我試圖在我的Ubuntu服務器上的一個新的rails項目上執行以下命令。Ruby On Rails Mysql訪問被拒絕
rails g scaffold User email:string username:string
但是我收到以下錯誤：

我試圖訪問mysql的經過我在database.yml中提供，我可以登錄就好了證書服務器。但出於某種原因，我無法通過Ruby on Rails命令執行此操作。我的database.yml的是：
# MySQL. Versions 4.1 and 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
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: membershipServices_development
pool: 5
username: root
password: ******
socket: /var/run/mysqld/mysqld.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:
adapter: mysql2
encoding: utf8
reconnect: false
database: membershipServices_test
pool: 5
username: root
password: ******
socket: /var/run/mysqld/mysqld.sock
production:
adapter: mysql2
encoding: utf8
reconnect: false
database: membershipServices_production
pool: 5
username: root
password: ******
host: localhost
socket: /var/run/mysqld/mysqld.sock
我再次驗證了用戶名和密碼提供正確的是通過終端通過我的服務器上登錄到MySQL。感謝您的幫助！
