In this article, we will explain how to install SQL Server step by step.

在本文中，我们将逐步解释如何安装SQL Server。

入门 (Getting started)

You can download the SQL Server 2017 installer here.

您可以在此处下载SQL Server 2017安装程序。

You have 3 main options. The trial evaluation, Developer edition and Express edition.

您有3个主要选项。 试用版评估版为Developer版和Express版。

The main question is which SQL Server edition should I use?

主要问题是应该使用哪个SQL Server版本？

• The SQL Server trial evaluation is the free edition that includes all the features. If you want to check out any/all of the features, this is a complete version. It is a 180 days trial, but you can buy an Enterprise or Standard license later. Use this version if you plan to buy a license later. SQL Server试用版评估是免费版，其中包含所有功能。 如果您想签出任何/所有功能，则为完整版本。 试用期为180天，但您可以稍后购买企业版或标准版许可。 如果您打算以后购买许可证，请使用此版本。
• SQL Server Developer edition is free, but you cannot use it in production. For this tutorial, you can use any of them. I recommend this one if you use it for development purposes or for training purposes. It includes all the features also. SQL Server Developer版本是免费的，但是您不能在生产中使用它。 对于本教程，您可以使用其中任何一个。 如果您将其用于开发目的或用于培训目的，我建议您使用它。 它还包括所有功能。
• The SQL Server Express edition is free and can be used in production, but it has a limitation in Storage (10 GB) and it does not include several features (SQL Server Agent, DTA, etc.). I recommend this edition if you do not have too much disk space or resources in your machine. SQL Server Express版是免费的，可以在生产中使用，但是它在存储（10 GB）方面有一个限制，并且不包含几个功能（SQL Server代理，DTA等）。 如果您的计算机中没有太多的磁盘空间或资源，则建议使用此版本。

There are other editions like the SQL Server Standard and Web edition. They are cheaper versions than the enterprise. The Web edition contains the features necessary to work in a Web hosting environment. The Standard edition is like the Enterprise edition, but it has some limitations like the Transparent Data Encryption, Partition Table parallelism, mirrored backups, online indexing, etc. I recommend checking the features that are not included in this edition to check if it is a good idea to buy them to save money.

还有其他版本，例如SQL Server Standard和Web版本。 它们比企业版便宜。 Web版本包含在Web托管环境中工作所必需的功能。 标准版与企业版类似，但是它有一些限制，例如透明数据加密，分区表并行性，镜像备份，在线索引等。我建议检查此版未包含的功能以检查它是否是买它们可以省钱的好主意。

Once downloaded, run the setup file of the SQL Server installer. The Basic option will install mainly the Database Engine with basic components. We will use the Custom option to learn some other features included in SQL Server. Download Media is used to install later or to install in other machines:

下载后，运行SQL Server安装程序的安装文件。 基本选项将主要安装带有基本组件的数据库引擎。 我们将使用“自定义”选项来学习SQL Server中包含的其他一些功能。 下载媒体用于以后安装或在其他计算机上安装：

此外，它将显示GitHub ，其中包含示例数据库，代码示例等。

The installer will install in the Planning section. There are many nice resources here like the Hardware and Software requirements to verify if you have all the hardware and software requirements. You also have security documentation, System Configuration Checker, the Data Migration Assistant (DMA), Online installation documentation, Failover and Upgrading documentation:

安装程序将在“计划”部分中安装。 这里有很多不错的资源，例如硬件和软件需求，可用来验证您是否具有所有硬件和软件需求。 您还具有安全性文档，系统配置检查器，数据迁移助手（DMA），联机安装文档，故障转移和升级文档：

We will go to the Installation section and select the option New SQL Server stand-alone installation. Note that SQL Server Reporting Services is installed separately:

In the context of the Feature Selection, Data Engine Services is the database itself.

在功能选择的上下文中，数据引擎服务是数据库本身。

• Replication is useful if you want to replicate your data in another server or another SQL Server instance. 如果要在另一台服务器或另一台SQL Server实例中复制数据，则复制很有用。
• R or R或Python. SQL Server 2016 included the R Services. Now, you can have R and/or Python. Python 。 SQL Server 2016包括R服务。 现在，您可以拥有R和/或Python。
• Full-Text and Semantic Extractions for Search used for full-text queries. 全文和语义提取。

• PolyBase used to query NoSQL Data. PolyBase，用于查询NoSQL数据。
• Analysis Services is used in Business Intelligence (BI) to generate cubes to create Enterprise Reports with a multi-dimensional technology: Analysis Services在商业智能（BI）中用于生成多维数据集，以使用多维技术创建企业报告：

You have Machine Learning Services (In-Database) and Standalone. The first option is to install the SQL Server Database Engine. The Standalone does not require a database engine.

