MySQL启动时InnoDB引擎被禁用了的解决方法

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/' target='_blank'>mysql 中查看了引擎：

MySQL> show engines\G

得到：

*************************** 1. row ***************************  Engine: MyISAM  Support: DEFAULT  Comment: MyISAM storage engineTransactions: NO   XA: NO Savepoints: NO*************************** 2. row ***************************  Engine: CSV  Support: YES  Comment: CSV storage engineTransactions: NO   XA: NO Savepoints: NO*************************** 3. row ***************************  Engine: MEMORY  Support: YES  Comment: Hash based, stored in memory, useful for temporary tablesTransactions: NO   XA: NO Savepoints: NO*************************** 4. row ***************************  Engine: BLACKHOLE  Support: YES  Comment: /dev/null storage engine (anything you write to it disappears)Transactions: NO   XA: NO Savepoints: NO*************************** 5. row ***************************  Engine: MRG_MYISAM  Support: YES  Comment: Collection of identical MyISAM tablesTransactions: NO   XA: NO Savepoints: NO*************************** 6. row ***************************  Engine: PERFORMANCE_SCHEMA  Support: YES  Comment: Performance SchemaTransactions: NO   XA: NO Savepoints: NO*************************** 7. row ***************************  Engine: ARCHIVE  Support: YES  Comment: Archive storage engineTransactions: NO   XA: NO Savepoints: NO*************************** 8. row ***************************  Engine: FEDERATED  Support: NO  Comment: Federated MySQL storage engineTransactions: NULL   XA: NULL Savepoints: NULL*************************** 9. row ***************************  Engine: InnoDB  Support: NO  Comment: 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。
