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 /home/sh0/app/releases/20150514055558/api/bin/unicorn:16:in `<main>'
那么,为什么它找不到 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)
