To install SQL Server, follow these steps:
Review installation requirements, system configuration checks, and security considerations for a SQL Server installation.
Run SQL Server Setup to install or upgrade to a later version.
Use SQL Server utilities to configure SQL Server.
Regardless of the installation method, you are required to confirm acceptance of the software license terms as an individual or on behalf of an entity, unless your use of the software is governed by a separate agreement such as a Microsoft volume licensing agreement or a third-party agreement with an ISV or OEM.
The license terms are displayed for review and acceptance in the Setup user interface. Unattended installations (using the /Q or /QS parameters) must include the /IAcceptSQLServerLicenseTerms parameter. You can review the license terms separately at Microsoft Software License Terms.
Depending on how you received the software (for example, through Microsoft volume licensing), your use of the software may be subject to additional terms and conditions.
