史上最全从0开始教你玩转wsl2+docker,构建自己的开发环境

1、安装wsl

需要windows版本大于

d7bf687a3c3a654b7fee10568ea538d8.png

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

e4d4b9658f4b42bb8752ca84d75377e4.png

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. See# sshd_config(5) for more information.# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin# The strategy used for options in the default sshd_config shipped with# OpenSSH is to specify options with their default value where# possible, but leave them commented.

重启ssh项目

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

7eb77bd241f1493489c332a98338c274.png

勾选你安装的ubnutu

 

cdc0ac2185c94feeb72548e0fb98572a.png

 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"
