Description

Why install Microsoft SQL Server?

SQL Server delivers a battle-tested relational engine, high-availability options, integrated analytics, and strong tooling. Installing it locally lets you prototype, test, and run production workloads without relying on external services.

How do I install SQL Server on Ubuntu 22.04?

Run the official Microsoft repository script, install the mssql-server package, then complete the setup wizard to pick an edition and set the sa password.

curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
sudo add-apt-repository "$(curl https://packages.microsoft.com/config/ubuntu/22.04/mssql-server-2022.list)"
sudo apt-get update
sudo apt-get install -y mssql-server
sudo /opt/mssql/bin/mssql-conf setup # choose Developer edition

What firewall port must remain open?

Keep TCP 1433 open so applications and tools such as Galaxy can connect.

How do I install SQL Server on Windows 11?

Download the Developer or Express edition ISO, run setup.exe, and follow the wizard. Select Database Engine Services, Mixed Mode authentication, and specify the sa password.

Which edition should I choose?

Developer edition is feature-complete and free for dev/test; Express is free for small workloads but limited to 10 GB per database.

How do I run SQL Server in Docker?

docker pull mcr.microsoft.com/mssql/server:2022-latest
docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Str0ngP@ss!" \
-p 1433:1433 --name sql2022 -d mcr.microsoft.com/mssql/server:2022-latest

The container starts in seconds and persists data in the writable layer. Mount a host volume for durability.

What post-install steps should I run?

Install client tools (sqlcmd, Azure Data Studio), enable remote connections, configure backups, and create a starter ecommerce database.

sqlcmd -S localhost -U sa -P "Str0ngP@ss!" -Q "CREATE DATABASE ecommerce;"

Best practices after installation

Harden authentication, enforce TLS, schedule full/diff/log backups, and monitor resource usage. Document connection strings for teammates.

Common mistakes and how to fix them

Wrong edition selected: Re-run mssql-conf setup (Linux) or the installer (Windows) to switch. Weak sa password: Use at least 8 chars, 3 character classes, and no dictionary words.

Frequently asked questions

Is SQL Server free?

Developer and Express editions are free. Standard and Enterprise require licenses.

Can I run SQL Server and PostgreSQL on the same host?

Yes, they listen on different ports. Watch RAM and I/O usage.

How do I uninstall SQL Server on Ubuntu?

Run sudo apt-get purge mssql-*, remove the repository file, and delete /var/opt/mssql.

How to install SQLServer in PostgreSQL Syntax


Linux (APT):
  sudo apt-get install -y mssql-server [mssql-tools] [optional-components]
  sudo /opt/mssql/bin/mssql-conf setup --edition [Developer|Express|Enterprise] --accept-eula
Windows (Setup CLI):
  setup.exe /Q /ACTION=Install /FEATURES=SQLENGINE /INSTANCENAME=MSSQLSERVER \
           /SECURITYMODE=SQL /SAPWD=<StrongPwd> /IACCEPTSQLSERVERLICENSETERMS
Docker:
  docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=<StrongPwd>" -p 1433:1433 \
           --name sql2022 -d mcr.microsoft.com/mssql/server:2022-latest
Post-install example (ecommerce context):
  sqlcmd -S localhost -U sa -P <StrongPwd> -Q "CREATE DATABASE ecommerce; USE ecommerce;\n  CREATE TABLE Customers(id INT PRIMARY KEY, name NVARCHAR(100), email NVARCHAR(255), created_at DATETIME);\n  CREATE TABLE Orders(id INT PRIMARY KEY, customer_id INT, order_date DATE, total_amount MONEY);"

Common Mistakes

Skipping the setup wizard on Linux. Without running "mssql-conf setup", the service starts but rejects logins because the edition and SA password were never configured. Always run the wizard immediately after installing the package.
Using a weak SA password. SQL Server enforces complexity but many users still pick trivial phrases. A rejected password halts installation. Choose 8+ characters, mix upper, lower, digits, and symbols.
