我的 Raspberry Pi Zero 2W 折腾笔记,记录一些遇到的问题和解决办法

本文主要是介绍我的 Raspberry Pi Zero 2W 折腾笔记,记录一些遇到的问题和解决办法,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

0x00 前言说明

最近买了一块Raspberry Pi Zero 2W来玩,目的是想搭建一台远程运行的个人服务器,上面放个博客、点个灯啥的。于是就有了这篇文章。

树莓派官网地址:https://www.raspberrypi.com/

0x01 SSH连接

首先一开始买到手之后我是很懵的,于是在google上找到了以下几篇文章帮助了我很多。

  • https://www.freesion.com/article/3840979679/
  • https://www.cnblogs.com/liaouser/p/15844159.html
  • https://www.freebuf.com/geek/209255.html
  • https://shumeipai.nxez.com/2018/02/20/raspberry-pi-zero-usb-ethernet-gadget-tutorial.html?variant=zh-cn
  • https://www.youtube.com/watch?v=sUU-ch8LEcE&ab_channel=ITCommander

看了那个youtube上面的视频后,发现其实买之前是可以叫淘宝客服帮忙焊接gpio引脚的。然后发现我身边有一个电烙铁,于是打算试一下(从来焊接过),结局如下

image

还好,没有坏掉!哈哈,这就是不看教程就直接动手的后果,望大家引以为戒!那么,跟着上面的教程写入操作系统到sd卡之后就是安装驱动和ssh连接树莓派了,连接的时候遇到了一个问题就是pi@raspberrypi.local's password,ssh登录不上去,看了下官方发现:

There are also mechanisms to preconfigure an image without using Imager. To set up a user on first boot and bypass the wizard completely, create a file called userconf or userconf.txt in the boot partition of the SD card; this is the part of the SD card which can be seen when it is mounted in a Windows or MacOS computer.

This file should contain a single line of text, consisting of username:encrypted- password – so your desired username, followed immediately by a colon, followed immediately by an encrypted representation of the password you want to use.

To generate the encrypted password, the easiest way is to use OpenSSL on a Raspberry Pi that is already running – open a terminal window and enter

echo 'mypassword' | openssl passwd -6 -stdin
This will produce what looks like a string of random characters, which is actually an encrypted version of the supplied password.

简单来说就是树莓派为了安全起见不在使用默认密码,所以需要在启动前在boot目录下创建一个userconf.txt,格式如下:

username:encrypted-password

其中encrypted-password可以用echo 'mypassword' | openssl passwd -6 -stdin这条命令生成,贴一下我生成的配置:

pi:$6$T12E4motTbeG7HXC$0vvzm.7sNj9bsEzVL2JT4P9OYXpvsk3lwqK6CzTVyyLrRdUA.fZVWrfzqmU./mmuU1O/i3xSueXPX4ieBjrCM/

也就是用户名为pi,密码为raspberry。重新写入sd卡之后,再次连接一波!

λ ssh pi@raspberrypi.local -p 22
