续集。连接mysql时出错。 “用户'someuser'@'localhost'的访问被拒绝（使用密码：NO）”

Question

我按照这些说明安装并配置了 mysql。 此外，我将

bind-address

文件中的

127.0.0.1

从

0.0.0.0

更改为

/etc/mysql/mysql.conf.d/mysqld.cnf

，以便能够通过 workbrench 从我的电脑进行连接。这是我的均衡代码：

import { Sequelize, DataTypes } from "sequelize";
import { logger } from "../utils/index.js";

const sequelize = new Sequelize({
  host: process.env.DB_HOST,
  port: process.env.DB_PORT,
  database: process.env.DB_NAME,
  username: process.env.DB_USER,
  password: process.env.DB_PASS,
  dialect: "mysql",
  logging: (msg) => logger(msg, "database"),
});

sequelize.authenticate().then(() => {
  console.log('Connection has been established successfully.');
}).catch((error) => {
  console.error('Unable to connect to the database: ', error);
});

.env:

DB_HOST=localhost
DB_USER=someuser
DP_PASS=Somepassword@
DB_PORT=3306
DB_NAME=dbname

npm run启动后的错误日志：

我在与数据库相同的计算机上运行应用程序。

通过 MYSQL Workbrench 我连接没有任何问题。

Nodejs 包：

sequelize 6.33.0

、

mysql2 3.6.2

Mysql版本：

mysql Ver 8.0.35-0ubuntu0.23.04.1 for Linux on x86_64 ((Ubuntu))
