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: MyISAM Support: DEFAULT Comment: MyISAM storage engine Transactions: NO XA: NO Savepoints: NO *************************** 2. row *************************** Engine: CSV Support: YES Comment: CSV storage engine Transactions: NO XA: NO Savepoints: NO *************************** 3. row *************************** Engine: MEMORY Support: YES Comment: Hash based, stored in memory, useful for temporary tables Transactions: 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 tables Transactions: NO XA: NO Savepoints: NO *************************** 6. row *************************** Engine: PERFORMANCE_SCHEMA Support: YES Comment: Performance Schema Transactions: NO XA: NO Savepoints: NO *************************** 7. row *************************** Engine: ARCHIVE Support: YES Comment: Archive storage engine Transactions: NO XA: NO Savepoints: NO *************************** 8. row *************************** Engine: FEDERATED Support: NO Comment: Federated MySQL storage engine Transactions: NULL XA: NULL Savepoints: NULL *************************** 9. row *************************** Engine: InnoDB Support: NO Comment: Supports transactions, row-level locking, and foreign keys Transactions: NULL XA: NULL Savepoints: NULL rows 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。
