Introducing Windows Subsystem for Linux WSL and Overview. Microsoft has been increasing their support of Linux across Azure public cloud, Hyper-V and Linux Integration Services (LIS) and Windows platforms including Windows Subsystem for Linux (WSL) as well as Server along with Docker support.

WSL installed with Ubuntu on Windows 10

WSL with Ubuntu installed and open in a window on one of my Windows 10 systems.

WSL is not a virtual machine (VM) running on Windows or Hyper-V, rather it is a subsystem that coexists next to win32 (read more about how it works and features, enhancements here). Once installed, WSL enables use of Linux bash shell along with familiar tools (find, grep, sed, awk, rsync among others) as well as services such as ssh, MySQL among others.

What this all means is that if you work with both Windows and Linux, you can do so on the same desktop, laptop, server or system using your preferred commands. For example in one window you can be using Powershell or traditional Windows commands and tools, while in another window working with grep, find and other tools eliminating the need to install things such as wingrep among others.

Installing WSL

Depending on which release of Windows desktop or server you are running, there are a couple of different install paths. Since my Windows 10 is the most recent release (e.g. 1709) I was able to simply go to the Microsoft Windows Store via desktop, search for Windows Linux, select the distribution, install and launch. Microsoft has some useful information for installing WSL on different Windows version here, as well as for Windows Servers here.

Get WSL from Windows Store

Get WSL from Windows Store or more information and options here.

Microsoft WSL install

Click on Get the app

Select which Linux for WSL to install

Select desired WSL distribution

SUSE linux for WSL

Lests select SUSE as I already have Ubuntu installed (I have both)

WSL installing SUSE

SUSE WSL in the process of downloading. Note SUSE needs an access code (free) that you get from https://www.suse.com/subscriptions/sles/developer/ while waiting for the download and install is a good time to get that code.

launching WSL on Windows 10

Launching WSL with SUSE, you will be prompted to enter the code mentioned above, if you do not have a code, get it here from SUSE.

completing install of WSL

The WSL installation is very straight forward, enter the SUSE code (Ubuntu did not need a code). Note the Ubuntu and SUSE WSL task bar icons circled bottom center.

Ubuntu and SUSE WSL on Windows 10

Provide a username for accessing the WSL bash shell along with password, confirm how root and sudo to be applied and that is it. Serious, the install for WSL at least with Windows 10 1709 is that fast and easy. Note in the above image, I have WSL with Ubuntu open in a window on the left, WSL with SUSE on the right, and their taskbar icons bottom center.

Windows WSL install error 0x8007007e

Enable Windows Subsystem for Linux Feature on Windows

If you get the above WSL error message 0x8007007e when installing WSL Ubuntu, SUSE or other shell distro, make sure to enable the Windows WSL feature if not already installed.

Windows WSL install error fix

One option is to install additional Windows features via settings or control panel. For example, Control panel -> Programs and features -> Turn Windows features on or off -> Check the box for Windows Subsystem for Linux

Another option is to install Windows subsystem feature via Powershell for example.

enable-windowsoptionalfeature -online  -featurename microsoft-windows-subsystem-linux

Using WSL

Once you have WSL installed, try something simple such as view your present directory:

pwd

Then look at the Windows C: drive location

ls /mnt/c -al

In case you did not notice the above, you can use Windows files and folders from the bash shell by placing /mnt in front of the device path. Note that you need to be case-sensitive such as User vs. user or Documents vs. documents.

As a further example, I needed to change several .htm, .html, .php and .xml files on a Windows system whose contents had not yet changed from https://storageio.com to https://storageio.com. Instead of installing wingrep or some tools, using WSL such as with Ubuntu finding files can be done with grep such as:

grep "https://storageio.com" /mnt/c/Users/*.xml

And then making changes using find and sed such as:

find /mnt/c/Users -name \*.xml -exec sed  -i "s,https://storageio.com,https://storageio.com,g" {} \;

Note that not all Linux apps and tools can use file via /mnt in which case a solution is to create a symbolic link.

For example:

ln -s "/mnt/c/Users/Test1/Documents"  /home/Test1/Projects

What This All Means

If you primarily work on (or have a preference for) Linux systems and need to do some functions from development to the administration or other activity on a Windows system, Windows Subsystem for Linux (WSL) provides a bash shell to do familiar tasks. Likewise, if you are primarily a Windows person and need to brush up on your Linux skills, WSL can help. If you need to run Linux server applications or workloads, put those into a Docker container, Hyper-V instance or Azure VM.

Overall I like WSL for what it is, a tool that eliminates the need of having to install several other tools to do common tasks, plus makes it easier to work across various Linux and Windows systems including bare metal, virtual and cloud-based. Now that you have been introduced to Windows Subsystems for Linux WSL and an overview including install as well as using, add it to your data infrastructure toolbox.

By the way, if you have not heard, its #Blogtober, check out some of the other blogs and posts occurring during October here.

Ok, nuff said, for now.

SDx Summit London UK (Planning and Enabling Your Journey to Software Defined)

Planning and Enabling Your Journey to Software Defined)

server storage I/O trends

Will 2017 be there year of all software-defined X (e.g. SDx) where X can be everything from data centers (SDDC), data infrastructures (SDDI), infrastructure (SDI), storage (SDS), network (SDN) or marketing (SDM) among others? What about IoT, IoD, ByoD, ByoL (bring your own license), MaaS (metal as a service), clouds, containers, object storage, OpenStack, Mesos, Docker, Kubernetes, NVMe, flash SSD, SCM (Storage Class Memory) among other buzzword bingo terms, technologies and trends, will 2017 be there year for those among others?

What is safe to say is that the above buzzword items, topics, trends, technologies, tools and techniques are in your future, what varies is when, where, how, why, with what and whom to assist you on your journey.

server storage I/O events

On January 26 2017 join me and others at the Savoy hotel in London UK for the SDx summit organized by Wipro.

My presentation titled Planning and Enabling Your Journey to SDx will have a theme of Transiting from Hype and Marketing Hope to Deployment and Management. In other words, moving beyond SDBS and SDM to how to prepare, plan and what you can do today including hybrid deployments. Some of the topics, themes, trends, technologies, tools and tips in my discussion will include among others:

  • Software Defined Management and Data Protection
  • How to pack and prepare for your Software Defined Journey
  • Be prepared, plan for the unexpected, manage your journey
  • Learn the local language, expand your trade craft (skills)
  • Moving and migrating (brownfield) vs. start from scratch (greenfield)
  • ByoD, DiY, IoD, IoT, Cloud and Container conversations
  • What you can do today to prepare for your upcoming journey

Where To Learn More

Learn more and register here for the London UK SDx summit.

What This All Means

Regardless of if 2017 will be the year of SDx or any of the other industry popular buzz term trends, technologies and techniques, it is time to start planning as well as preparing. This means identifying questions, concerns and learning about the new tools and technologies that can be used in new ways, while also leveraging old things in new ways to enable a resilient, scalable, flexible as well as cost-effective data infrastructure. For those of you in the London UK area, learn more about the SDx summit organized by Wipro here and hope to see you there.

Ok, nuff said, for now…
