【问题描述】：
我最近在使用 win 7 时遇到了问题，所以我不得不重新安装....而且我也不得不用 mysql 重新安装 web 服务器
之前我有 mysql 5.1 现在我有 5.5。
我已从 C:\ProgramData\MySQL\MySQL Server 5.1\data（我的数据库的复制目录）
我现在已将所有目录复制到 C:\ProgramData\MySQL\MySQL 服务器 5.5\data
检查结果时，我只看到了 myisqm 表，没有 innodb 表！
SHOW ENGINES 给了我这个
FEDERATED NO Federated MySQL storage engine NULL NULL NULL
MRG_MYISAM YES Collection of identical MyISAM tables NO NO NO
MyISAM YES MyISAM storage engine NO NO NO
BLACKHOLE YES /dev/null storage engine (anything you write to it... NO NO NO
CSV YES CSV storage engine NO NO NO
MEMORY YES Hash based, stored in memory, useful for temporary... NO NO NO
ARCHIVE YES Archive storage engine NO NO NO
InnoDB DEFAULT Supports transactions, row-level locking, and fore... YES YES YES
PERFORMANCE_SCHEMA YES Performance Schema NO NO NO
那我该怎么办？我检查了相关文件在目录中...... f.e.
分类广告.frm 分类广告.MYD 分类广告.MYI
好的，我停止了 mysql55 服务，我覆盖了文件： - ibdata1 - ib_logfile0 - ib_logfile1
来自我的备份...但是当我重新启动服务时出现错误：进程意外终止。检查日志时：
