- In this video, I'm gonna show you how
to run WSL version two on a Windows 10 laptop. I'm gonna show you how to install WSL and I'm gonna show you how to use the integration between Linux and Windows to do interesting things. WSL version two builds on the work done with WSL version one, but rather than using a translation layer between Linux and Windows, it uses virtualization technology to allow you to run
lightweight virtual machines directly on Windows 10. Gone are the days when Microsoft
said "Linux is a cancer," gone are the days when
Microsoft hated Linux. Microsoft have changed dramatically over the last few years. They've purchased GitHub, they do a lot of work in the cloud, and they now give you a Linux kernel directly within Windows. Yes, even though it's unbelievable, you get a Linux kernel
with Windows 10 these days. This makes it very easy to learn Linux, allows you to run a
Windows operating system, but still develop on Linux if you want to, very tight integration
between WSL version two and Windows 10. Let's get started. (electronic music) In this example, I'm using this Windows laptop. This Windows laptop is
running Windows Home Edition, it's not running Professional. You don't need the Professional version of Windows to do this. Home Edition is fine. As you can see here, Windows
edition, Windows 10 Home. Now there are some requirements. You need to have a later
release of Windows 10. If I run winversion, I can see
that I'm using version 2004. It's recommended that you
have at least that version, so OS Build 19041.246. You can see this on the
Windows 10 release information. Version 2004 was released
on the 27th of May 2020. Here's the operating system build. Once again, that's the
version that I'm running on this computer. I've basically updated this
computer to that version. It's recommended that you do the same. As always, go to your
Windows update settings, go to Windows update. Make sure that you've
updated your computer to at least this version of Windows 10. Once you've updated your Windows
computer to that release, it's fairly simple to enable this. You need to go to turn
Windows features on or off in Control Panel. I'm once again using Windows Home here, so I'm not going to enable
the Hypervisor Platform. All I'm gonna enable is the
Windows Subsystem for Linux and the Virtual Machine Platform. Make sure that you've enabled
both of those options, Windows Subsystem for Linux
and Virtual Machine Platform. Again, we're going to be
using a virtual machine here rather than a translation layer
between Linux and Windows. Much better in WSL version two. Click okay. Windows searches for the required files and then applies the changes. What you will need to do
now is reboot your computer, so click restart now to
restart your Windows computer. Windows updates are installed
and the computer's rebooted. Once the computer has rebooted, go to the Windows Store
and search for Ubuntu. Ubuntu released 20.04 LTS in April 2020, so I'm gonna get that
latest release of Ubuntu. I've already downloaded this,
so it displays as install. If you haven't downloaded it previously, then click download and once
you've clicked download, click install to install
this on your computer. It's about 432 Megan size. Once it's downloaded, click
launch and as you can see, it says installing, this
may take a few minutes. I'm getting an error saying this requires a kernel component. I need to go to this URL to get an update, so I'm gonna go to that URL. I'm told that I need to download the latest WSL two Linux kernel update package for
64-bit operating systems. I've already downloaded that,
but I'll download it again. It's only 13 Megan size. In my downloads already, this is the file that I've downloaded, so I'll double-click
on that and click run. I'm told that the setup wizard will install the Windows Subsystem for Linux update on my computer. Click next to continue,
so I'll click next, click yes to install the
software and click finish. Now that that's been done, I'll press any key to continue and I'll click launch again
to install the software. I'm told installing this
may take a few minutes. I'm told please create a
default UNIX user account. The username does not need to
match your Windows username, so I'm gonna create a username of David and I'll set a password
and I'll press enter. I'm told that installation is successful. To run a command as administrator, use the sudo command and I'm told welcome to Ubuntu 20.04 LTS. Notice the Linux version 4.19.104 Microsoft Standard Edition x86 64-bit. LS as an example shows me
