Prerequiste

I assume that you have a Centos installation.

Installation

You can copy/paste this script and use it to configure automatically your server.

#!/bin/bash
 
echo "install prerequistes"
dnf -y install nodejs
 
echo "create working directory"
mkdir -p /var/www/nodejs
 
echo "create nodejs server"
cat > /var/www/nodejs/server.js << "EOF"
var http = require('http');
 
 
var server = http.createServer(function(req, res) {
 
  res.writeHead(200);
 
  res.end('Hello World !!');
 
});
 
server.listen(4587);
 
EOF
 
 
echo "create service"
cat > /etc/systemd/system/myNodeJsService.service << "EOF"
