Question

在Ubuntu hardy slice上升级到Rails 2.3.2和Passenger 2.2.4 使用Apache2的slicehost

我在Apache error.log中遇到了上面讨论过的错误 system / var / logs / apache2 /

它让我疯狂，在浏览器上，有时它的节目和时间刷新，应用程序错误500经常出现。任何方向？

Answer 1

看起来您所拥有的错误已合并到Passenger master但尚未发布。您可以通过从以下存储库中检查Passenger out来尝试：

http://github.com/FooBarWidget/passenger/tree/master

一旦你检查出来，你想运行：

./bin/passenger-install-apache2-module

用于Apache Passenger，或者：

./bin/passenger-install-nginx-module

为Nginx乘客。由于这个特殊问题得到解决，它应该适合你。

Answer 2

我也有这个问题并通过从乘客2.1.2升级到乘客2.2.15来修复它。

要明确这不是铁路问题，这是一个乘客的错误。

错误日志输出：

[ pid=13571 file=Hooks.cpp:508 time=2010-04-28 17:46:16.878 ]:
  Backend process 22235 did not return a valid HTTP response. It returned no data.

Answer 3

虽然此错误仍在发生，但我更新了Passenger 2.2.7版。我发现在我的Apache配置中更新TimeOut和KeepAliveTimeout似乎解决了这个问题。（他们分别从1和2变为10和20）。希望能帮助别人！

Answer 4

我刚碰到这个。事实证明这是服务器上DNS破坏的症状。我认为由于飓风桑迪，它的名字服务器已经下线了。因此，如果您遇到此问题，请检查您的网络名称解析是否正常工作！

Passenger RequestHandler中的异常Errno :: EPIPE（断管）