that there are no files, PWD shows me the directory I'm in. I can go to root as an example, so PWD LS shows me the files here. As you can see, I'm running Linux. I'll type exit now to exit out of that. What I've basically done
now is installed Linux on this computer. If I wanted to start that again, I can type Ubuntu and run Ubuntu and notice in a matter of a few seconds, I've got an Ubuntu shell
running on my computer. What I'll do is open up PowerShell. This is PowerShell. It's not a Linux terminal, but I've got a Linux
terminal in the background. Make this a bit bigger. I've got a Windows PowerShell
and a Linux terminal. I can use the command WSL-L-V to see the version of the
machines that I'm running. In this example, I'm running version two. If your Linux VM is running version one, you can use the command
WSL--set version Ubuntu, or whatever the name of
the virtual machine is, two and this will make it use version two. You could set it back to
version one if you wanted to, but I'm gonna leave that at version two. You can also make version two the default by saying WSL--set default version two, and that'll make it
version two by default. Your output may vary slightly to what I'm showing you here because I've already set mine to version
two, but as an example, let's set that Ubuntu to version one. You can see the Linux shell closed. The conversion process is taking place now and while I'm waiting for that, let's get Ubuntu 18.04 LTS. I'll click get to get 18.04,
so an older version of Ubuntu, and that's now downloading. Today, it's recommended that
you use WSL version two. It's a lot more optimized,
runs a lot quicker, it's using virtualization technology, but you could use version
one if you wanted to. Version 18.04 has been installed. I'll click launch to launch 18.04. I'm gonna specify a Linux name once again, put a password in, and as you can see, I'm now using 18.04. I'll use LSB release actually
so we can see the release. You can see that this
version is 18.04 Ubuntu. Going back to my 20.04 WSL, L version shows me that 18.04 is running, it's using version two,
20.04 has been stopped, it's using version one, but I'll set it back to version two. I'd rather have everything
running as version two. 18.04 started as version two because I set WSL version two as the default, but I'll close this down, I'll
open up another PowerShell, WSL-L-version. This is being converted, this
is running at the moment, so to start Ubuntu, simply search for the Ubuntu
that I wanna use, so 18.04, and there you go. LSB release-A. I've got 18.04 running. Once the conversion has
completed, I'll start 20.04. The version has completed. WSL-L, you can see we've got
two Linux distributions, -L-V. We can see that Ubuntu 20.04 has stopped, it's using version two again, 18.04 is running using version two. You probably don't wanna jump from one version to the other
like I've shown you here. I just wanted to show you the commands. You probably wanna stick with version two if that's the version
that you're starting with. Again, I could start Ubuntu 20.04. Here's 20.04. I'll make the size of
this window a bit bigger, so let's go 20. I've got two windows now. Again, LSB_release-A
shows me that I'm running Ubuntu 18.04 here. On this window, LSB_release-A, I'm running Ubuntu 20.04 and
here, I'm running Windows. Notice the prompt here is a
Windows prompt whereas here, I've got Linux prompts. Let's make these windows a bit bigger. I've got Ubuntu 18.04,
Ubuntu 20.04, and Windows 10 all running on the same computer. I can shut these down. Notice they're still running. If I just type WSL, I'm running directly within Ubuntu 20.04. If I exit out of there, I'm back on Windows again so
I can use command such as DRR, I can also use the command
WSL--help to see help. As you can see here, I've got the shutdown
command to WSL--shutdown and then if I look at
all my versions again, notice they both shut down. Both 20.04 as well as 18.04 shut down, but notice I could simply
start Ubuntu 20.04 this way. It's already booted,
so back in PowerShell, I can see 20.04 is
running, 18.04 has stopped. I've got an Ubuntu shell here once again. It took only a few seconds to boot up. That's much quicker than using VMware Workstation Player as an example. And that being said, it's now possible with the latest release of VMware Workstation Player
to run WSL version two and VMware Player at the same time. However, I have found that it doesn't work if you wanna use nested virtualization. This virtual machine requires
nested virtualization and in this case, I have
