Ruby Unicorn和Sinatra未记录日志的nginx服务器崩溃

我有一个使用Ruby、Sinatra、Unicorn和nginx的服务器。我最近经历了一次崩溃，在终端中运行时重新生成了问题，我可以看到它生成了以下崩溃日志：

/Users/Andrew/.rvm/gems/ruby-2.3.0/gems/tweetstream-2.6.1/lib/tweetstream/client.rb:449:in `block in connect': Failed to reconnect after 6 tries. (TweetStream::ReconnectError)
    from /Users/Andrew/.rvm/gems/ruby-2.3.0/gems/em-twitter-0.3.5/lib/em-twitter/connection.rb:297:in `invoke_callback'

    from server.rb:234:in `<main>'

但是我转到这两个目录，访问日志只显示所有请求，正如我所期望的，错误日志是空的

如果我的日志存储在其他地方，我如何确定它在哪里？或者，如果出于某种原因没有记录崩溃，我如何确保它是这样呢？

我建议您在

unicorn.rb

文件中为unicorn设置

stderr

和

stdout

日志

# note the trailing slash in this example
@dir = File.dirname(__FILE__) + '/'
