ติดตั้ง WSL 2

Prerequisites

You must be running Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11.

Install WSL command

You can now install everything you need to run Windows Subsystem for Linux (WSL) by entering this command in an administrator PowerShell or Windows Command Prompt and then restarting your machine.

wsl --install

This command will enable the required optional components, download the latest Linux kernel, set WSL 2 as your default, and install a Linux distribution for you (Ubuntu by default, see below to change this).

The first time you launch a newly installed Linux distribution, a console window will open and you’ll be asked to wait for files to de-compress and be stored on your machine. All future launches should take less than a second.

Basic commands for WSL

Install a specific Linux distribution

wsl --install --distribution <Distribution Name>

Designate a distribution of Linux for installation besides the default (Ubuntu) by replacing <Distribution Name> with the name of the distribution. This command can also be entered as: wsl -d <Distribution Name>.

List available Linux distributions

> wsl --list --online
The following is a list of valid distributions that can be installed.
The default distribution is denoted by '*'.
Install using 'wsl --install -d <Distro>'.

  NAME            FRIENDLY NAME
* Ubuntu          Ubuntu
  Debian          Debian GNU/Linux
  kali-linux      Kali Linux Rolling
  openSUSE-42     openSUSE Leap 42
  SLES-12         SUSE Linux Enterprise Server v12
  Ubuntu-16.04    Ubuntu 16.04 LTS
  Ubuntu-18.04    Ubuntu 18.04 LTS
  Ubuntu-20.04    Ubuntu 20.04 LTS

See a list of the Linux distributions available through the online store. This command can also be entered as: wsl -l -o.

List installed Linux distributions

> wsl --list --verbose
  NAME      STATE           VERSION
* Ubuntu    Running         2

See a list of the Linux distributions installed on your Windows machine, including the state (whether the distribution is running or stopped) and the version of WSL running the distribution (WSL 1 or WSL 2). Comparing WSL 1 and WSL 2. This command can also be entered as: wsl -l -v. Additional options that can be used with the list command include: --all to list all distributions, --running to list only distributions that are currently running, or --quiet to only show distribution names.

Check WSL status

> wsl --status
Default Distribution: Ubuntu
Default Version: 2

Windows Subsystem for Linux was last updated on 15-Jul-22
The Windows Subsystem for Linux kernel can be manually updated with 'wsl --update', but automatic updates cannot occur due to your system settings.
To receive automatic kernel updates, please enable the Windows Update setting: 'Receive updates for other Microsoft products when you update Windows'.
For more information please visit https://aka.ms/wsl2kernel.

Kernel version: 5.10.16

See general information about your WSL configuration, such as default distribution type, default distribution, and kernel version.

Update WSL

wsl --update

Manually update the version of your WSL Linux kernel. You can also use the command: wsl --update rollback to rollback to a previous version of the WSL Linux kernel.

Shutdown

wsl --shutdown

Immediately terminates all running distributions and the WSL 2 lightweight utility virtual machine. This command may be necessary in instances that require you to restart the WSL 2 virtual machine environment, such as changing memory usage limits or making a change to your .wslconfig file.

Terminate

wsl --terminate <Distribution Name>

To terminate the specified distribution, or stop it from running, replace <Distribution Name> with the name of the targeted distribution.

ขั้นตอนการติดตั้ง WSL 2 สำหรับ Windows 10 ที่ Build ต่ำกว่า 19041

1.update Windows ให้เป็นเวอร์ชันล่าสุด (1909) , ตรวจสอบเวอร์ชันด้วยคำสั่ง winver

2.เปิด Windows Insider Program Settings แล้วเลือก Fast

3.เปิด Turn Windows features on or off เลือก Windows Subsystem for Linux และ Virtual Machine Platform

4.เปิด Microsoft Store เลือกติดตั้ง Ubuntu 18.04

หลังจากติดตั้งเสร็จ จะให้เราตั้ง username และ password

5.เปิด Power Shell

list ดู Distro ที่ติดตั้ง

> wsl -l
Windows Subsystem for Linux Distributions:
Ubuntu-18.04 (Default)

กำหนดให้ Ubuntu-18.04 ที่พึ่งติดตั้ง ใช้ WSL 2

> wsl --set-version Ubuntu-18.04 2

กำหนดให้ default เป็นเวอร์ชัน 2 เลย

> wsl --set-default-version 2

ตรวจสอบดูว่าเป็น version 2 แล้วหรือยัง

> wsl -l -v
  NAME            STATE           VERSION
* Ubuntu-18.04    Stopped         2

ถ้ารันแล้วไม่เจอคำสั่ง -v แสดงว่ายังเป็น WSL 1

6.กลับมาที่ app Ubuntu18.04 แล้วลองเรียก VS Code

> wsl -d Ubuntu-18.04

หรือ

$ code .
