“rails 服务器”的问题

Question

我是 Ruby on Rails 的新手，很抱歉这个问题，这可能很简单，但是..

所以，这是我的问题：我有带有 RoR 的 Ubuntu 12.04。我正在参与一些项目，所以我检查了 svn，安装了 bundle，现在我遇到了 rails 服务器的问题。这是来自终端的日志

连接 MySQL 数据库时出错：

/usr/lib/ruby/gems/1.8/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:in `connect': 拒绝用户 'fubademoall'@'localhost' 访问（使用密码：YES) (Mysql2::Error)

检查 config/database.yml 中的配置是否与您正在使用的 MySQL 服务器上的数据库凭据匹配。

Answer 2

If you are new Please see following eg: for creating database, grant ,and database.yml file  

=> Go to Mysql :
D:\sandeep\Ruby Projects\simple_cms>mysql -u root -p
Enter password: ********

=>Create Database :
 create database simple_cms_development 

=>Gtanting the Access to database : 
 mysql> grant all privileges on simple_cms_development.*
     ->to 'simple_cms' @'localhost'
     -> identified by 'secretpassword';
Query OK, 0 rows affected (0.00 sec)

=>See Database and Grant :
 mysql> show grants for 'simple_cms' @'localhost';

=>And Your database.yml file like this :
development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: simple_cms_development
  pool: 5
  username: simple_cms
  password: secretpassword
  socket: /tmp/mysql.sock

test:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: simple_cms_test
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: simple_cms_production
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

Answer 3

我认为错误信息的相关行是：

`connect': Access denied for user 'fubademoall'@'localhost' (using password: YES) (Mysql2::Error)

你设置mysql了吗？权限是否正确？
