ruby-on-rails-3 - Ubuntu - Apache - Rails - 乘客 - 生成错误

Question

我有乘客提示的错误:

*** Passenger ERROR (ext/common/ApplicationPool/../SpawnManager.h:220):
Could not start the spawn server: /usr/local/rvm/gems/ruby-1.9.3-head/ruby: No such file or directory (2)
[ pid=8970 thr=139698295748416 file=ext/apache2/Hooks.cpp:865 time=2012-11-07 17:17:32.422 ]: Unexpected error in mod_passenger: Cannot spawn application '/www/lensfinder.se/ruby/lensfinder': Could not read from the spawn server: Connection reset by peer (104)
  Backtrace:
     in 'virtual Passenger::SessionPtr Passenger::ApplicationPool::Client::get(const Passenger::PoolOptions&)' (Client.h:750)
     in 'Passenger::SessionPtr Hooks::getSession(const Passenger::PoolOptions&)' (Hooks.cpp:297)
     in 'int Hooks::handleRequest(request_rec*)' (Hooks.cpp:566)

据我所知，它无法访问/www/lensfinder.se/ruby/lensfinder 尽管它存在。

我在 Phusion Passengers site 上找到了这个常见问题解答

问题是，当我尝试使用该命令时，

passenger-config --root

我明白了:

-bash: /usr/bin/passenger-config: ruby: bad interpreter: No such file or directory

Apache 配置:

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-head/gems/passenger-3.0.12/ext/apache2/mod_passenger.so
   PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-head/gems/passenger-3.0.12
   PassengerRuby /usr/local/rvm/wrappers/ruby-1.9.3-head/ruby

好的，我的猜测是您将Passenger 指向错误的目录。您应该将其指向 public Rails 应用程序的目录。

这是您项目的极简配置，位于 /etc/apache2/sites-available/lensfinder.se :

<VirtualHost 10.0.0.37:80>
  ServerAdmin hostmaster@compartment.se
  ServerName lensfinder.se
  ServerAlias *.lensfinder.se

  DocumentRoot /www/lensfinder.se/ruby/lensfinder/public
  RailsEnv production

  <Directory "/www/lensfinder.se/ruby/lensfinder/public">
    Options FollowSymLinks
    AllowOverride All
    Options -MultiViews
  </Directory>

</VirtualHost>

然后编辑 /etc/apache2/apache2.conf并在文件末尾添加:

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-head/gems/passenger-3.0.12/ext/apache2/mod_passenger.so
PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-head/gems/passenger-3.0.12
PassengerRuby /usr/local/rvm/wrappers/ruby-1.9.3-head/ruby

然后 simlink 您的虚拟主机配置以启用它:

ln -s /etc/apache2/sites-available/lensfinder.se /etc/apache2/sites-enabled/lensfinder.se 

当然重启apache2
