nodejs访问远程数据库失败，用dbeaver是能连接到这个数据库的
代码块功能
const dns = require('dns');
let HOSTA = ''
//一开始用的resolve 后来改成了lookup
//dns.resolve('www.liuyue.fun', (err, records) => {
// HOSTA = records[0]
dns.lookup('www.baidu.com', (err, address, family) => {
console.log('records', address)
HOSTA = address
if (err) {
console.error('--域名解析失败' + err)
}
console.log('HOSTA', HOSTA)
});
这里解析出的ip是 110.242.68.3(我以百度举例，实际上我是用家里电脑的域名解析出来的公网ip)
接下来创建服务器连接：
const mysql = require('mysql');
// 创建连接池
const pool = mysql.createPool({
host: HOSTA,
port: 3366, //家里数据库设置的端口是3366
user: 'root', //用户名
password: 'password', // 密码
database: 'database_name', // 数据库名字
connectionLimit: 10
})
运行结果及报错内容
结果报错了，我看报错里的地址是127.0.0.1，这还是本地的地址，但是我Host不是写了上边域名解析过的公网Ip了嘛？

我（前端）是在另一个地方开发，想连接到家里的数据库。用了以上方法行不通，查了好久“nodejs 连接远程数据库”之类的，都查不到结果。请教大家！！！TAT！！！
