Webrick Rails Server無法正常運行

Question

我花了最后6個小時來解決一些問題，例如修改$ PATH，安裝Gems以便最終獲得應有的一切。 但是在我創建包含項目組件的項目文件夾並嘗試運行服務器后，我收到了以下消息：-

\KAMAL$ ls
Gemfile     README.rdoc app     config.ru   doc     log     script      tmp
Gemfile.lock    Rakefile    config      db      lib     public      test        vendor
\KAMAL$ rails server
=> Booting WEBrick
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting
/Library/Ruby/Gems/1.8/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:in `connect': Access denied for user 'root'@'localhost' (using password: NO) (Mysql2::Error)
    from /Library/Ruby/Gems/1.8/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:in `initialize'
    from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.13/lib/active_record/connection_adapters/mysql2_adapter.rb:16:in `new'

和上面的許多行一樣

此日志條目

Access denied for user 'root'@'localhost' (using password: NO) (Mysql2::Error)

顯示您正在使用本地用戶root在localhost而不使用密碼作為數據庫。 MySQL找不到有效用戶。 以下行應發出相同的錯誤消息：

mysql -u root -h localhost

因此，請檢查db/database.yml文件中的數據庫用戶/密碼
