Question

尝试通过gem Capistrano将我的应用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

我的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

更新database.yml后的完整更新错误报告是：

Answer 1

因此，capistrano报告您在database.yml生产中缺少数据库适配器。您似乎错误地将postgresql放置为数据库名称而不是适配器名称。

在您的database.yml中，您应该拥有以下内容：

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

在你的Gemfile中确保你在开发和测试gourp中有sqlite gem，在produciton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 install然后cap production deploy:check查看一切进展顺利。您可能需要为用户名和密码配置远程服务器postgres。

希望这有帮助。
