Thin / Capistrano无法连接到数据库

问题描述

我正在尝试将Ruby on Rails应用程序设置为部署到精简集群。当我使用 bundle exec手动启动服务器上的精简集群时，thin start -C config / thin.yml 一切正常。但是，当我通过Capistrano运行相同的命令时，它就会死掉，并且日志显示：

I'm trying to setup my Ruby on Rails application to deploy to a Thin cluster. When I manually start the thin cluster on the server using bundle exec thin start -C config/thin.yml everything works fine. However when I run the same command via Capistrano it just dies and the log displays:

/shared/bundle/ruby/1.9.1/gems /activerecord-3.2.6/lib/active_record/connection_adapters/abstract/connection_specification.rb:45：在`resolve_hash_connection'中：数据库配置未指定适配器（ActiveRecord :: AdapterNotSpecified）

我很茫然，我使用capistrano脚本中定义的用户帐户登录服务器。

I'm at a loss, I log into the server using the same user account as defined in the capistrano script.

我capistrano瘦任务：

My capistrano Thin tasks:

  namespace :deploy do
    task :start do
      run "cd #{current_path}; bundle exec thin start -C config/thin.yml"
    end
    task :stop do
      run "cd #{current_path}; bundle exec thin stop -C config/thin.yml"
    end
    task :restart do
      run "cd #{current_path}; bundle exec thin restart -C config/thin.yml"
    end
  end

这是我的thin.yml：

Here is my thin.yml:

---
chdir: /var/www/rails/myapp/current
environment: staging
address: 0.0.0.0
port: 3000
timeout: 30
log: log/thin.log
pid: tmp/pids/thin.pid
max_conns: 1024
max_persistent_conns: 512
require: []
wait: 30
servers: 2
daemonize: true

任何帮助将不胜感激

推荐答案

我需要在每个步骤上明确设置RAILS_ENV

I needed to explicitly set the RAILS_ENV on each step.

运行 cd＃{current_path};。 RAILS_ENV =＃{rails_env}捆绑执行精简启动-C config / thin.yml

Capistrano似乎没有能力我们的环境变量

It doesn't seem that Capistrano is picking up our environment variable
