win10配置wsl：下载，盘迁移，镜像地址，ssh登陆

1. 安装

首先打开microsoft store,搜索ubuntu: 商店搜索
选择下载人数最多的 ubuntu
下面就可以开始摇摆了。没有别的需求本篇结束。

2. 系统迁移

由于wsl默认安装位置是系统盘，我的系统盘是一个256G的固态，容量比较珍贵，所以进行迁移，用这个工具：LxRunOffline,选择最新的工具进行下载。

迁移工具
下载完成后解压缩，在解压缩后的目录下打开power_shell（需要按住shift的同时右键）， 打开power_shell

• 打开后首先输入 .\LxRunOffline.exe list，检查当前有多少个linux版本： 检查版本
• 之后将wsl关闭：输入 wsl --shutdown 命令关闭当前运行的linux子系统。
• 之后进行迁移：.\LxRunOffline.exe move -n Ubuntu -d D:\Ubuntu，-d后面跟的是想要迁移到的位置，自己定义即可。命令输入后，会有一系列的warning，但是不需要管，等待程序静静执行完自己终止即可。 warning 完成后，输入.\LxRunOffline.exe get-dir -n Ubuntu即可看到目前系统已经迁移到的位置。 image.png

3 配置镜像源

wsl默认的镜像下载地址还是比较慢的，可以配置成阿里云的镜像，进入配置文件所在目录cd /etc/apt/，下面的sources.list文件就是存放镜像的地址，首先对其进行备份，只需要复制一份在当前目录下即可，不备份也无所谓。删除文件后新建一个同样名字的文件，将下面的地址拷贝进去：

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

# 预发布软件源，不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse                                                                                                   

4 配置ssh登陆

之前三步做完之后，如果你想通过ssh的方式登陆这台虚拟机，进行文件传输等工作的话，还需要有ssh服务，

• 首先卸载原有服务 ：sudo apt-get remove openssh-server
• 之后重新进行安装：sudo apt-get install openssh-server
• 之后进行配置：进入配置文件所在目录：cd /etc/ssh/，打开配置文件：sudo vim sshd_config，注意，要用sudo命令进行打开，否则没有修改权限，再次，要注意是sshd_config文件而不是ssh_config文件。
• 配置端口：Port 39000，默认是22，被占用。指定监听地址：ListenAddress 0.0.0.0，这个影响不大，用127.0.0.1或者本机ip地址都可以。将PasswordAuthentication yes密码登陆打开，root登陆禁止：PermitRootLogin yes,如果有不成功的可以用下面的配置文件：

#       $OpenBSD: sshd_config,v 1.103 2018/04/09 20:41:22 tj 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.  Uncommented options override the
# default value.

Include /etc/ssh/sshd_config.d/*.conf

Port 39000
#UsePrivilegeSeparation no
#AddressFamily any
ListenAddress 0.0.0.0
#ListenAddress ::

#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_ecdsa_key

#AuthorizedKeysFile     .ssh/authorized_keys .ssh/authorized_keys2

#AuthorizedPrincipalsFile none

#AuthorizedKeysCommand none
#AuthorizedKeysCommandUser nobody

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# HostbasedAuthentication
#IgnoreUserKnownHosts no
# Don't read the user's ~/.rhosts and ~/.shosts files
#IgnoreRhosts yes

# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication yes
#PermitEmptyPasswords no

# Change to yes to enable challenge-response passwords (beware issues with
# some PAM modules and threads)
ChallengeResponseAuthentication no

# Kerberos options
#KerberosAuthentication no
#KerberosOrLocalPasswd yes
#KerberosTicketCleanup yes
#KerberosGetAFSToken no

# GSSAPI options
#GSSAPIAuthentication no
#GSSAPICleanupCredentials yes
#GSSAPIStrictAcceptorCheck yes
#GSSAPIKeyExchange no

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM yes

#AllowAgentForwarding yes
#AllowTcpForwarding yes
#GatewayPorts no

#       ForceCommand cvs server

• 尝试一下，通过winscp进行文件传输： winscp连接 ，可以连接。或者用ssh -p 39000 你的user@localhost亦可尝试连接。
