发现问题

今天在工作中，从本地数据库复制表数据到虚拟机 CentOS 6.6 上的数据库时，得到提示：

Unknown table engine 'InnoDB'

于是在服务器 MySQL 中查看了引擎：

mysql> show engines\G

得到：

*************************** 1. row ***************************Engine: MyISAMSupport: DEFAULTComment: MyISAM storage engineTransactions: NO XA: NO Savepoints: NO*************************** 2. row ***************************Engine: CSVSupport: YESComment: CSV storage engineTransactions: NO XA: NO Savepoints: NO*************************** 3. row ***************************Engine: MEMORYSupport: YESComment: Hash based, stored in memory, useful for temporary tablesTransactions: NO XA: NO Savepoints: NO*************************** 4. row ***************************Engine: BLACKHOLESupport: YESComment: /dev/null storage engine (anything you write to it disappears)Transactions: NO XA: NO Savepoints: NO*************************** 5. row ***************************Engine: MRG_MYISAMSupport: YESComment: Collection of identical MyISAM tablesTransactions: NO XA: NO Savepoints: NO*************************** 6. row ***************************Engine: PERFORMANCE_SCHEMASupport: YESComment: Performance SchemaTransactions: NO XA: NO Savepoints: NO*************************** 7. row ***************************Engine: ARCHIVESupport: YESComment: Archive storage engineTransactions: NO XA: NO Savepoints: NO*************************** 8. row ***************************Engine: FEDERATEDSupport: NOComment: Federated MySQL storage engineTransactions: NULL XA: NULL Savepoints: NULL*************************** 9. row ***************************Engine: InnoDBSupport: NOComment: Supports transactions, row-level locking, and foreign keysTransactions: NULL XA: NULL Savepoints: NULLrows in set (0.00 sec)

在 InnoDB 的 Supports 为 NO

解决方法

编辑 my.cnf

[root@localhost mysql]# vim /etc/my.cnf

把其中 innodb = OFF 改为 innodb = ON

同时把 skip-innodb 注释掉即可。
