它还没有被提及，所以我将为后人写下来:

如果你在DB服务器之间迁移(或者有其他原因你需要转储和重新加载你的dta)，你可以修改mysqldump的输出:

mysqldump --no-data DBNAME | sed 's/ENGINE=MyISAM/ENGINE=InnoDB/' > my_schema.sql;
mysqldump --no-create-info DBNAME > my_data.sql;

然后再次加载:

mysql DBNAME < my_schema.sql && mysql DBNAME < my_data.sql

(此外，根据我有限的经验，这可能是一个比“实时”修改表快得多的过程。这可能取决于数据和索引的类型。)

当表很大时，最好从控制台进行操作

convert-to-innodb.sh

#!/usr/bin/env bash

# Usage: ./convert-to-innodb.sh 'db' 'user' 'password' | mysql 'db' -u  user -p password


set -eu

db="$1"
user="$2"
pass="$3"


sql="SET @DATABASE_NAME = '${db}';"

sql+="SELECT  CONCAT('ALTER TABLE \`', table_name, '\` ENGINE=InnoDB;') AS sql_statements
FROM    information_schema.tables AS tb
WHERE   table_schema = @DATABASE_NAME
AND     \`ENGINE\` = 'MyISAM'
AND     \`TABLE_TYPE\` = 'BASE TABLE'
ORDER BY table_name DESC;"

echo $sql | mysql -u${user} -p${pass} | tail -n +2 

在mysql中，你可以使用文本编辑器进行搜索/替换:

SELECT table_schema, table_name FROM INFORMATION_SCHEMA.TABLES WHERE engine = 'myisam';

注意:你可能应该忽略information_schema和mysql，因为“mysql和information_schema数据库，实现了一些mysql内部，仍然使用MyISAM。特别是，你不能切换授权表来使用InnoDB。”(http://dev.mysql.com/doc/refman/5.5/en/innodb-default-se.html)

在任何情况下，请注意要忽略并运行的表:

SELECT table_name FROM INFORMATION_SCHEMA.TABLES WHERE engine = 'myisam';

现在只需复制/粘贴列表到你的文本编辑器，搜索/替换“|”与“ALTER TABLE”等。

然后你会有一个这样的列表，你可以简单地粘贴到你的mysql终端:

ALTER TABLE arth_commentmeta           ENGINE=Innodb;
ALTER TABLE arth_comments              ENGINE=Innodb;
ALTER TABLE arth_links                 ENGINE=Innodb;
ALTER TABLE arth_options               ENGINE=Innodb;
ALTER TABLE arth_postmeta              ENGINE=Innodb;
ALTER TABLE arth_posts                 ENGINE=Innodb;
ALTER TABLE arth_term_relationships    ENGINE=Innodb;
ALTER TABLE arth_term_taxonomy         ENGINE=Innodb;
ALTER TABLE arth_terms                 ENGINE=Innodb;
ALTER TABLE arth_usermeta              ENGINE=Innodb;

如果你的文本编辑器不能很容易地做到这一点，这里有另一个解决方案，为一个类似的列表(你可以粘贴到mysql)，你的数据库只有一个前缀，从linux终端:

mysql -u [username] -p[password] -B -N -e 'show tables like "arth_%"' [database name] | xargs -I '{}' echo "ALTER TABLE {} ENGINE=INNODB;"

一个简单的MySQL版本。

你可以简单地启动mysql可执行文件，使用数据库和复制粘贴查询。

这将把当前数据库中的所有MyISAM表转换为INNODB表。
