我在AWS EC2 Linux机器上运行MongoDB服务器v6.0.4，它是公共可访问的。

• 使用MongoDB：6.0.4使用Mongosh：1.8.0版 *

/etc/监视配置文件

# network interfaces
net:
  port: 27017
  ipv6: true
  bindIp: ::,0.0.0.0  # Tried with public DNS and IP as well here.

security:
  authorization: enabled
  keyFile: /etc/mongodkeyfile.key

#operationProfiling:

replication:
  replSetName: rs0

能够通过mongosh在同一台计算机上连接来执行所有DB操作，
当我从Mac机器ping时，EC2机器响应。

而当我尝试通过Nodejs应用程序连接时，出现以下错误

MongoServerSelectionError: getaddrinfo ENOTFOUND ip-xx-x-xx-xxx.ap-south-1.compute.internal
at Timeout._onTimeout (/Users/durgalovababupadala/myprojects/continuum-electrolite/ev-server/node_modules/mongodb/lib/sdam/topology.js:293:38)
at listOnTimeout (node:internal/timers:569:17)
at process.processTimers (node:internal/timers:512:7)

这是我的示例代码，

const { MongoClient } = require("mongodb");

// Replace the uri string with your connection string.
const uri = "mongodb://<user>:<pwd>@<EC2-PublicIP>:27017/<dbname>?replicaSet=rs0&useUnifiedTopology=true";

const client = new MongoClient(uri);

async function run() {
  try {
    const database = client.db('test');
    console.log(database);
    const myColl = database.collection("pizzas");
    const doc = { name: "Neapolitan pizza", shape: "round" };
    const result = await myColl.insertOne(doc);
    console.log(
      `A document was inserted with the _id: ${result.insertedId}`,
    );

  } finally {
    // Ensures that the client will close when you finish/error
    await client.close();
  }
}
run().catch(console.dir);

先谢谢你，

**更新：**在同一台EC2机器上使用MongoDB连接执行简单节点应用程序，并且运行正常。
