我只是通过 SSH 连接到我的 Ubuntu 14.04 服务器实例,试图引导我的 Unicorn 服务器以运行 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,为什么找不到 dangconfig.ru文件呢?它就在那里,用于本地开发目的 - 如果我只是在没有标志的情况下启动 Unicorn,它会发现它很好,就好像它在开发环境中一样。

bundle exec unicorn

正常(开发,而不是生产,这是我在这个环境中需要的)引导 OK:

好的,所以现在我将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working_directory此错误消息中的:

/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)

我错误地配置了我的config/unicorn.rb.

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

新的配置是:

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

  1. Unicorn 是一个机架服务器。Unicorn 会查找config.rurackup 使用的文件APP_ROOT

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