Node.js Mysql：连接失败

我正在尝试将node.js连接到mysql，但失败了，我已经安装了mysql。谁能帮我吗？

const express    = require("express");
const mysql      = require('mysql');

var app = express();

var mysqlConnection = mysql.createConnection({
    host: "localhost",
    user: "root",
    password: "******",
    database: "otablo",
});

mysqlConnection.connect((err)=> {
    if(!err)
    {
        console.log("Connected");
    }
    else
    {
        console.log("Connection Failed");
    }
})
