• IT Landscape is Constantly Changing• Many OSs (Linux, Windows, etc.), different languages, multiple data types• Mix of on-premises/cloud/hybrid environments• Complex environments can challenge IT to:

• Require specific skill sets (personnel)• Reduce operational costs

• Microsoft has committed to providing interoperability to open source• Gives industry leading performance & security• TPC benchmark stats for SQL Server 2017 on Linux

• http://www.tpc.org/tpch/results/tpch_result_detail.asp?id=117041701

• Security supports Active Directory authentication • Single sign-on with no password• Uses domain credentials and Kerberos protocol

• Three Main Editions – Express, Standard & Enterprise• Rewritten so there is common programming across all editions

• Develop once and purchase different editions to scale

• Developer & Test edition include Enterprise features

• Buy same SKUs and get rights to run on both Windows & Linux• SQL Server Software Assurance Benefits (SA)

• Standard / Enterprise • Next version rights • License Mobility to shared 3rd party servers• Fail-Over servers for high availability

• Enterprise • Machine Learning Server for Hadoop

• https://blogs.technet.microsoft.com/dataplatforminsider/2017/09/26/in-database-machine-learning-in-sql-server-2017/

• Power BI Report Server

• Need to acquire when buying initial license – can’t add later

SQL Server 2017 Licensing


https://blogs.technet.microsoft.com/dataplatforminsider/2017/09/26/in-database-machine-learning-in-sql-server-2017/

• License Mobility• Requires SA on licenses running the workload• Deploy your workload only to authorized Mobility Partners

• Fail-Over servers for high availability• Combined with license mobility, provides full flexibility on dedicated or 3rd party

• For planned or unplanned downtime

• Secondary/passive SQL server is granted through SA• Without SA, both active & passive servers need to be licensed• 90 day reassignment rule is waived due to License Mobility SA benefits

• Limited Time Special Offer Runs October 2nd – June 30th, 2018• Red Hat & Microsoft have created a promotion

• New orders for RHEL Enterprise Linux for use on SQL Server 2017• Webinar - SQL Server 2017 Pricing & Licensing Microsoft Engineering Town Hall

• / = Root• Every single file & directory starts here• Only ‘root’ user has write privilege • /root is ‘root’ user’s home directory

• Not the same as /

• /var = Variable Files• Files can grow under this directory • SQL Server default directory

• /var/opt/mssql• Holds log and config files

• Also system log files, database files, etc

• /opt = Optional add-on Applications• Holds SQL Server application (default)

• /opt/mssql/bin• /opt/msql/lib

Linux Directory Structure

• Directory != Drive• /var/opt/mssql/data can be on different device than /var/opt/mssql/log

• A ‘mssql’ user & ‘mssql’ group is automatically setup on install• Home directory is /home/mssql • Application files are owned by ‘mssql’

• Some commands need ‘sudo’ privileges• ‘sudo’ means ‘Super User Do’

• Linux is case sensitive• ‘hello world’ != ‘HELLO WORLD’

• Hidden files are prefaced with a dot• .bash_profile

• Bash Shell is common command language• Built from Bourne shell with added plugins (Bourne Again Shell)• Used for scripting

More About Linux


• ls -ltra• List directory contents (i.e. ls –ltra /var/opt/mssql)• -l = long listing –t = sort newest first –r = reverse –a all files

• cd • Change directory (i.e. cd /var/opt/mssql/log)

• ps –ef• Displays active processes (i.e. ps –ef | grep sql)• -e = every process –f = full format listing• top = interactive view

• grep• Seaches files or standard output for pattern matching

• Example: history | grep –i mssql-conf

• man• Interface to on-line reference manuals (i.e. man ps)

Useful Linux Commands

A great way to get familiar with

Linux commands is to download:

http://www.cygwin.com/

Provides functionality similar to a

Linux distribution on Windows.

Installing SQL Server 2017 Container Image with Docker

wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.09.0.ce-1.el7.centos.x86_64.rpm

sudo yum install ./docker-ce-17.09.0.ce-1.el7.centos.x86_64.rpm

systemctl start docker

sudo docker run hello-world

Docker provides an additional layer of

abstraction & automation at the operating-

system-level. It can package an application &

its dependencies in a virtual container. This

helps enable flexibility & portability to run on-

premises, public & private cloud, bare metal,

etc.

https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.09.0.ce-1.el7.centos.x86_64.rpm

• Get SQL Server for Linux

• Create container called sql1
