Set up an Azure SQL Server virtual machine as an IPython Notebook server for advanced analytics
This topic shows how to provision and configure an SQL Server virtual machine to be used as part of a cloud-based data science environment. The Windows virtual machine is configured with supporting tools such as IPython Notebook, Azure Storage Explorer, and AzCopy, as well as other utilities that are useful for data science projects. Azure Storage Explorer and AzCopy, for example, provide convenient ways to upload data to Azure blob storage from your local machine or to download it to your local machine from blob storage.
The Azure virtual machine gallery includes several images that contain Microsoft SQL Server. Select an SQL Server VM image that is suitable for your data needs. Recommended images are:
- SQL Server 2012 SP2 Enterprise for small to medium data sizes
SQL Server 2012 SP2 Enterprise Optimized for DataWarehousing Workloads for large to very large data sizes
SQL Server 2012 SP2 Enterprise image does not include a data disk. You will need to add and/or attach one or more virtual hard disks to store your data. When you create an Azure virtual machine, it has a disk for the operating system mapped to the C drive and a temporary disk mapped to the D drive. Do not use the D drive to store data. As the name implies, it provides temporary storage only. It offers no redundancy or backup because it doesn't reside in Azure storage.
Connect to the Azure Classic Portal and provision an SQL Server virtual machine
- Log in to the Azure Classic portal using your account. If you do not have an Azure account, visit Azure free trial.
- On the Azure Classic portal, at the bottom left of the web page, click +NEW, click COMPUTE, click VIRTUAL MACHINE, and then click FROM GALLERY.
On the Create a Virtual Machine page, select a virtual machine image containing SQL Server based on your data needs, and then click the next arrow at the bottom right of the page. For the most up-to-date information on the supported SQL Server images on Azure, see Getting Started with SQL Server in Azure Virtual Machines topic in the SQL Server in Azure Virtual Machines documentation set.
On the first Virtual Machine Configuration page, provide the following information:
- Provide a VIRTUAL MACHINE NAME.
- In the NEW USER NAME box, type unique user name for the VM local administrator account.
- In the NEW PASSWORD box, type a strong password. For more information, see Strong Passwords.
- In the CONFIRM PASSWORD box, retype the password.
Select the appropriate SIZE from the drop down list.
The size of the virtual machine is specified during provisioning: A2 is the smallest size recommended for production workloads. The minimum recommended size for a virtual machine is A3 when using SQL Server Enterprise Edition. Select A3 or higher when using SQL Server Enterprise Edition. Select A4 when using SQL Server 2012 or 2014 Enterprise Optimized for Transactional Workloads images. Select A7 when using SQL Server 2012 or 2014 Enterprise Optimized for Data Warehousing Workloads images. The size selected limits the number of data disks you can configure. For most up-to-date information on available virtual machine sizes and the number of data disks that you can attach to a virtual machine, see Virtual Machine Sizes for Azure. For pricing information, see VIrtual Macines Pricing.
Click the next arrow on the bottom right to continue.
On the second Virtual machine configuration page, configure resources for networking, storage, and availability:
- In the Cloud Service box, choose Create a new cloud service.
- In the Cloud Service DNS Name box, provide the first portion of a DNS name of your choice, so that it completes a name in the format TESTNAME.cloudapp.net
- In the REGION/AFFINITY GROUP/VIRTUAL NETWORK box, select a region where this virtual image will be hosted.
- In the Storage Account, select an existing storage account or select an automatically generated one.
- In the AVAILABILITY SET box, select (none).
- Read and accept the pricing information.
- In the ENDPOINTS section, click in the empty dropdown under NAME, and select MSSQL then type the port number of the instance of the Database Engine (1433 for the default instance).
Your SQL Server VM can also serve as an IPython Notebook Server, which will be configured in a later step. Add a new endpoint to specify the port to use for your IPython Notebook server. Enter a name in the NAME column, select a port number of your choice for the public port, and 9999 for the private port.
Click the next arrow on the bottom right to continue.
Accept the default Install VM agent option checked and click the the check mark in the bottom right corner of the wizard to complete the VM provisioning process.
Wait while Azure prepares your virtual machine. Expect the virtual machine status to proceed through:
- Starting (Provisioning)
- Starting (Provisioning)
- Running (Provisioning)
Open the virtual machine using Remote Desktop and complete setup
- When provisioning completes, click on the name of your virtual machine to go to the DASHBOARD page. At the bottom of the page, click Connect.
- Choose to open the rpd file using the Windows Remote Desktop program
- At the Windows Security dialog box, provide the password for the local administrator account that you specified in an earlier step. (You might be asked to verify the credentials of the virtual machine.)
- The first time you log on to this virtual machine, several processes
may need to complete, including setup of your desktop, Windows
updates, and completion of the Windows initial configuration tasks
(sysprep). After Windows sysprep completes, SQL Server setup
completes configuration tasks. These tasks may cause a delay of a
few minutes while they complete.
