SSHKit :: Runner :: ExecuteError：执行时出现异常

我尝试通过gem Capistrano将我的应用程序部署到主机时出现问题。SSHKit :: Runner :: ExecuteError：执行时出现异常

我有一个出错列表：

(Backtrace restricted to imported tasks) 
    cap aborted! 
    SSHKit::Runner::ExecuteError: Exception while executing as [email protected]: rake exit status: 1

我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

我production.rb文件是：

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

全部更新错误报告后更新database.yml是：

我们可以看到完整的错误报告吗？这何时失败？在它失败之前它是否通过特定的卡皮斯特拉诺配方？ – moeabdol

也尝试$ cap生产部署：检查，并在那里报告相同的错误？ – moeabdol

@moeabdo，嗨。我已更新我的问题。是的，在它失败之前，它会通过特定的卡皮斯特拉诺配方。是的，我想，错误是一样的。 – verrom

因此，capistrano报告说您缺少database.yml生产中的数据库适配器。您似乎错误地将postgresql作为数据库名称而不是适配器名称。

在您的database.yml您应该具备以下条件：

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

而在你的Gemfile请确保您有在开发和测试gourp在加工生产时sqlite的宝石，和Postgres宝石（PG），这样的事情：

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

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

Now！运行bundle install然后cap production deploy:check看看是否一切顺利。您可能需要为远程服务器postgres配置用户名和密码。

如果您面临更多麻烦，您可以按照this关于如何将Rails 4应用程序（Nginx + Capistrano + Unicorn）部署到Ubuntu VPS的完整指南。

希望这会有所帮助。

这不起作用..我更新了我的问题。在database.yml中，我已将you_app_name_production更改为数据库名称，给我的托管服务器是什么，对吗？ – verrom

它应该是yurta24_production – moeabdol

我已经将you_app_name_production更改为yurta24_production，并且错误是相同的。 – verrom
