Install on Linux - SQL Server 2019 Machine Learning Services

Applies to: SQL Server 2019 (15.x) - Linux

This article guides you in the installation of SQL Server Machine Learning Services on Linux. Python and R scripts can be executed in-database using Machine Learning Services.

You can install Machine Learning Services on Red Hat Enterprise Linux (RHEL), SUSE Linux Enterprise Server (SLES), and Ubuntu. For more information, see the Supported platforms section in the Installation guidance for SQL Server on Linux.

• Installation guidance for SQL Server on Linux and verify the installation.

• Check the SQL Server Linux repositories for the Python and R extensions. If you already configured source repositories for the database engine install, you can run the mssql-mlservices package install commands using the same repo registration.

• (R only) Microsoft R Open (MRO) provides the base R distribution for the R feature in SQL Server and is a prerequisite for using RevoScaleR, MicrosoftML, and other R packages installed with Machine Learning Services.

  • The required version is MRO 3.5.2.
  • Register the packages.microsoft.com repo as described later in this article to install the MRO distribution: microsoft-r-open-mro and microsoft-r-open-mkl.
  • See the installation sections later in this article for how to install MRO.

• You should have a tool for running T-SQL commands.

  • You can connect to an instance of SQL Server using any familiar SQL Server client tool, such as sqlcmd, SQL Server Management Studio (SSMS), or the MSSQL extension for Visual Studio Code.

On an internet-connected device, packages are downloaded and installed independently of the database engine using the package installer for each operating system. The following table describes all available packages, but for R and Python, you specify packages that provide either the full feature installation or the minimum feature installation.

Available installation packages:

Excludes pretrained models.

Excludes pretrained models.

Follow these steps to install SQL Server Machine Learning Services on Red Hat Enterprise Linux (RHEL).

The following commands register the repository providing MRO. Post-registration, the commands for installing other R packages, such as mssql-mlservices-mml-r, automatically include MRO as a package dependency.

# Import the Microsoft repository key

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc

# Set the location of the package repo at the "prod" directory
# The following command is for version 8.x
# To get the version for 6.x or 7.x, replace 8 with 6 or 7, respectively.
rpm -Uvh https://packages.microsoft.com/config/rhel/8/packages-microsoft-prod.rpm

# Update packages on your system (optional)
yum update

Installation Options for Python and R:

• Install language support based on your requirements (single or multiple languages).
• The full installation provides all available features including pretrained machine learning models.

Additional configuration is primarily through the mssql-conf tool.

1. After the package installation finishes, run mssql-conf setup and follow the prompts to set the sa password and choose your edition. Perform this step only if SQL Server on Linux isn't configured yet.

   sudo /opt/mssql/bin/mssql-conf setup
   

2. Accept the licensing agreements for open-source Python and R extensions. Use the following command:

   # Run as SUDO or root
   # Use set + EULA
   sudo /opt/mssql/bin/mssql-conf set EULA accepteulaml Y
   

   Setup detects the mssql-mlservices packages and prompts for EULA acceptance (if not previously accepted) when mssql-conf setup is run. For more information about EULA parameters, see Configure SQL Server with the mssql-conf tool.

3. Enable outbound network access. Outbound network access is disabled by default. To enable outbound requests, set the "outboundnetworkaccess" Boolean property using the mssql-conf tool. For more information, see Configure SQL Server on Linux with mssql-conf.

   # Run as SUDO or root
   # Enable outbound requests over the network
   sudo /opt/mssql/bin/mssql-conf set extensibility outboundnetworkaccess 1
   

4. For R feature integration only, set the MKL_CBWR environment variable to ensure consistent output from Intel Math Kernel Library (MKL) calculations.

   • Edit or create a file .bash_profile in your user home directory, adding the line export MKL_CBWR="AUTO" to the file.

   • Execute this file by typing source .bash_profile at a bash command prompt.

5. Restart the SQL Server Launchpad service and the database engine instance to read the updated values from the INI file. A notification message is displayed when an extensibility-related setting is modified.

   systemctl restart mssql-launchpadd
   
   systemctl restart mssql-server.service
   

6. Enable external script execution. You can connect to an instance of SQL Server using any familiar SQL Server client tool, such as sqlcmd, SQL Server Management Studio (SSMS), or the MSSQL extension for Visual Studio Code.

   EXECUTE sp_configure 'external scripts enabled', 1;
   
   RECONFIGURE WITH OVERRIDE;
   

7. Restart the Launchpad service again.

R libraries (MicrosoftML, RevoScaleR, and others) can be found at /opt/mssql/mlservices/libraries/RServer.

Python libraries (microsoftml and revoscalepy) can be found at /opt/mssql/mlservices/libraries/PythonServer.

To validate installation:

• Run a T-SQL script that executes a system stored procedure invoking Python or R using a query tool.

• Execute the following T-SQL command to test R execution in SQL Server. Errors? Try a service restart, sudo systemctl restart mssql-server.service.

  EXECUTE sp_execute_external_script
      @language = N'R',
      @script = N'
          OutputDataSet <- InputDataSet', @input_data_1 = N'SELECT 1 AS hello'
      WITH RESULT SETS
  (
          ([hello] INT NOT NULL)
  );
  GO
  

• Execute the following T-SQL command to test Python execution in SQL Server.

  EXECUTE sp_execute_external_script
      @language = N'Python',
      @script = N'
          OutputDataSet = InputDataSet;', @input_data_1 = N'SELECT 1 AS hello'
      WITH RESULT SETS
  (
          ([hello] INT NOT NULL)
  );
  GO
  

Using the unattended install for the Database Engine, add the packages for mssql-mlservices and EULAs.

Use one of the mlservices-specific EULA parameters for the open-source R and Python distributions:

sudo /opt/mssql/bin/mssql-conf setup accept-eula-ml

The complete EULA is documented at Configure SQL Server on Linux with the mssql-conf tool.

Follow the Offline installation instructions for steps on installing the packages. Find your download site, and then download specific packages using the package list that follows.

Tip

Several of the package management tools provide commands that can help you determine package dependencies. For yum, use sudo yum deplist [package]. For Ubuntu, use sudo apt-get install --reinstall --download-only [package name] followed by dpkg -I [package name].deb.

Download packages from https://packages.microsoft.com/. All of the mlservices packages for Python and R are colocated with database engine package. Base version for the mlservices packages is 9.4.6. Recall that the microsoft-r-open packages are in a different repository.

Select extensions you want to use and download the packages necessary for a specific language. The filenames include platform information in the suffix.

Depending on which extensions you want to use, download the packages necessary for a specific language. Exact filenames include platform information in the suffix, but the following file names should be close enough for you to determine which files to get.
