树莓派安装ubuntu server 20.10 笔记本+树莓派

前言

无外接键盘，显示器和网线，只用笔记本和树莓派

官网

1.树莓派各种支持的系统下载, ubuntu server 推荐Ubuntu Server 20.10https://ubuntu.com/download/raspberry-pi
2.ubuntu的官网安装树莓派的教程：https://ubuntu.com/tutorials/how-to-install-ubuntu-on-your-raspberry-pi#1-overview
node:我第一次选择的是Ubuntu Server 20.04.1 LTS（Raspberry Pi 4/ 64 bit）结果安装好后ssh连不上，permission denied,wifi也连不上 后来选用：Ubuntu Server 20.10（Raspberry Pi 4/ 64 bit）,直接配置好文件network-config就可以连接wifi了，ssh登录也可以。

准备条件

1. 笔记本
2. 树莓派
3. 路由器

只需要笔记本和树莓派在同一网络，获取到树莓派的IP,后面能用电脑ssh到树莓派系统

软件环境

1. Windows 10
2. Respberry Pi Imager
3. Fing 可选（手机端用于scan IP）
4. Advanced IP Scanner 可选(电脑端用于scan IP）

按照上面的步骤安装好后，找到respberry的IP地址，电脑端cmd进入
arp -a 查看局域网设备信息，找到类型是动态的Respberry 的IP
用ssh连接,cmd命令,如：ssh [email protected]
第一次登录，默认账号密码都是ubuntu，第一次连接要修改密码，修改成功后再次用新密码登录

相关截图代码

1. TF卡插入笔记本，修改system boot根目录下的文件：network-config
   设置wifi名称为:wifi-name
   密码：12345678

version: 2
ethernets:
  eth0:
    dhcp4: true
    optional: true
wifis:
  wlan0:
    dhcp4: true
    optional: true
    access-points:
      "wifi-name":
        password: "12345678"

找到RaspberryPi的IP地址

如果电脑和Raspberry在同一网络，根据网卡地址找IP
windows下cmd命令：arp -a | findstr dc-a6-32
返回的结果就是找到的RaspberryPi的IP和网卡地址
参考：
Connect remotely to your Raspberry PiTo connect to your Raspberry Pi remotely, you need two things (we’ll help you find them):
Its IP address on the local network
An SSH client (SSH is a communication protocol between machines)
Determining the Pi’s IP addressTo determine the IP address of your board, open a terminal and run the arp command:On Ubuntu and Mac OS:arp -na | grep -i “b8:27:eb”
If this doesn’t work and you are using the latest Raspberry Pi 4, instead run:arp -na | grep -i “dc:a6:32”

Information

Depending on your version of Ubuntu, you may need to install the net-tools package. Install it with sudo apt install net-tools and try the arp command again.
On Windows:arp -a | findstr b8-27-eb
If this doesn’t work and you are using the latest Raspberry Pi 4, instead run:arp -a | findstr dc-a6-32
