| ===== What is WSL ? ===== | ===== What is WSL ? ===== |
| |
| Useful reading: | //Windows Subsystem for Linux// (**WSL**) lets you **run a Linux distribution on your Windows computer**, without the overhead of a traditional Virtual Machine (VM) or dual-boot setup |
| * Have a look at the beginning of the [[https://docs.microsoft.com/en-us/windows/wsl/about|Windows Subsystem for Linux Documentation]] for a quick **WSL** description on the Microsoft site | |
| * Read [[https://wiki.ubuntu.com/WSL|What is WSL]] on the Ubuntu site | |
| * There is more useful information on the //WSL@Ubuntu page//, you can read the rest later | |
| | |
| In a few words, WSL is not Linux, it's more a way to [[https://blogs.msdn.microsoft.com/wsl/2016/06/15/wsl-file-system-support/|share files between Windows and Linux]] (it's OK to skip this rather technical link!). [[https://docs.microsoft.com/en-us/windows/wsl/faq#are-files-in-the-linux-drive-different-from-the-mounted-windows-drive|Files under the Linux root (i.e. /) are controlled by WSL which mimics Linux specific behavior [...follow the link for details...]]]. That's why you need //to activate WSL **and then install a Linux distribution**//. | |

| | * [[https://wiki.ubuntu.com/WSL#What_is_WSL.3F|What is WSL?]] on the Ubuntu wiki site |
| ===== Prerequisites ===== | ===== Prerequisites ===== |
| |
| * A computer running at least //Windows 10 Anniversary Update//, that is with a version number of ''1607'' (July 2016) or higher | ==== Windows version ==== |
| * [[other:win10maintain#checking_the_installed_version|Check the installed version on your computer]] | |
| * [[other:win10misc#windows_10_versions|Check the available versions]] | * A computer running [[https://docs.microsoft.com/en-us/windows/wsl/install-manual#step-2---check-requirements-for-running-wsl-2|Windows 11 or Windows 10, Version 1903, Build 18362 or later]] |
| * [[other:win10maintain#updating_windows_10|See if you can update your Windows]] if your installed version is not the most receent available version | * [[other:win10maintain#checking_the_installed_version|Check the installed version on your computer]]\\ If you don't have the Windows version required for running WSL, you can: |
| * Note: there is sometimes a delay between the official release and the time when Windows Update will actually tell you that a major update is available for **your** computer (e.g. the //September YY09// update may become available for you only in December) | * [[other:win10misc#windows_10_versions|Check the available Windows versions]] |
| * //Enough// space on ''C:\''. Microsoft instructions say //The Windows Subsystem for Linux only runs on your system drive (usually this is your C: drive)// | * [[other:win10maintain#updating_windows_10|Check if you can update Windows]] |
| * Exporting a //simple// Ubuntu configuration (after doing everything from //Base installation// to //Advanced configuration// below) with the [[other:win10wsl#creating_a_backup_of_the_linux_running_in_wsl|wsl --export]] command generated a 2.7 Gb tar file (uncompressed), so it's probably good to **start with at least 3 Gb of free space on ''C:\''** (and you always need to keep enough free space on ''C:\'' for regular Windows operation) | |
| * The Linux ''/'' and ''/home'' partitions will always be on ''C:'', but the data files can be on any Windows disk/partition (or external drive) of the computer | |
| * the Windows partitions will be available and accessible in ''/mnt/'', so you can store data on other partitions (e.g. the content of the Windows ''D:\'' partition will be available in ''/mnt/d'' in Linux) | ==== The basics before starting ==== |
| * The files will be installed in **hidden partitions of the current user's directory on ''C:\''**: e.g. ''C:\Users\<your_login>''. Other users of the same Windows 10 computer would have to install Ubuntu again, in their own user directory | |
| * Checking the properties of ''C:\Users\<your_login>'' will **not** report an accurate size and number of files, because lots of files and directories are hidden! On the test laptop, the reported size of the user backed up directory (with [[other:win10apps#syncbackfree|SyncBackFree]]) was ~20 Gb (user data, WSL+Ubuntu, custom install of the CDAT 8.1 python distribution) | Once you have verified that your Windows is recent enough, you should also: |
| * Be sure to monitor the remaining free space on ''C:''! | |
