推荐答案

错误说：请检查是否有崩溃错误
这个应用程序。

The error says : "please check whether there are crashing bugs in this application."

你有没有尝试删除您的Web应用程序，并用一个简单的index.html页面试试？

Did you try to remove your web application, and try with a simple index.html page ?

如果它的稳定之后，问题并非来自乘客的配置，而是在你的应用程序。
在这种情况下，通过在每个步骤有用户的交互应用程序中添加loger增加日志详细程度

If it's stable then the issue doesn't come from Passenger config, but rather in your application. In this case, increase the log verbosity by adding loger in your application at each step there is a user interaction.

还您正在使用的Apache2-mpm- prefork而不是Apache2的-MPM-工人检查。
这Apache2的-MPM-工人是一个多线程版本，可惜乘客不支持多线程与Apache2的。
试试下面的命令来请检查是否是安装还是不：

Check also that you are using apache2-mpm-prefork and not apache2-mpm-worker. This apache2-mpm-worker is a multi-thread version, and unfortunately passenger doesn't support multi-thread with apache2. Try following commands to check wether it is installed or not :

aptitude show apache2-mpm-worker
aptitude show apache2-mpm-prefork

这是什么命令显示？

What does this command shows ?

passenger-install-apache2-module

您应该拥有的一切绿色的。

You should have everything green.
