 +====== Raspberry Pi4 ======
  
 +How to setup your Raspberry Pi4 device: Assemble your computer.
 +The raspberry pi is a small, single board computer. You will need a second computer to format and install its operating system onto a micro sd card, preferably 128Gb or bigger.
 +
 +Download Raspberry Pi Imager onto your second computer and burn RaspberryPi Os 32bit to your micro sd card. Here's the link [[https://www.raspberrypi.org/blog/raspberry-pi-imager-imaging-utility/]]
 +
 +Here is a link to a complete guide on how to set up the Pi and peripherals. 
 +How to set up your new Raspberry Pi 4 and peripherals ([[https://magpi.raspberrypi.org/articles/set-up-raspberry-pi-4]])
 +
 +How to install Armor Case on your Raspberry Pi 4 ([[https://www.youtube.com/watch?v=5SZkVQ4dd64]])
 +
 +Now that your machine is set up with Raspbian OS, a keyboard and mouse, we can install Qortal.
 +We will be using the Terminal application found in the top left menu to install everything.
 +
 +For clarity all commands to be typed by you are followed by  ↩ symbol to denote pressing enter key.
 +You can also simply copy and paste the relevant text from this guide into the terminal like this:
 +Using your mouse, click and drag the portion to be copied
 +
 +Right click- copy
 +
 +Then right click in terminal
 +
 +And choose  paste
 +
 +Press enter and off you go.
 +
 +You will need Java installed on the raspberry pi as well as 7zip.
 +
 +To install them, open a terminal window by navigating to the start menu and selecting the Terminal app. 
 +
 +#Get your system up to date using:
 + 
 +sudo apt update↩
 +
 +The files will be downloaded and installed. 
 +# Next we will upgrade the entire system to the latest version using:
 +
 +sudo apt full-upgrade↩
 +
 +# It will check what’s needing to be upgraded and a prompt will appear, type y and press enter.
 +
 +y↩
 +
 +# Now we will configure the system to allow remote access via ssh to Raspberry using a remote computer:
 + 
 +sudo raspi-config↩
 +
 +A new window will open.Use your arrow keys to navigate and enter to select.
 +Select option three, to configure peripheral connections and then select and enable SSH. 
 +Navigate to the finish button and press enter.
 +
 +
 +You will find yourself back in the terminal window.
 +# Now that your system is up to date, let's install Java:
 +
 +sudo apt install default-jdk↩
 +
 +# To check if it’s installed properly, type:
 +
 +java -version↩
 +
 +This will display your currently installed version of java and display something like
 +
 +openjdk version "11.0.9.1" 2020-11-04
 +OpenJDK Runtime Environment (build 11.0.9.1+1-post-Raspbian-1deb10u2)
 +OpenJDK Server VM (build 11.0.9.1+1-post-Raspbian-1deb10u2, mixed mode)
 +
 +
 +# Assuming all went well and Java is installed, we now install 7zip:
 +
 +sudo apt-get install p7zip-full -y↩
 +
 +It will be done shortly.
 +
 +
 +
 +Install Qortal Core on your Raspberry Pi 4.
 +
 +# In the terminal:
 +
 +wget https://github.com/Qortal/qortal/releases/download/v1.4.3/qortal-1.4.3.zip↩
 +
 +This will download the core zip file to your PI.
 +# Now we unzip it with:
 +
 +unzip qortal-1.4.3.zip↩
 + 
 +# Then enter the newly unzipped Qortal directory using:
 +
 +cd qortal↩
 +
 +Now we will download the zipped database file:
 +
 +
 +# Type the command:
 +
 +ls↩
 +
 +This will show you a list of all the files in the Qortal folder.
 +It should look like this
 +
 +
 +                log.txt.1   run.log        start.sh
 +log4j2.properties  qortal.jar  settings.json  stop.sh
 +
 +
 +# To download the database type:
 +
 +wget https://qortal.tmgoxford.com/db.7z ↩
 +
 +Be patient. It’s a huge file and will take a while to complete.
 +When it’s done downloading, your prompt will reappear and you can continue installing.
 +# Extract the database:
 +
 +7z x db.7z↩
 +
 +This will also take quite some time.
 +When it’s done extracting, your prompt will reappear and you can continue.
 +# Now you must grant permissions to the scripts in the folder so you can run them:
 +
 +chmod  a+x *.sh↩
 +
 +# Next we edit the configuration file to optimise for raspberry pi:
 +
 +echo -en "{\n\"maxPeers\": 32,\n\"minBlockchainPeers\": 8,\n\"apiDocumentationEnabled\": true\n}\n\"" > settings.json
 +
 +# Let’s make sure it did what is required, let’s display the settings.json file by:
 +
 +cat settings.json↩
 +
 +You should get the following
 +
 +{
 +"maxPeers":32,
 +"minOutboundPeers":16,
 +"minBlockchainPeers":8,
 +"maxNetworkThreadPoolSize":25,
 +"apiDocumentationEnabled":true
 +}
 +
 +# Assuming all went well to this point you can now start the core:
 +
 +./start.sh↩
 +
 +It should tell you it's passed the java version check and give you the PID
 +    Passed Java version check
 +    qortal running as pid (whatever PID digits it assigns)
 +
 +A moment or two later the logo will appear, centre screen and after about 20-30 seconds a small Qortal icon will appear in the top right section of your screen.
 +
 +Give it a minute or two to start making connections and then hover your mouse over the icon. Connection data will appear, synchronisation %, number of peers you are connected to and the current block height you are at.
 +
 +CONGRATULATIONS. Your node is up and running.
 +
 +# To stop it gracefully at any point open a terminal:
 +
 +cd /qortal↩
 +
 +./stop.sh↩
 +
 +Currently it is not easy to setup the User Interface (UI) on the raspberry pi. You can connect the running core on your Raspberry Pi to a second computer that has the UI installed with the following method:
 +On Mac, open the terminal application and tell the mac to set up an SSH connection to your pi using the following command to connect the correct ports:
 +
 +ssh -L 22391:127.0.0.1:12391 pi@your pi’s local ip address↩
 +
 +This takes the output from port 12391 on your pi to port 22391 on your Mac
 +Now we open the UI on the Mac and follow the steps to use this new connection.
 +
 +Select add custom node
 +
 +In the menu, select the following options
 +
 +protocol=http, domain=127.0.0.1, port=22391
 +
 +Click add and on the Settings page and select your newly added node. Login as usual.
 +
 +Instructions for Windows machines will be available shortly or you can ask in Telegram and Discord.
 +
 +An expanded version of this guide will be available soon, with the next steps and a list of useful commands.
