为什么我不能使用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社区服务器8.0.11 和 MySQL Workbench 6.3 CE 。我也在使用Windows 10 Home。

当我点击MySQL Workbench中的默认MySQL连接时，它说它遇到了错误。没有提供更多信息。

我可以使用该命令连接到我的MySQL服务器而没有任何问题 mysql -u root -p -h 127.0.0.1 -P 3306。

以下是我服务器的状态。

看起来 MySQL Workbench 在您的计算机上无法正常启动。我从官方网站上找到了this，试试看是否有效，如果没有尝试向开发团队报告错误并等待回复。或者，您可以尝试使用其他工具连接到数据库。

我使用-log-level = debug3命令执行MySQL Workbench：21:10:22 [ERR][SQL Editor Form]: SqlEditorForm: exception in do_connect method: Exception: Authentication plugin 'caching_sha2_password' cannot be loaded: Não foi possível encontrar o módulo especificado. 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. 21:10:22 [ERR][ GRTDispatcher]: worker: task 'execute sql queries' has failed with error:.Authentication plugin 'caching_sha2_password' cannot be loaded: Não foi possível encontrar o módulo especificado. 21:10:22 [ERR][SQL Editor Form]: SQL editor could not be connected: Authentication plugin 'caching_sha2_password' cannot be loaded: Não foi possível encontrar o módulo especificado. 21:10:22 [ERR][SQL Editor Form]: Your connection attempt failed for user 'root' from your host to server at 127.0.0.1:3306: Authentication plugin 'caching_sha2_password' cannot be loaded: Não foi possível encontrar o módulo especificado. 。

在阅读程序生成的日志后，我发现了以下信息：

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。
