--------------------------------------------------------------------------------
 1 | ### 作用是把你现有的数据库表结构和数据选择性导出生成yii2的迁移文件
 2 | 
 3 | 1.下载模块源码解压缩到 `backend/modules/`
 4 | 
 5 | 2.在 `backend/config/main.php` 添加如下配置
 6 | 
 7 | ```
 8 | 'modules' => [
 9 |         'migration' => [
10 |             'class' => 'migration\Module',
11 |         ]
12 |     ],
13 | 'aliases' => [
14 |         '@migration' => '@backend/modules/migration',
15 |     ],
16 | ```
17 | 
18 | 3.在你的后台访问 http://yourdomain/migration
19 | 
20 | 演示地址： http://www.51siyuan.cn/admin/migration
21 | 
22 | 演示账号 `demo`  密码 `111111`
23 | 
24 | 
25 | 
26 | 命令行使用方法
27 | 
28 | 1.在`console/config/main.php` 添加如下配置
29 | ```
30 | 'controllerMap' => [
31 |         'migrate' => [
32 |             'class' => 'backend\modules\migration\console\MigrateController',
33 |             'useTablePrefix' => true,
34 |             'migrationPath' => '@console/migrations',
35 |         ],
36 |     ],
37 | ```
38 | 
39 | 2.`php yii migrate/dump`
40 | 
41 | o了
