我是node.js和MySQL初学者,我刚开始设置并尝试一些基本代码.但是,由于某种原因,我甚至无法与服务器建立简单的连接.我使用默认设置安装最新的MySQL Community 8.0数据库和Node.JS.

这是我的node.js代码

    var mysql = require('mysql');

    var con = mysql.createConnection({
      host: "localhost",
      user: "root",
      password: "password",
      insecureAuth : true
    });

    con.connect(function(err) {
      if (err) throw err;
      console.log("Connected!");
    });

以下是命令提示符中发现的错误:

C:\Users\mysql-test>node app.js
    C:\Users\mysql-test\node_modules\mysql\lib\protocol\Parse
    r.js:80
            throw err; // Rethrow non-MySQL errors
            ^

如何从MySQL命令行客户端更改rootMySQL用户的密码null- 意味着没有密码或''- ？

我已经设置了一个MySQL数据库.当我尝试通过我的Node JS服务器访问它时,我收到错误

"ER_NOT_SUPPORTED_AUTH_MODE:客户端不支持服务器请求的身份验证协议;请考虑升级MariaDB客户端"

这很奇怪,因为我已经卸载了MariaDB并使用Homebrew安装了MySQL.

这是我的连接尝试:

var mysql = require('mysql');

var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'root',
  password : '********',
  database : 'vod_bill_database'
}); 

有任何想法吗？谢谢

我有一个Node.js程序,它使用root帐户连接到本地MySQL数据库(这不是生产设置).这是创建连接的代码:

const mysql = require('mysql');

const dbConn = mysql.createConnection({
    host: 'localhost',
    port: 3306,
    user: 'root',
    password: 'myRootPassword',
    database: 'decldb'
});

dbConn.connect(err => {
    if (err) throw err;
    console.log('Connected!');
});

它适用于MySQL 5.7,但自从安装MySQL 8.0后,我在启动Node.js应用程序时遇到此错误:

> node .\api-server\main.js
[2018-05-16T13:53:53.153Z] Server launched on port 3000!
