工头只显示“开始机智pid＃”而没有别的 [英] foreman only shows line with “started wit pid #” and nothing else

问题描述

 >当运行领班时，我会得到以下结果：工头开始
 16:47:56 web.1 |以pid开头27122 
  

只有当我停止它时（通过ctrl-c）它才会显示我缺少的东西：

  ^ CSIGINT收到
 16:49:26 system |发送SIGTERM到所有进程
 16:49:26 web.1 | =>启动Thin 
 16:49:26 web.1 | => Rails 3.0.0应用程序在http://0.0.0.0:5000 
 16:49:26 web.1 | =>用-d呼叫以分离
 16:49:26 web.1 | => Ctrl-C关闭服务器
 16:49:26 web.1 | >>瘦网络服务器（v1.3.1 codename Triple Espresso）
 16:49:26 web.1 | >>最大连接数设置为1024 
 16:49:26 web.1 | >>听取0.0.0.0:5000，CTRL + C停止
 16:49:26 web.1 | >>停止... 
 16:49:26 web.1 |退出
 16:49:26 web.1 | >>停止... 
  

我该如何解决它？

1. 解决方案

从 https://github.com/ddollar/foreman/wiki/Missing-Output ： b
$ b

如果您没有看到程序的任何输出，则可能有
的机会缓冲标准输出。 Ruby默认缓冲stdout。要
禁用此行为，请尽早在
程序中添加此代码：

 ＃ruby 
 $ stdout.sync = true 
  

通过 heroku toolbelt软件包安装工头

但我仍然不知道发生了什么，也不知道为什么以上两种方式解决了这个问题......

When I run foreman I get the following:

 > foreman start
 16:47:56 web.1     | started with pid 27122

Only if I stop it (via ctrl-c) it shows me what is missing:

^CSIGINT received
16:49:26 system    | sending SIGTERM to all processes
16:49:26 web.1     | => Booting Thin
16:49:26 web.1     | => Rails 3.0.0 application starting in development on http://0.0.0.0:5000
16:49:26 web.1     | => Call with -d to detach
16:49:26 web.1     | => Ctrl-C to shutdown server
16:49:26 web.1     | >> Thin web server (v1.3.1 codename Triple Espresso)
16:49:26 web.1     | >> Maximum connections set to 1024
16:49:26 web.1     | >> Listening on 0.0.0.0:5000, CTRL+C to stop
16:49:26 web.1     | >> Stopping ...
16:49:26 web.1     | Exiting
16:49:26 web.1     | >> Stopping ...

How do I fix it?

解决方案

I’ve been able to resolve this issue by 2 different ways:

1. From https://github.com/ddollar/foreman/wiki/Missing-Output:

   If you are not seeing any output from your program, there is a likely chance that it is buffering stdout. Ruby buffers stdout by default. To disable this behavior, add this code as early as possible in your program:

   # ruby
   $stdout.sync = true
   

2. By installing foreman via the heroku toolbelt package

But I still don’t know what’s happening nor why this 2 ways above resolved the issue…
