Installing Microsoft SQL Server on Linux

It’s common for organizations of all sizes to choose Microsoft SQL Server as their preferred DBMS. SQL Server, which has previously only been offered for Windows, is now now accessible for Linux, giving businesses who choose Linux an additional platform on which to build their infrastructure. In this post, we’ll show you how to set up Microsoft SQL Server on Linux from scratch.

Why Install SQL Server on Linux?

Installing SQL Server on Linux may be useful for a number of reasons. Linux is often less expensive than Windows, so switching to it might help you save money there.

  • At least 2GB of available memory
  • At least 6GB of available disk space
  • An active internet connection

Step 1: Download the Microsoft SQL Server Package for Linux

The first thing you need to do in order to install SQL Server on Linux is to get the package that corresponds to your specific Linux system. Microsoft offers a repository for SQL Server packages that may be installed on your machine by executing the following instructions in the appropriate order:

sudo curl -o /etc/yum.repos.d/mssql-server.repo
sudo yum install -y mssql-server

For Ubuntu, you can use the following commands:

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

For SUSE Linux Enterprise, you can use the following commands:

sudo zypper addrepo -fc
sudo zypper install -y mssql-server

Step 2: Run the SQL Server Installation Wizard

After you have finished downloading the SQL Server package for your Linux distribution, you can begin the installation process by entering the following line into the command prompt:

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

This will start the installation wizard, which will walk you through the steps of configuring SQL Server while it is being installed. Over the course of the installation process, you will be required to choose a default language for the server as well as to specify a password for the SQL Server system administrator (sa) account.

These tools include the SQL Server command-line utilities and the mssql-tools package. Both of these tools are provided by Microsoft. You may install these tools by use the commands that are shown below:

sudo yum install -y mssql-tools unixODBC-devel
sudo apt-get install -y mssql-tools unixODBC-dev
sudo zypper install -y mssql-tools unixODBC-devel

Step 4: Verify the SQL Server Installation

Using the following command after the installation procedure has been completed will allow you to confirm that SQL Server is functioning properly.

systemctl status mssql-server --no-pager

The current status of the SQL Server service will be shown after this command is executed. If everything is functioning as it should, you should be able to see a notice stating that the service is up and operating.

active and running. If there are any issues, you can check the SQL Server error logs, which are located in the /var/opt/mssql/log directory.

Step 5: Configure SQL Server Firewall Rules

By default, SQL Server listens on TCP port 1433. In order to establish a connection to the SQL Server instance, you may have to adjust the settings on your firewall to permit inbound traffic on this port. The procedure for establishing firewall rules differs from one Linux distribution and firewall software to another, depending on which you’re using. The following are some examples:

For firewalld (used by CentOS, Red Hat Enterprise Linux, and Fedora), you can use the following commands to open TCP port 1433:

sudo firewall-cmd --zone=public --add-port=1433/tcp --permanent
sudo firewall-cmd --reload

For ufw (used by Ubuntu), you can use the following commands to open TCP port 1433:

sudo ufw allow 1433/tcp

For iptables (used by many Linux distributions), you can use the following command to open TCP port 1433:

sudo iptables -A INPUT -p tcp --dport 1433 -j ACCEPT
