无法连接到Node.js上的MySQL数据库

问题描述

我仍然无法弄清楚为什么我在尝试连接到Node.js上的MYSQL Server时仍然收到此错误消息-

I still cannot figure out why Im still getting this error message when trying to connect to the MYSQL Server on Node.js -

错误-

Error: ER_ACCESS_DENIED_ERROR: Access denied for user 'root'@'localhost' (using password: YES)

JS-

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

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

推荐答案

node.js中没有问题

There is no prolem in your node.js

node.js只需要安装mysql

node.js require only mysql installation

->在命令提示符下转到nodejs的安装，然后输入

-> go to installation of nodejs in the command prompt and enter

 npm install mysql

在Eclipse中: 1)安装nodejs插件 2)在nodejs项目中打开package.json并输入

in Eclipse: 1) install the nodejs plugin 2) open package.json in the nodejs project and enter

       "author": "Krish",
       "dependencies": {
                "mysql": "2.x.x"
      },

3) right click on the project run -> node install

它将安装mysql并准备连接数据库

it will install the mysql and you are ready to connect the Database

ER_ACCESS_DENIED_ERROR

ER_ACCESS_DENIED_ERROR

1)转到mysql命令提示符

1) go to mysql command prompt

   mysql> create user 'root'@localhost IDENTIFIED BY 'password';

2)授予权限

   mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT
        OPTION;

或

   mysql>SHOW GRANTS FOR 'root'@'localhost';

现在您可以运行JS了.它会被宽恕

now you can run you JS . it will be conneced
