在Rails应用程序中启用PHP文件夹？

我需要通过一些JS ajax调用在Rails应用程序中运行一些用 PHP编写的脚本.我有一个跨域问题,我的脚本在localhost / scripts上处于活动状态,我的应用程序在localhost：3000 / myapplication上处于活动状态.对localhost的Ajax请求返回跨域错误.

我能够实现jsonp解决方法,它工作正常,但我理想的是想从rails文件夹中访问PHP文件.我读到可以配置apache服务器以在框架内的文件夹上启用PHP.我在Linux上运行Apache2.

Attempted solution
我不是100％确定在哪里找到.htaccess文件,所以我只在目录中创建了一个(public / PHP-scripts).不确定这是否有效……

尝试2：
我似乎无法正确配置我的服务器：
我安装了所有乘客组件并修改了我的文件：/ etc / apache2 / sites-available / default

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.1.3/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.1.3
PassengerRuby /usr/bin/ruby1.8
<VirtualHost *:80>
        ServerName myservername
        DocumentRoot /var/www/myapp/public

        <Directory /var/www/myapp/public>
                Allow from all
                Options -MultiViews
        </Directory>
</VirtualHost>

<VirtualHost *:80>
        ServerAdmin webmaster@localhost

        DocumentRoot /var/www/

        <Directory /var/www/>
          Options FollowSymLinks
          AllowOverride None
        </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>

        ErrorLog ${APACHE_LOG_DIR}/error.log

        # Possible values include: debug,info,notice,warn,error,crit,# alert,emerg.
        LogLevel warn

        CustomLog ${APACHE_LOG_DIR}/access.log combined

        Alias /doc/ "/usr/share/doc/"
        <Directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks
         AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
        </Directory>

</VirtualHost>

然后我重新启动了服务器.我错过了什么？
我导航到myservername /和myservername / myapp并获得Forbidden消息
