您正在与用户Root连接,我相信它是root。您的错误显然是凭据错误。

错误:ER_ACCESS_DENIED_ERROR(错误访问被拒绝错误):都是因为得到了允许。
据我所知,你的上述代码,你需要改变根到根

var mysql = require('mysql');

var con = mysql.createConnection({
   host     : 'localhost',
  user     : 'root',
  password : 'my_pass',
});

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

我遇到过一个类似的问题,我可以使用CLI以相同的凭据登录,但不能使用nodejs(mysql-server 8.0)中的mysql2。通过使用%代替localhost解决了这个问题:

CREATE USER 'user'@'%' IDENTIFIED WITH mysql_native_password BY 'password';
GRANT ALL PRIVILEGES ON db.* TO 'user'@'%';

而不是

CREATE USER 'user'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
GRANT ALL PRIVILEGES ON db.* TO 'user'@'localhost';
