我有类似这个人的问题:连接ECONNREFUSED - 节点js,sql

我正在尝试将app.js连接到作为MAMP一部分运行的现有数据库.MAMP在端口8889上运行mysql; 我怎么告诉node.js哪个端口找到mysql？

我一直SequelizeConnectionRefusedError试图连接到我的服务器上的MySQL数据库.

登录凭据是正确的,端口是打开的,一切看起来都很好(并且在开发环境中就像一个魅力).

对于稀缺的背景信息感到抱歉,但我在这里傻眼了 - 我真的不知道是什么原因导致了这个问题.

这是我的输出 mysql --version

mysql  Ver 14.14 Distrib 5.5.43, for debian-linux-gnu (x86_64) using readline 6.3

这是我用来初始化Sequelize的代码.我想要它使用的表还不存在,但我很确定这个问题没有任何关系.我已尝试使用root用户登录,但没有骰子 - 我仍然得到相同的错误.

var sequelize = new Sequelize("database", username, password, {
    host: "localhost",
    dialect: "mysql",
    port: 3306,
    define: {
        paranoid: true
    }
});

var Model = sequelize.define("Model", {
    md5: {type: Sequelize.STRING(128)},
    ip: {type: Sequelize.STRING(256)},
    url: {type: Sequelize.STRING(1024)}
});

sequelize.sync();

这是在Ubuntu 14.04上运行的,其中节点在Passenger后面运行(尽管如果我直接运行带有节点的应用程序也会出现错误).我在同一台服务器上运行nginx和PHP,其中另一个PHP应用程序连接到数据库,如果有任何相关性的话.

什么可能导致这个问题？

我无法运行服务器......我收到错误消息 ECONNREFUSED

如何解决此错误！

当我尝试使用不同的端口时......都给了我同样的错误！

我正在运行这个脚本:

var mysql      = require('mysql');

var connection = mysql.createConnection("mysql://localhost/");

connection.connect();
console.log(connection)

但是得到错误......

   { host: 'localhost',
     port: 3306,

我无法连接到 MySQL 数据库。我在谷歌上搜索了一些解决方案，但似乎没有一个有效，或者我可能还没有理解它们。这是设置：

let express = require("express");
let mysql      = require("mysql");
let http = require("http");

let app  = express();
http.createServer(app).listen(8000, function() {
    console.log("Listening on http://localhost:" + port)
});

var connection = mysql.createConnection({
    host: "127.0.0.1",
    user: "root",
    password: process.env.DB_PASSWORD,
    database: "users",
    port: 8000
});

connection.connect();

connection.query("SELECT * FROM user", function(err, rows, fields)
{
    if (err) {
        console.error("error connecting: " + err.stack);
        return;
    }

    console.log(rows[0]);
});

connection.end();

尝试与“socketPath”和另一个端口建立连接，但它们都返回错误：
