本地数据网关On-premises data gateway

本地数据网关的作用好似一架桥,提供本地数据(不在云中的数据)与 Power BI、Microsoft Flow、逻辑应用以及 PowerApps 服务之间快速且安全的数据传输。The On-premises data gateway acts as a bridge, providing quick and secure data transfer between on-premises data (data that is not in the cloud) and the Power BI, Microsoft Flow, Logic Apps, and PowerApps services.

你可以同时将单个网关与不同的服务一起使用。You can use a single gateway with different services at the same time. 如果使用的是 Power BI 和 PowerApps,可以对它们使用同一个网关。If you are using Power BI as well as PowerApps, a single gateway can be used for both. 它依赖于你登录的帐户。It is dependent on the account you sign in with.


本地数据网关在所有模式下实现数据压缩和传输加密。The On-premises data gateway implements data compression, and transport encryption, in all modes.

下载并安装本地数据网关Download and install the On-premises data gateway

若要下载网关,请选择“下载”菜单下的“数据网关”。To download the gateway, select Data Gateway under the Downloads menu. 下载本地数据网关Download the On-premises data gateway.

请注意:通过重新安装网关来更新本地数据网关,如本部分中所述。Note that updating the On-premises data gateway is achieved by reinstalling the gateway, as described in this section. 更新网关(通过重新安装)时,会保留现有的网关设置。When updating the gateway (by reinstalling), your existing gateways settings are retained.

安装本地数据网关Install the On-premises data gateway

在计算机上安装和运行数据网关。The data gateway installs and runs on your computer. 最好可以在持续运行的计算机上安装网关。It is best to install the gateway on a machine that can be left running all the time.


只有 64 位 Windows 操作系统才支持该网关。The gateway is supported only on 64-bit Windows operating systems.

对于 Power BI,首先你需要选择网关的模式。For Power BI, the first choice you have to make is the mode of the gateway.

  • 本地数据网关: 在此模式中,多个用户可以共享和重复使用网关。On-premises data gateway: Multiple users can share and reuse a gateway in this mode. Power BI、PowerApps、Flow 或逻辑应用可以使用此网关。This gateway can be used by Power BI, PowerApps, Flow or Logic Apps. 对于 Power BI,这包括支持计划刷新和 DirectQueryFor Power BI, this includes support for both schedule refresh and DirectQuery
  • 个人: 此模式仅适用于 Power BI,可以作为无需任何管理员配置的个人身份使用。Personal: This is for Power BI only and can be used as an individual without any administrator configuration. 仅可用于按需刷新和计划刷新。This can only be used for on-demand refresh and schedule refresh. 选择此模式后,便会开始安装个人网关。This selection launchs installation of the personal gateway.

无论安装上述哪一种模式的网关,都需要注意以下几点:There are a few things to note about insalling either mode of the gateway:

  • 两个网关都需要 64 位 Windows 操作系统both gateways require 64-bit Windows operating systems
  • 网关不能安装在域控制器上gateways can’t be installed on a domain controller
  • 同一台计算机上最多可以安装两个本地数据网关,分别在两个模式(个人和标准)下运行。you can install up to two On-premises data gateways on the same computer, one running in each mode (personal and standard).
  • 在同一台计算机上,不能有多个网关在相同模式下运行。you cannot have more than one gateway running in the same mode on the same computer.
  • 可以在不同计算机上安装多个本地数据网关,并通过同一 Power BI 网关管理界面管理所有这些网关(个人网关除外,见下一注意点)you can install multiple On-premises data gateways on different computers, and manage them all from the same Power BI gateway management interface (excluding personal, see the following bullet point)
  • 只能为每个 Power BI 用户运行一个个人模式网关。You can only have one Personal mode gateway running for each Power BI user. 如果为同一用户安装另一个人模式网关,即使是在其他计算机上,最新安装也会替换现有旧安装。If you install another Personal mode gateway for the same user, even on a different computer, the most recent installation replaces the existing previous installation.


以下是安装网关之前需要考虑的一些事项。Here are a few things to consider before installing the gateway.

