1、根据官网文档的说明，你的错误信息显示用的是 O_DSYNC ，但你说你的是 WIN7，那明显是用错了呗
2、Permitted Values (Unix) Type string NULL O_DSYNC littlesync nosync O_DIRECT O_DIRECT_NO_FSYNC
3、Permitted Values (Windows) Type string NULL normal unbuffered
4、Win10 下测试这两个都没问题，NULL 就是不指定，试了下无法在配置文件中指定 NULLinnodb_flush_method=normalinnodb_flush_method=unbuffered
