mysql - 插件 'FEDERATED' 已禁用

Question

我正在尝试使用 easyPHP 启动 MySQL:响应是日志文件的警报窗口。主要错误是<-- Plugin 'FEDERATED' is disabled -->。

通过在线研究，我发现解决方案是将联合选项添加到 my.ini 文件中。我这样做了，但仍然无法正常工作。

以下是日志文件的摘录以获取更多信息:

Answer 1

关于 FEDERATED disabled 的消息不是错误。这只是意味着 FEDERATED 引擎对于您的 mysql 服务器没有开启。默认情况下不使用它。如果您不需要它，请不要关心此消息。

The FEDERATED storage engine is available beginning with MySQL 5.0.3. It is a storage engine that accesses data in tables of remote databases rather than in local tables.
