How to install SQL Server on Linux hosted on Windows Server 2019

August 30, 2021 by

This article explores Windows Subsystem for Linux (WSL) to run the Linux operating system on Windows OS and configure SQL Server on Linux.


The Windows Subsystem for Linux (WSL) is a way for developers to run Linux directly on Windows 10 or Windows Server 2019 systems. Microsoft developed a Linux-compatible kernel interface for running Linux such as Ubuntu, RedHat, SUSE. Suppose you have a Windows Server 2019 server and you want to configure a SQL Server on Linux on it. Previously, you need to have a separate virtual machine for running SQL Server on Linux operating systems. Now, you can leverage WSL for this purpose with quick deployment.

  • You can download various Linux distributions from the Microsoft store
  • It allows you to run Bash shell scripts, Linux commands for JavaScript, Python, Ruby, C\C++
  • You can install additional software using the Linux distribution package managers
  • You can use tools such as vim, emacs or tmux on Windows

Introduction to Windows Subsystem for Linux (WSL 2) for SQL Server on Linux

Windows subsystem for Linux(WSL) 2 increases file system performance and system call capability for Linux on Windows OS. In the following screenshot from Microsoft docs, you get a glimpse of the WSL1, WSL2 comparison.

Comparison of WSL1 and WSL2

This article implements the following on an Oracle VirtualBox machine:

  • Deploy a Windows Server 2019 VM using the VHD file
  • Configure the Windows Subsystem for Linux
  • Install SQL Server on Linux ( Version 2019) on Linux OS
  • Connects and query SQL Database

Deploy a Windows Server 2019 VM using the VHD file

For this step, you require the Oracle VirtualBox application installed on your system. You can navigate to the URL https://www.virtualbox.org/ and download the latest version.

Download VirtualBox 6.1

Its installation is straightforward. However, you can refer to the article Steps to prepare a Virtual Machine for it. Once Oracle VM VirtualBox is installed, navigate to Try Windows Server 2019 on Microsoft Evaluation Center, and you get the following page to download Windows Server 2019 evaluation version. Here you get three options.

  • Azure: To configure Windows Server 2019 on Azure infrastructure
  • ISO: Download ISO file for Windows Server 2019
  • VHD: Download the Virtual hard disk (VHD) file for quick deployment

Download Windows Server 2019 ISO

  • Note: You can use the Windows Server2019 evaluation version for 180 days and be familiar with its features

This article uses the VHD file for quickly deploying. Click on VHD (Virtual Hard Disk) and download the file. Its size is approximately 8 GB.

Save ISO

Once Windows Server 2019 VHD file is downloaded, launch Oracle VM VirtualBox Manager and create New.

In the create the virtual machine, enter the following information:

  • VM name
  • VM machine folder
  • Memory (RAM) size
  • Hard disk: In the hard disk, select option – use an existing virtual hard disk file. Here, select the VHD file that you downloaded from Microsoft

Create a VM with VHD

Click on Create and start the virtual machine. It prepares the VM with the configurations in the VHD file.

Windows getting starting

In the process of getting ready, it asks for information for the keyboard layout. Further, accept the Microsoft software license terms.

Accept license terms

On the customize setting page, enter the password for the built-in administrator account.

Specify Windows administrator credentials

Click on finish, and your Windows Server 2019 server is ready for deployments.

Enable the Windows Subsystem for Linux for SQL Server on Linux

To run the Linux distributions on Windows Server 2019, we need to enable “Windows subsystems for Linux” from the Windows feature. You can enable it from Windows GUI or use the Windows PowerShell command.

To enable the feature from the graphical interface, launch Server Manager -> Manage -> Add Roles and Features and check on Windows subsystems for Linux as shown below.

Enable the Windows Subsystem for Linux for SQL Server on Linux

Click Next and follow the feature wizard to install WSL in GUI mode. Alternatively, open the Windows PowerShell in Administrator mode and run the following command.

It prompts you to enter Y before restarting the computer. It is a quick process for enabling the WSL feature and configuring it with virtual machine restart.

Enable feature using Windows PowerShell

Download a Linux distribution from the Microsoft store

You can download the following Linux distributions from the Microsoft store. To download it from the store, search for the specific distribution and click on Install to download and install it.

Alternatively, click on the distribution of your choice and download it on the virtual machine.

You can also download the Linux distribution from Windows PowerShell. The following query downloads the Ubuntu 16.04 using Windows PowerShell. It uses an Invoke-WebRequest for downloading the repository from the specified URL.

Download a Linux distribution

Once the Ubuntu distribution is completed, extract it using the expand-archive command.

Extract archive

Now, Browse to the Ubuntu directory and check the executable file name. For Ubuntu 16.04, the file name is ubuntu1604.exe.

Check Linux installation file

Execute the Ubuntu1604.exe, and it starts installation of Ubuntu 16.04 on Windows Server 2019. It takes a few minutes to install Ubuntu using WSL on Windows Server 2019.

Start Linux installation

Once you have installed the Linux distribution, it prompts you to specify credentials for the distribution default user. This account will get sudo (Super User do) access to perform the administrative activities. If you reset the Linux distribution WSL, you require to reset this account as well. You can create a different user for Unix from the local Windows user. For example, I have sqladmin user as a Windows administrator and linuxadmin as Unix administrator in my demo.

Once you enter the Unix user name and password, it configures the user and automatically sign-in to the Linux distribution.

For example, note the prompt – Linuxadmin@WIN-A96LOA99PE6. Here, Linuxadmin is the user and WIN- A96LOA99PE6 is the hostname.

Create a Linux administrator

Now, you can run Linux commands. For example, run ls-la to check directories.

Sample code

Install SQL Server on Linux (2019) on Windows subsystem Linux

We configured a Windows Server 2019 virtual machine and configured it for Windows Subsystem for Linux (WSL) in the previous step. Now, we will install SQL Server on Ubuntu OS.

Step 1: Import the public repository keys from the Microsoft package store

Run the following command in administrative Windows PowerShell.

Install SQL Server on Linux (2019)

Step 2: Register the Microsoft SQL Server 2019 Ubuntu repository

In this step, use add-apt-repository to register the repository for Microsoft SQL Server 2019 on Linux.

Add repository

Step 3: Install SQL Server

First, perform the apt repository update using the following command.

Update repository

Install SQL Server using apt-get command.

Install SQL Server

In the end, you get a prompt to install run the mssql-conf utility to perform the complete setup of Microsoft SQL Server.

Installation messages

SQL Server requires the following inputs for finishing the SQL Server configuration:

  • SQL Server edition
  • Accept license terms and conditions
  • Specify SQL Server administrator password

SQL Server edition

Provide the inputs, and your SQL Server is ready on Ubuntu Linux on Windows Server 2019.

License terms and specify SQL SA password

You can use SQL Server Management Studio, Azure Data Studio or SQLCMD utility to connect with SQL Server, create databases and execute queries.

If you are running Windows 10, you can follow the Microsoft docs for configuring SQL Server using the Window’s subsystem for Linux.

Reset Linux administrator password for Windows subsystems on SQL Server on Linux

Suppose you want to change the Linux administrator for Windows Server 2019 subsystem. For this purpose, run the passwd command in the administrative Windows PowerShell, specify a current and new password.

Change or reset Linux administrator password


In this article, we learned about utilizing the Windows subsystem for Linux that can configure Linux on the Windows operating system. You do not require a separate virtual machine for running Linux commands and utilities. You can run SQL and NoSQL databases MySQL, PostgreSQL, SQLite, MongoDB and Redis, Microsoft SQL Server on Linux subsystems.
