Microsoft SQL Server is a powerful relational database management system (RDBMS) widely used for enterprise-grade database applications. Though it's traditionally associated with Windows, SQL Server can also be installed on Linux distributions like Debian. In this guide, we will walk you through how to install Microsoft SQL Server on Debian 12. Hosting SQL Server on a WindowsVPS ensures better performance and scalability using the dedicated resources of a VPS server.

Step 1: Update Your VPS Server

Before installing SQL Server, ensure that your VPS server is up to date. Run the following commands to update your Debian system:

sudo apt update && sudo apt upgrade -y

By using a WindowsVPS, you can take advantage of dedicated CPU, memory, and storage resources, ensuring your SQL Server installation performs optimally, even for high-demand database applications.

Step 2: Import the Microsoft GPG Key

Microsoft provides official repositories for installing SQL Server on Linux. First, you need to import the Microsoft GPG key:

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | sudo tee /etc/apt/trusted.gpg.d/microsoft.asc

Step 3: Add the SQL Server Repository

Next, add the SQL Server repository for Debian 12 by running the following commands:

sudo add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/debian/12/prod.list)"

Update the package list after adding the repository:

sudo apt update

Step 4: Install Microsoft SQL Server

Now, you can install Microsoft SQL Server using the following command:

sudo apt install -y mssql-server

After the installation is complete, run the following command to start the setup process:

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

During the setup, you will be prompted to choose the SQL Server edition (e.g., Evaluation, Developer, Express) and set the SA (system administrator) password. Choose the edition that best suits your needs and make sure to set a strong SA password.

Step 5: Verify SQL Server Installation

Once the setup is complete, verify that SQL Server is running by checking the service status:

systemctl status mssql-server --no-pager

If the service is running, you should see output indicating that the mssql-server service is active.

Step 6: Install SQL Server Tools (Optional)

To interact with SQL Server, you can install the SQL Server command-line tools such as sqlcmd and bcp. First, add the Microsoft repository for SQL Server tools:

sudo add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/debian/12/prod.list)"
sudo apt update

Then install the tools with:

sudo apt install mssql-tools unixodbc-dev -y

To make the tools accessible from any location, add them to your PATH environment variable:

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

Step 7: Allow Remote Connections (Optional)

If you want to access SQL Server remotely, you need to open the necessary ports. SQL Server typically listens on port 1433 by default. Allow traffic on this port using the following firewall commands:

sudo ufw allow 1433/tcp
sudo ufw reload

Step 8: Optimize Your VPS Server for SQL Server

Running Microsoft SQL Server on a WindowsVPS allows you to leverage the dedicated resources of a VPS server for your database applications. A VPS provides better performance, especially when dealing with high-concurrency transactions, large databases, and mission-critical applications. As your database grows, you can scale your VPS resources, ensuring that SQL Server continues to perform efficiently under heavy workloads.

Conclusion

Installing Microsoft SQL Server on Debian 12 allows you to take advantage of a powerful relational database system on a Linux environment. Hosting SQL Server on a WindowsVPS ensures your database has the performance, scalability, and reliability needed for enterprise-grade applications.