| * Note: it seems that [[other:win10wsl#restoring_a_wsl_backup|wsl --import]] can restore a backed-up Linux to a user specified location. Maybe this can be used for moving Ubuntu... | * Install the [[other:win10apps#windows_terminal|Windows terminal]], because it will be one of the ways to open ''Ubuntu'' terminals, once ''Ubuntu'' is installed |
| * Check [[https://github.com/MicrosoftDocs/WSL/issues/412|how to move the vhdx of wsl2 to other disk]] and [[https://github.com/microsoft/WSL/issues/4320|[WSL 2] move VHD File]] for relocating a WSL (1 or 2) installation if you don't have enough space on ''C:'' | * Know how to use copy-paste in a Powershell FIXME |
| | * It will be useful to be able to [[other:win10config#displaying_hidden_folders_and_files_and_the_files_extension|see hidden folders and files]] |
| | * Have at least some basic knowledge of Linux... |
| | * Get some [[other:newppl:starting#useful_documentation_for_beginners|basic Linux documentation]] if required |
| | ==== Computer CPU and memory ==== |
| | |
| | Contrary to other virtual machines, WSL is well integrated with the Windows operating system and the hardware drivers and has a **low default CPU and memory footprint**! |
| | |
| | * You should be able to //play// with WSL even with 8 Gb of RAM, but 16 Gb is recommended |
| | * Of course, depending on what you need to do on your computer, a better processor will always help |
| | * WSL+Ubuntu will use more CPU and RAM if you use it for running CPU and/or memory intensive processes! As would be the case with any Windows application... :-) |
| | |
| | |
| | ==== Disk usage ==== |
| | |
| | === Overview === |
| | |
| | * ''WSL'' is part of the Windows operating system and will be installed (and updated) on ''C:\'' |
| | * The Linux installation(s) will be installed (and updated) on ''C:\'' |
| | * They can only be relocated to other partitions afterwards |
| | |
| | * => We should **start with at least 10 Gb of free space on ''C:\''** (but more space is always better and safer) |
| | * The initial installation will not use much space (2-3 Gb), but we always need space on ''C:\'' for other applications and Windows maintenance (temporary files, updates, ...) |
| | |
| | <WRAP center round alert 60%> |
| | FIXME The rather technical //Disk usage// sections below should be moved somewhere else! |
| | </WRAP> |
| | |
| | |
| | === How does it work? === |
| | |
| | WSL+Linux seems to use a combination of actual Windows files/folders and ''ext4'' Linux partitions stored in ''.vhdx'' ([[https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-vhdx/83f6b700-6216-40f0-aa99-9fcb421206e2|Dynamic Virtual Hard Disk]]) files. The Linux disk (of type ''ext4'') is stored in a single ''some_name.vhdx'' Windows file that will automatically grow until it reaches a predefined maximum size of 256 Gb (if there is enough space on the Windows disk...) |
| | |
| | * Check [[https://docs.microsoft.com/en-us/windows/wsl/vhd-size|Expand the size of your WSL 2 Virtual Hard Disk]] if you need more than 256 Gb |
| | * Check the following threads if you want to reduce the size of the ''vhdx'' file: |
| | * [[https://superuser.com/questions/1606213/how-do-i-get-back-unused-disk-space-from-ubuntu-on-wsl2|How do I get back unused disk space from ubuntu on wsl2?]] |
| | * [[https://github.com/microsoft/WSL/issues/4699#issuecomment-1136319012|WSL 2 should automatically release disk space back to the host OS]] |
| | * [[https://docs.microsoft.com/en-us/powershell/module/hyper-v/optimize-vhd?view=windowsserver2019-ps|Optimize-VHD]] |
| | |
| | === Disks seen from Linux === |
| | |
| | The disks and partitions usage, as seen from Linux, can be displayed with ''df -h'' |
| | |
| | <code>stdu@sadira034:~$ df -h |
| | Filesystem Size Used Avail Use% Mounted on |
| | /dev/sdb 251G 1.5G 237G 1% / |
| | tmpfs 6.2G 0 6.2G 0% /mnt/wsl |
| | tools 472G 118G 355G 25% /init |
| | none 6.2G 0 6.2G 0% /dev |
| | none 6.2G 8.0K 6.2G 1% /run |
| | none 6.2G 0 6.2G 0% /run/lock |
| | none 6.2G 0 6.2G 0% /run/shm |
| | none 6.2G 0 6.2G 0% /run/user |
| | tmpfs 6.2G 0 6.2G 0% /sys/fs/cgroup |
| | drivers 472G 118G 355G 25% /usr/lib/wsl/drivers |
| | lib 472G 118G 355G 25% /usr/lib/wsl/lib |
| | C:\ 472G 118G 355G 25% /mnt/c |
| | D:\ 480G 2.6G 478G 1% /mnt/d</code> |
| | |
| | * The ''251G'' //Size// of ''/'' depends on the [[https://docs.microsoft.com/en-us/windows/wsl/vhd-size|256G default size]] of the growing virtual disk where Linux is installed |
