Sharing Windows Server with Nodebb and Wordpress

RichG

I am almost 100% sure that I need a proxy server in-front of IIS to traffic the http request, but now we get into another level of complexity. That is why I hate Windows. I am going to explore finding a Nodejs app to set on port 80 and do the routing to IIS and noebb. Just to keep things simple. KISS.

Okay. First off: Change the secret in your config.json immediately, you should never post it anywhere online.
You should change the url here to "http://theamericanbulletin.com/forum". That way, NodeBB can deliver static resources with the correct path (remember, the client will request each resource based on this address which gets then parsed in the IIS).

What are the rewrite rules shown in the ISS console?

Done. I will try your suggestion. The rules...

@Moritz-Friedrich... "You should change the url here to "http://theamericanbulletin.com/forum"". Sorry.... no go. When I make your suggested change the nodebb start listening on it's default port 4567. Even changing web.config fro, :8080 to :4567 does not do the trick. and when access the forum from http:thaamericanbulletin.com:4567 then produces this result.... "/forum is append to 'all' the paths confusing nodebb. I think I need to write a 'small' node proxy to sit on :80. Isn't that where node shines...

It's important that you know what these URLs mean. Look at this:

Client requests theamericanbulletin.com/forum.
IIS revieves a request for theamericanbulletin.com/forum and routes it to localhost:8080 or localhost:4567.
NodeBB recieves a request from the client and uses theamericanbulletin.com/forum as a base URL to construct its relative links, eg. theamericanbulletin.com/forum/category/1/test.
The client recieves the NodeBB page from theamericanbulletin.com/forum.

That means, you have to configure the IIS to rewrite theamericanbulletin.com/forum to localhost:4567 (or :8080 respectively, that doesn't really matter apart from convention). NodeBB instead will think it sits on theamericanbulletin.com/forum all along.
If you need further help setting up the rewrite rules, let me know.

Best of luck to you @RichG. I did quite a bit of windows admin with IIS back in the day but I couldn't explain to you now how to do it without being on your system.

If you still can't get IIS to play nice, may I suggest giving WAMP a try? It's basically the most popular linux web server: Apache, on windows. It will allow you to stick with windows but also use the suggestions and instructions from the nodebb documentation to get your proxy pass setup correctly. Additionally, configuring wordpress to use Apache instead of IIS is trivial.

If you decide to go this route I can walk you through setting up apache and the vhosts required, just start a chat with me here.

@Moritz-Friedrich @KingCat You guys are awesome.

@Julian if I have some time this weekend, I could write a setup guide for IIS w/ screenshots, if you guys want it for the docs? With a big warning at the top, "Stop reading, use linux!"

julian

Sounds good! We'd love to add it to the setup guides in our documentation portal!

@KingCat @Moritz-Friedrich @nhl-pl @julian Thank you all for your help and support. I have just completed setting up a nodejs proxy server sitting on port 80. The thought of sending anyone back into the burning building and horrors of dealing with the windows platform was just too much for me. I just could not allow you gallant people to relive the scars that took so many of you to years to heal.

I choose this solution because it distances the proxy from whatever server happens to be running. If IIS is listening on port 8001, and the nodeBB is listening on port 8080 so be it. I don't care... do not want to deal with a windows proxy, and the horrors of rewrite and all the other super secret your in the club handshaking. I am a programer.... I want control to change things as I see fit... dependent on none other that myself to achieve my goals.

Holy crap. The hours spent reading... the hundreds of posts I have read just to get windows to hand 'forum.theamercianbulletin.com' to port 8080 was mind numbing. And there still was not a clear solution. It maybe easier with linux... but still tinkering with Linux is still... tinkering with Linux... and not the proper solution ( IMHO). Anyway... this is the code that solved my problem. I will be making a post here to explain how everything works and all the steps needed to help others with this solution. Again... thanks for all the help, effort, and thoughts. Just a great group of people.....

