我正在尝试运行 cap deploy:cold 以使用 postgresql 安装 rails 应用程序，但我无法弄清楚“未配置生产数据库”或其他任何内容是什么意思。

错误消息意味着您没有在 database.yml 中配置生产数据库。

看看你database.yml在远程服务器上的情况。

它应该类似于：

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

我建议执行以下操作：

1.) 不要将您的存储database.yml在版本控制之下。使用 git 时，只需添加/config/database.yml到.gitignore文件中（或创建该文件）并提交即可。

2.)database.yml在远程服务器上创建shared/config/（通过脚本，或手动）。

3.）将database.yml您的应用程序中的符号链接到shared/config部署中。

# /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
