MariaDB is the open source version of MySQL that is recommended for use on a Raspberry Pi. MySQL isn’t compiled to be working on ARM processors.MariaDB is a direct replacement for MySQL. PMA, also known as PHP My Admin is a way to manage databases without the need to get into the terminal and doesn’t require any knowledge about SQL. MariaDB is one of the most common service used on Raspberry Pi.Since you came to this page I’ll assume you …

Intro So what is Proxmox? Before we take a look at the installation and web UI, we’ll talk about what Proxmox is.Proxmox alone doesn’t tell you what you are running. Proxmox has, at the day of release of this blog, 3 different types of OS’s. Yes Proxmox is a OS based upon Debian. Proxmox VE (Virtual Environment) Proxmox Backup Server Proxmox Mail Gateway Proxmox Backup Server is an OS specialized in Backing up your VM’s, thought any NAS will do …
In the first 2 episodes in the Node-Red series we’ve seen how to install node red in a correct way. In this episode we’ll upgrade our little demo flow we created to a simple network monitoring tool. So let’s continue where we left of in the first episode. Requirements Nodes: node-red-configurable-ping node-red-dashboard node-red-contrib-ui-led node-red-contrib-ui-ping Install the above using the node-red palette or in a terminal using the npm install command Pinging your Router First ting you need to know when …
Having installed node-red you’ll most likely want to use it with more then the standard nodes. Of course you can use a function with and execute node for all missing parts, but why would you reinvent the wheel? In node-red there is the option of install new nodes. This makes it possible to install nodes created by other Node-Red users. You can search for new nodes on this website or in the palette window shown below. The palette can be …
Ever had the misfortune that the IP address of your pi just changed? If you have you probably have to scan your network again with a scanning tool of your flavor.If the IP address of you Raspberry Pi changes all the time, it’s because you’re using a dynamic IP address. Now if you want your Pi’s ip to remain the same you’ll need to assign a static IP address. With a static IP you’ll never have to worry again that …
In our Pi-Hole tutorial we set up an ad-blocking on a Raspberry Pi.In this tutorial we’ll set up a second Pi-Hole server but we’ll link it with the server we set up before. We’ll use Gravity to sync between both. This will create a High Availability Pi-hole server. Requirements 2nd Raspberry Pi or server.Network connection. (or wifi) Setup First you’ll need to setup the second pihole server like we did in the tutorial.Once set up, head over to the Web …
In the previous tutorial we took a look at how to enable and blink a led.Thought this is handy on its own, we want to take a look at user input using a small button. And that’s what we are doing today. Requirements The requirements didn’t change from last episode. but we do need extra wires, switch and resistor Raspberry Pi 3B+ (any Pi with 40 pin headers will do) Ethernet/Wifi connection (micro) sd card with Raspberry Pi OS Dupont …
The Raspberry Pi has made a massive impact in the computer science education. But lets not forget the impact it has made in electronics and the IoT community. These days with the Pi 3B+ and the Pi 4B they are getting really good-value computers, but lets not forget that these small things can be great for home servers to. Lets look a little in the electronics world today. We’ll be using a Rpi B version (any will do) a breadboard …
So lets talk Pi.We already gave a quick overview on the available Pi’s and which one you should chose.But we can doe better then a 5 min read on that. Lets begin with listing all the available Raspberry Pi modules from old to new. Raspberry Pi A (2012) Raspberry Pi B (2012) Raspberry Pi A+ (2014) Raspberry Pi B+ (2014) Raspberry Pi Compute Module (2014) Raspberry Pi 2B (2015)* Raspberry Pi Zero (2015) Raspberry Pi Zero W (2015) Raspberry Pi …
A KVM switch is a piece of hardware that allows you to control multiple computers from one set of keyboard, monitor and mice.In this post we’ll take a closer look in a KVM constructed around a Raspberry Pi 3B+ or 4B. This version of KVM is able to work over the internet. This makes it possible to do remote reboots and/or shutdowns, installations and so on.A quick quote from the Pi-KVM team: A very simple and fully functional Raspberry Pi-based …
Hi there, In E2 of this series we installed ansible on to our master node.Since then there have been a few updates that are not yet included in the repository.So we’ll manually update using 2 lines of code and using ansible to do so.So since this is a 2 line update this is not a full episode. Updating Ansible Copy-paste the 2 lines of code below using your ansible user and see the fun.As of December 2020 the ansible in …
This tutorial continues where we left of in the Backing up your Pi tutorial.We’ve already seen how you can create a backup/clone of your pi to an SD card with the same or bigger size as the one you are using at that moment.In this tutorial I’ll demonstrate a way to clone your SD card (live) to a smaller SD card, this time without the need of a bigger SD card as in the previous tutorial. Requirements For this to …
