Instance Configuration

You can have multiple instances of the SQL Server running in the system. Each must have its own instance name

You can have one default instance. The default instance name is MSSQLSERVER. If you choose this, then you can then use your computer name (or IP address) to connect to that instance

All other instances must be named. You can then use name /<instanceName> to connect to that instance.

Choose the default instance.

Example of creating the Named Instance. You need to use the name /SQL2019 to connect to SQL Server

Server Configuration

The Next window list the various services, which you can configure. This list of services displayed here depends on the Features selected.

Here, you need to specify the Account Name, Password and startup type for each service.

Keep the defaults and click on Next

Database Engine Configuration

Here you are asked to configure the database by providing the authentication mode & password for the SA user.

Under Authentication Mode, you have two options.

Windows Authentication

In this mode, the windows user is automatically recognized by SQL Server. The Windows security identifier (SID) is passed from Windows to SQL Server. The SQL Server does not store any user information and trusts the Windows user. The SA user gets disabled when you use this

Mixed Mode ( Windows Authentication and SQL Server authentication Mode)

In this mode, along with the Windows Users, the SQL Server also stores the user name & password in the database. In this scenario, you can connect to SQL Server either using the Windows account and using the user name/password stored in SQL Server itself

Choose Mixed Mode.

You have to enter the SA user password.

Also, click on Add Current User to add the Current Logged in User to SQL Server

You can also change the default folders used by the SQL Server from the tab Data Directories

Other Configuration

Depending on the Features that you have selected, you will be presented with the configuration option for each feature.