  • 如果要在笔记本电脑上安装,但是笔记本电脑已关闭,没有连接到 Internet,或处于休眠状态,网关将不起作用,云服务中的数据将不会与本地数据同步。If you are installing on a laptop, and your laptop is turned off, not connected to the internet, or asleep the gateway won’t work and the data in the cloud service will not be synchronized with your on-premises data.
  • 如果计算机已连接到无线网络,网关运行可能较慢,这会导致云服务中的数据与本地数据同步需要更长的时间。If your machine is connected to a wireless network, the gateway may perform more slowly which will cause it to take longer to synchronize the data in the cloud service with your on-premises data.

安装网关后,需要使用工作或学校帐户登录。Once the gateway is installed, you will need to sign in with your work or school account.


登录后,必须选择配置新的网关,或迁移、还原或接管现有网关。After you are signed in, you will have the option to configure a new gateway, or to migrate, restore, or take over an existing gateway.


配置新网关Configure a new gateway

  1. 输入网关“名称”Enter a name for the gateway
  2. 输入“恢复密钥”。Enter a recovery key. 此恢复密钥至少应为 8 个字符。This has to be a minimum of 8 characters.
  3. 选择“配置”。Select Configure.


如果你需要迁移、还原或接管网关,则需要恢复密钥。The recovery key will be needed if you ever need to migrate, restore or take over a gateway. 请确保将此密钥保存在安全的位置。Be sure to keep this key in a safe place.


迁移、还原或接管现有网关Migrate, restore or take over an existing gateway

你需要选择想要恢复的网关,并提供用于首次创建网关的恢复密钥。You will need to select the gateway you want to recover and supply the recovery key that was used to first create the gateway.

连接本地数据网关On-premises data gateway connected

配置网关后,可使用它来连接到本地数据源。Once the gateway is configured, you will be able to make use of it to connect to on-premises data sources.

如果是 Power BI 网关,则需要将你的数据源添加到 Power BI 服务中的网关内。If the gateway is for Power BI, you will need to add your data sources to the gateway within the Power BI service. 在“管理网关”区域中完成此操作。This is done within the Manage gateways area. 可以参阅与管理数据源相关的文章,了解详细信息。You can refer to the manage data sources articles for more information.

对于 PowerApps,则需要为受支持数据源的定义连接选择网关。For PowerApps, you will need to select a gateway for a defined connection for supported data sources. 对于 Flow 和逻辑应用,可在进行本地连接时使用此网关。For Flow and Logic Apps, this gateway is ready to be used with your on-premises connections.

在个人模式下安装网关Install the gateway in personal mode


网关的个人版本仅适用于 Power BI。The Personal version of gateway only works with Power BI.

安装个人网关后,你将需要启动 Power BI Gateway - Personal 配置向导After the personal gateway is installed, you will need to launch the Power BI Gateway - Personal Configuration Wizard.

然后你需要登录到 Power BI 以使用云服务注册网关。You will then need to sign into Power BI to register the gateway with the cloud service.

你还需要提供 Windows 服务运行需要的 Windows 用户名和密码。You will also need to supply the windows user name and password that the windows service will run as. 你可以自己指定一个不同的 Windows 帐户。You can specify a different Windows account from your own. 网关服务将使用此帐户运行。The gateway service will run using this account.

安装完成后,将需要转到 Power BI 中的数据集并确保已为本地数据源输入了凭据。After the installation is complete, you will need to go to your datasets within Power BI and make sure credentials are entered for your on-premises data sources.

在云中存储加密凭据Storing encrypted credentials in the cloud

将数据源添加到网关时,需要为该数据源提供凭据。When you add a data source to the gateway, you need to provide credentials for that data source. 将使用这些凭据运行对数据源的所有查询。All queries to the data source will run using these credentials. 云中存储凭据之前,使用非对称加密安全地加密凭据,以阻止在云中对其进行解密。The credentials are encrypted securely, using asymmetric encryption so that they cannot be decrypted in the cloud, before they are stored in the cloud. 将凭据发送到运行网关的计算机,以便在访问数据源时对其进行本机解密。The credentials are sent to the machine, running the gateway, on-premises where they are decrypted when the data sources are accessed.

