Headless Raspberry Pi Setup

发表于 | 分类于

Install

  1. Download “RASPBIAN JESSIE LITE” without PIXEL desktop.
  2. Unzip it to get the image file (.img) for writing to your SD card.

  3. Setup headless settings, if don’t have an extra keyboard or HDMI cable.

    1. Add “ssh” file to the SD card root. Then boot your Pi.
    2. Connect it to the router with wire. Then get its ip from the router.
    3. Use SSH to connect to your Pi.
      • ssh pi@<IP>, password: raspberry.
    4. Configure your Pi.
      • sudo raspi-config

    5. Setting WIFI up and reboot wireless.

      • sudo vi /etc/wpa_supplicant/wpa_supplicant.conf

            psk="password"
            priority=1
            id_str="home"
        }

      • sudo reboot

    6. Setting static ip.
      • ifconfig
      • sudo nano /etc/dhcpcd.conf

        interface wlan0
        static ip_address = 192.168.1.121/24
        static routers = 192.168.1.9

  4. Writing the image to the SD card, see the guide for your system:
