批量修改Mysql表引擎为InnoDB

注意：本文最后更新于 2527 天前，有关的内容可能已经发生变化，请参考使用。

一般批量修改MYSQL中某表的数据库引擎可以利用官方工具mysql_convert_table_format来实现，这里指的是不使用其他工具仅用shell的方法来实现。（以下例子效果是将数据库ecjtubbs中所有引擎不为InnoDB的表修改为使用InnoDB引擎）

先用shell获取需要更换表引擎：

    mysql --user=root --password=passwd -e "show table status from ecjtubbs where Engine <> 'InnoDB'G"|grep Name|awk '{print "alter table "$2" engine=innodb;";}' >mysqlchange

这样在mysqlchange文件里面就会有如下的内容（包含了所有ecjtubbs表中所有引擎不为InnoDB的表名）：

    alter table cdb_activities engine=innodb;
    alter table cdb_activityapplies engine=innodb;

    …………

接下来复制上面的内容，用Putty登录服务器，用“mysql --user=root --password=passwd”登录Mysql在 mysql> 界面后直接点击鼠标右键粘贴即可完成数据表的引擎更换（如果数据库非常大可能要等一段时间）。

其实完全可以通过以下shell完成同样功能的操作：

mysql --user=root --password=passwd -e "show table status from ecjtubbs where Engine <> 'InnoDB'G"|grep Name|awk '{print "mysql --user=root --password=passwd -p ecjtubbs "alter table "$2" engine=innodb;"";}'|bash

只是有的环境下mysql --user=root --password=passwd -p ecjtubbs 并不一定会按照预期的想法登录mysql并选择ecjtubbs数据库，只要你能确保mysql --user=root --password=passwd -p ecjtubbs 能够登录到Mysql并选择ecjtubbs数据库就可以使用一行命令实现修改表引擎的效果。(passwd是root用户的密码)
