Error: listen EACCES 0.0.0.0:80 OSx Node.js
Javascriptnode.jsMacosJavascript Problem Overview
I'm following a tutorial in a angularJS book and have to setup a server. This is the server.js file:
var express = require('express');
var app = express();
app.use('/', express.static('./'));
app.listen(80);
I get this error:
$ node server.js
events.js:154
throw er; // Unhandled 'error' event
^
Error: listen EACCES 0.0.0.0:80
I know already, that the Error EACCES means that i don't have access rights to the port 80, but i don't know how to fix this. Any help much appreciated!

If you need to run the server on port 80 you should use a reverse proxy like nginx that will run using a system account on a privileged port and proxy the requests to your Node.js server running on an unprivileged port (> 1024).
When running in development environment you're pretty much free to run as root (ie. sudo node server.js
), but that is rather dangerous in production environment.
Here's a sample nginx config that will see if the request is for a file that exists in the filesystem, and if not, proxy the request to your Node.js server running on port 9000
upstream yournodeapp {
server localhost:9000 fail_timeout=0;
keepalive 60;
}
server {
server_name localhost;
listen 80 default_server;
# Serve static assets from this folder
root /home/user/project/public;
location / {
try_files $uri @yournodeapp;
}
location @yournodeapp {
proxy_pass http://yournodeapp;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
Solution 2 - Javascript
to give root access to node and start server on port 80 you can do
sudo node app.js
this will start the server giving permission on port 80
Solution 3 - Javascript
Foremost, do not run as root. That's asking for 'it'. "It" is really bad. Go see the movie. Then, don't run your node web project as root.
// DO NOT DO THIS!
$ sudo node app.js
// DO NOT DO THIS EITHER!
$ sudo su -
# node app.js
Instead, use PM2 and authbind to do this:
// %user% is whatever user is running your code
sudo touch /etc/authbind/byport/80
sudo chown %user% /etc/authbind/byport/80
sudo chmod 755 /etc/authbind/byport/80
Next, add this alias to your ~/.bash_aliases
or ~/.bashrc
or ~/.bash_profile
:
alias pm2='authbind --deep pm2'
Then, try it with pm2:
pm2 start app.js

On Windows I fixed this by setting Express to listen on port 8080 for HTTP and 8443 for HTTPS. It really doesn't like using those lower number ports. Also I have IIS installed and running so it might be some sort of port conflict there too.
Solution 5 - Javascript
there is
sudo ufw allow 80/tcp
and it should be port forwarded, worked for me atleast
