這兩天新買的服務器mysql總是自動停止，查了日志

  9:13:57 [Note] MySQL: Normal shutdown
  9:13:57 [Note] Event Scheduler: Purging the queue. 0 events
  9:13:57  InnoDB: Starting shutdown...
  9:13:58  InnoDB: Shutdown completed; log sequence number 0 44273
  9:13:58 [Note] MySQL: Shutdown complete

重啟發現

  9:14:24 [Note] MySQL: Normal shutdown

網上找到的方法

在MY.INI文件中的 [mysqld] 中增加一行tmpdir="D:/MySQL/data/tmp"
刪除MySQL目錄下的ib_logfile0和ib_logfile1

測試后沒有用

后來在服務中設置了mysql自動重啟

最后
[mysqld]
federated

解決
啟動正常