ISS wordpress is now listening on 8081
Nodebb is listening on 8080
Proxy listening on 80

This code is rough and needs some clean-up and featurers added to it, but is is working as I write this post.

var util = require('util'),
http = require('http'),
url = require('url'),
domain = require('domain')
httpProxy = require('../../lib/http-proxy'),
proxy = httpProxy.createProxyServer({});
serverDomain = domain.create();
serverDomain.run(function () {http.createServer(function(req, res)
{
var reqd = domain.create()
reqd.add(req)
reqd.add(res)
// On error dispose of the domain
reqd.on('error', function (error) {
console.error('Error', error, req.url)
reqd.dispose()
});
var hostname = req.headers.host.split(":")[0];
var pathname = url.parse(req.url).pathname;
switch(hostname)
{
case 'forum.theamericanbulletin.com':
proxy.web(req, res, { target: 'http://localhost:8080' });
break;
default:
proxy.web(req, res, { target: 'http://localhost:8081' });
};
proxy.on('error', function(err, req, res)
{
console.log('Error 500');
});
console.log(hostname);
console.log(pathname);
}).listen(80,function(){
console.log('proxy listening on port 80');
});
});

That would be a great idea. There are still a lot of Windows user out there and your expertise would surly be a help.

I started off this quest with just a simple problem. To have the ability for users to address my nodebb forum (http://theamericanbulletin.com:8080) as (“http://forum.theamericanbulletin.com”). This simple problem turned into a quest through countless videos and reading ( at least fifty) mindnumbing posts on blogs and other forums. I am running a Windows server ( 2008 ) with IIS to service my Wordpress main site. My NodeBB forum is listening on port 8080. All advice was to work within the framework of Windows and IIS, using 'Rewrite', to route traffic on the Server. After days of frustration, I had to come up with a better plan. One that gets me above proprietary nuances. The only way to do that was to get hold of port 80 myself..my own proxy server.. and what better webserver than Nodejs. With little of a search I came accoss this project.

https://github.com/nodejitsu/node-http-proxy

I git cloned the above link.
Renamed the new directory to nodeproxy
e:\nodeproxy> npm install ( pulls all the needed modules)
created a new directory under the new 'nodeproxy' entitled MyProxy
Created the MyProxy.js file ( contents below )
Moved my WordPress to listen on port 8081 in IIS
Started new proxy server (e:\nodeproxy\myproxy> node myproxy.js )
Done!

Some notes about the js file. When I first started I used this post as a guideline. It used a routing table... exactly what I was looking for. Although I was not needing to spin-up three test servers, this provided some insight into the power if this little application. I could, if I wanted to.... spin-up as many listeners as I wanted..... listening on whatever, or as many port(s) as I wanted.

http://stackoverflow.com/questions/25896608/nodejs-routing-table-using-http-proxy

var httpProxy = require("http-proxy");
var url = require("url");
 httpProxy.createServer(function(req, res, proxy) {

var hostname = req.headers.host.split(":")[0];
var pathname = url.parse(req.url).pathname;

// Options for the outgoing proxy request.
var options = { host: hostname };

// Routing logic
if(hostname == "127.0.0.1") {
    options.port = 8083;
} else if(pathname == "/upload") {
    options.port = 8082;
    options.path = "/"; 
} else {
    options.port = 8081;
}
// (add more conditional blocks here)
proxy.proxyRequest(req, res, options);
}).listen(8080);
console.log("Proxy listening on port 8080");
 // We simulate the 3 target applications
var http = require("http");

http.createServer(function(req, res) {
  res.end("Request received on 8081");
 }).listen(8081);

 http.createServer(function(req, res) {
  res.end("Request received on 8082");
 }).listen(8082);

http.createServer(function(req, res) {
res.end("Request received on 8083");
 }).listen(8083);

I modified the above code to tailor it to my routes, but the server kept breaking. The proxy would throw a “socket hang up” when I moved between the Wordpress site and the NodeBB site. The error was not getting caught and the proxy would just break and go back to a system prompt. Another day of research lead me to this post.

http://www.clock.co.uk/blog/preventing-http-raise-hangup-error-on-destroyed-socket-write-from-crashing-your-nodejs-server

It was in this post where the idea of wrapping the proxy-server within a domain arose. Perfect! I can pass the error up to the domain and let it dispose of it while the proxy keeps serving ( at least that's how I think it works). Plus the added benefit of having and overlord (parent) to all the potential listeners that could be spun-up to report to. But that is a whole different subject.

So I added a Domain to the mix and came-up with a working solution. While this only apples to those with 'full' control over their servers, it does add a layer of control over proprietary systems running on your machine, and frees the developer (to a point) from those systems. I do not have to mess with rewrite... or some Apache routine tables. This is 'clean' and simple.

Please feel free to improve on this concept and tighten this up. There is room for lots of improvement here. Please add to the knowledge.
