使用 Apache2 和Passenger 部署Rails 应用程序时出现404 Not found 错误 [英] 404 Not found error in deploying a Rails app with Apache2 and Passenger

问题描述

可能是一个简单的调整问题，但我不知道出了什么问题.

probably a matter of simple adjustment but I have no idea whats going wrong.

我想要一个主机作为我的 rails 应用程序的服务器，该应用程序是使用 Capistrano 3.2.1 部署的.这是一台运行 Apache/2.2.15 的 Unix 机器，名为 eng-perf(公司内部机器，因此目前没有 www.address.com 语法).

I want a host to be a server for my rails application, which was deployed using Capistrano 3.2.1. This is a Unix machine running Apache/2.2.15, named eng-perf (corporate internal machine, so no www.address.com syntax at the moment).

我按照本指南进行了整个安装过程没有任何麻烦.我编辑了配置文件，使其看起来像这样:

I followed this guide and the entire installation process went without any trouble. I edited the configuration file so that it looks like this:

<VirtualHost *:80>
  ServerName eng-perf
  # !!! Be sure to point DocumentRoot to 'public'!
  DocumentRoot /var/www/eng_performance/current/public/
  <Directory /var/www/eng-performance/current/public/>
     # This relaxes Apache security settings.
     AllowOverride all
     # MultiViews must be turned off.
     Options -MultiViews
     # Uncomment this if you're on Apache >= 2.4:
     #Require all granted
  </Directory>
</VirtualHost>

这给了我这个错误:

未找到

在此服务器上找不到请求的 URL/.

The requested URL / was not found on this server.

接下来，我尝试按照指南创建虚拟应用程序 - as在这里解释，并将配置文件更改为:

Next, I tried following the guide by creating the dummies application- as explained here, and changed the configuration file to be:

<VirtualHost *:80>
  ServerName eng-perf
  # !!! Be sure to point DocumentRoot to 'public'!
  DocumentRoot /var/www/rack_example/public/
  <Directory /var/www/rack_exmaple/public/>
     # This relaxes Apache security settings.
     AllowOverride all
     # MultiViews must be turned off.
     Options -MultiViews
     # Uncomment this if you're on Apache >= 2.4:
     #Require all granted
  </Directory>
</VirtualHost>

这导致了完全相同的 Not Found 错误.所以，我想我错过了一些非常简单的东西..

That resulted the exact same Not Found error. So, I guess I'm missing something quite simple..

另外，我尝试重启apache服务器，提示:httpd:无法可靠地确定服务器的完全限定域名，使用.machine.ip.addr作为ServerName因此，我将 ServerName 字段更改为该地址 - 但这也不起作用.

Also, I tried to restart the apache server and prompted: httpd: Could not reliably determine the server's fully qualified domain name, using the.machine.ip.addr for ServerName As a result I changed the ServerName field to be this address- but that didn't work either.

更新:

按照 Rich 的建议，我更新了配置文件，所以现在我得到了这个输出:

Following Rich's advise, I updated the configuration file so now I get this output:

config.ru:2: syntax error, unexpected tIDENTIFIER, expecting =>
... [200, { "Content-Type => "text/html" }, ["hello <b>world</b...

推荐答案

我们使用以下内容:

#etc/apache2/apache2.conf
<VirtualHost *:80>
   ServerName eng-perf.com

   DocumentRoot /var/www/rack_example/plublic
   <Directory /var/www/rack_example/public>
      Allow from all
      Options -MultiViews
   </Directory>

   ScriptAlias /cgi-bin/ /usr/lib/cgi-bin
   <Directory "/usr/lib/cgi-bin">
       AllowOverride None
       Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
       Order allow,deny
       Allow from all
   </Directory>
</VirtualHost>

我怀疑问题在于您没有正确调用您的域.它会混淆它在请求中寻找的内容

I suspect the problem lies with your not calling your domain correctly. It's going to get confused about what it's looking for on the request
