laravel migrate:refreshとmigrate:resetの違い

migrate:refresh と migrate:reset 何が違うんや？
migrationを再実行の場合はrefreshでいいのかな？

[vagrant@localhost test]$ php artisan migrate:refresh
Nothing to rollback.

In Connection.php line 647:

already existってエラーが出てる。resetでやってみると、

[vagrant@localhost test]$ php artisan migrate:reset
Nothing to rollback.                                                                                      

mysql> use test;
Database changed
mysql> show tables;
+—————-+
| Tables_in_test |
+—————-+
| migrations |
| users |
+—————-+
2 rows in set (0.00 sec)

あれ、うまくいってない？？
mysql> drop table migrations;
Query OK, 0 rows affected (0.01 sec)

mysql> drop table users;
Query OK, 0 rows affected (0.00 sec)

[vagrant@localhost test]$ php artisan migrate
Migration table created successfully.

いまいち理解できてないです。

公式では、、
migrate:refresh Reset and re-run all migrations
migrate:reset Rollback all database migrations
resethはrollbackで、refreshはre-runですな。
