在database.yml中更正用户名和密码，但不接受密码

标签： mysql ruby ruby-on-rails-3 osx-lion

在OS X Lion上，我无法找到为什么它不接受我的密码。我可以连接到数据库并从mysql工作台管理它，但rails似乎无法连接。

从mysql站点下载的dmg安装了Mysql。

我尝试过从mysql命令行授予权限：

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost'

这是来自rake db:create的跟踪我还尝试了bundle exec rake db:create 

Access denied for user 'root'@'localhost' (using password: YES)

编辑：当我跑步时：mysql -u root -p我明白了：

Adamars-MacBook-Pro:~ adamar$ mysql -u root -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

这就是我的database.yml 

test:
  adapter: mysql2
  encoding: utf8
  database: linkdeck_test
  username: root
  password: 
  pool: 5
  host: 127.0.0.1
  port: 3306

development:
  adapter: mysql2
  encoding: utf8
  database: linkdeck_development
  username: root
  password: 
  pool: 5
  host: 127.0.0.1
  port: 3306

production:
  adapter: mysql
  encoding: utf8
  database: linkdeck_production
  username: root
  password: 
  host: 127.0.0.1
  port: 3306

答案 0 :(得分：2)

这看起来很痛苦，但你确定它是对的吗？您说您正在使用工作台GUI，这与从Rails连接它并不相同，因此无法证明您的配置是正确的。

仔细检查以下内容。首先，请确保您的config/database.yml包含以下内容：

development:
  adapter: mysql2
  database: example_development
  username: root
  password: admin12345

如果是，可以运行mysql -u root -p并提供与config/database.yml中密码相同的密码吗？如果没有，那么你的权限就出了问题。

另外，请确保在安装mysql时，通过通常的brew install mysql或其他类似的包管理方法执行此操作。

更新：您无法看到数据库，这极有说明您有权限问题。确保您已创建用户并允许其访问所有数据库。
