mysql 5.1默认只启用MyISAM, 使用INNODB要做一下修改:
=== InnoDB Storage Engine ===
Plugin Name: innobase
Description: Transactional Tables using InnoDB
Supports build: static and dynamic
Configurations: max, max-no-ndb
mysql 5.1版本之后,要使用innodb有两种方法
(1).静态编译的时候加入 --with-plugin-innobase (2).动态扩展 启动mysqld后
mysql>INSTALL PLUGIN innodb SONAME 'ha_innodb.so'
mysql> show plugin
就可以看见了
动态的话plugin_dir要指定正确:
[mysqld] plugin_dir=/path/to/plugin/directory
最后,通过动态方式,解决了这个转换问题。
查看mysql 5.1 是否安装了innodb插件(mysql 5.0使用: show variables like 'have_%';)
mysql> show plugins; +------------+--------+----------------+--------------+---------+ | Name | Status | Type | Library | License | +------------+--------+----------------+--------------+---------+ | binlog | ACTIVE | STORAGE ENGINE | NULL | GPL | | CSV | ACTIVE | STORAGE ENGINE | NULL | GPL | | MEMORY | ACTIVE | STORAGE ENGINE | NULL | GPL | | MyISAM | ACTIVE | STORAGE ENGINE | NULL | GPL | | MRG_MYISAM | ACTIVE | STORAGE ENGINE | NULL | GPL | | +------------+--------+----------------+--------------+---------+ 5 rows in set (0.00 sec)
发现没有安装 INNODB,执行下面语句: mysql> install plugin innodb soname 'ha_innodb.so';
再次查看: mysql> show plugins; +------------+--------+----------------+--------------+---------+ | Name | Status | Type | Library | License | +------------+--------+----------------+--------------+---------+ | binlog | ACTIVE | STORAGE ENGINE | NULL | GPL | | CSV | ACTIVE | STORAGE ENGINE | NULL | GPL | | MEMORY | ACTIVE | STORAGE ENGINE | NULL | GPL | | MyISAM | ACTIVE | STORAGE ENGINE | NULL | GPL | | MRG_MYISAM | ACTIVE | STORAGE ENGINE | NULL | GPL | | InnoDB | ACTIVE | STORAGE ENGINE | ha_innodb.so | GPL | +------------+--------+----------------+--------------+---------+ 6 rows in set (0.00 sec)
2. 查看表的类型:
mysql> use web_db; mysql> show tablse;
随便找个表看类型: mysql> show create table sys_user;
查看是否有以下字段: ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8
如何将MyISAM库 导成 INNODB:
在备份出的 xxx.bak文件中 把 ENGINE=MyISAM 全换成 ENGINE=INNODB 再次导入就可以了。
转换表的命令:
alter table POD engine=innodb;
