参考代码

 /**
  * 测试mysql连接
  */

 var mysql = require('mysql');
 var connection = mysql.createConnection({
   host     : 'localhost',  //服务器
   user     : 'root', //用户名
   password : 'root', //密码
   database : 'mysql' //数据库
 });
 connection.connect(function(err) {
     if(err) {
         console.error('error connecting: ' + err.stack);
         return;
     }
     console.log('connected as id ' + connection.threadId);
 });

 var http = require('http');

 var server = http.createServer(function(request, response){
     response.writeHeader(200, {'Content-type': 'text/html'});
     // 查询User为root的用户
     connection.query('SELECT * FROM user WHERE User = ?', ['root'], function(err, results, fields){
         if(err) {
             throw err;
         }
         var data = '';
         for (var i = 0; i < results.length; i++) {
             var firstResult = results[i];
             data += 'User: '+ firstResult['User'] + '&nbsp;&nbsp;Password: ' + firstResult['Password'] + '<br>';
         }

         response.write(data);
         response.end();

     });
 });

 server.listen(8080);

 var sys = require('util');
 sys.puts('Server running at http://localhost:8080/');