SELECT @@SERVERNAMEmay not return the correct name until SQL Server setup completes, and SQL Server Management Studio may not be visable on the start page.
Once you are connected to the virtual machine with Windows Remote Desktop, the virtual machine works much like any other computer. Connect to the default instance of SQL Server with SQL Server Management Studio (running on the virtual machine) in the normal way.
Install IPython Notebook and other supporting tools
To configure your new SQL Server VM to serve as an IPython Notebook server, and install additional supporting tools such AzCopy, Azure Storage Explorer, useful Data Science Python packages, and others, a special customization script is provided to you. To install:
- Right-click the Windows Start icon and click Command Prompt (Admin)
Copy the following commands and paste at the command prompt.
set script='https://raw.githubusercontent.com/Azure/Azure-MachineLearning-DataScience/master/Misc/MachineSetup/Azure_VM_Setup_Windows.ps1' @powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString(%script%))"
- When prompted, enter a password of your choice for the IPython Notebook server.
- The customization script automates several post-install procedures, which include:
- Installation and setup of IPython Notebook server
- Opening TCP ports in the Windows firewall for the endpoints created earlier:
- For SQL Server remote connectivity
- For IPython Notebook server remote connectivity
- Fetching sample IPython notebooks and SQL scripts
- Downloading and installing useful Data Science Python packages
- Downloading and installing Azure tools such as AzCopy and Azure Storage Explorer
- You may access and run IPython Notebook from any local or remote browser using a URL of the form
https://<virtual_machine_DNS_name>:<port>, where port is the IPython public port you selected while provisioning the virtual machine.
- IPython Notebook server is running as a background service and will be restarted automatically when you restart the virtual machine.
Attach data disk as needed
If your VM image does not include data disks, i.e., disks other than C drive (OS disk) and D drive (temporary disk), you need to add one or more data disks to store your data. The VM image for SQL Server 2012 SP2 Enterprise Optimized for DataWarehousing Workloads comes pre-configured with additional disks for SQL Server data and log files.
Do not use the D drive to store data. As the name implies, it provides temporary storage only. It offers no redundancy or backup because it doesn't reside in Azure storage.
To attach additional data disks, follow the steps described in How to Attach a Data Disk to a Windows Virtual Machine, which will guide you through:
- Attaching empty disk(s) to the virtual machine provisioned in earlier steps
- Initialization of the new disk(s) in the virtual machine
Connect to SQL Server Management Studio and enable mixed mode authentication
The SQL Server Database Engine cannot use Windows Authentication without domain environment. To connect to the Database Engine from another computer, configure SQL Server for mixed mode authentication. Mixed mode authentication allows both SQL Server Authentication and Windows Authentication. SQL authentication mode is required in order to ingest data directly from your SQL Server VM databases in the Azure Machine Learning Studio using the Import Data module.
While connected to the virtual machine by using Remote Desktop, use the Windows Search pane and type SQL Server Management Studio (SMSS). Click to start the SQL Server Management Studio (SSMS). You may want to add a shortcut to SSMS on your Desktop for future use.
The first time you open Management Studio it must create the users Management Studio environment. This may take a few moments.
When opening, Management Studio presents the Connect to Server dialog box. In the Server name box, type the name of the virtual machine to connect to the Database Engine with the Object Explorer. (Instead of the virtual machine name you can also use (local) or a single period as the Server name. Select Windows Authentication, and leave your_VM_name\your_local_administrator in the User name box. Click Connect.
You may change the SQL Server authentication mode using a Windows registry key change or using the SQL Server Management Studio. To change authentication mode using the registry key change, start a New Query and execute the following script:
USE master go EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'LoginMode', REG_DWORD, 2 go
To change the authentication mode using SQL Server management Studio:
In SQL Server Management Studio Object Explorer, right-click the name of the instance of SQL Server (the virtual machine name), and then click Properties.
On the Security page, under Server authentication, select SQL Server and Windows Authentication mode, and then click OK.
- In the SQL Server Management Studio dialog box, click OK to acknowledge the requirement to restart SQL Server.
In Object Explorer, right-click your server, and then click Restart. (If SQL Server Agent is running, it must also be restarted.)
- In the SQL Server Management Studio dialog box, click Yes to agree that you want to restart SQL Server.
Create SQL Server authentication logins
To connect to the Database Engine from another computer, you must create at least one SQL Server authentication login.
You may create new SQL Server logins programmatically or using the SQL Server Management Studio. To create a new sysadmin user with SQL authentication programmatically, start a New Query and execute the following script. Replace <new user name> and <new password> with your choice of user name and password.
