WSL2 固定IP

1. 网桥配置固定ip

这种模式不稳定，wsl经常崩溃

@echo off
setlocal enabledelayedexpansion
::先停掉可能在跑的wsl实例
wsl --shutdown ubuntu
if !errorlevel! equ 0 (
    ::检查WSL有没有我需要的IP
    wsl -u root ip addr | findstr "192.168.3.100" > nul
    if !errorlevel! equ 0 (
        echo wsl ip has set
    ) else (
        ::IP不存在则绑定IP
        wsl -u root ip addr add 192.168.3.100/24 broadcast 192.168.3.255 dev eth0 label eth0:1
        echo set wsl ip success: 192.168.3.100
    )
    ::检查宿主机有没有我需要的IP
    ipconfig | findstr "192.168.3.200" > nul
    if !errorlevel! equ 0 (
        echo windows ip has set
    ) else (
        ::IP不存在则绑定IP
        netsh interface ip add address "vEthernet (WSL)" 192.168.3.200 255.255.255.0
        echo set windows ip success: 192.168.3.200
    )
)
 ::为主机设置SSH转发端口
 netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=22 connectaddress=192.168.3.100 connectport=22

pause

wsl无法ping通windows

New-NetFirewallRule -DisplayName "WSL" -Direction Inbound  -InterfaceAlias "vEthernet (WSL)"  -Action Allow

允许wsl通过防火墙

2.另一种模式，自动配置wsl2 host

WSL2 启动时会自动变换IP，IP地址不可固定。使用Localhost有时候可以连接上去，有时候连接不上去。现在设置一个固定的host来配置WSL2

1. 配置Linux 获取IP启动脚本

如果无法写入，则需要在windows配置etc目录的权限，更改所属组，让User也有写入权

cd /etc
touch initWsl.sh
chmod 775 initWsl.sh
chmod 777 /mnt/c/Windows/System32/drivers/etc/hosts
vim initWsl.sh

initWsl.bash

#! /bin/sh

# 启动对应服务
#service ssh ${1}
#service docker ${1}

# 设置本地Wsl2域名，默认为wsl2host
ipaddr=$(ip -4 addr show dev eth0 | egrep 'inet ([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})' | awk '{print $2}' | awk -F/ '{print $1}')
hostName='wsl.local'
sed -i "/${hostName}/d" /mnt/c/Windows/System32/drivers/etc/hosts
echo "${ipaddr} ${hostName}" >> /mnt/c/Windows/System32/drivers/etc/hosts

sed -i "/${hostName}/d" /etc/hosts
echo "${ipaddr} ${hostName}" >> /etc/hosts

winip=$(cat /etc/resolv.conf | grep nameserver | awk '{ print $2 }')
winhost='win.local'

sed -i "/${winhost}/d" /etc/hosts
echo "${winip} ${winhost}" >> /etc/hosts

./initWsl.sh start

2. 配置Windows 启动运行脚本

进入 C:\Users\hanli\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
创建Ubuntu.vbs

Set ws = CreateObject("Wscript.Shell")
ws.run "wsl -d Ubuntu -u root /etc/initWsl.sh start", vbhide

执行Ubuntu.vbs

3. 通过localhost访问

curl localhost:port

即可访问到wsl2的端口
