我在apache上有一个运行3站点的linux服务器。我们称它们为railsap1、railsap2和simpleapp。两个rails应用程序都使用了mongrel集群。另一个应用程序只是一个html文件。我在apache中为每个站点设置了不同的虚拟主机文件，并为两个rails站点设置了mongrel_cluster.yml文件（所有这些的代码都在底部）。
通过所有设置，我可以很好地启用apache中的站点。我可以很好地为每个rails站点启动mongrel集群。而且，事实上，在我的浏览器中访问www.simpleapp.com和www.railsapp1.com效果很好。然而，www.railsapp2.com给了我很多麻烦。服务器不会显示railsapp2的代码，而是返回railsapp1的html。如果我在apache中禁用railsapp1，然后转到www.railsapp2.com，服务器现在将返回simpleapp的html。只有在apache中同时禁用railsapp1和railsapp2，服务器才能正确响应www.railsapp2.com上的请求。
有没有想过为什么会这样？

Railsapp1的mongrel_cluster.yml文件：
---
address: 127.0.0.1
log_file: log/mongrel.log
port: 5000
cwd: /home/nudecanaltroll/public_html/railsapp1
environment: production
pid_file: /home/nudecanaltroll/public_html/railsapp1/tmp/pids/mongrel.pid
servers: 3
Railsapp2的mongrel_cluster.yml文件：
---
address: 127.0.0.1
log_file: log/mongrel.log
port: 6000
cwd: /home/nudecanaltroll/public_html/railsapp2

最佳答案
我想出来了。出于未知原因，我需要为railsap2设置serveralias，并在servername前面添加“www.”。因此railsapp2.com vhost文件的顶部现在看起来如下：
<VirtualHost *:80>
ServerName www.railsapp2.com
ServerAlias railsapp2.com
...
出于某种原因，railsapp1不要求这些更改才能正常工作。
