我想在Apache服务器上的端口80上运行我的node.js应用程序。我通过Apache尝试了两种方法:
<VirtualHost *:80>
ServerName domainName.com
ServerAlias www.domainName.com
ProxyRequests off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location />
ProxyPass http://domainName:8080
ProxyPassReverse http://domainName:8080
</Location>
</VirtualHost>
当我使用此功能时,我会在Chrome控制台中获得502 proxy error
。服务器找不到我的CSS
和Socket.io
以及其他JS
个文件。
更新:我通过将http://domainName.com:8080/
放在链接前面来解决CSS和普通.js文件的此错误。但socket.io仍存在问题!无法找到Socket.io!
第二种方法是使用http-proxy
模块(这是我找到的例子,请看这篇文章下面的评论):
var http = require('http'),
httpProxy = require('http-proxy'),
proxyServer = httpProxy.createServer ({
hostnameOnly: true,
router: {
'domain.com': '127.0.0.1:81',
'domain.co.uk': '127.0.0.1:82',
'127.0.0.1': '127.0.0.1:83'
}
});
proxyServer.listen(80);
这里解释了:how to put nodejs and apache in the same port 80
我不知道如何让这个代码适用于我的代码,因为我正在使用Express
。
这是我相关的代码部分:
var express = require('express');
var http = require('http');
var io = require('socket.io');
var connect = require('connect');
var sanitize = require('validator').sanitize;
var app = express();
var MemoryStore = express.session.MemoryStore;
var server = http.createServer(app);
var sessionStore = new MemoryStore();
var io = io.listen(server);
app.configure(function() {
//app.use(express.logger());
app.use(express.cookieParser());
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.session({
store: sessionStore,
secret: 'someSecret',
key: 'cookie.sid', maxAge: null }));
});
app.use(app.router);
app.use("/styles", express.static(__dirname + '/styles'));
app.use("/images", express.static(__dirname + '/styles/images'));
app.use("/js", express.static(__dirname + '/js'));
// routing
app.get('/', function (req, res) {
res.sendfile(__dirname + '/index.html');
});
server.listen(8080);
我更喜欢第二种方法,所以如果有人能帮助我开始工作,我真的很感激。

为了让socket.io通过具有多个域的节点http-proxy工作,这是我的设置。我不确定它是否是最好的(我希望它能与路由器对象一起使用)但是它可以工作。
var http = require('http'),
httpProxy = require('http-proxy');
httpProxy.setMaxSockets(4096);
var server1 = new httpProxy.HttpProxy({
target: {
host: '127.0.0.1',
port: '3000'
}
});
var server2 = new httpProxy.HttpProxy({
target: {
host: '127.0.0.1',
port: '3001'
}
});
var server = http.createServer(function(req ,res){
switch(req.headers.host){
case 'server1.com':
server1.proxyRequest(req, res);
break;
case 'server2.com':
server2.proxyRequest(req, res);
break;
}
});
server.on('upgrade', function(req, socket, head){
// Cases need only for servers that actually use websockets
switch(req.headers.host){
case 'server1.com':
server1.proxyWebSocketRequest(req, socket, head);
break;
case 'server2.com':
server2.proxyWebSocketRequest(req, socket, head);
break;
}
});
server.listen(80);
