1、安装wsl
需要windows版本大于
搜索启用或关闭windows功能
把图片中红点标注的功能勾选，注意勾选hyper-v就不能使用虚拟机类软件，如vm，安卓模拟器一类，点击确定，重启电脑。
打开任务管理器
确保虚拟化已经启用，部分设备可能需要去bios设置，自行查阅下相关资料
下载64位wsl2内核升级包 https%3A//wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi
安装后，设置默认wsl版本
wsl --set-default-version 2安装linux系统
方法一:可以从微软商店搜索安装，有概率会失败
方法二: 翻到页面最下方，下载你需要的版本 旧版 WSL 的手动安装步骤 | Microsoft Learn在旧版 Windows 上手动（而不是使用 wsl 安装命令）安装 WSL 的分步说明。
https://docs.microsoft.com/zh-cn/windows/wsl/install-manual给下载到的文件添加一个.zip后缀，用解压缩软件解压到你想安装的地方
点击里面的ubnutu.exe文件，等待一会就会安装成功
去cmd中输入 wsl -l -v 查看安装的子系统版本
2、安装完成后的设置：
安装完成后会设置自己的用户名，密码（注意不是root账户）
设置root密码
sudo passwd切换root用户测试
su root每次切换root用户很麻烦，可以用powershell执行下面这条命令，默认root用户登录，其中参数自己替换下
C:\Users\用户名\AppData\Local\Microsoft\WindowsApps\ubuntu版本.exe config --default-user root开启ssh服务
首先确保是root用户
vi /etc/ssh/sshd_config进入之后，修改如下配置，可以直接复制我的，（我修改的项加了注释）
#$OpenBSD: sshd_config,v 1.101 2017/03/14 07:19:07 djm Exp $# This is the sshd server system-wide configuration file.

sudo service ssh restart使用ssh工具测试链接
成功
3、windows下docker-desktop的安装
官网下载docker-desktop的安装包，一定要确保第一步开启的windows功能都开启了
Download Docker Desktop | Docker
正常软件安装流程
进入软件，点击小齿轮进入设置
勾选你安装的ubnutu
更改镜像仓库地址，我使用的阿里云，网上也有好多，比如中科大等
{ "debug": true, "experimental": false, "registry-mirrors": [ "https://lcuu39wt.mirror.aliyuncs.com" ]}resource中可以更改docker镜像位置，推荐更改，不然c盘会占用很高
设置完之后，打开终端，输入docker ps
就会发现docker和你的linux子系统已经连接起来了
4、配置wsl2新特性，一定要开，否则会出现内存泄漏，爆内存的情况
C:\Users\电脑用户名文件夹下新建一个.wslconfig文件
# Settings apply across all Linux distros running on WSL 2[wsl2]# Limits VM memory to use no more than 4 GB, this can be set as whole numbers using GB or MBmemory=8GB# Sets the VM to use two virtual processorsprocessors=8[experimental]autoMemoryReclaim=gradual # 开启自动回收内存，可在 gradual, dropcache, disabled 之间选择networkingMode=mirrored # 开启镜像网络dnsTunneling=true # 开启 DNS Tunnelingfirewall=true # 开启 Windows 防火墙autoProxy=true # 开启自动同步代理sparseVhd=true # 开启自动释放 WSL2 虚拟硬盘空间重启wsl2或重启电脑生效
5、存在的问题及解决思路
ssh服务不会自动开启
解决思路：
重启ssh服务的命令，根据需要修改参数哦，可以写个cmd脚本放在windows自启动文件夹中，开机自己运行就不用每次输入了
C:\Users\用户名\AppData\Local\Microsoft\WindowsApps\ubuntu2004.exe run "sudo service ssh restart"