您拥有机器学习服务（数据库内）和独立服务器。 第一种选择是安装SQL Server数据库引擎。 独立服务器不需要数据库引擎。

Data Quality Client is to perform quality operations using standalone tools. In Integration Services we have the option to install Scale Out Master and Scale Out Worker. With this feature you can distribute the packages in different Servers to provide better performance. The master is the responsible for the operations and the Workers receive the tasks. Client tools backward compatibility includes tools to work with earlier SQL Server versions like deprecated tools, discontinued tools and breaking changes in SQL tools.

数据质量客户端将使用独立工具执行质量操作。 在Integration Services中，我们可以选择安装Scale Out Master和Scale Out Worker。 使用此功能，您可以将软件包分发到不同的服务器中，以提供更好的性能。 主人负责操作，工人接受任务。 客户端工具的向后兼容性包括可与早期SQL Server版本一起使用的工具 ，例如已弃用的工具 ， 已停产的工具以及SQL工具的重大更改 。

Client tools SDK contain resources for programmers.

客户端工具SDK包含供程序员使用的资源。

Distributed Replay Controller is the feature in charge to administer the distributed Replay clients. The Distribution Replay is used to capture a trace, verify performance, security, for upgrades or test environments it is like the SQL Profiler, but distributed Replay can trace multiple servers.

分布式重播控制器是负责管理分布式重播客户端的功能。 分发重播用于捕获跟踪，验证性能，安全性，用于升级或测试环境，就像SQL事件探查器一样，但是分布式重播可以跟踪多个服务器。

You can install the Distributed Replay client to simulate workloads.

您可以安装“分布式重播”客户端来模拟工作负载。

SQL Client Connectivity SDK will install SQL Server OLEBD and ODBC connectors that can be used to connect to SQL Server using.NET, Java, PHP or other programming languages.

SQL Client Connectivity SDK将安装SQL Server OLEBD和ODBC连接器，这些连接器可用于使用.NET，Java，PHP或其他编程语言连接到SQL Server。

Finally, the Master Data Services are used to organize your data into models, creates rules for the access to the data and control who is using it:

最后，主数据服务用于将数据组织到模型中，创建访问数据的规则并控制谁在使用数据：

If you select to install PolyBase, the setup will ask for the Oracle JRE. You can obtain the JRE installer in the following link.

如果选择安装PolyBase，则安装程序将要求提供Oracle JRE。 您可以通过以下链接获取JRE安装程序。

You can have multiple SQL Server instances in SQL Server in the same server. This can be useful to simulate and practice replications, mirroring or to have separate instances for different purposes. By default, you can install the default instance that is usually the Server computer name:

同一服务器上SQL Server中可以有多个SQL Server实例。 这对于模拟和实践复制，镜像或具有用于不同目的的单独实例非常有用。 默认情况下，您可以安装默认实例，通常是服务器计算机名称：

In PolyBase you can now install as a standalone instance or using a PolyBase scale-out group. The Scale-out group is used when you need to query massive data and you need to distribute the job across multiple SQL Server instances. This option requires to enable ports and enable the MSDTC:

现在，您可以在PolyBase中作为独立实例安装，也可以使用PolyBase横向扩展组安装 。 当您需要查询海量数据并且需要在多个SQL Server实例之间分配作业时，可以使用横向扩展组。 此选项需要启用端口并启用MSDTC：

There are account names created automatically for each service. It is a good practice to keep them. Do not grant administrative privileges to these accounts unless there is no other choice:

有为每个服务自动创建的帐户名。 保留它们是一个好习惯。 除非没有其他选择，否则不要向这些帐户授予管理特权：

There are two options in SQL Server to authenticate. Windows authentication will use the Windows Account to authenticate in SQL. Mixed Mode allows creating internal logins and passwords inside SQL Server. You can Add accounts here using the Add Current User or by pressing the Add button:

SQL Server中有两个选项可以进行身份​​验证。 Windows身份验证将使用Windows帐户在SQL中进行身份验证。 混合模式允许在SQL Server内部创建内部登录名和密码。 您可以使用“添加当前用户”或按“添加”按钮在此处添加帐户：

In the Data Directories tab, you can choose the location of your data file and log file. It is a good practice to have them in separated drives to improve performance and increase security for disaster recovery.

在“数据目录”选项卡中，您可以选择数据文件和日志文件的位置。 将它们放在单独的驱动器中是一个好习惯，以提高性能并提高灾难恢复的安全性。

The Analysis Services Configuration allows installing a Multidimensional and Data Mining Mode. This is a multidimensional cube that allows creating fast queries for enterprise reports. Another option is to Install Tabular Mode. The Tabular databases are dependent on the RAM. If your database will have several TB of information, the Multidimensional option is better. If you require Data Mining services, the Multidimensional option is better. For more information about Multidimensional vs Tabular Models, refer to this link.

Analysis Services配置允许安装多维和数据挖掘模式。 这是一个多维多维数据集，它允许为企业报告创建快速查询。 另一种选择是安装表格模式。 表格数据库取决于RAM。 如果您的数据库将具有数TB的信息，则“多维”选项会更好。 如果需要数据挖掘服务，则“多维”选项更好。 有关多维模型和表格模型的更多信息，请参考此链接 。
