数据库迁移工具

数据库迁移工具

首先通过 Composer 安装

composer require topthink/think-migration

注意事项，不支持修改文件配置目录

在命令行下运行查看帮助，可以看到新增的命令

php think 

 migrate
  migrate:create     Create a new migration
  migrate:rollback   Rollback the last or to a specific migration
  migrate:run        Migrate the database
  migrate:status     Show migration status
 optimize
  optimize:autoload  Optimizes PSR0 and PSR4 packages to be loaded wit
h classmaps too, good for production.
  optimize:config    Build config and common file cache.
  optimize:route     Build route cache.
  optimize:schema    Build database schema cache.
 seed
  seed:create        Create a new database seeder
  seed:run           Run database seeders

创建迁移类，首字母必须为大写

php think migrate:create Users

可以看到目录下有新文件 .\database\migrations\20161117144043_users.php

使用实例

<?php

use Phinx\Migration\AbstractMigration;

class Users extends AbstractMigration
{
    /**
     * Change Method.
     */
    public function change()
    {
        // create the table
        $table = $this->table('users',array('engine'=>'myisam'));
        $table->addColumn('username', 'string',array('limit' => 15,'default'=>'','comment'=>'用户名，登陆使用'))
            ->addColumn('password', 'string',array('limit' => 32,'default'=>md5('123456'),'comment'=>'用户密码'))
            ->addColumn('login_status', 'boolean',array('limit' => 1,'default'=>0,'comment'=>'登陆状态'))
            ->addColumn('login_code', 'string',array('limit' => 32,'default'=>0,'comment'=>'排他性登陆标识'))
            ->addColumn('last_login_ip', 'integer',array('limit' => 11,'default'=>0,'comment'=>'最后登录IP'))
            ->addColumn('last_login_time', 'datetime',array('default'=>0,'comment'=>'最后登录时间'))
            ->addColumn('is_delete', 'boolean',array('limit' => 1,'default'=>0,'comment'=>'删除状态，1已删除'))
            ->addIndex(array('username'), array('unique' => true))
            ->create();
    }

    /**
     * Migrate Up.
     */
    public function up()
    {

    }

    /**
     * Migrate Down.
     */
    public function down()
    {

    }
}
