为什么我在日志中看不到任何Rails特定条目？

我正在使用Puma 2.7.1和Nginx代理,在正常的Debian盒子上,通过RVM没什么花哨的,ruby 1.9.3.

我的美洲狮配置：

#!/usr/bin/env puma
environment 'sandBox'
bind 'unix://tmp/puma.sock'
stdout_redirect 'log/puma.log','log/puma_error.log',true
pidfile 'tmp/pids/puma.pid'
state_path 'tmp/pids/puma.state'
daemonize true 
workers 4

我开始彪马通过：

bundle exec puma -C config/puma/config.rb

我知道了：

[23664] Puma starting in cluster mode...
[23664] * Version 2.7.1,codename: Earl of Sandwich Partition
[23664] * Min threads: 0,max threads: 16
[23664] * Environment: sandBox
[23664] * Process workers: 4
[23664] * Phased restart available
[23664] * Listening on unix://tmp/puma.sock
[23664] * Daemonizing...

我跑：

tail -f log/puma*

我知道了：

==> log/puma_error.log <==
X-Accel-Mapping header missing
=== puma startup: 2014-02-13 14:08:52 +0100 ===
[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.

==> log/puma.log <==
=== puma startup: 2014-02-13 14:08:52 +0100 ===
[23670] - Worker 23678 booted,phase: 0
[23670] - Worker 23674 booted,phase: 0
[23670] - Worker 23686 booted,phase: 0
[23670] - Worker 23682 booted,phase: 0

但我没有看到任何更多的日志,没有任何应用程序相关.

当应用程序引发异常时,我在日志中什么也得不到……“tabula rasa”
