Question

我是node.js的新手，并试图学习它。
我已经安装了node-mysql NPM模块。这里我列出了访问mysql的代码：

// Include http module, 
var http = require('http'), 
// And mysql module you've just installed. 
   mysql = require("mysql"); 

// Create the connection. 
// Data is default to new mysql installation and should be changed according to your configuration. 
var connection = mysql.createConnection({ 
   user: "root", 
   password: "", 
   database: "astitvabmt",
   host: '127.0.0.1',
   port: '3306',
   _socket: '/var/run/mysqld/mysqld.sock'
}); 

// Create the http server. 
http.createServer(function (req, res) {
   // Attach listener on end event. 

      // Query the database. 
      connection.query('SELECT * FROM tbluser;',function(err, results, fields) {
                if (err) throw err;
                console.log("sachin : " + results);
                var output = '<html><head></head><body><h1>Latest Posts</h1><ul><table border=1><tr>';
                for (var index in fields) {
                    output += '<td>' + fields[index].name + '</td>';
                }
                output += '</tr>';
                for (var index in results) {
                    output += '<tr><td>' + results[index].Recipe + '</td>';
                    output += '<td>' + results[index].Amount + '</td>';
                    output += '<td>' + results[index].Unit + '</td>';
                    output += '<td>' + results[index].Ingredient + '</td></tr>';
                }
                output += '</ul></body></html>';
                res.writeHead(200, {'Content-Type': 'text/html'});
                res.end(output);
            });                       

// Listen on the 8080 port. 
}).listen(8080);
console.log('Server mysqlJS running at 8080');

但我得到的错误是：

sachin@ubuntu:/opt/lampp/htdocs/1nodeapp$ node mysql.js
Server mysqlJS running at 8080

Error: connect ECONNREFUSED

我的mysql配置中没有跳过网络选项。
我已经在我的PC上安装了XAMPP。以前我使用3306端口进行mysql连接，使用apache。
