Home built blob storage server

In the hopes of creating a "blob" like storage like Amazon S3, I recently did a Google for open source blob storage.  To my pleasure, I discovered minio.  Minio allows me to expose an S3 compatible service locally on my home network.  I can now work with large datasets in a S3-like fashion locally without having the overhead of dealing with an Internet connection.

I can also set up Minio to be a gateway to Amazon S3 or even to my local Hadoop cluster.

I also am able to set up the AWS CLI to interact with minio or have the minio client interact with AWS S3.

While redundancy can be implemented with minio, I'll save that as a project for later.

I picked up a Raspberry Pi 4 8 GB model from Amazon ($150) and a 8 TB external USB drive from Costco ($120).  One can always step down to a lower model / storage space if needed - just couldn't resist the savings on an 8 TB drive from Costco. :)

I downloaded the Raspbian Lite image, set up regionalization and my hostname.  Attached the USB drive and created a brand new ext3 partition on the USB drive, wiping out everything else.  Formatted and attached the drive and made sure it came up on reboots.


Then I downloaded minio using the wget process.  

    wget https://dl.minio.io/server/minio/release/linux-arm/minio
    wget https://dl.minio.io/client/mc/release/linux-arm/mc
    sudo ln -s /home/pi/minio /usr/bin/minio
    sudo ln -s /home/pi/mc /usr/bin/mc


Then I made a simple shell script (start.sh) to launch minio.

    #!/bin/bash
 
    export MINIO_ACCESS_KEY=SuperSecretAccessKey
    export MINIO_SECRET_KEY=SuperSecretSecretKey
    export MINIO_DOMAIN=blobstorage
    export MINIO_DISK_USAGE_CRAWL=off
 
    /usr/bin/minio server /mnt/data


Then I made a file 

    /etc/systemd/system/minio.service

Inside the file I put the following:

    [Unit]
    Description=Minio Storage Service
    After=network-online.target mnt-data.mount

    [Service]
    ExecStart=/home/pi/start.sh
    WorkingDirectory=/mnt/data
    StandardOutput=inherit
    StandardError=inherit
    Restart=always
    User=pi
 
    [Install]
    WantedBy=multi-user.target


I then verified the service worked as intended:

    $ sudo systemctl start minio
    $ sudo systemctl status minio

Opened my browser, and once I logged in, I was able to access the minio service via browser and I made an alias for my minio client.

Home built Hadoop analytics cluster: Part 4

Home built Hadoop analytics cluster: Part 4 So yay!  As mentioned for my next goals in my previous post , I finally got the remaining two boxes built out and added into my home network.  I opted to put the Hadoop cluster on it's own subnet with a dedicated unmanaged switch only for the cluster (primary and nodes). I added the agent and metrics to all of the nodes and rebooted the servers. Then I followed the instructions to set up the cluster, naming it "ds730" after the class that I'm currently taking - DS730: Big Data - High Performance Computing. I also made sure I had DNS setup correctly by modifying /etc/systemd/resolved.conf and fixed my name resolution issues. Removed firewall rules. Removed timedatectl by doing: sudo timedatectl set-ntp no Then installed ntp: sudo apt install ntp Now I need to look at installing some database drivers, however I think I'm going to call it a night.

Home built Hadoop analytics cluster: Part 3

Home built Hadoop analytics cluster: Part 3 In my previous post I covered Bill of Materials (BOM), hardware assembly, and installing Linux (Ubuntu).  In this post I will cover how I installed Ambari. Installing Ambari Rather than build from source, I opted to use the distribution from Cloudera (formerly HortonWorks). Ambari 2.7.5 requires official support from Cloudera, so I went down to 2.7.3 which doesn't require a support agreement with Cloudera. Install some pre-requisites sudo apt install python-dev sudo apt install gcc Add Cloudera as a distribution sudo wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu18/2.x/updates/2.7.3.0/ambari.list sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD sudo apt-get update Verify packages show up apt-cache showpkg ambari-server apt-cache showpkg ambari-agent apt-cache showpkg ambari-metrics-assembly Install and setup the server on primary sudo apt-get install ambari-se...
