我尝试在我的 Apache 设置中设置乘客，

我收到此错误：

我的虚拟主机 apache 配置：

<VirtualHost *:80>
   ServerName railsapp
   DocumentRoot "/home/username/Sites/railsapp/public "
   RailsEnv development
   PassengerAppRoot /home/username/Sites/railsapp/ 
   <Directory /home/username/Sites/railsapp/public/>
        Allow from all
        Options -MultiViews
        Order allow,deny
   </Directory>
</VirtualHost>

我找不到为什么会出现此错误。如果我用 WEBRick 运行应用程序，一切正常。

感谢您的帮助。

【问题讨论】：

你看过这个答案吗>stackoverflow.com/questions/2732963/…？听起来很像你遇到的问题
此外，Apache 2.4 的 VHost Directory 部分应该看起来像 ``` AllowOverride None 要求所有授予 ``` 很难判断您是否使用 2.2。或 2.4。我在这里只提到这一点是因为我在使用 apache 2.4 配置Passenger 时遇到了一些问题，这是解决方案的一部分

标签： ruby-on-rails-3 apache2 passenger

【解决方案1】：

/home/username/Sites/railsapp/config/environments 中有一个名为 production.rb 的文件吗？由于Passenger 正在运行RAILS_ENV 生产，这似乎缺失了。

WEBrick 将在该文件夹中使用 development.rb，因为那是正在运行的 RAILS_ENV。

【讨论】：

是的，我的配置/环境中有一个 production.rb，该站点在带有乘客和 apache 的生产主机上工作。但我不想再使用 WEBrick，这就是我想安装 Apache + Passenger 的原因。我在我的虚拟主机配置中也指定了 RailsEnv

【解决方案2】：

您的DocumentRoot 包含一个空格。

"/home/username/Sites/railsapp/public "

我建议不要引用这个字符串。

/home/username/Sites/railsapp/public

【讨论】：

是的，对不起，我的错误，我删除了“”，我也得到了同样的错误
