MySQL 数据库跨操作系统的最快迁移方法
原始的是Windows 2003下的32位的MySQL数据库， 新的服务器是Sun的64位的小型机，64位的MySQL数据库。
数据库文件很大，约有70G,如果普通的迁移，需要在原始数据库导出数据，然后在新数据库导入数据
经仔细考虑，是否MySQL的数据库文件存储格式在不同的操作系统相同呢？
测试过程如下：
在64位SUN机器上安装64位版的MySQL
停止MySQL服务
复制Windows上的32位MySQL的数据文件(全部，除了system和日志等)到64位机器上，
修改相应的文件和目录权限，
文件为 chmod 660
目录为 chmod 700
然后重启MySQL服务，运行正常。
总结：
别以为这个看上去很简单，许多人会错误的认为，不同的操作系统，其存储并不是通用的，而这个例子证明，相同数据库数据的存储结构是没有区别的，完全可以直接拿来使用。
附上中间遇到的一个小异常，那就是数据库的数据目录，必须有可执行的权限，也就是7的权限，6的不可以。

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches.
