遵循步骤:

Use MySql commands as follows, for converting to InnoDB (ALTER TABLE t1 ENGINE = InnoDB) or (ALTER TABLE t1 ENGINE = MyISAM) for MyISAM (You should do this for each individual tables, t1 is for the table name.). Write a script that loops on all tables and run the alter command Use an already available script to handle that: https://github.com/rafihaidari/convert-mysql-tables-storage-engine Try this SQL to Get all info will get all the tables information then you can change all the table from isam to InnoDB SELECT CONCAT('ALTER TABLE ',TABLE_NAME,' ENGINE=InnoDB;') FROM INFORMATION_SCHEMA.TABLES WHERE ENGINE='MyISAM' AND table_schema = 'your_DB_Name';

你可以在mysql命令行工具中执行这个语句:

echo "SELECT concat('ALTER TABLE `',TABLE_NAME,'` ENGINE=InnoDB;')
FROM Information_schema.TABLES 
WHERE ENGINE != 'InnoDB' AND TABLE_TYPE='BASE TABLE' 
AND TABLE_SCHEMA='name-of-database'" | mysql > convert.sql

您可能需要指定用户名和密码:mysql -u username -p 结果是一个sql脚本，你可以管道回mysql:

mysql name-of-database < convert.sql

替换上述语句和命令行中的"name-of-database"。

SELECT CONCAT('ALTER TABLE ',TABLE_NAME,' ENGINE=InnoDB;') 
FROM INFORMATION_SCHEMA.TABLES
WHERE ENGINE='MyISAM'
AND table_schema = 'mydatabase';

效果非常好。

这将为您提供可以批处理运行的带有alter查询的所有表的列表

在phpMyAdmin中使用此sql查询

SELECT CONCAT('ALTER TABLE ',table_schema,'.',table_name,' engine=InnoDB;') 
FROM information_schema.tables 
WHERE engine = 'MyISAM';

对于转换MySql表存储引擎有许多方法:

使用MySql命令如下，转换为innodb (ALTER TABLE t1 ENGINE = innodb)或(ALTER TABLE t1 ENGINE = MyISAM)为MyISAM(你应该为每个单独的表这样做，t1是表名。) 编写一个在所有表上循环的脚本，并运行alter命令 使用一个已经可用的脚本来处理这个问题:https://github.com/rafihaidari/convert-mysql-tables-storage-engine

还有另一种选择……下面是如何在ansible中做到这一点。它假设数据库的名称在dbname中，并且您已经配置了访问权限。

- name: Get list of DB tables that need converting to InnoDB
  command: >
    mysql --batch --skip-column-names --execute="SELECT TABLE_NAME
    FROM information_schema.TABLES
    WHERE TABLE_SCHEMA = '{{ dbname }}' AND ENGINE = 'MyISAM';"
  register: converttables
  check_mode: no
  changed_when: False

- name: Convert any unconverted tables
  command: >
    mysql --batch --skip-column-names --execute="ALTER TABLE `{{ dbname }}`.`{{ item }}` ENGINE = InnoDB;"
  with_items: "{{ converttables.stdout_lines }}"
