MySQL数据迁移问题一MySQL的数据迁移比较简单，但有几点一定要注意：
?
当启用InnoDB引擎，在my.ini中有一个配置项：innodb_log_file_size
必须保证移植前后这个配置值是相同的，不然服务无法启动
如果不知道这个值咋办呢，查看日志
?
InnoDB: Error: log file .\ib_logfile0 is of different size 0 359661568 bytes InnoDB: than specified in the .cnf file 0 56623104 bytes! 140525 17:21:20 [ERROR] Plugin 'InnoDB' init function returned error. 140525 17:21:20 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 140525 17:21:20 [ERROR] Unknown/unsupported table type: INNODB 140525 17:21:20 [ERROR] Aborting
我们看看到，日志很清楚的显示了原来的innodb_log_file_size和现在的innodb_log_file_size，把现在的配置改为原来的即可。
