Ruby on rails SSHKit:：Runner:：ExecuteError:执行时发生异常

我在尝试通过gem Capistrano将我的应用程序部署到主机时遇到问题

我有下一个错误列表：

   (Backtrace restricted to imported tasks)
    cap aborted!
    SSHKit::Runner::ExecuteError: Exception while executing as hosting_yurta24@calcium.locum.ru: rake exit status: 1

我的deploy.rb文件是：

lock '3.4.0'

    application = 'yurta24'
    login = 'yurta24'
    $user = 'hosting_' + login
    $server = 'calcium.locum.ru'
    rvm_ruby_string = '2.1.5p273'
    deploy_to = "/home/#{ $user }/projects/#{ application }"
    unicorn_conf = "/etc/unicorn/#{ application }.#{ login }.rb"
    unicorn_pid = "/var/run/unicorn/#{ $user }/#{ application }.#{ login }.pid"
    unicorn_start_cmd = "(cd #{ deploy_to }/current; rvm use #{ rvm_ruby_string } do bundle exec unicorn_rails -Dc #{ unicorn_conf })"

    set :application, application 
    set :repo_url, "https://github.com/verrom/yurta24.git"
    set :deploy_to, deploy_to
    set :pty, true
    set :default_env, { path: "xxxxx" }
    namespace :deploy do

      after :restart, :clear_cache do
        on roles(:web), in: :groups, limit: 3, wait: 10 do
        end
      end

connect_to = "#{$user}@#{$server}"
role :app, [connect_to]
role :web, [connect_to]
role :db,  [connect_to]
set :enable_ssl, true

我的production.rb文件是：

    application = 'yurta24'
    login = 'yurta24'
    $user = 'hosting_' + login
    $server = 'calcium.locum.ru'

    deploy_to = "/home/#{ $user }/projects/#{ application }"

      after :restart, :clear_cache do

        end
      end

connect_to = "#{$user}@#{$server}"
role :app, [connect_to]
role :web, [connect_to]
role :db,  [connect_to]
set :enable_ssl, true

更新数据库后完整更新的错误报告。yml为：

谢谢

所以capistrano报告说您在database.yml产品中缺少数据库适配器。您似乎错误地将postgresql作为数据库名而不是适配器名

在database.yml中，您应该具有以下内容：

development:
  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000

test:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000

production:
  adapter: postgresql
  database: you_app_name_production
  username: yourdatabaseusername #in most cases this will be postgres
  password: youdatabasepassword
  pool: 5
  timeout: 5000

在Gemfile中，确保开发和测试gourp中有sqlite gem，生产中有postgres gem（pg），如下所示：

group :development, :test do
  # all your other dev and test gems
  gem 'sqlite3'
end

# outsite your developement and test group add this
gem 'pg'

现在！运行

bundle安装

然后

cap production deploy:检查

是否一切顺利。您可能需要为远程服务器postgres配置用户名和密码

如果您还面临进一步的问题，您可以按照完整的指南来将Rails 4应用程序（Nginx+Capistrano+Unicorn）部署到您的Ubuntu VPS

希望这有帮助。

我们能看到完整的错误报告吗？什么时候失败？它在失败之前是否经过了特定的capistrano配方？请尝试$cap production deploy:check，是否报告了相同的错误？@moeabdo，您好。我已经更新了我的问题。是的，它在失败之前要经过一个特殊的capistrano配方。是的，我想，错误是一样的。你能给你看一下数据库吗。yml“ActiveRecord:：AdapterNotSpecified:数据库配置没有指定适配器”@moeabdol，我更新了一个问题。那不行。。我已经更新了我的问题。在database.yml中，我已将you_app_name_production更改为DB name，hoster给了我什么，对吗？应该是yurta24_production我已将you_app_name_production更改为yurta24_production，错误相同。抱歉，错误是另一个。我在问题中更新了日志。您似乎有权限问题！你试过按照我在答案中链接的教程吗？
