Raspberry Pi

this procedure Installs FTS + UI + video Server onto a Raspberry Pi

Hardware requirements

you need a RaspPi with at least 4 GB RAM

Procedure

Prepare an SD Card

Start with new installation of ubuntu 22.04 server for RaspPi 64. FTS 2.x expects Ubuntu 22.04 (64 bit).

You will need an imager.

Follow the instructions to prepare an SD card with the appropriate image.

The rpi-imager provides a means for setting an ssh authorized key and default username and password.

I construct an ssh key-pair specifically for working with compute nodes. Construction of such key-pairs is done with ssh keygen. Presume that the key-pair thus generated is ~/.ssh/fts_rsa and ~/.ssh/fts_rsa.pub.

Setup Hardware

  • insert the prepared SD card into the Raspberry Pi.
  • connect a keyboard
  • connect a monitor
  • connect to an ethernet network

Update the OS

The initial setup takes ~5 minutes on a RaspPi 4 Login with fts / ubuntu (or whichever user you selected)

If the RaspPi is connected to your router, when it boots it will display the IP grabbed from DHCP server. Write down the IP address, we will need it later.

sudo apt update -y 
sudo apt upgrade -y
You may be prompted during the upgrade. Generally, accepting the defaults is appropriate.

In some cases you need to run: sudo apt full-upgrade or sudo apt-get dist-upgrade.

It is generally easier to communicate with your server via ssh. You will need the IP address (you should write the address down for later reference). 

sudo apt install -y net-tools

ip addr show
Here is representative fragment from an output. 
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether d8:3a:dd:5f:27:24 brd ff:ff:ff:ff:ff:ff
    inet 10.2.118.237/24 metric 100 brd 10.2.118.255 scope global dynamic eth0
       valid_lft 53818sec preferred_lft 53818sec
    inet6 fe80::da3a:ddff:fe5f:2724/64 scope link
       valid_lft forever preferred_lft forever
The IP address in this case is 10.2.118.237. This is the same address you may have captured earlier during initial boot.

Multiple reboot may be required to get the OS fully updated. 

sudo reboot

From here on it should be possible to connect via ssh. Here is an example with the IP address obtained previously and fts user. 

ssh fts@10.2.118.237
I generally update the ~/.ssh/config file with this information: 
Host fts-rp1
    HostName 10.2.118.237
    User fts
    IdentityFile ~/.ssh/fts_rsa

Update Prerequisites

Verify the following packages are installed. 

sudo apt install -y wget curl

Install FTS on the Raspberry Pi

Yow will probably need to install with an explicit IP address.

The complete ZTI instructions are here.

Getting Support

Support is provided on the FTS Discord server by volunteers.

Use the Discord #installation-support-pi Support channel.

RPiFTS Series

GHOST_DA-B6 has created a set of videos on youtube detailing how to install and set up FTS on raspberry pi SBC's.

You can view his RPiFTS video series on his channel.
