无法在opsworks AWS中使用Node.js和MySql连接

Question

我试图在aws

中的opsworks中连接两个图层

1. 节点js app服务器。
2. Mysql图层

我创建了一个node.js应用程序并部署在AWS mysql连接详细信息代码中的s3存储库中，格式如下

exports.db = {"adapter":"mysql",

          "database":"DBname",

          "password":"xyz",

          "port":3306,

          "reconnect":true,

          "username":"root",

          "data_source_provider":"rds",

          "host":"localhost"

         }

exports.memcached = {"port":11211,

                 "host":null}

连接的实际代码是......

var express = require('express');

var app = express();

var mysql=require('./shared/config/opsworks.js');

app.get('/', function(req, res) 
{

 var connection = mysql.exports.db;

    connection.connect();

    connection.query('CREATE TABLE SAMPLE(PK_ID INT NOT NULL AUTO_INCREMENT,USERNAME VARCHAR(100) NOT NULL, PRIMARY KEY ( PK_ID )); ',

    function(err, rows, fields) {

    connection.end();

    res.writeHead(200,{'Content-Type':'text/plain'});

          if (!err)

           {

          res.write('TABLE CREATED SUCCESSFULLY');

          console.log('TABLE CREATED SUCCESSFULLY');

          }
         else
         {
              res.write('ERROR');
              console.log(err);
         }

       });

        res.write('OUTSIDE QUERY');

    res.end();

});

app.use(express.static('public'));

app.listen(80);

console.log('Listening on port 80');

当我点击公共IP时，代码无效，任何人都可以帮我纠正代码