| | * The ''/mnt/c'' and ''/mnt/d'' are the way to access the Windows ''C:'' and ''D:'' disks from Linux, and their //Size// is the actual size of the Windows disks |
| | * Some //Filesystems// like ''drivers'' are actually Windows file systems! |
| | * <code>stdu@sadira034:/usr/lib/wsl/drivers$ du -sh /usr/lib/wsl/drivers |
| | 9.1G /usr/lib/wsl/drivers |
| | |
| | stdu@sadira034:/usr/lib/wsl/drivers$ du -sh /mnt/c/Windows/System32/DriverStore/ |
| | 9.1G /mnt/c/Windows/System32/DriverStore/</code> |
| | |
| | |
| | === Some important disk locations === |
| | |
| | * Accessing **Windows files from Linux**: ''/mnt/''\\ e.g ''C:\'' is available in ''/mnt/c'' |
| | |
| | * Accessing **Linux files from the Windows Explorer**: ''\\wsl$'' |
| | |
| | * WSL+Ubuntu installation: |
| | * Main directory: ''C:\Users\your_login\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc'' |
| | * //vhdx// file: ''C:\Users\jypeter\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\ext4.vhdx'' |
| | * <code>stdu@sadira034:~$ ls -lh /mnt/c/Users/jypeter/AppData/Local/Packages/CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc/LocalState/ext4.vhdx |
| | -rwxrwxrwx 1 root root 1.2G Aug 24 15:20 /mnt/c/Users/jypeter/AppData/Local/Packages/CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc/LocalState/ext4.vhdx</code> |
| | |
| | * Linux //swap// (virtual memory) file: |
| | * <code>stdu@sadira034:~$ ls -lh /mnt/c/Users/jypeter/AppData/Local/Temp/swap.vhdx |
| | -rwxrwxrwx 1 root root 63M Aug 24 14:52 /mnt/c/Users/jypeter/AppData/Local/Temp/swap.vhdx</code> |
| | |
| | |
| | === Sample disk usage === |
| | |
| | * Disk size after the initial installation of //Ubuntu 20.04 LTS//\\ ''-rwxrwxrwx 1 root root 1.2G Aug 24 15:20 /mnt/c/Users/jypeter/AppData/Local/Packages/CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc/LocalState/ext4.vhdx'' |
| | |
| | * Disk size after upgrading to //Ubuntu 20.04.4 LTS// with ''sudo apt update && sudo apt upgrade''\\ ''-rwxrwxrwx 1 root root 2.6G Aug 24 15:24 /mnt/c/Users/jypeter/AppData/Local/Packages/CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc/LocalState/ext4.vhdx'' |
| | |
| | ==== Hyper-V requirements ==== |
| | |
| | WSL 2 needs the //Virtual Machine Platform// to be enabled on your computer. If you have never used WSL before, you can probably go directly to the [[other:win10wsl#base_installation|Base installation]] section and ''wsl'' should install everything correctly |
| | |
| | If you have problems, or if you are updating WSL 1 to WSL 2, use ''systeminfo'' to check the [[https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/hyper-v-requirements?source=recommendations#verify-hardware-compatibility|Hyper-V requirements]] |
| | |
| | If you get a ''No'' for one of the ''Hyper-V requirements'', check the //virtualization// settings in your [[other:bios#entering_the_bios|computer BIOS]] |

| |
| * Follow **closely** the steps listed in [[https://docs.microsoft.com/en-us/windows/wsl/install-win10|WSL Windows 10 Installation Guide]]. <wrap hi>Open this [[https://docs.microsoft.com/en-us/windows/wsl/install-win10|WSL Windows 10 Installation Guide]] in another window, so that you can **read the useful hints below at the same time!**</wrap> | * The steps below (based on [[https://docs.microsoft.com/en-us/windows/wsl/install|Install Linux on Windows with WSL]]) will work if you have //Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11// |
| * When you have to //Open PowerShell as Administrator//, go to ''Start''=>''W''=>''Windows PowerShell'' then right-clik on ''Windows PowerShell'' and select //Run as Administrator// | * If you have an older Windows version (at least //Version 1903, Build 18362//), follow the [[https://docs.microsoft.com/en-us/windows/wsl/install-manual|Manual installation steps for older versions of WSL]] |
| * FIXME At this stage, we could try to restore/clone a previously installed/customized/backed-up version of Ubuntu if we have one (see [[other:win10wsl#restoring_a_wsl_backup|Restoring a WSL backup]]) | |
| * In the //Install your Linux Distribution of Choice//, we will use the very easy //install from the Microsoft Store// option | * Open a ''Powershell'' in //administrator// mode |
| * Open the **Microsoft Store** with: ''Start''=>''Microsoft Store'' | * ''Start''=>''W''=>''Windows PowerShell'' then right-click on ''Windows PowerShell'' and select //Run as Administrator// |