problems starting the virtual machine up. If you want to run a virtual machine let's say Kali or Kali Linux here, it's possible to boot
this up at the same time as running in WSL, but I have found that
it gives me problems, so after this point, I wouldn't be comfortable running VMware Workstation Player
at the same time as WSL. You might find that it runs really slowly, but it is possible to
run these two together. Notice I've got Kali or Kali booted up and I've got Ubuntu
20.04 running within WSL, so WSL-L-V, I've got Ubuntu 20.04 running as we can see over here and I've got Kali or Kali Linux
running at the same time, so LSB release-A. I'll zoom in a bit here
to make it easier to see, but notice I've got once
again, LSB_release-A, this is Kali or Kali Linux 20.01 and I've got Ubuntu 20.04
running at the same time on a Windows 10 Home computer. Personally, I wouldn't run
VMware Workstation Player or VMware Workstation Pro or
VirtualBox at the same time as WSL because nested
virtualization does not support it. I find that it runs slowly. You're probably gonna wanna stick with VMware Workstation
Player or VirtualBox if you wanna boot up VM's, but the great thing about WSL is there's very tight integration
between Windows and WSL and if you wanna get
your feet wet so to say or if you wanna start learning Linux, this is a great way to get started. One of the advantages of WSL version two is it boots up really quickly. You could also compile a lot quicker. It's a lot quicker than WSL version one. It's much quicker to
boot up a shell like this than it is to try and boot
up the virtual machine, but there's also tight integration between Windows and Linux. If I type code dot, what I'm doing is starting
the Visual Studio Code, which is a Windows application, and notice I'm told that the remote WSL extension is recommended as you have WSL installed on your system and I'm gonna click install to install that. What it's gonna allow me to do now is open any folder within
Visual Studio Code. I'll run that again. The VS Code server for X86
is downloaded and installed and notice now, I'm able
to create code within Visual Studio Code, but
on the Linux Subsystem. Notice I can see my bash history. I'm basically working
on the Ubuntu system. If I go file and new file, and I'll paste some Python code here, make that a bit bigger, this will allow me to
SSH to a Cisco switch running on the internet. I'm gonna click save
and I'm gonna call this xe.py and click okay. This is a Python script once again. On my Linux Subsystem, type LS. Notice I've got a file called xe.py. I could run this by using
the command python3 xe.py. Now I'm told that
netniko is not available, so first thing, is Python installed? Python version two is not installed, but Python version three
is installed by default on my Linux Subsystem. I'll just minimize that so we
can see the screen clearly. I've got Python three, but I need to install
this module, netniko, to be able to use this command. I'm gonna run pip3. That's not currently installed, so I'm told I can use sudo
apt install python3-pip. I'm told that that doesn't exist, so let's do sudo apt update
to update my references. As you can see, these are
proper Linux commands. Then let's install python pip three, so that went quickly. Just to show you the command, I ran this command sudo
apt install python3-pip, I'm gonna say yes to install it. That's busy installing. There you go, it's installed, so I'll say sudo pip3 install-u
netmiko to install netmiko. Netmiko is now installed,
so I'll clear the screen. Once again, we wanna run this application, so on Linux, python3
xe.py, a Python script. This should connect to a Cisco router on the internet and pull back information such as the interfaces on
the router, and there you go, and that came from this command. This is a command that I'm sending to a Cisco switch actually, not a router, and pulling back at the information. That shows us the output of a command, but to show the integration, I could use a command
here such as show IP route and what I'll do is click file, save, and then back in Linux,
if I type cat xe.py, notice the file has changed
and if I run that again, the output will be different here. Here's the output. I'm running the script in Linux, but I'm editing it from within Windows. There's very tight integration between the Linux subsystem and the
Windows operating system. That was a quick overview of
WSL running within Windows 10. I hope you enjoyed this video. If you did, please consider subscribing to my YouTube channel,