登录帐户Sign in account

用户将使用工作或学校帐户登录。Users will sign in with either a work or school account. 这是你的组织帐户。This is your organization account. 如果你注册了 Office 365 产品/服务,但没有提供实际的工作电子邮件,则可能类似于 nancy@contoso.onmicrosoft.com。If you signed up for an Office 365 offering and didn’t supply your actual work email, it may look like nancy@contoso.onmicrosoft.com. 你在云服务中的帐户存储于 Azure Active Directory (AAD) 中的租户内。Your account, within a cloud service, is stored within a tenant in Azure Active Directory (AAD). 在大多数情况下,你的 AAD 帐户的 UPN 将与电子邮件地址匹配。In most cases, your AAD account’s UPN will match the email address.

Windows 服务帐户Windows Service account

本地数据网关配置为使用 NT SERVICE\PBIEgwService 作为 Windows 服务登录凭据。The On-premises data gateway is configured to use NT SERVICE\PBIEgwService for the Windows service logon credential. 默认情况下,它有权作为服务登录。By default, it has the right of Log on as a service. 这位于正在安装网关的计算机的上下文中。This is in the context of the machine that you are installing the gateway on.


如果选择了个人模式,则需单独配置 Windows 服务帐户。If you selected personal mode, you configure the Windows service account separately.

这不是用于连接到本地数据源的帐户。This is not the account used to connect to on-premises data sources. 也不是登录到云服务的工作或学校帐户。This is also not your work or school account that you sign in to cloud services with.

如果你由于身份验证遇到有关代理服务器的问题,你可能需要将 Windows 服务帐户更改为域用户或托管服务帐户。If you encounter issues with your proxy server, due to authentication, you may want to change the Windows service account to a domain user or managed service account. 可以在代理配置 中了解如何更改帐户。You can learn how to change the account in proxy configuration.


网关将创建与 Azure 服务总线的出站连接。The gateway creates an outbound connection to Azure Service Bus. 它可在以下出站端口上进行通信:TCP 443(默认)、5671、5672、9350 至 9354。It communicates on outbound ports: TCP 443 (default), 5671, 5672, 9350 thru 9354. 网关不需要入站端口。The gateway does not require inbound ports. 了解详细信息Learn more

建议你将防火墙中数据区域的 IP 地址列入白名单。It is recommended that you whitelist the IP addresses, for your data region, in your firewall. 可以下载 Microsoft Azure 数据中心 IP 列表You can download the Microsoft Azure Datacenter IP list. 此列表每周更新。This list is updated weekly. 网关使用 IP 地址以及完全限定的域名 (FQDN) 与 Azure 服务总线进行通信。The gateway will communicate with Azure Service Bus using the IP address along with the fully qualified domain name (FQDN). 如果使用 HTTPS 强制网关进行通信,则网关将仅使用 FQDN,如果使用 IP 地址则不会进行通信。If you are forcing the gateway to communicate using HTTPS it will strictly use FQDN only, and no communication will happen using IP addresses.


Azure 数据中心 IP 列表中的 IP 地址以 CIDR 表示法列出。The IP Addresses listed in the Azure Datacenter IP list are in CIDR notation. 例如, 并不意味着 至。For example, does not mean thru 了解有关 CIDR 表示法的详细信息。Learn more about the CIDR notation.

下面是网关使用的完全限定的域名的列表。Here is a listing of the fully qualified domain names used by the gateway.

访问 visualstudio.com 或 visualstudioonline.com 的流量用于应用见解,而非网关作业所需。Traffic going to visualstudio.com or visualstudioonline.com are for app insights and are not required for the gateway to function.

