Epics Installation At Raspberry Pi From Scratch

Detailed Table of Content

Installing Raspbian/Debian image

see e.g. https://www.raspberrypi.org/documentation/installation/installing-images/

    Download Image, Write Image, First Boot, Login

    1. Consult e.g. http://elinux.org/RPi_SD_cards#Working_.2F_Non-working_SD_cards to not purchase wrong SD cards.
    2. Download Image
    3. Write Image to the SD card
    4. Plug SD card into the Raspberry PI
    5. Connect Monitor via HDMI and Keyboard/Mouse
    6. Power on
    7. STRETCH image already ends up at the Desktop GUI logged in as user pi

    For registration purposes extract the SERIAL number and the type of RASPI

      Serial number

      ( e.g. q.v. https://developer-blog.net/raspberry-pi-seriennummer-ausgeben/ )
      cat /proc/cpuinfo | grep Serial | cut -d' ' -f2

      Hardware type, origin

      ( e.g. q.v. https://elinux.org/RPi_HardwareHistory )
      cat /proc/cpuinfo | grep 'Revision' | awk '{print $3}' | sed 's/^1000//'

Configurations

    before connecting to GSI LAN ...

      GSI specific network settings

        IP6 permanent off
        (q.v. https://www.raspberrypi.org/forums/viewtopic.php?t=138899#p1140972 )
        • Add ipv6.disable=1 to /boot/cmdline.txt.
        • don't load ipv6 module at all
        * and https://www.howtoraspberry.com/2020/04/disable-ipv6-on-raspberry-pi/ if still not working * ...

    reboot and connect network ...

    • connect network and
    • sudo reboot

    raspi-config

    1. raspi-config - Raspberry Pi Software Configuration Tool, current settings
      1. To start raspi-config:
        a. console based
        1. open a terminal, either by
          • mouse click, or
          • CTRL-ALT-F2
            • login, if necessary : pi/raspberry
        2. sudo raspi-config
        b. GUI based
        via the system menu → "raspi-config"
      2. If connected to the internet, then update
        • → Update
      3. Localisation Options
        1. Timezone: Change Timezone → Europe → Berlin
        2. Keyboard Layout, (if needed)
          1. Change Keyboard Layout
            1. Generic 105-key (Intl) PC__→ __Other, (if not English) → German → German
            2. Key to function as AltGr: Right Alt (AltGr)
            3. Compose key: No compose key
            4. Use Control+Alt+Backspace to terminate X server: <No>
      4. Change User Password (pi)
        pw.png
      5. Boot Options
        1. Desktop / CLI → Console Autologin
        2. Wait for Network at Boot → <No>
          • requires some action on network (re)connection → dhcpd hooks
      6. Interfacing Options
        • SSH → Enable

      1. <Finish> → reboot → <Yes>

            [ -f ~/.ssh/known_hosts ] && rm ~/.ssh/known_hosts
        clear logs
        • Before creating the next image,
          • Remove zipped files,
            clear all logs:, and
            history 
            sudo su -c '(find /var/log -name "*.gz" -delete && for item in $(find /var/log/ -type f | grep -v git-daemon | grep -E -v '\.1$' ); do sudo cat /dev/null > $item;  done && history -c )'
            history -c

      1. Power off:
        sudo poweroff
      2. Remove SD card and save the current image.

      Shrinking the Image

      • Think of Resizing
        • Why? : Since the complete size of the SD is stored as image, and sizes of SD cards vary, a resize - at least a few MB is recommended.

      docker 

      If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker your-user

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.
