为什么我无法使用 MySQL Workbench 连接到我的 MySQL 数据库？

Question

我无法使用 MySQL Workbench 连接到我的 MySQL 数据库。我正在使用 MySQL Community Server 8.0.11 和 MySQL Workbench 6.3 CE。我也在使用 Windows 10 家庭版。

当我在 MySQL Workbench 中单击默认 MySQL 连接时，它说它遇到了错误。没有提供更多信息。

我可以使用该命令毫无问题地连接到我的 MySQL 服务器 mysql -u root -p -h 127.0.0.1 -P 3306.

以下是我的服务器的状态。

我使用 -log-level=debug3 命令执行了 MySQL Workbench：MySQLWorkbench.exe -log-level=debug3。

阅读程序生成的日志后发现如下信息：

21:10:22 [ERR][  GRTDispatcher]: exception in grt execute_task, continuing: Exception: Authentication plugin 'caching_sha2_password' cannot be loaded: Não foi possível encontrar o módulo especificado.

这个问题Authentication plugin 'caching_sha2_password' cannot be loaded 帮助我解决了这个问题。现在我可以连接到我的 MySQL 服务器了。

看起来是 MySQL Workbench 在您的机器上没有正确启动。我从官方网站上找到this 尝试看看它是否有效，如果没有尝试将错误报告给开发团队并等待回复。或者，您可以尝试使用其他工具连接到您的数据库。
