我正在使用Squirrel连接到托管在 CloudBees 上的 MySQL 实例。我下载了我认为正确的JDBC 驱动程序，并将其安装到 Squirrel 的lib目录中：

~/squirrel-sql-3.4.0/lib/mysql-connector-java-5.1.25-bin.jar

然后，我创建了一个具有以下属性的新数据库别名（在 Squirrel 内部）：

Name: my_db
Driver: MySQL Driver
URL: jdbc:mysql://my-cloudbees-s3-instance.com:3306/my_db
User Name: my_db_user
Password: *******

当我尝试连接到数据库时，我从 Squirrel 的内置控制台收到以下堆栈跟踪/错误：

这是一个问题：

  • 松鼠，或者我如何配置它；或者
  • 数据库/服务器（未正确配置等）；或者
  • 我的连接属性；或者
  • MySQL/JDBC 驱动程序（错误类型等）；或者
  • 还有什么？

它说“访问被拒绝”，但我检查并重新检查了我的登录凭据，它们似乎完全有效。提前致谢！

重要更新：我刚刚下载并安装了 MySQL Workbench，使用完全相同的信息创建了一个新的存储连接，但仍然收到相同的错误消息：

无法使用用户 my_db_user 在 my-cloudbees-s3-instance.com:3306 连接到 MySQL。用户 'my_db_user'@'%' 拒绝访问数据库 'my_db'。

对我来说，这表明 MySQL 服务器配置不正确，排除了 Squirrel、我的连接属性和我为 Squirrel 安装的 JDBC 驱动程序......是吗？！？
