6 WHAT THIS PRESENTATION COVERS SQL Server on Linux background Editions Feature set Architecture Installation Connecting from SSMS Migrating databases Using the cross-platform toolset

7 Getting started with SQL Server on Linux

8 SQL SERVER ON LINUX EDITIONS Enterprise Standard Web Express Developer Evaluation

9 SQL SERVER ON LINUX SCALABILITY Maximum Enterprise Standard Web Express Maximum compute capacity Maximum memory for buffer pool Maximum relational database size OS maximum Lesser of 4 sockets or 24 cores OS maximum (24 TB) Lesser of 4 sockets or 16 cores Lesser of 1 socket or 4 cores 128 GB 64 GB 1410 MB 524 PB 524 PB 524 PB 10 GB

10 Features Features SQL Server in Windows SQL Server on Linux Relational Database Engine Yes Yes Analysis Services, Integration Services, Reporting Services, R Services Yes No In-Memory OLTP Yes Yes Columnstore Yes Yes Partitioning and data compression Yes Yes Polybase Yes No R Integration Yes No AlwaysOn Failover Yes (Windows Clustering) Yes (Pacemaker) AlwaysOn Availability Groups Yes (Windows Clustering) Yes (Pacemaker) Always Encrypted, RLS, Dynamic Data Yes Yes Masking, TDE FileTable Yes No T-SQL, CLR JSON Yes Yes Stretch Databases Yes No Support for SSMS, SSDT, VS Code Yes Yes

11 SO HOW DID MICROSOFT DO IT? Porting was untenable SQL Server has millions of lines of code Drawbridge Microsoft research project SQL PAL Running Windows x86 binaries

12 GETTING STARTED WITH LINUX The BASH Shell (Bourne-Again Shell) Default for most Linux distributions Terminal

13 HANDY BASH COMMANDS Files and directories Pwd list current dir Ls list files Cd, cd ~, cd.. change dir Rm remove file Mv move file Cp copy file Scp copy file between systems Top - processes Sudo su Systemctl - services Copy & pasting to and from Bash Copy from the shell: highlight text and hit enter Paste into the shell: right-click in the terminal

14 INSTALLING SQL SERVER ON LINUX Supported Linux distributions Red Hat Enterprise Linux 7.2 Ubuntu Linux SUSE Enterprise Server v12 SP2 Online, Offline & unattended

15 INSTALLING SQL SERVER ON UBUNTU curl sudo apt-key add curl sudo tee /etc/apt/sources.list.d/mssql-server.list sudo apt-get update sudo apt-get install -y mssql-server

16 Agent Collation INITIAL CONFIGURATION sudo /opt/mssql/bin/mssql-conf setup Customer feedback Database Mail Profile Default data directory Default log directory Default master database file directory Default master database file name Enable SQL Server Agent Set a new collation for SQL Server on Linux. Choose whether or not SQL Server sends feedback to Microsoft. Set the default database mail profile for SQL Server on Linux Change the default directory for new SQL Server database data files (.mdf). Changes the default directory for new SQL Server database log (.ldf) files. Changes the default directory for the master database files on existing SQL installation. Changes the name of master database files. Default dump directory Default error log directory Default backup directory Dump type High availability Local Audit directory Locale Memory limit TCP port TLS Traceflags Change the default directory for new memory dumps and other troubleshooting files. Changes the default directory for new SQL Server ErrorLog, Default Profiler Trace, System Health Session XE, and Hekaton Session XE files. Change the default directory for new backup files. Choose the type of dump memory dump file to collect. Enable Availability Groups. Set a a directory to add Local Audit files. Set the locale for SQL Server to use. Set the memory limit for SQL Server. Change the port where SQL Server listens for connections. Configure Transport Level Security. Set the traceflags that the service is going to use.

