mysql修改datadir的后续工作
我们都知道，在mysql文件夹下面有my.ini文件，修改里面的datadir就可以改变数据库以及表的存放位置，默认在windows下，存放在C:/ProgramData/MySQL/MySQL Server 5.5/Data/，比如我们将datadir修改为I:/data，可能会遇到以下几种情况：
1、重新打开mysql administrator或者相应的command line，我们发现数据的存储位置依然是原来的目录，出现这样的原因是没有停止mysql服务，my.ini没有在启动时重新被读取，我们可以通过命令行停止，或者在控制面板——管理——服务里面停止mysql服务，然后再开启；
2、重新开启mysql服务时，出现了1067的错误，此时我们可以查看datadir所在的新目录下的错误日志文件，可能的原因是，没有将datadir原目录下的performance_schema和mysql两个文件夹复制到新目录下！ 将它们复制过来即可。
