MySQL DB的Rails项目连接错误-root用户的访问被拒绝

Question

使用 mysql db 运行 rails 时出现此错误。基本上它没有授予root用户访问权限。我不知道为什么会这样，并且已经坚持了一段时间。

Mysql2::Error (Access denied for user 'root'@'localhost' (using password: YES)):
Rendered /Users/USER/.rvm/gems/ruby-1.9.2-p290/gems/actionpack- 3.1.0/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.3ms)
Rendered /Users/USER/.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.1.0/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (5.7ms)
Rendered /Users/USER/.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.1.0/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (17.7ms)

我的 Database.yml 文件发布在下面供您参考。我不确定如何检查 MYSQL 自动分配的密码？会不会是我的电脑登录密码？无论如何我如何检查它。我也不能简单地在我的命令行上键入 mysql 我必须输入整个路径才能访问它。我该如何改变它。最重要的是，我想知道如何解决此访问被拒绝问题。谢谢你。在 mac 上使用 mysql 5.5。 x86_64 构建。

Mysql 使用您在安装时设置的那个。有时它是空的。 试试 mysql -u root。如果可行 - 从数据库 yaml 中删除传递字符串。 如果它不为空 - https://*.com/search?q=mysql+reset+password
