Question

我只是通过SSH连接到我的Ubuntu 14.04服务器实例，试图为我的Unicorn服务器引导Rails 4.2应用程序。

cd /home/sh0/app/current/api
bundle exec unicorn -E production -c /home/sh0/app/current/api/config/unicorn.rb

但它失败了！

/usr/local/lib/ruby/gems/2.0.0/gems/unicorn-4.9.0/lib/unicorn/configurator.rb:657:in `parse_rackup_file': rackup file (config.ru) not readable (ArgumentError)
        from /usr/local/lib/ruby/gems/2.0.0/gems/unicorn-4.9.0/lib/unicorn/configurator.rb:77:in `reload'
        from /usr/local/lib/ruby/gems/2.0.0/gems/unicorn-4.9.0/lib/unicorn/configurator.rb:68:in `initialize'
        from /usr/local/lib/ruby/gems/2.0.0/gems/unicorn-4.9.0/lib/unicorn/http_server.rb:100:in `new'
        from /usr/local/lib/ruby/gems/2.0.0/gems/unicorn-4.9.0/lib/unicorn/http_server.rb:100:in `initialize'
        from /usr/local/lib/ruby/gems/2.0.0/gems/unicorn-4.9.0/bin/unicorn:126:in `new'
        from /usr/local/lib/ruby/gems/2.0.0/gems/unicorn-4.9.0/bin/unicorn:126:in `<top (required)>'
        from /home/sh0/app/releases/20150514055558/api/bin/unicorn:16:in `load'
        from /home/sh0/app/releases/20150514055558/api/bin/unicorn:16:in `<main>'

那么，为什么不它找到了dang config.ru文件？它就在那里，为了本地开发目的 - 如果我只是在没有标志的情况下启动Unicorn，它会发现它很好，就好像它处于开发环境中一样。

bundle exec unicorn

正常（开发，不是我在这种环境中需要的生产）bootstrap OK：

好的，现在我会尝试在这两次尝试之间做点什么。

在我的远程服务器上：

cd /home/sh0/app/current/api
unicorn -c config/unicorn.rb

请注意此错误消息中的working_directory：

/usr/local/lib/ruby/gems/2.0.0/gems/unicorn-4.9.0/lib/unicorn/configurator.rb:539:in `working_directory': config_file=config/unicorn.rb would not be accessible in working_directory=/home/sh0/app/current (ArgumentError)

Answer 1

我错误配置了config/unicorn.rb。

My Rails项目不在我的存储库的基础上，因此我需要更新该文件中默认指定的working_directory。

新配置是：

working_directory "/home/sh0/app/current/api"

Answer 2

Unicorn是一个机架式服务器。 Unicorn将在config.ru

APP_ROOT

在您的生产服务器中，/home/sh0/app/current/api/config.ru是否存在？

为什么即使我指定配置，Unicorn仍在寻找rackup文件（config.ru）？
