Connecting to a remote mongoDB server

问题

I have a remote machine which I connect to using SSH, I installed mongoDB on it, and I wish to use it remotely, how do I connect to it using nodejs and mongoDB compass? the localhost is the IP ?

const db = "mongodb://what do I write here?";
const connectDB = async () => {
  try {
    await mongoose.connect(db, { useNewUrlParser: true, useCreateIndex: true });
    console.log("MongoDB Connected...");
  } catch (err) {
    console.error(err.message);
    process.exit(1);
  }
};
connectDB();

Short answer

Login to your machine, open mongodb configuration file located at /etc/mongod.conf and change the bindIp field to your machine ip address (it is the same ip address which you are using to ssh to your machine), after that restart mongodb server.

Detailed answer

Open /etc/mongod.conf file using any of the editor, if you are running a desktop version then you can make use of gedit utility tool
```
  sudo gedit /etc/mongod.conf
```

If you are running a server version, then you can make use of vi editor command

    sudo vi /etc/mongod.conf

The file should contain the following kind of content:

  systemLog:
      destination: file
      path: "/var/log/mongodb/mongod.log"
      logAppend: true
  storage:
      journal:
          enabled: true
  processManagement:
      fork: true
  net:
      bindIp: 127.0.0.1  // enter your ip address here
      port: 27017
  setParameter:
      enableLocalhostAuthBypass: false

Once you change the bindIp, then you have to restart the mongodb, using the following command
```
  sudo service mongod restart
```
Now you'll be able to connect to the mongodb server, with the same ip address which you are using to ssh to your system.
```
  mongoose.connect('mongodb://<machine_ip_address>:27017/<database_name>')
```

回答2:

mongoose.connect('mongodb://username:password@host:port/database')

Now for the host, is there any hostname or IP you could use?

回答3:

Try this one:

mongoose.connect("mongodb://localhost/<database-name>", { useNewUrlParser: true });
const db = mongoose.connection
db.on('error', (error) => console.error(error));
db.once('open', () => console.log('Connected to Database'));

Make sure to run MongoDB

mongod --config /usr/local/etc/mongod.conf

回答4:

first try this : mongoose.connect('mongodb://localhost:27017/database')

mongoose.connect('mongodb://<machine_ip_address>:27017/<database_name>')

mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[database][?options]]
