DW(五):polybase集群安裝

 目錄：

• Prerequisites
• 集群配置規劃
• 創建域控伺服器
• polybase install
• firewall config
• 集群配置
• 刪除計算節點

install Prerequisites

• Microsoft .NET Framework 4.5
• Oracle Java SE RunTime Environment (JRE) version 7.51 or higher (64-bit) (Either JRE or Server JRE will work)
• Minimum memory: 4GB
• Minimum hard disk space: 2GB
• TCP/IP connectivity must be enabled
• SQL Server (starting with 2016)
• JRE下載地址： http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
• sqlserver2016: https://www.microsoft.com/en-us/evalcenter/evaluate-sql-server-2016?i=1
• ssms2016(SQL Server Management Studio): https://msdn.microsoft.com/en-us/library/mt238290.aspx

集群配置規劃：

• 3台Azure A3 虛擬機（polybase0、polybase1、polybase2)，虛擬機在同一虛擬子網

1. 1. polybase0：域控伺服器
   2. polybase1、polybase2 同一域內二台測試機

• 域帳戶： jn\zhushy
• 說明： 在polybase1、polybase2安裝sqlserver2016 with polybase

polybase install

• 啟動安裝嚮導，在如下的界面選擇"New Standalone SQL Server installation or add features",如圖：
• 
• 在執行“ feature selection page” 時，選擇“PolyBase Query Service for External Data”
• 
• PolyBase Configuration Page 項，配置如下：
• 
• Server Configuration Page 項，configure the SQL Server PolyBase Engine Service and SQL Server PolyBase Data Movement Service to run under the same account
• 
• 安裝完成後，如下
• 
• 
• 在上面鏈接下載的sqlserver2016未集成ssms，需單獨安裝，通過下麵的sql判斷是否安裝正常

  SELECT SERVERPROPERTY ('IsPolybaseInstalled') AS IsPolybaseInstalled

•  返回“1”則表示安裝成功，如下

• 

firewall config

• SQL Server PolyBase setup creates the following firewall rules on the machine

1. 1. SQL Server PolyBase – Database Engine - <SQLServerInstanceName> (TCP-In)
   2. SQL Server PolyBase – PolyBase Services - <SQLServerInstanceName> (TCP-In)
   3. SQL Server PolyBase - SQL Browser - (UDP-In)

• To enable the firewall rules

1. 1. Open the Control Panel
   2. Click System and Security, and click Windows Firewall
   3. click Advanced Settings, and click Inbound rules
   4. Right-click the disabled rule, then click Enable rule

• 如下圖：
• 

集群配置

• 選擇polybase1作為headnode
• Connect to SQL Server on polybase2. Run the stored procedure sp_polybase_join_group.

  -- Enter head node details:   
  -- head node machine name, head node dms control channel port, head node sql server name  
  EXEC sp_polybase_join_group 'polybase1', 16450, 'MSSQLSERVER'; 

•  Shutdown the PolyBase engine and restart the PolyBase data movement service

• 連接到sqlserver on polybase1, 查看集群節點狀況，如下： select * from sys.dm_exec_compute_nodes
• 

刪除計算節點：

• Connect to the compute node SQL Server (polybase2).
• Run the stored procedure sp_polybase_leave_group.

  EXEC sp_polybase_leave_group;

• on polybase2 : Start PolyBase Engine. Restart PolyBase data movement service.
• Now polybase2 will function as a standalone head node