17 systemctl status mssql-server CHECKING THE SERVICE

18 GETTING THE HOST NAME OR IP IP address ifconfig DNS name $ hostname

19 UBUNTU FIREWALL The Ubuntu Uncomplicated Firewall (UFW) Not enabled by default sudo ufw allow 1433

20 CONNECTING DNS name IP address ifconfig Port 1433

21 UPDATING SQL SERVER ON LINUX #check sql server package info apt-cache show mssql-server #Run apt-get update to update the package. apt-get update mssql-server #Update SQL Server sudo apt-get install mssql-server

22 REMOVING SQL SERVER ON LINUX Microsoft s instructions sudo apt-get remove mssql-server sudo rm -rf /var/opt/mssql/ How do I totally remove SQL Server 2017 on Ubuntu? StackOverflow

23 MIGRATING DATABASES Exporting and Importing BACPAC packages BCP SSIS SQL Server Migration Asisstant Backup and restore Same internal database format as Windows /var/opt/mssql/data sqlcmd -S localhost -U SA -Q "RESTORE DATABASE [mydb] FROM DISK = N'/var/opt/mssql/data/mydb.bak' WITH FILE = 1, NOUNLOAD, REPLACE, NORECOVERY, STATS = 5"

24 MIGRATING DATABASES SSMS Database Restore

25 Cross-platform Tools

26 SQLCMD & BCP MSSQL-Tools SQLCMD command line query tool BCP Bulk Copy Program Cross-platform Windows, Linux & Mac No real changes Windows installer from MS downloads Linux installation curl sudo apt-key add curl sudo tee /etc/apt/sources.list.d/msprod.list sudo apt-get update sudo apt-get install mssql-tools unixodbc-dev echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile

27 MSSQL-CLI Modern command line T-SQL execution IntelliSense statement completion, syntax highlighting, a multi-line edit mode and automatic formatting Based on Python Windows installation Python3-6-5.exe pip install mssql-cli Linux installation $ sudo apt-get update & sudo apt-get install -y libunwind8 python-pip libicu52 $ sudo pip install --upgrade pip $ sudo pip install mssql-cli

28 MSSQL-CLI Output formatting

29 MSSQL-CLI SPECIAL COMMANDS Environment variables set MSSQL_CLI_SERVER=localhost set MSSQL_CLI_DATABASE=AdventureWorks2014 set MSSQL_CLI_ROW_LIMIT=20 Internal commands \sn names select LastName, FirstName, Title from Person.Person \n names

30 MSSQL-SCRIPTER Scripts out databases Requires Python Linux sudo apt install python-pip pip install mssql-scripter mssql-scripter -S. -U sa -d AdventureWorks2014 display-progress file-path /temp/

31 SQL OPERATIONS STUDIO (SQLOPS) Based on VS Code Windows, Linux & Mac Full T-SQL development IntelliSense keyword completion code snippets code navigation source control integration

32 SQLOPS SUPPORTED SYSTEMS Windows 10 (64-bit) Windows 8.1 (64-bit) Windows 8 (64-bit) Windows 7 (SP1) (64-bit) - Requires KB Windows Server 2016 Windows Server 2012 R2 (64-bit) Windows Server 2012 (64-bit) Windows Server 2008 R2 (64-bit) macos High Sierra macos Sierra Red Hat Enterprise Linux 7.4 Red Hat Enterprise Linux 7.3 SUSE Linux Enterprise Server v12 SP2 Ubuntu 16.04

33 INSTALLING SQLOPS Windows Download and run installer /fwlink/?linkid= Linux - Ubuntu sudo apt-get install libxss1 sudo apt-get install libgconf-2-4 sudo apt-get install libunwind8 Still in preview Erased my PATH

34 FAQS Can SQL Server run on other Linux distributions? Yes but its not supported by Microsoft Is there a performance hit using SQL Server on Linux No Where are the SQL files at? /var/opt/mssql/data Is there a version of SSMS for Linux No but there is SQLOps

35 ADDITIONAL REFERENCES SQL Server on Linux Jump Start series Installation guidance for SQL Server on Linux Install sqlcmd and bcp the SQL Server command-line tools on Linux Download and install SQL Operations Studio (preview)
