服务器环境LNMP Centos6.5 64位，
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  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/”
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
