如果您的应用程序需要通过 ODBC 访问外部数据库，可在 Plesk 中创建所需的 ODBC 连接。您在创建 ODBC 连接后，可自定义该应用程序使用该 ODBC 连接，以访问数据库中的信息。

注意，该数据库不一定是外部数据库，ODBC 也可用于访问本地数据库。

ODBC data sources can be managed at two levels:

  • Server level — data sources available to all domains on the server. Managed in Tools & Settings > ODBC Data Sources.

  • Domain level — data sources available to a specific domain only. Managed in Websites & Domains > ODBC Data Sources.

Plesk supports both 32-bit and 64-bit data sources. When creating a data source, you can select the platform (32-bit or 64-bit) based on your application’s requirements. The default is 64-bit.

备注

If you are upgrading from an earlier version of Plesk, the plesk bin dsn CLI command now defaults to managing 64-bit data sources. If you need to manage 32-bit data sources via CLI, use the -bit 32 option explicitly.

ODBC Drivers

Plesk for Windows includes built-in support for the following 64-bit ODBC drivers:

  • SQL 服务器

  • ODBC Driver 17 for SQL Server

  • MySQL ODBC 9.7

To use additional ODBC drivers, install them manually on the server. After installation, go to Tools & Settings > Server Components and click Refresh so that Plesk recognizes the newly installed drivers.

Managing Server-Level ODBC Data Sources

Server-level ODBC data sources are available to all domains on the server.

To create a new server-level ODBC data source:

  1. Go to Tools & Settings and click ODBC Data Sources.

  2. 点击 添加 ODBC DSN.

  3. 在相应字段指定 ODBC 连接名称和描述。

  4. In the Platform field, select 32-bit or 64-bit depending on your application’s requirements.

  5. 在 驱动程序 字段选择所需驱动程序。

  6. 点击 创建 ODBC DSN.

  7. Choose the appropriate options on the driver configuration screen. Typically, you have to specify the database path, user credentials, and other connection options depending on the selected driver.

  8. Click Test connection to check whether the connection will function properly with the provided settings.

  9. Click Save to complete the creation.
