在使用虚拟服务器时，服务器提供商一般不会像我们使用本地数据库一样：使用导入导出（这样的文件后缀是*.sql）。大部分时候提供的是一个文件夹，里面包括：数据库名文件夹，文件夹里包括，*.frm,*.MYI,*.MYD,并且包含一个db.opt文件。分别介绍一下：
    *.frm----描述了表的结构
    *.MYI----表的索引
    *.myd----保存了表的数据记录
    db.opt----用文本编辑器打开，可以看到里面保存的是编码信息

要把上述的数据库导入进mysql：

安装mysql数据库：我安装的数据库是MySQL Server 5.5，安装目录选择:D:/program files/MySQL （注意：路径中不要包含中文）
在C:/Documents and Settings/All Users/Application Data/ 里找到 MySQL/MySQL Server 5.5文件夹，该文件夹下有个文件： my.ini
在my.ini文件里找到一个datadir的key如：datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.5/data/“
在3找到的一个data文件夹下，拷贝服务商提供备份时提供的文件（包括*.frm,*.MYI,*.MYD,db.opt）
一般重启mysql服务，在管理界面就可以看到表的结构及数据了
