我有一个 Sinatra 应用程序，我使用 Thin 在 dev/stage 中运行，现在是时候投入生产了，我开始检查如何在 apache 中与乘客一起服务。
我主要关注
http://recipes.sinatrarb.com/p/deployment/apache_with_passenger http://www.rabblemedia.net/blog/installing-rvm-ruby-on-rails-and-passenger-on-centos-6/ http:// /sergiy.kyrylkov.name/2012/02/26/phusion-passenger-with-apache-on-rhel-6-centos-6-sl-6-with-selinux/
我的本地机器正在运行 fedora 16、apache 2.2、ruby 1.9+
我安装了乘客
gem install passenger
接着
passenger-install-apache2-module
几乎按照说明进行操作，例如添加乘客模块
#mod_rails passenger
LoadModule passenger_module /home/orlybg/.gem/ruby/1.9.1/gems/passenger-4.0.5/libout/apache2/mod_passenger.so
PassengerRoot /home/orlybg/.gem/ruby/1.9.1/gems/passenger-4.0.5
PassengerDefaultRuby /usr/bin/ruby
这是我的虚拟主机：
<VirtualHost *:80>
DocumentRoot "/var/www/html/billomatic"
ServerName billomatic
RailsEnv development
<Directory "/var/www/html/billomatic">
Options Indexes MultiViews FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
LogLevel debug
ErrorLog "/var/log/httpd/billomatic-error_log"
CustomLog "/var/log/httpd/billomatic-access_log" common
还有我的 config.ru
require 'rubygems'
require 'sinatra'
set :environment, ENV['RACK_ENV'].to_sym
disable :run, :reload
require File.join(File.dirname(__FILE__), 'bill-o-matic.rb')
run Sinatra::Application
当我打
http://billomatic/
我得到了 Fedora 页面的默认 apache，起初抱怨的 vhost 错误日志
==> billomatic_error.log <==
[Wed Jun 05 12:45:42 2013] [error] [client 127.0.0.1] Directory index forbidden by Options directive: /var/www/html/billomatic/
但是后来我只是给了 billomatic 目录 755 许可，并且那里不再出现任何日志，在一般的 apache 日志中，我在重新启动时看到了这个：
==> error_log <==

当我跑
passenger-memory-stats
我明白了：

奇怪的是当我执行
passenger-status
我得到：错误：Phusion Passenger 似乎没有运行。
此外，当我尝试使用 sudo 运行最后一个命令时，系统说找不到该命令。
关于我错过什么/做错了什么的任何线索？
提前致谢。
更新：我还禁用了 SELinux，并在我的 sinatra 项目目录中添加了一个 tmp/restart.txt。
