Question

我使用在新vpc（Amazon Linux）上部署的ssh隧道设置了mongo数据库，我按照此处的说明进行操作：

https://docs.aws.amazon.com/quickstart/latest/mongodb/step2.html

我能够通过PuTTY，Mongo Compass和Robo3T连接到我的数据库，但是我找不到通过Node JS连接到我的数据库的方法。我尝试使用“ tunnel-ssh”包，但仍无法连接到数据库。我收到此错误：

AssertionError [ERR_ASSERTION]: null == { MongoNetworkError: failed to connect to server [PrimaryReplicaNode0-PrivateIPs:27017] on first connect [MongoNetworkError: connect ETIMEDOUT 10...

这是我的代码：

import { MongoClient, ObjectID } from 'mongodb';
import { format } from 'util';
import tunnel from 'tunnel-ssh';
import assert from 'assert';

const user = encodeURIComponent('username');
const password = encodeURIComponent('password');
const authMechanism = 'SCRAM-SHA-1';
const url = format('mongodb://%s:%s@PrimaryReplicaNode0-PrivateIPs:27017/?authMechanism=%s&authSource=admin&ssl=false', user, password, authMechanism);

const sshConfig = {
  usesrname: 'ec2-user',
  host: 'LinuxBastion-PublicDNS(IPv4)',
  port: 22,
  dstHost: 'PrimaryReplicaNode0-PrivateIPs',
  dstPort: 27017,
  privateKey:require('fs').readFileSync('ssh/key-pair.pem'),
  localHost:'127.0.0.1',
  localPort: 3000
};
var tnl = tunnel (sshConfig, (error, server) => {
    if (error){
        console.log("SSH connection error: " + error);
    } 

    MongoClient.connect(url, { useNewUrlParser: true }, (err, client) => {
       assert.equal(null, err);
       console.log("Connected correctly to server!");
       tnl.close();
    }
}

我在Google上搜索了整整一周，但是一切仍然是负面的，因此任何人都对此有经验，请帮帮我一下。

谢谢。
