目录：

• Prerequisites
• 集群配置规划
• polybase install
• firewall config
• 集群配置
• 删除计算节点

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下载地址： 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

集群配置规划：

---

• 3台Azure A3 虚拟机（polybase0、polybase1、polybase2)，虚拟机在同一虚拟子网

1. 1. polybase0：域控服务器
   2. polybase1、polybase2 同一域内二台测试机

• 域帐户： jn\zhushy
• 说明： 在polybase1、polybase2安装sqlserver2016 with polybase

polybase install

---

• 启动安装向导，在如下的界面选择"New Standalone SQL Server installation or add features",如图：
• 
• 在执行“ feature selection page” 时，选择“PolyBase Query Service for External Data”
• 
• PolyBase Configuration Page 项，配置如下：
• 
• Server Configuration Page 项，configure the SQL Server PolyBase Engine Service and SQL Server PolyBase Data Movement Service to run under the same account
• 
• 安装完成后，如下
• 
• 
• 在上面链接下载的sqlserver2016未集成ssms，需单独安装，通过下面的sql判断是否安装正常

  SELECT SERVERPROPERTY ('IsPolybaseInstalled') AS IsPolybaseInstalled

• 返回“1”则表示安装成功，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. 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

• 如下图：
• 

集群配置

---

• 选择polybase1作为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

• 连接到sqlserver on polybase1, 查看集群节点状况，如下： select * from sys.dm_exec_compute_nodes
• 

删除计算节点：

---

• 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
