从ubuntu平台的rails应用程序连接远程mysql2

Question

我使用两台ubuntu机器，一台用于mysql2 server，另一台用于轨道用于mysql2 client，我需要从另一台机器上的rails应用程序连接mysql2 server。我使用的配置中database.yml：

default: &default 

    adapter: mysql2 

    encoding: utf8 

    pool: 5 

    username: root 

    password: dani123* 

    host: 192.168.1.185 

    port: 3306 

    socket: /var/run/mysqld/mysqld.sock 

但同时我运行rake db:create系统引发以下error。请帮助我

Couldn't create database for {"adapter"=>"mysql2", "encoding"=>"utf8", "pool"=>5, "username"=>"root", "password"=>"dani123*", "host"=>"192.168.1.185", "port"=>3306, "socket"=>"/var/run/mysqld/mysqld.sock", "database"=>"remotedb_development"}, {:charset=>"utf8", :collation=>"utf8_unicode_ci"} 
(If you set the charset manually, make sure you have a matching collation)

您的database.yml似乎缺少database属性。当你在那里指定数据库时，试着用hostname:port/db
