Mysql2:：错误：拒绝用户访问'；测试'@'；本地主机'；到数据库'；车辆段测试和x27；

我在这里有点不知所措。我已经创建了一个数据库，使用depot_生产数据库没有问题。然而，最近每当我运行rake测试时，都会出现一系列错误，比如

# Running tests:

EEEEEEEE

Finished tests in 0.031499s, 253.9763 tests/s, 0.0000 assertions/s.

1) Error:
test_should_create_product(ProductsControllerTest):
Mysql2::Error: Access denied for user 'test'@'localhost' to database 'depot_test'

奇怪的是，我认为我的database.yml文件很好。每次运行db:migrate时，我都会收到一条空行。我还添加了一个用户测试，但我认为这只是将其添加到我的开发数据库中。我觉得我的测试、生产和数据库都不存在

development:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_development
pool: 5
username: root
password: admin
socket: /tmp/mysql.sock

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_test
pool: 5
username: test
password: testy
socket: /tmp/mysql.sock

production:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_production
pool: 5
username: prod
password: mypassword
socket: /tmp/mysql.sock

如有任何建议，将不胜感激，谢谢

谢谢你和我在一起。我觉得我很接近，但有些奇怪。这就是我所做的

所以，首先以root身份登录，或者从终端调用您的root用户

mysql -u root -p

CREATE DATABASE depot_test

CREATE USER 'test'@'localhost' IDENTIFIED BY 'mypass123';

USE depot_test

登录mysql后，向用户授予特权

test

（记住更改密码）

---

您需要将数据库中的密码更改为“mypass123”。yml

您需要授予用户“测试”更改“depot_测试”的权限，谢谢！我试了一下，得到了以下结果。错误1046（3D000）：未选择数据库。是。您必须选择

depot\u测试数据库，请参阅编辑。抱歉，消息太长。我已经编辑了我原来的帖子并添加了它。谢谢似乎您没有名为
depot\u test
的数据库，但您有一个名为
test
的数据库，因此我们将创建
depot\u test
好听！Rails的安装总是一件痛苦的事情，幸运的是，您只有mysql问题：）
GRANT ALL privileges on depot_test.* to test@localhost identified by 'mypass123';
