Question

因此，我关注了以下视频：https://www.youtube.com/watch?v=XuLRKMqozwA

我的代码如下：

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

我在文件所在的目录中键入了npm install mysql。

然后键入node new new 是文件名。

我收到的错误完全如下：

events.js:174
      throw er; // Unhandled 'error' event
      ^

Error: connect ECONNREFUSED 127.0.0.1:3306

我能找到的所有其他“解决方案”对我都没有用。我做错了很简单，因为我显然没有很多经验。任何事情都会有所帮助。

错误：连接ECONNREFUSED 127.0.0.1:3306
