这两天新买的服务器mysql总是自动停止，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

重启发现

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

网上找到的方法

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

测试后没有用

后来在服务中设置了mysql自动重启

最后
[mysqld]
federated

解决
启动正常

顺手添加
skip-external-locking
skip-name-resolve
解决
