-secret-key

Remember to replace your-access-key and your-secret-key with your desired credentials. After making these changes, save the file and reload the systemd manager:

sudo systemctl daemon-reload
sudo systemctl restart minio

Now, go back to your browser and enter the same URL. Use the access and secret keys you set to log in.

Step 8: Using MinIO for Object Storage

With MinIO up and running, it’s time to explore its functionality. Here are some essential tasks you can perform within the MinIO web interface:

Uploading Files

  1. Create a Bucket: Click on "Buckets" in the left-hand menu and select "Create Bucket." Give your bucket a unique name and click "Create."

  2. Upload Objects: Within your newly created bucket, you can easily upload files by clicking the "Upload" button.

Managing Files

After uploading files, you can organize them within buckets, set permissions, and delete objects as needed.

Accessing Files via S3 API

Since MinIO is compatible with the S3 API, you can use AWS SDKs and CLI tools to interact with your MinIO server programmatically. Ensure that you set the endpoint to your MinIO server’s address and use the credentials you created earlier.

Conclusion

Setting up an object storage server with MinIO on Ubuntu 18.04 provides a powerful solution for storing and managing large amounts of data. The installation process is straightforward, and the flexibility of MinIO allows you to scale your storage needs effortlessly. With its S3 compatibility, you can integrate MinIO into existing applications that rely on object storage.

In a world where data is growing exponentially, having a reliable object storage solution is essential. Whether for personal projects, development environments, or business needs, MinIO offers a robust platform to meet your requirements.
