Node.js는 mysql 데이터베이스에 연결하는 방법을 구현합니다.

npm install node-mysql

var express = require('express');
var mysql = require('mysql');
var app = express();
app.use(function(req, res, next){
 console.log('%s %s', req.method, req.url);
 next();
});
var conn = mysql.createConnection({
  host:'localhost',
  user:'root',
  database:'ceshi',
  password:'123456',
  port:3306
});
conn.connect();
app.get('/', function(req, res){
  conn.query('SELECT * from ceshibiao', function(err, rows, fields) {
    if(err) throw err;
    var data = '';
    foreach(rows,function(key,value){
      data += &#39;<p>&#39; + &#39;contents：&#39; + value.contents + &#39;</p>&#39;;
      data += &#39;<hr />&#39;;
    }
    res.send(data);
  });
});
app.listen(81);
console.log(&#39;Listening on port 81&#39;);
