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 .databasemigrations20161117144043_users.php
使用实例
<?php
use PhinxMigrationAbstractMigration;
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()
{
}
}
对于同一个数据表，如果需要新的迁移动作，例如删除字段、创建字段，可以创建新的更改文件，像svn一样往前记录操作，方便回滚。
