Mysql ruby on rails第一个应用程序访问被拒绝

我正在尝试Ruby，我以前用Java开发过。经过一些努力，我使用MySql2创建了一个使用bitnami rubystack的应用程序。我遇到了一些关于连接器的错误，但我解除了它的stackoverflow。当然，现在我遇到了一个错误，并尝试了stackoverflow解决方案，但它不起作用，所以我在这里问，我尝试了从主机切换到插座，然后再切换回来。每次更改database.yml后，我都会重新启动rails服务器。我需要这样做吗

我正在获取MYSQL2:：Error 用户“rubystack”@“localhost”使用密码的访问被拒绝：是

my database.yml如下所示：

# MySQL.  Versions 5.0+ are recommended.
#
# Install the MYSQL driver
#   gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
#   gem 'mysql2'
#
# And be sure to use new-style password hashing:
#   http://dev.mysql.com/doc/refman/5.0/en/old-client.html
#
default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: root
  password: bitnami123
  host: localhost

development:
  <<: *default
  database: myapp2_dev
  username: rubystack
  password: bitnami1
  #password: <%= ENV['MYAPP2_DATABASE_PASSWORD'] %>
  host: localhost
  #socket: C:\Bitnami\rubystack-2.0.0-23\mysql\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:
  <<: *default
  database: myapp2_test
  username: rubystack
  password: bitnami1
  host: localhost
  #socket: C:\Bitnami\rubystack-2.0.0-23\mysql\tmp\mysql.sock

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
#   DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
#   production:
#     url: <%= ENV['DATABASE_URL'] %>
#
production:
  <<: *default
  database: myapp2_production
  username: rubystack
  password: bitnami1
  host: localhost
  #socket: C:\Bitnami\rubystack-2.0.0-23\mysql\tmp\mysql.sock
  #password: <%= ENV['MYAPP2_DATABASE_PASSWORD'] %>

有没有人遇到它并解决了它？？在哪里可以找到Ruby/Bitnami中的日志文件。日志文件夹为空。顺便说一句：我可以使用$Mysql-u rubystack-p myapp2_dev访问Mysql并输入密码。数据库存在，用户存在，用户rubystack有Previlliges

编辑：我从database.yml中删除了rubystack user的所有痕迹，而是将root作为用户，并将password字段更改为root的password，现在它仍然显示： 拒绝使用密码访问用户“root”@“localhost”：是 先谢谢你
