只是测试了另一种(简单的?)方法，对我来说很有效。

只需导出您的DB为.sql文件，编辑它与gedit或记事本;

将ENGINE=MyISAM替换为ENGINE=INNODB并保存已编辑的文件

编号或替换完成应该是你的表的编号

导入到MySQL (phpMyAdmin或命令行)

瞧!

对这个util脚本的一些修复

SET @DATABASE_NAME = 'Integradb';

SELECT  CONCAT('ALTER TABLE ', table_schema, '.', 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;

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"。

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 }}"

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 

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';