强制 HTTPS 与 Azure 服务总线通信Forcing HTTPS communication with Azure Service Bus

可以使用 HTTPS 替代直接 TCP,以强制网关与 Azure 服务总线通信。You can force the gateway to communicate with Azure Service Bus using HTTPS instead of direct TCP. 这可能会对性能产生影响。This may have an impact on performance. 若要执行此操作,请通过将值从 AutoDetect 更改为 Https 来修改 Microsoft.PowerBI.DataMovement.Pipeline.GatewayCore.dll.config 文件,如紧接本段后面的代码片段中所示。To do so, modify the Microsoft.PowerBI.DataMovement.Pipeline.GatewayCore.dll.config file by changing the value from AutoDetect to Https, as shown in the code snippet directly following this paragraph. 默认情况下,此文件位于 C:\Program Files\On-premises data gatewayThat file is located (by default) at C:\Program Files\On-premises data gateway.

<setting name="ServiceBusSystemConnectivityModeString" serializeAs="String">

ServiceBusSystemConnectivityModeString 参数的值区分大小写。The value for the ServiceBusSystemConnectivityModeString parameter is case sensitive. 有效值为 AutoDetect 和 Https。Valid values are AutoDetect and Https.

或者,从 2017 年 3 月版本开始,用户可以使用网关用户界面来强制网关采用此行为。Alternatively, you can force the gateway to adopt this behavior using the gateway user interface, beginning with the March 2017 release. 在网关用户界面中,选择“网络”,然后将“Azure 服务总线连接模式”切换至“启用”。In the gateway user interface select Network, then toggle the Azure Service Bus connectivity mode to On.

更改后,在选择“应用”(该按钮仅在做出更改时出现)后,网关 Windows 服务 将自动重启,从而使更改生效。Once changed, when you select Apply (a button that only appears when you make a change), the gateway Windows service restarts automatically, so the change can take effect.

可以通过选择“服务设置”,然后选择“立即重启”从用户界面对话框中重启网关 Windows 服务 以供将来参考之用。For future reference, you can restart the gateway Windows service from the user interface dialog by selecting Service Settings then select Restart Now.

对 TLS 1.1/1.2 的支持Support for TLS 1.1/1.2

自 2017 年 8 月更新起,本地数据网关默认使用传输层安全 (TLS) 1.1 或 1.2 与 Power BI 服务进行通信。With the August 2017 update and beyond, the On-premises data gateway uses Transport Layer Security (TLS) 1.1 or 1.2 to communicate with the Power BI service by default. 以前版本的本地数据网关默认使用 TLS 1.0。Previous versions of the On-premises data gateway use TLS 1.0 by default. 2018 年 3 月 15 日,将不再支持 TLS 1.0,包括使用 TLS 1.0 与 Power BI 服务进行交互的网关功能。因此,届时必须将本地数据网关安装升级到 2017 年 8 月版或更高版本,才能确保网关可以继续正常运行。On March 15th 2018, support for TLS 1.0 will end, including the gateway's ability to interact with the Power BI service using TLS 1.0, so by then you must upgrade your On-premises data gateway installations to the August 2017 release or newer to ensure your gateways continue to operate.

值得注意的是,TLS 1.0 在 11 月 1 日之前仍受本地数据网关支持,并由网关用作回退机制。It's important to note that TLS 1.0 is still supported by the On-premises data gateway prior to November 1st, and is used by the gateway as a fallback mechanism. 要确保所有网关流量使用 TLS 1.1 或 1.2(并防止在网关上使用 TLS 1.0),必须在运行网关服务的计算机上添加或修改以下注册表项:To ensure all gateway traffic uses TLS 1.1 or 1.2 (and to prevent the use of TLS 1.0 on your gateway), you must add or modify the following registry keys on the machine running the gateway service:



添加或修改这些注册表项会将更改应用于所有 .NET 应用程序。Adding or modifying these registry keys applies the change to all .NET applications. 有关影响其他应用程序的 TLS 的注册表更改的信息,请参阅传输层安全性 (TLS) 注册表设置For information about registry changes that affect TLS for other applications, see Transport Layer Security (TLS) registry settings.

如何重启网关How to restart the gateway

网关作为一项 Windows 服务运行。The gateway runs as a windows service. 像任何 Windows 服务一样,你可以启动和停止它。You can start and stop it like any windows service. 有多种方法可以执行此操作。There are multiple ways to do this. 下面是你可以如何从命令提示符执行此操作。Here is how you can do it from the command prompt.