USE master go CREATE LOGIN <new user name> WITH PASSWORD = N'<new password>', CHECK_POLICY = OFF, CHECK_EXPIRATION = OFF; EXEC sp_addsrvrolemember @loginame = N'<new user name>', @rolename = N'sysadmin';
Adjust the password policy as needed (the sample code turns off policy checking and password expiration). For more information about SQL Server logins, see Create a Login.
To create new SQL Server logins using the SQL Server Management Studio:
- In SQL Server Management Studio Object Explorer, expand the folder of the server instance in which you want to create the new login.
Right-click the Security folder, point to New, and select Login….
- In the Login - New dialog box, on the General page, enter the name of the new user in the Login name box.
- Select SQL Server authentication.
- In the Password box, enter a password for the new user. Enter that password again into the Confirm Password box.
- To enforce password policy options for complexity and enforcement, select Enforce password policy (recommended). This is a default option when SQL Server authentication is selected.
- To enforce password policy options for expiration, select Enforce password expiration (recommended). Enforce password policy must be selected to enable this checkbox. This is a default option when SQL Server authentication is selected.
- To force the user to create a new password after the first time the login is used, select User must change password at next login (Recommended if this login is for someone else to use. If the login is for your own use, do not select this option.) Enforce password expiration must be selected to enable this checkbox. This is a default option when SQL Server authentication is selected.
- From the Default database list, select a default database for the login. master is the default for this option. If you have not yet created a user database, leave this set to master.
In the Default language list, leave default as the value.
If this is the first login you are creating, you may want to designate this login as a SQL Server administrator. If so, on the Server Roles page, check sysadmin.
Members of the sysadmin fixed server role have complete control of the Database Engine. For security reasons, you should carefully restrict membership in this role.
- Click OK.
Determine the DNS name of the virtual machine
To connect to the SQL Server Database Engine from another computer, you must know the Domain Name System (DNS) name of the virtual machine.
(This is the name the internet uses to identify the virtual machine. You can use the IP address, but the IP address might change when Azure moves resources for redundancy or maintenance. The DNS name will be stable because it can be redirected to a new IP address.)
- In the Azure Classic Portal (or from the previous step), select VIRTUAL MACHINES.
- On the VIRTUAL MACHINE INSTANCES page, in the DNS NAME column, find and copy the DNS name for the virtual machine which appears preceded by http://. (The user interface might not display the entire name, but you can right-click on it, and select copy.)
Connect to the Database Engine from another computer
- On a computer connected to the internet, open SQL Server Management Studio.
- In the Connect to Server or Connect to Database Engine dialog box, in the Server name box, enter the DNS name of the virtual machine (determined in the previous task) and a public endpoint port number in the format of DNSName,portnumber such as tutorialtestVM.cloudapp.net,57500.
- In the Authentication box, select SQL Server Authentication.
- In the Login box, type the name of a login that you created in an earlier task.
- In the Password box, type the password of the login that you create in an earlier task.
- Click Connect.
Connect to the Database Engine from Azure Machine Learning
In later stages of the Team Data Science Process, you will use the Azure Machine Learning Studio to build and deploy machine learning models. To ingest data from your SQL Server VM databases directly into Azure Machine Learning for training or scoring, use the Import Data module in a new Azure Machine Learning Studio experiment. This topic is covered in more details through the Team Data Science Process guide links. For an introduction, see What is Azure Machine Learning Studio?.
- In the Properties pane of the Import Data module, select Azure SQL Database from the Data Source dropdown list.
- In the Database server name text box, enter
tcp:<DNS name of your virtual machine>,1433
- Enter the SQL user name in the Server user account name text box.
Enter the sql user's password in the Server user account password text box.
Shutdown and deallocate virtual machine when not in use
Azure Virtual Machines are priced as pay only for what you use. To ensure that you are not being billed when not using your virtual machine, it has to be in the Stopped (Deallocated) state.
Shutting down the virtual machine from inside (using Windows power options), the VM is stopped but remains allocated. To ensure you’re not being billed, always stop virtual machines from the Azure Classic Portal. You can also stop the VM through Powershell by calling ShutdownRoleOperation with "PostShutdownAction" equal to "StoppedDeallocated".
To shutdown and deallocate the virtual machine:
- Log in to the Azure Classic Portal using your account.
- Select VIRTUAL MACHINES from the left navigation bar.
- In the list of virtual machines, click on the name of your virtual machine then go to the DASHBOARD page.
- At the bottom of the page, click SHUTDOWN.
The virtual machine will be deallocated but not deleted. You may restart your virtual machine at any time from the Azure Classic Portal.
Your Azure SQL Server VM is ready to use: what's next?
Your virtual machine is now ready to use in your data science exercises. The virtual machine is also ready for use as an IPython Notebook server for the exploration and processing of data, and other tasks in conjunction with Azure Machine Learning and the Team Data Science Process (TDSP).
The next steps in the data science process are mapped in the Team Data Science Process and may include steps that move data into HDInsight, process and sample it there in preparation for learning from the data with Azure Machine Learning.
