主持一個靜態Node.js頁面

Question

我想了解Node.js，我已經寫了一個簡單的Node.js page與快遞和ejs按照在Lynda.com指南。我將該頁面託管在Amazon AWS服務器上，並安裝了Nginx。當我運行節點應用程序時，我可以訪問IP：3000的頁面。我還設置了Nginx，遵循幾個不同的指南將服務器IP /重定向到端口3000.然而，當我嘗試訪問IP /的頁面時，沒有任何圖像或CSS出現。

我在過去爲使用Ruby on Rails的學校設置了一些網頁，我假設這是一個開發vs生產問題。我發現的大多數指南/說明只是展示如何設置Nginx來獲取一個簡單的Hello World應用程序，而不需要任何圖像或CSS。有人可以指導我去適當的資源來完成我在這裏要做的事嗎？

編輯：這是我的app.js和我的兩個路線 app.js

var express = require('express'); 
var reload = require('reload'); 
var app = express(); 
var clientFile = require('./data/clients.json'); 
var instructionFile = require('./data/instructions.json'); 

app.set('port', process.env.PORT || 3000); 
app.set('clientData', clientFile); 
app.set('instructionData', instructionFile); 
app.set('view engine', 'ejs'); 
app.set('views', './views'); 

app.locals.siteTitle = 'Roux Meetups'; 

app.use(express.static('./public')); 
app.use(require('./routes/index')); 
app.use(require('./routes/instructions')); 

var server = app.listen(app.get('port'), function() { 
    console.log('Listening on port ' + app.get('port')); 
}); 

reload(server, app); 

var express = require('express'); 
var router = express.Router(); 

路線1

router.get('/', function(req, res) { 
    var clients = req.app.get('clientData'); 
    var clientPhotos = clients.images; 
    var clientAddresses = clients.sites; 

    res.render('index', { 
    pageTitle: 'Home', 
    clients: clientPhotos, 
    sites: clientAddresses, 
    pageID: 'home' 
    }); 
}); 

module.exports = router; 

路線2

var express = require('express'); 
var router = express.Router(); 

router.get('/instructions', function(req, res) { 
    var clients = req.app.get('clientData'); 
    var clientPhotos = clients.images; 
    var clientAddresses = clients.sites; 

    var instructions = req.app.get('instructionData'); 
    var instructPhotos = instructions.images; 

    res.render('instructions', { 
    pageTitle: 'Instructions', 
    clients: clientPhotos, 
    sites: clientAddresses, 
    instructs: instructPhotos, 
    pageID: 'instructions' 
    }); 
}); 

module.exports = router; 

我也只能編輯我的/ etc/nginx/sites-available/nginx的默認值爲

server { 
listen 80 default_server; 
listen[::]:80 default_server; 

root /var/www/html; 

index index.html index.html index.nginx-devian.html; 

server_name _; 

location/{ 
    proxy_pass http://localhost:3000; 
    try_files $uri $uri/ = 404; 
} 
}
