javascript - Mysql JavaScript错误: ECONNREFUSED

Question

所以我正在尝试编写一个discord.js 机器人!我应该将discord bot 记录在 channel 中发送到mysql 的所有消息。我在互联网上搜索过，但没有找到解决我的问题的方法。 前任。 node.js mysql error: ECONNREFUSED

但是当我尝试连接到 mysql 时遇到了这个错误:

Error: connect ECONNREFUSED 127.0.0.1:3306
    at Object._errnoException (util.js:1022:11)
    at _exceptionWithHostPort (util.js:1044:20)

    at Function.Module._load (module.js:491:3)
    at Function.Module.runMain (module.js:684:10)

这是我的代码:

const Discord = require("discord.js");
const client = new Discord.Client();
const fs = require("fs");
const config = require("./config.json");
const mysql = require('mysql');

var con = mysql.createConnection({
  port: '3306',
  host: config.host,
  user: config.user,
  password: config.password,
  database: config.database
});

con.connect(err => {
    if(err) throw err;
    console.log('Mysql connected')
});

console.log(config.StartupMessage)

client.on("message", message => {
  if(message.author.bot) return;

  if(message.channel.id == config.LogChannelId)  {
  var Attachment = (message.attachments).array()
  var sql = "INSERT INTO " + config.Table + " (" + config.ColumnName + ", " + config.ColumnMessage + ", " + config.ComumnAttachment + ") VALUES (" + message.author.tag + ", " + message + ", " + message.attachments + ")"
   con.query(sql, function (err, result) {
      if (err) return console.log(err);
      console.log("1 record inserted");
    })
    console.log(sql)
  };
});
client.login(config.token); 

更新

config.json 文件:

{
"token":"bot token",
"LogChannelId":"405382594645983233",
"StartupMessage":"Bot has started",

"host":"localhost",
"user":"root",
"password":"password",
"database":"PinkCraft",

"Table":"log",
"ColumnName":"Name",
"ColumnMessage":"Message",
"ColumnId":"id",
"ComumnAttachment":"attachment"
}

我正在使用service mysql start来启动mysql。

这是我的错...... 问题是我通过 Visual Studio Code 通过 samba 运行节点到我的 rpi。当我直接从 pi 运行节点时，它起作用了!