  1. 在运行网关的计算机上,启动管理员命令提示符。On the machine where the gateway is running, launch an admin command prompt.

  2. 使用以下命令停止服务。Use the following command to stop the service.

    net stop PBIEgwServicenet stop PBIEgwService

  3. 使用以下命令启动服务。Use the following command to start the service.

    net start PBIEgwServicenet start PBIEgwService

网关的工作原理How the gateway works


让我们首先看一下当用户与连接到本地数据源的元素交互时,会发生什么情况。Let’s first look at what happens when a user interacts with an element connected to an on-premises data source.


对于 Power BI,需要配置网关的数据源。For Power BI, you will need to configure a data source for the gateway.

  1. 云服务将创建查询以及本地数据源的加密凭据,并将其发送到队列中以让网关进行处理。A query will be created by the cloud service, along with the encrypted credentials for the on-premises data source, and sent to the queue for the gateway to process.
  2. 网关云服务将分析该查询,并将请求推送到 Azure 服务总线The gateway cloud service will analyze the query and will push the request to the Azure Service Bus.
  3. 本地数据网关将为挂起的请求轮询 Azure 服务总线The On-premises data gateway polls the Azure Service Bus for pending requests.
  4. 网关获取查询、解密凭据并使用这些凭据连接到数据源。The gateway gets the query, decrypts the credentials and connects to the data source(s) with those credentials.
  5. 网关将查询发送到数据源执行。The gateway sends the query to the data source for execution.
  6. 执行的结果从数据源发出,返回到网关,然后到云服务上。The results are sent from the data source, back to the gateway, and then onto the cloud service. 然后,服务将使用该结果。The service then uses the results.

限制和注意事项Limitations and Considerations

租户级别管理Tenant level administration

目前没有一个集中位置供租户管理员在其中管理其他用户已安装并配置的所有网关。There is currently no single place where tenant administrators can manage all the gateways that other users have installed and configured. 如果你是租户管理员,建议你请求组织中的用户将你添加为他们所安装的每个网关的管理员。If you’re a tenant administrator, we recommend that you ask the users in your organization to add you as an administrator to every gateway they install. 这样你便可以通过“网关设置”页或通过 PowerShell 命令管理组织中的所有网关。This allows you to manage all the gateways in your organization through the Gateway Settings page or through PowerShell commands.

启用出站 Azure 连接Enabling outbound Azure connections

本地数据网关依赖 Azure 服务总线提供云连接,并相应地建立到其关联 Azure 区域的出站连接。The On-premises data gateway relies on Azure Service Bus for cloud connectivity and correspondingly establishes outbound connections to its associated Azure region. 默认情况下,这是你的 Power BI 租户的位置。By default, this is the location of your Power BI tenant. 查看我的 Power BI 租户位于何处?See Where is my Power BI tenant located? 如果防火墙阻止出站连接,则必须配置防火墙,使其允许从本地数据网关到其关联 Azure 区域的出站连接。If a firewall is blocking outbound connections, you must configure the firewall to allow outbound connections from the On-premises data gateway to its associated Azure region. 请参阅 Microsoft Azure 数据中心 IP 范围详细了解每个 Azure 数据中心 IP 地址范围。See Microsoft Azure Datacenter IP Ranges for details about the IP address ranges of each Azure data center.


IP 地址范围可能随时间而变化,因此请确保定期下载最新信息。The IP address ranges might change over time, so make sure you download the latest information on a regular basis.


如果在安装和配置网关时遇到问题,请务必参阅本地数据网关疑难解答If you’re having trouble when installing and configuring a gateway, be sure to see Troubleshooting the On-premises data gateway. 如果你认为你的防火墙有问题,请参阅故障排除文章中的防火墙或代理部分。If you think you are having an issue with your firewall, see the firewall or proxy section in the troubleshooting article.

如果你认为网关遇到代理问题,请参阅为 Power BI Gateway 配置代理服务器设置If you think you are encountering proxy issues, with the gateway, see Configuring proxy settings for the Power BI gateways.
