DW(五):polybase集群安装
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
[*]
[*]polybase0：域控服务器
[*]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
[*]
[*]SQL Server PolyBase – Database Engine - <SQLServerInstanceName> (TCP-In)
[*]SQL Server PolyBase – PolyBase Services - <SQLServerInstanceName> (TCP-In)
[*]SQL Server PolyBase - SQL Browser - (UDP-In)
[*]To enable the firewall rules
[*] Open the Control Panel
[*]Click System and Security, and click Windows Firewall
[*]click Advanced Settings, and click Inbound rules
[*]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
