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/
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。
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
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 enterecho 'mypassword' | openssl passwd -6 -stdinThis will produce what looks like a string of random characters, which is actually an encrypted version of the supplied password.https://www.raspberrypi.com/news/raspberry-pi-bullseye-update-april-2022/
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！
