2.untar the package
3.install pcre

download and install it

4.run the command
passenger-install-nginx-module
5.configurations shoule be like below

      listen 80;
      server_name
      root /somewhere/public;   # <--- be sure to point to 'public'!
      passenger_enabled on;
   }

7配置config.ru

注意该文件应该放在public上一层目录，之后require相应的rb文件。这东西log里面还看不到提示，害我搞了半天。

[root@test-pangaeadns1 apps]# cat config.ru
# config.ru

require 'rubygems'
require 'sinatra'
require './app.rb'
run Sinatra::Application
