============================

Wsl Ubuntu的IP地址会随着宿主机Windows的重启而更换IP，为此会对远程ssh连接造成一定的麻烦，为此考虑对其设置固定IP。

给出windows宿主机上的命令操作：

wsl.bat 文件，内容如下，运行该脚本后 WSL Ubuntu Ip: 172.18.54.10, Windows 宿主机IP：172.18.54.1

@ECHO OFF
%1 mshta vbscript:CreateObject("Shell.Application").ShellExecute("cmd.exe","/c ""%~s0"" ::","","runas",1)(window.close)&&exit
setlocal enabledelayedexpansion
wsl --shutdown ubuntu
wsl -u root service ssh start
if !errorlevel! equ 0 (
    wsl -u root ip addr | findstr "172.18.54.10" > nul
    if !errorlevel! equ 0 (
        echo wsl ip has set: 172.18.54.10
    ) else (
        wsl -u root ip addr add 172.18.54.10/16 broadcast 172.18.54.0 dev eth0 label eth0:1
        echo set wsl ip success: 172.18.54.10
    )
    ipconfig | findstr "172.18.54.1" > nul
    if !errorlevel! equ 0 (
        echo windows ip has set: 172.18.54.1
    ) else (
        netsh interface ip add address "vEthernet (WSL)" 172.18.54.1 255.255.0.0
        echo set windows ip success: 172.18.54.1
    )
)
ping 172.18.54.10
pause

给出的bat命令：（设置WSL ubuntu固定IP为192.168.120.181，宿主windows额外IP为192.168.120.100）

@echo off
setlocal enabledelayedexpansion

::不管三七二十一先停掉可能在跑的wsl实例
wsl --shutdown ubuntu
::重新拉起来，并且用root的身份，启动ssh服务和docker服务
wsl -u root service ssh start
wsl -u root service docker start | findstr "Starting Docker" > nul
if !errorlevel! equ 0 (
    echo docker start success
    :: 看看我要的IP在不在
    wsl -u root ip addr | findstr "192.168.120.181" > nul
    if !errorlevel! equ 0 (
        echo wsl ip has set
    ) else (
        ::不在的话给安排上
        wsl -u root ip addr add 192.168.120.181/24 broadcast 192.168.120.0 dev eth0 label eth0:1
        echo set wsl ip success: 192.168.120.181
    )


    ::windows作为wsl的宿主，在wsl的固定IP的同一网段也给安排另外一个IP
    ipconfig | findstr "192.168.120.100" > nul
    if !errorlevel! equ 0 (
        echo windows ip has set
    ) else (
        netsh interface ip add address "vEthernet (WSL)" 192.168.120.100 255.255.255.0
        echo set windows ip success: 192.168.120.100
    )
)
