错误消息表示您没有在database.yml中配置生产数据库

查看远程服务器上的

数据库.yml

它应该类似于这样：

production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: database_name
  pool: 5
  username: database_user
  password: th3p4ssw0rd
  socket: /path/to/mysql.sock

我建议采取以下措施：

1.）不要在版本控制下存储

数据库.yml

。 使用git时，只需将

/config/database.yml

添加到

.gitignore

文件（或创建该文件）中

# /config/deploy.rb:
after 'deploy:finalize_update', 'db:symlink'

namespace :db do
  desc "Symlinks the database.yml"
  task :symlink, :except => { :no_release => true }, :roles => :app do
    run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
  end
end
