樹莓派4 安裝 UbuntuServer20.04.1X64 位系統
01 準備資源
- 下載系統
https://ubuntu.com/download/raspberry-pi
Ubuntu Server 20.04.1 LTS 選擇樹莓派4 的 64bit 版本
https://cdimage.ubuntu.com/releases/20.04.1/release/ubuntu-20.04.1-preinstalled-server-arm64+raspi.img.xz
- 下載燒錄工具
從 https://www.raspberrypi.org/software/ 下載燒錄軟件 imager_1.5 。操作系統也可以在這個工具上面下載。
- 燒錄系統

- 安裝系統
把燒錄好的tf卡插入樹莓派4 tf卡槽內，網線連接路由。加電啓動。
02 系統初始化
# 查看樹莓派4的ip地址
arp -a | findstr dc-a6-32
# 192.168.31.229 dc-a6-32-e1-6b-7f 動態
# 或者從路由器上面查看樹莓派的ip地址
# 用終端連接查到的ip，並且修改ubuntu的密碼，初始化賬號密碼都是ubuntu
# 修改密碼後，用新密碼重新連接終端
# 查看系統信息
