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。)

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!

下面是一个为Django用户提供的方法:

from django.core.management.base import BaseCommand
from django.db import connections


class Command(BaseCommand):

    def handle(self, database="default", *args, **options):

        cursor = connections[database].cursor()

        cursor.execute("SHOW TABLE STATUS");

        for row in cursor.fetchall():
            if row[1] != "InnoDB":
                print "Converting %s" % row[0],
                result = cursor.execute("ALTER TABLE %s ENGINE=INNODB" % row[0])
                print result

将它添加到你的应用程序的文件夹管理/命令/下，然后你可以用manage.py命令转换所有的表:

python manage.py convert_to_innodb

这是一个简单的php脚本。

<?php
    @error_reporting(E_ALL | E_STRICT);
    @ini_set('display_errors', '1');


    $con = mysql_connect('server', 'user', 'pass');
    $dbName = 'moodle2014';

    $sql = "SELECT table_name FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = '".$dbName."';";
    $rs = mysql_query($sql, $con);

    $count = 0;
    $ok = 0;
    while($row = mysql_fetch_array($rs)){
            $count ++;
            $tbl = $row[0];
            $sql = "ALTER TABLE ".$dbName.".".$tbl." ENGINE=INNODB;";
            $resultado = mysql_query($sql);
            if ($resultado){
                    $ok ++;
                    echo $sql."<hr/>";
            }
    }
    if ($count == $ok){
            echo '<div style="color: green"><b>ALL OK</b></div>';
    }else{
            echo '<div style="color: red"><b>ERRORS</b>Total tables: '.$count.', updated tables:'.$ok.'</div>';
    }

<?php
    // connect your database here first 
    // 

    // Actual code starts here 

    $sql = "SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
        WHERE TABLE_SCHEMA = 'your_database_name' 
        AND ENGINE = 'MyISAM'";

    $rs = mysql_query($sql);

    while($row = mysql_fetch_array($rs))
    {
        $tbl = $row[0];
        $sql = "ALTER TABLE `$tbl` ENGINE=INNODB";
        mysql_query($sql);
    }
?>

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
