在Ubuntu 12.04 for Rails 3.2.8環境下設置Nginx和Passenger環境

Question

我是一個新手，喜歡語言和開發環境。然而，當我不使用PostgreSQL和/或Heroku的時候，我試圖將一個新的應用程序推送到生產環境，我感到非常沮喪。

由於工作相關的原因，我們使用一個以MySQL作爲數據庫的rackspace雲服務器。

我的挫折感來自搭乘乘客和Nginx。我已經按照Ryan的Railscasts上的deploying to vps和this教程。

我可以通過在服務器上安裝ruby，mysql，passenger，Nginx，依賴項和rails。但是當我嘗試啓動Nginx時，沒有任何反應。當我說沒有任何反應時，我的意思是我沒有任何跡象表明它正在運行。我將瀏覽器指向IP地址，並在瀏覽器中出現「此網頁不可用」的標準錯誤。我看過錯誤日誌，它是空白的。我還沒有部署我的應用程序...只是想看看Nginx的默認屏幕。

任何想法？我猜測在配置Nginx時我缺少一個關鍵步驟，我只是不知道它是什麼。

從我的博客文章這是在這個確切的設置http://blog.nikoroberts.com/post/45834702235/setting-up-a-rails-32-server-in-the-rackspace

你至少缺少 passenger_enabled on;幾乎

我的nginx.conf

worker_processes 4; 

events { 
    worker_connections 1024; 
} 

http { 
    passenger_root /home/deployer/.rvm/gems/ruby-1.9.3-p194/gems/passenger-3.0.17; 
    passenger_ruby /home/deployer/.rvm/wrappers/ruby-1.9.3-p194/ruby; 

    include  mime.types; 
    default_type application/octet-stream; 

    sendfile  on; 

    keepalive_timeout 65; 

    client_max_body_size 5M; 

    gzip on; 
    gzip_http_version 1.1;

    gzip_vary on;

    passenger_default_user deployer;

    passenger_pool_idle_time 1000; 

    server { 
    listen 80; 
    charset utf-8; 
    server_name localhost; 
    root /var/www/contactguru/current/public; 
    passenger_enabled on; 
    rails_env production;

    rails_spawn_method smart; 
    rails_app_spawner_idle_time 0;

    location ~ ^/(assets)/ {

     gzip_static on; 
     expires max;
