How to install MsSQL Server 2019 on Ubuntu 20.04

Microsoft SQL Server is a relational database management system developed by Microsoft. It is aimed to be used to store and retrieve data by applications. It can be run either on the same computer or on another across a network.

In this guide we are going to install Microsoft Server 2019 in Ubuntu 20.04 or latest server. We then connect with sqlcmd to create your first database and run queries.

Prerequisites

Updated ubuntu 20.04 server
Access to the commandline as root user

Ensure that the server is up to date

Before proceeding, it is always a good practice to make sure that the server we are working on has updated packages. Use this command to ensure that the server is updated

Installing MsSQL Server 2019 in Ubuntu

MsSQL Server is not available in the default Ubuntu repos. To set up the repo and install ubuntu, follow these steps:

Import the public repository GPG keys:

1

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

1

sudo add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/ubuntu/20.04/mssql-server-2019.list)"

Run the following commands to update the new repo and install SQL Server:

2


sudo apt-get update
sudo apt-get install -y mssql-server

Configuring MsSQL Server

After the package installation finishes, run mssql-conf setup and follow the prompts to set the SA password and choose your edition.

1

sudo /opt/mssql/bin/mssql-conf setup

Make sure to specify a strong password for the SA account (Minimum length 8 characters, including uppercase and lowercase letters, base 10 digits and/or non-alphanumeric symbols).

Starting and enabling the service

Once the configuration is done, verify that the service is running:

If you plan to connect remotely, you might also need to open the SQL Server TCP port (default 1433) on your firewall.

At this point, SQL Server 2019 is running on your Ubuntu machine and is ready to use!

If you want to enable the service to start on boot use this command

1

sudo systemctl enable mssql-server

Install the SQL Server command-line tools

To create a database, you need to connect with a tool that can run Transact-SQL statements on the SQL Server. The following steps install the SQL Server command-line tools: sqlcmd and bcp.

Use the following steps to install the mssql-tools on Ubuntu.

Import the public repository GPG keys.

1

curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

1

curl https://packages.microsoft.com/config/ubuntu/20.04/prod.list | sudo tee /etc/apt/sources.list.d/msprod.list

Update the sources list and run the installation command with the unixODBC developer package.

1
2


sudo apt-get update
sudo apt-get install mssql-tools unixodbc-dev

Add /opt/mssql-tools/bin/ to your PATH environment variable in a bash shell.

To make sqlcmd/bcp accessible from the bash shell for login sessions, modify your PATH in the ~/.bash_profile file with the following command:

1

echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile

To make sqlcmd/bcp accessible from the bash shell for interactive/non-login sessions, modify the PATH in the ~/.bashrc file with the following command:

1
2


echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
source ~/.bashrc

Connecting locally

Upon successful installation, we can connect to the database server and perform some operations

Run sqlcmd with parameters for your SQL Server name (-S), the user name (-U), and the password (-P). In this tutorial, you are connecting locally, so the server name is localhost. The user name is SA and the password is the one you provided for the SA account during setup.

1

sqlcmd -S localhost -U SA -P '<YourPassword>'

You can omit the password on the command line to be prompted to enter it.

If you later decide to connect remotely, specify the machine name or IP address for the -S parameter, and make sure port 1433 is open on your firewall.

If successful, you should get to a sqlcmd command prompt: 1>.

$ sqlcmd -S 127.0.0.1 -U SA -P 'Sup4Srcr7Pa$$';

Executing basic sql queries

In this section, we will explore using sqlcmd to create a new database, add data, and run a simple query.

Note: You must type GO on a new line to execute the commands.

To create a new database, use this:

1> CREATE DATABASE CitizixDB
2> GO

To get names of all the databases:

1> SELECT Name from sys.Databases
2> GO

CitizixDB

(5 rows affected)

Let us create a new table, Users, and insert new rows.

Switch context to the new CitizixDB database:

1> use CitizixDB
2> GO
Changed database context to 'CitizixDB'.

Create new table named Users:

1> CREATE TABLE Users (id INT, name NVARCHAR(50), age INT)
2> GO

Insert data into the new table:

          1 etowett                                                     72

To end your sqlcmd session, type QUIT:

1> QUIT

Conclusion

In this guide, we managed to install Ms SQL Server 2019 in an Ubuntu 20.04 server.