| * In the **Microsoft Store**, just search //Linux// and select the //generic// **Ubuntu** (select the //Ubuntu// that has **no version number after the name**) | * Use a [[https://wiki.lsce.ipsl.fr/pmip3/doku.php/other:win10apps#windows_terminal|Windows Terminal]], if you have already installed it. Use ''CTRL''+<left click> on ''Windows Powershell'' in the pull-down menu to get a ''Powershell'' in //administrator// mode |
| * Select ''Get'' (''Télécharger'') to download the installer package. You can ignore (''No thanks'') the popups asking you to use a Microsoft account, if you are not using a Microsoft account yet on this machine | |
| * Select ''Launch'' (''Lancer'') to start the installation, and give a user name (e.g. your LSCE login) and password (something that you can remember, but maybe not the same password as your LSCE account) | * Determine which Linux distributions are (directly) available for installation.\\ We will use the default ''Ubuntu'' distribution |
| * Type some basic Linux commands to check that things are working, e.g. check the available disks\\ <code>$ df -h | * ''Ubuntu'' will always automatically upgrade to the latest ''LTS'' release available (contrary to ''Ubuntu-<even_number>.04'' that will stick to the specified ''<even-number>'' release) |
| | * We could specify a specific Linux version (or even [[https://docs.microsoft.com/en-us/windows/wsl/use-custom-distro|import any Linux distribution]], or [[https://docs.microsoft.com/en-us/windows/wsl/build-custom-distro|create a custom Linux distribution]]!) |

| | |
| | * Reboot the computer and be patient |
| | * This step will take some time (make sure you have 15-30 mn available). Windows will install and configure what it needs for running //WSL+Ubuntu//, reboot, and install some more //stuff// |
| | * The final installation step will take place when you open your Windows session. A terminal opens, displaying the final installation of Ubuntu, and asking you for a username and password, and giving you access to a ''bash'' prompt |

| | ==== Upgrading WSL 1 to WSL 2 ==== |
| | |
| | <WRAP center round tip 60%> |
| | You will be able to run existing WSL 1 installations with WSL 2, so upgrading should not be a problem! |
| | </WRAP> |
| | |
| | |
| | === Determining which version of WSL is installed ? === |
| | |
| | If you have never used WSL on a computer, WSL 2 will be installed directly when you follow the [[other:win10wsl#base_installation|Base installation]] steps |
| | |
| | You can determine if your installed Linux distributions are running on WSL 1 or WSL 2 by typing ''wsl -l -v'' in a PowerShell, but if you are not sure if you are currently using WSL 1 or WSL 2 for running Linux, you can check if [[https://github.com/MicrosoftDocs/WSL/issues/1599|Is there an easy (PowerShell?) way to get more information about WSL?]] has been answered, or make the following checks |
| | |
| | * ''wsl --update'' will give the same output (i.e. the installed Linux kernel version) for both WSL 1 and WSL 2 |
| | * <code>PS C:\Users\jypeter> wsl --update |
| | Recherche de mises à jour en cours... Veuillez patienter |
| | Aucune mise à jour n’est disponible. |
| | Version du noyau : 5.10.102.1</code> |
| | |
| | * ''wsl --status'' will display again the kernel version if you already have WSL 2, but **will display a link to the WSL installation page if you are running WSL 1**: https://aka.ms/wsl2-install |
| | * <code>PS C:\Users\jypeter> wsl --status |
| | Distribution par défaut : Ubuntu |
| | Version par défaut : 2 |
| | Activez la fonctionnalité Windows de plateforme de machine virtuelle et assurez-vous que la virtualisation est activée dans le BIOS. |
| | Pour plus d’informations, rendez-vous sur https://aka.ms/wsl2-install</code> |
| | |
| | |
| | === Prerequisites === |
| | |
| | * If WSL 1 is already running, you should have no problem with the [[other:win10wsl#prerequisites|disk and memory requirements]] |
| | * For WSL 2, you also need to meet the [[other:win10wsl#hyper-v_requirements|Hyper-V requirements]] |
| | |
| | === Updating! === |
| | |
| | |
| | [[https://docs.microsoft.com/en-us/windows/wsl/install-manual#step-3---enable-virtual-machine-feature|Activate the Virtual Machine Platform]] (just the //Step 3// instructions) and reboot the computer |
| | |
| | After rebooting, go back to the [[other:win10wsl#determining_which_version_of_wsl_is_installed|Am I using WSL 1 or WSL 2 ?]] section above, and check that you are now using WSL 2 |
