I have already added the HTTP TCP Port 80 to the inbound rules, but I still get the error:

You probably have to run your node.js script with sudo as you want to listen on port 80.
You cannot run a process that listens on low ports (below 1024) without root privileges.
You either try to run as sudo, as stated above, or start to use a reverse proxy (nginx for instance), start the process on another port and use the reverse proxy to forward the calls from port 80 to whatever port you started the process on.
The error code EACCES means you don't have proper permissions to run applications on that port. On Linux systems, any port below 1024 requires root access.
you need to use reverse proxy to forward the calls from port 80 to 8080 for example.

So, I'm really new to node and I feel like this might be something very simple but I can't figure it out. I installed the dependencies but when I try to start the server by doing "node server" I get this error:

Your 3001 port is already used by some service, please change the port
var http = require('http');
//create a server object:
http.createServer(function (req, res) {
res.write('Hello World!'); //write a response to the client
res.end();
}).listen(8080); //the server object listens on port 8080
You can use these commands to check what ports are being used:
1. sudo lsof -i -P -n | grep LISTEN
2. netstat -tulpn | grep LISTEN
You can kill that process number using
sudo kill -9 process_number
Your 3001 port is in use. you should use another port or kill 3001 port and then use it.
for example
sudo kill -9 $(sudo lsof -t -i:3001)

Your site.js tries to listen twice on that port or something (another process) is already listening on port 3000. Find the service and stop/kill it. This command should help: lsof -i | grep 3000
Try running killall node, then node site.js again. If that doesn't work, at least you can rule out Node from the cause of this.
Your site is listening twice to that port. You can check in your code whether you have 2 instructions .listen()
I can't understand one thing- does NodeJS allow to listen to custom hostname? Not localhost. Because when I listen to my website url (example.com), I'm getting the following error:
Error: listen EADDRNOTAVAIL example.com ip-address:1000 at

Why does it happend? And can I listen for POST messages from external site URL?
Why does it happend?
This happens because the hostname and port you requested isn't available to you.
can I listen for POST messages from external site URL?
No, You can't. server.listen() accepts hostname and port
Begin accepting connections on the specified port and hostname. If the hostname is omitted, the server will accept connections on any IPv6 address (::) when IPv6 is available, or any IPv4 address (0.0.0.0) otherwise. Omit the port argument, or use a port value of 0, to have the operating system assign a random port, which can be retrieved by using server.address().port after the 'listening' event has been emitted.
And further digging into list of Node.js Common System Errors docs and exhaustive list, It is clear that, Address not available was the case.
EADDRNOTAVAIL Address not available (POSIX.1).
When I try to start node on port 80, the error tells me that the port is in use. I imagine that's Apache.
What is the proper way to "take over" port 80, and keep it that way after a server restart?
(Linux xxxx.__.com 2.6.32-5-amd64 #1 SMP Tue Jun 14 09:42:28 UTC 2011 x86_64 GNU/Linux)
you can use ip tables to map port 80 to 8000
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8000
to make it permanent
sudo sh -c "iptables-save > /etc/iptables.rules"
and add
pre-up iptables-restore < /etc/iptables.rules
to your /etc/network/interfaces
To take over port 80 when another process is listening on it, you must kill the process (or somehow tell it to stop listening). To ensure that Apache doesn't try to listen on port 80 again the next time it starts, you need to edit its configuration or prevent it from starting up.
To see which process is listening on port 80, run sudo netstat -ntap and look for the row with Local Address ending in port :80. The PID of the process (and the name) is in the far right column.
you can use node.js with node-http-proxy check this link How to use vhosts alongside node-http-proxy? and
How do I run Node.js on port 80?

A constantly running unused apache maybe a security hole, in any case no sense in running unused services.
On the chance you're on ubuntu, this what I used..
sudo service apache2 stop
sudo update-rc.d apache2 remove
You can access port 80 once you stop the service currently using it.
In your case, follow these steps:
1) Use systemctl to stop apache2:
sudo systemctl stop apache2
2) Check apache2 status:
sudo systemctl status apache2
Or just by entering http://localhost in your browser. If you get an error, you are good to go.
ERR_CONNECTION_REFUSED
3) Now start your NodeJS server on port 80.
4) You can access your server at http://localhost
UPDATE
If you are seeing errors on your console, try node preceding with sudo
For eg. sudo node server.js
Here are the errors
events.js:137
throw er; // Unhandled 'error' event
