In December 2016 Microsoft made their SQL Server database available in Linux. Here we’ll cover how to install and perform basic setup of MSSQL in the Ubuntu distribution of Linux.
First we’ll set up the repository file, Microsoft provide a copy of this for Ubuntu here: https://packages.microsoft.com/config/ubuntu/16.04/mssql-server.list
We’ll use the wget command to copy this file to the /etc/apt/sources.list.d directory so that we can use it using apt-get. After this we run ‘apt-get update’ in order to sync the package index files with the new source that we’ve just added.
root@ubuntu:~# wget https://packages.microsoft.com/config/ubuntu/16.04/mssql-server.list -O /etc/apt/sources.list.d/mssql-server.list root@ubuntu:~# apt-get update
At the time of writing, the 16.10 directory at https://packages.microsoft.com/ubuntu/16.10/mssql-server/ was empty, so I have instead used the 16.04 files here which seems to have worked just fine.
Now that the repository file is in place, installation is as simple as running the following command. At the time of writing the total size of the package and all dependencies was a 747mb download.
root@ubuntu:~# apt-get install mssql-server -y ... +-------------------------------------------------------------------+ | Please run /opt/mssql/bin/sqlservr-setup to complete the setup of | | Microsoft(R) SQL Server(R). | +-------------------------------------------------------------------+
Once the installation has completed, we are advised to run the /opt/mssql/bin/sqlservr-setup bash script to complete the setup process.
During my first installation attempt, I got the following error as my virtual machine was only running with 2GB of memory, so be sure that you have enough memory before proceeding.
sqlservr: This program requires a machine with at least 3250 megabytes of memory. Microsoft(R) SQL Server(R) setup failed with error code 1.
You’ll be able to proceed once you have adequate memory available.
root@ubuntu:~# /opt/mssql/bin/sqlservr-setup Microsoft(R) SQL Server(R) Setup You can abort setup at anytime by pressing Ctrl-C. Start this program with the --help option for information about running it in unattended mode.

If so, please type "YES": YES Please enter a password for the system administrator (SA) account: Please confirm the password for the system administrator (SA) account: Setting system administrator (SA) account password...

Created symlink /etc/systemd/system/multi-user.target.wants/mssql-server-telemetry.service â /lib/systemd/system/mssql-server-telemetry.service. Setup completed successfully.
That’s it, Microsoft SQL Server is now running successfully and listening for traffic on TCP port 1434.
root@ubuntu:~# systemctl status mssql-server â mssql-server.service - Microsoft(R) SQL Server(R) Database Engine Loaded: loaded (/lib/systemd/system/mssql-server.service; enabled; vendor preset: enabled) Active: active (running) since Fri 2016-12-30 22:55:23 AEDT; 33s ago Main PID: 4164 (sqlservr) CGroup: /system.slice/mssql-server.service ââ4164 /opt/mssql/bin/sqlservr ââ4201 /opt/mssql/bin/sqlservr root@ubuntu:~# netstat -antp | grep 1434 tcp 0 0 127.0.0.1:1434 0.0.0.0:* LISTEN 4201/sqlservr
In order to actually connect to the server from Linux we need to install the mssql-tools package, which comes from a different repository than the one that we just set up. It can be found here: https://packages.microsoft.com/config/ubuntu/16.04/prod.list
First we’ll download a copy of the prod.list file and place it into the /etc/apt/sources.list.d directory.
root@ubuntu:~# wget https://packages.microsoft.com/config/ubuntu/16.04/prod.list -O /etc/apt/sources.list.d/pord.list root@ubuntu:~# apt-get update
We can now proceed with installing the mssql-tools package, as shown below.
root@ubuntu:~# apt-get install mssql-tools -y
Once this is installed we can use the sqlcmd command to interact with the database. To see how to run sqlcmd, simply run it with the -? option for help.
Unfortunately it appears that when you specify the -P option for the password, the password must be provided in the command line with no option of being prompted for it later. Keep in mind that your password will be stored in your bash history running it this way.
root@ubuntu:~# sqlcmd -U SA -P password 1> create database test; 2> go 1> use test; 2> go Changed database context to 'test'. 1> create table websites(domain varchar(255)); 2> go 1> insert into websites (domain) 2> values ('rootusers.com'); 3> go (1 rows affected) 1> select domain 2> from websites; 3> go domain rootusers.com (1 rows affected)
In this example we create a test database with a table named websites and a column for domain names. We then insert a domain name and pull it back out with select, confirming both that we are able to connect and that basic SQL queries appear to be working as expected.
Microsoft’s SQL Server is now available for installation on Linux. Personally I don’t think I’ll ever use this over other alternatives such as MariaDB or PostgreSQL, so hopefully someone somewhere actually finds this information useful!
The answer (and an increasingly common answer, I might add) is Docker. Here are the steps that worked for me.
If you don’t already have Docker installed, you’ll need to download and install it.
Next step, you’ll need to increase Docker’s available memory to 4GB or more.
Open a Terminal window, and download the latest SQL Server for Linux Docker image.
docker pull microsoft/mssql-server-linux
Now, launch an instance of the Docker image.
docker run -d --name name_your_container -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=P@55w0rd' -p 1433:1433 microsoft/mssql-server-linux
You should now have SQL Server running on your Mac, ready for action!
-d: this launches the container in daemon mode, so it runs in the background
--name name_your_container: give your Docker container a friendly name, which is useful for stopping and starting containers from the Terminal.
-e 'ACCEPT_EULA=Y: this sets an environment variable in the container named
ACCEPT_EULAto the value
Y. This is required to run SQL Server for Linux.
-e 'SA_PASSWORD=P@55w0rd': this sets an environment variable for the
sadatabase password. Set this to your own strong password. Also required.
-p 1433:1433: this maps the local port 1433 to the container’s port 1433. SQL Server, by default, listens for connections on TCP port 1433.
microsoft/mssql-server-linux: this final parameter tells Docker which image to use
Kitematic is a nice desktop application for managing Docker containers. The first time you click Open Kitematic, it will prompt you to download and install it. You can then use Kitematic to view the output of your containers, manage their settings, etc.
From the Terminal, install
sql-cli globally, so you can use it anywhere.
npm install -g sql-cli
Next, connect to your SQL Server instance running in Docker.
mssql -u sa -p P@55w0rd
You can now query and execute SQL Server commands from the
.quit and press Enter to exit.
I haven’t tried restoring a database from backup, yet. Instead, I chose to script out an existing database and use
sql-cli to run the scripts to recreate my database running in Docker.
First step is to use SQL Server Management Studio to generate scripts from an existing database.
Right-click on your database, and choose Tasks -> Generate Scripts…
I chose to separate my table and data scripts from my Views, Stored Procedures, User-Defined Functions, etc.
Next, click on Advanced
I chose to “Check for object existence,” “Script DROP and CREATE,” and set “Types of data to script” to “Schema and data.”
Checking for object existence and DROP/CREATE allows me to re-run the same script against an existing database, if I want to reset it back to its original state.
Choose a location to save your scripts. When finished, repeat the steps to script out your Views, Stored Procedures, and UDFs, if necessary.
sql-cli, and make sure you are on
mssql> use master
mssql> CREATE DATABASE devdb
devdbto match the name of the database you scripted. The generated scripts expect a database with that same name to exist.
devdbto match your database name)
mssql> use devdb
mssql> .run script.sql
You now have a copy of your database, running on your Mac, without the need for entire Windows VM!
