安装和配置其他节点

您可以通过将 Tableau 添加到其他节点并创建分布式安装来扩展 Tableau Server 安装。本文介绍在其他节点上安装 Tableau Server 的一般步骤，并假定您已在初始节点上安装了 Tableau。有关在初始节点上安装 Tableau 的详细信息，请参阅安装 TSM。

如果要在多个节点上安装 Tableau Server，则应一次安装和配置一个节点。这样可以更轻松地对可能遇到的任何问题进行故障排除。

重要提示：如果可以通过应用挂起的更改完全完成该过程，则应添加和配置其他节点。通过应用挂起的更改添加节点而不完成可能会导致用户无法登录到 Tableau Server。

安装位置

Tableau Server 在群集中的所有节点上的安装位置必须相同。无论安装到默认位置还是非默认位置，都是如此。

• 使用 TSM Web 界面

• 使用 TSM 命令行管理平台

生成节点引导程序文件

1. 在浏览器中打开 TSM：

   https://<计算机名称>：8850

   有关详细信息，请参阅登录到 Tableau Services Manager Web UI。

2. 单击“配置”选项卡，然后在“添加节点”框中，单击“下载引导程序文件”。

   

   将创建引导程序文件并将其复制到本地计算机。

   从版本 2019.3 开始，默认情况下，引导程序文件中包含嵌入的凭据。如果您不希望凭据嵌入到引导程序文件中，请清除“在文件中包含临时凭据”选项。有关详细信息，请参阅新增功能中的 Tableau Server 中的新增功能和更改内容。如果要完全禁用在节点引导程序文件中包含嵌入式凭据的功能，可以为服务器设置配置选项。查看功能。PasswordlessBootstrapInit了解更多详情。

安装并初始化其他节点

在开始之前，请验证您的节点引导程序文件是否是最新的。例如，如果在生成引导程序文件后运行，则初始化将失败。tsm security regenerate-internal-tokens

1. Copy the original installer you used on the first computer along with the bootstrap file you generated and put them in a location accessible from the new computer you are adding Tableau Server to. This could be a mounted network share, or directly on the new computer.

2. If you are running a local firewall, then you need to configure firewall rules for all the nodes in the cluster. For more information, see Local firewall configuration.

3. On the new node, run the Tableau Server Setup program. This should be the same installer program you ran on the initial node to install Tableau Server. Accept the terms of the license agreement and click Next.

   The Install location must be the same on every node in the cluster.

   During installation you will be asked to select an installation type. Select Add additional node to existing Tableau Server cluster:

   

4. Click Next to continue.

   If you are prompted by Windows Defender Firewall, click Allow access. You may need to do this multiple times for the installation to complete.

5. In the installer, after the Tableau Server files are copied, you will be prompted to provide the bootstrap file and the name and password of the TSM administrator:

   

   Click Next to continue.

6. Enter the location of the bootstrap file, or click Browse to navigate to the location. If the bootstrap file does not include embedded credentials, or those credentials have expired, enter the TSM administrator username and password. These credentials must be the credentials of the user that you used during the installation process on the initial node.

7. A browser window opens and you are prompted to sign in to TSM. Enter the TSM administrator user name and password.

   If no browser window opens automatically, open a window and navigate to TSM:

   https://

8. In TSM, click Configuration.

   A message displays, telling you the node was added:

   

9. Click Continue.

Configure the additional node with Cluster Controller

1. Open TSM in a browser:

   https://<tsm-computer-name>:8850

   For more information, see Sign in to Tableau Services Manager Web UI.

2. Click the Configuration tab. A message should tell you that the new node was added.

   

   Click Continue to dismiss the message.

3. Cluster Controller is part of the minimum topology and is already selected. Each node must run Cluster Controller.

   If you only want to set the minimum topology for the node, go to Step 4 below. You might do this if you will be adding additional nodes and are not ready to configure this node beyond the minimum.

   If you want to add additional processes to the minimum topology, specify the processes that should run on the node. Do this by selecting the processes you want, or specifying the number of processes that should run on the node.

   For example, to add a Gateway and two instances of the Backgrounder on the node:

   The specific processes and process counts you set will depend on your organizational environment and needs. Some processes are added automatically when you add another process. For more information, see Configure Nodes and Tableau Server Processes.

   Note: The TSM Web UI limits you to a maximum of 8 instances of processes that allow you to select the number of instances. To configure more instances than this, use the command line and the command. For more information, see tsm topology set-process.TSM topology set-process

1. Select Gateway.

2. Set the Backgrounder count to 2.

   Adding Backgrounder to a node will also add an instance of Data Engine if one is not already on the node.

4. Click Pending Changes at the top of the page:

   

   If you are configuring a cluster with three or more nodes, a Coordination Service ensemble warning displays. You can continue. You will deploy a Coordination Service ensemble in a separate step.

5. 单击应用更改并重新启动并确认以确认重新启动 Tableau Server。

   在 Tableau Server 重新启动后，该节点将包含在所需的最低拓扑和您配置的任何其他进程中。

安装驱动程序

您需要安装驱动程序，以便 Tableau Server 可以连接到数据并运行数据提取。在运行以下任一进程的节点上安装这些驱动程序：

• VizQL Server （vizqlserver）

• Application Server （vizportal）

• 数据服务器（数据服务器）

• 后台程序（后台程序）

驱动程序和管理视图

如果要使用 Tableau Server 中的内置管理视图，还需要在运行上述任何进程的任何节点上安装 PostgreSQL 驱动程序。

有关详细信息，请参阅数据库驱动程序。

安装 Tableau 资源监视工具代理

如果使用资源监视工具监视 Tableau 服务器性能，则在添加新节点时，还必须安装资源监视工具。有关详细信息，请参阅 Tableau Server 拓扑更改。
