| Headless - this is preparing the Raspberry Pi SD card so that when it starts up you don't need a screen, keyboard or mouse attached, just use a remote connection to it | To use option 1 in the office you will need - a PC/Mac with an SD or micro SD card slot and - Raspberry Pi imager software, to create the image on site or in the office, a phone or PC/Mac - Fing software, to find the IP address of the Raspberry Pi once running - an SSH remote control software, to configure it - a VNC remote control software, to operate it |
|||||||||
| Connected - where you plug in all the peripherals and can operate it like a standalone PC for configuration, for example, when you don't know the WiFi information. | To use option 2 in the office you will
need - a USB key - a USB mouse - an HDMI terminal To operate and configure on site or in the office, either - a USB key - a USB mouse - an HDMI terminal or on a phone or PC/Mac - Fing software, to find the IP address of the Raspberry Pi once running - a VNC remote control software, to operate it |

For the Raspberry Pi Imager, to build a Micro SD card to boot from https://www.raspberrypi.com/software/ For Fing to find the Raspberry pi IP address on the network, available free for most platforms. https://www.fing.com/products For VNC remote control of Raspberry Pi without screen keyboard, mouse, available free for most platforms. https://www.realvnc.com/en/connect/download/viewer/ SSH depends on platform Download and install Raspberry Pi Imager to a computer with an SD card reader. Put the SD card you'll use with your Raspberry Pi into the reader and run Raspberry Pi Imager. Load default image and be sure to Config before starting and enter and enable everything. https://www.youtube.com/watch?v=u8bbp79haN4 https://www.youtube.com/watch?v=gGCtbn0d5uQ SSH to devicename@ip address //sudo ln -s /usr/lib/systemd/system/vncserver-x11-serviced.service /etc/systemd/system/multi-user.target.wants/vncserver-x11-serviced.service //sudo systemctl start vncserver-x11-serviced sudo raspi-config enable VNC sudo reboot sudo shutdown sudo apt update sudo apt upgrade Flask already installed //sudo apt install python3-venv // sudo apt-get install python3-flask cd Documents mkdir rpiWebServer cd rpiWebServer mkdir static mkdir templates // sudo python3 RestAPI.py #!/bin/bash export FLASK_APP=RestAPI.py flask run --host=0.0.0.0 Setup automatic start sudo nano /lib/systemd/system/RestfulAPI.service RestfulAPI.service = [Unit] Description=Start Restful API server After=multi-user.target [Service] ExecStart=sh /home/pi3/Desktop/startup.sh [Install] WantedBy=multi-user.target or ExecStart=/home/pi3/Desktop/startup.sh sudo systemctl daemon-reload sudo systemctl enable RestfulAPI.service systemctl status RestfulAPI sudo systemctl stop RestfulAPI.service sudo systemctl status RestfulAPI.service edit wifi Generate PSK - make sure SSID has correct case and password wpa_passphrase my_SSID my_password Add to this file sudo nano /etc/wpa_supplicant/wpa_supplicant.conf |
