Question

我继续在webfaction和本地网络服务器上的网络服务器上获得502所有样式表和图片。我不确定我做错了什么？我必须在生产网络服务器上点击3次才能正确加载所有资源。有帮助吗？我的页面上有大图片，但我认为它们不会导致问题。

这些是我在生产服务器上的响应标题

Connection:keep-alive
Content-Encoding:gzip
Content-Type:text/html; charset=utf-8
Date:Sun, 08 Dec 2013 07:47:55 GMT
Server:nginx
Transfer-Encoding:chunked
Vary:Accept-Encoding
X-Powered-By:Express

这是我在节点上的app.js.

var pagejs= '../routes';
var express = require('express')
  , home = require(pagejs)
  , user = require(pagejs+'/user')
  , http = require('http')
  , path = require('path')
  , events = require(pagejs+'/events')
  , contact= require(pagejs+'/contact')
  , abouttedx = require(pagejs+'/about')
  , sponsor = require(pagejs+'/sponsors')
  , gzippo = require('gzippo');

var app = express();

function viewConfig(app){
  app.set('views', __dirname + './../views');
  app.set('view engine', 'jade');

  //app.use(express.favicon());
  app.use(express.favicon(path.join(__dirname + './../public/images/favicon.ico')));
  app.use(express.logger('dev'));
//app.use(express.bodyParser());
  app.use(express.json());
  app.use(express.urlencoded());
  app.use(express.methodOverride());
  app.use(app.router);
  //app.set('view options', {layout: false });
  //app.use(express.static(path.join(__dirname, './../public')));
  app.use(gzippo.staticGzip(path.join(__dirname, './../public')));
  app.use(gzippo.compress());
  app.set('port', process.env.PORT || 9000);
}

app.configure('production', function(){
    viewConfig(app); 
});

app.configure('development', function(){
  app.use(express.errorHandler()); 
  viewConfig(app);
});

app.get('/', home.index);
app.get('/users', user.list);
app.get('/events', events.eventspage);
app.get('/about', abouttedx.aboutpage);
app.get('/sponsor', sponsor.sponsorpage);
app.get('/contact', contact.contactuspage);


http.createServer(app).listen(app.get('port'), function(){
  console.log("Express server listening on port " + app.get('port'));
});

我假设myapp.com是我们要设置的网络应用程序。

在/etc/nginx/sites-enabled/myapp.com中检查您的服务器配置。适应它类似于此;

server {
  server_name myapp.com;

  # set nginx root to public dir of your express server
  root /var/www/myapp/releases/current/public/;

  index index.html index.htm;

  access_log /var/log/nginx/myapp.access.log;
  error_log  /var/log/nginx/myapp.error.log;

  location ~ ^/(js|css|images|media|system)/ {
    autoindex off;
    add_header Cache-Control public;
    expires 4w;
  }

  location / {
    try_files $uri $uri/index.html @proxy;
  }

  location @proxy {
    # set proxy pass to your node server
    proxy_pass   http://127.0.0.1:3000;
  }
}

测试nginx配置并重新加载;

sudo nginx -t
sudo nginx -s reload

现在nginx收到您的请求并将其代理到您的节点服务器。如果这对您有用，请告诉我。如果它仍然不起作用，您可以共享您的nginx配置。
