How to connect to a mongodb database remotely

We have already introduced some basic knowledge of "MongoDB". Today we will learn how to connect to the MongoDB database remotely. To connect to the MongoDB database remotely, we can follow the steps below:

1. Ensure that the MongoDB database has been installed and the mongod service has been started.
2. On the MongoDB server, open the/etc/mongod.conf file and edit it to allow remote connections. Add 0.0.0.0 to the bindIp field to allow all IPs to access the database. For example: bindIp: 0.0.0.0
3. Assign an account to the MongoDB user and grant the required permissions.
4. On the client computer, use the MongoDB client (such as the mongo shell or other third-party applications) to connect to the MongoDB database. An example command is as follows:

 mongo --host < hostname > --port < port > -u < username > -p < password > --authenticationDatabase < auth_database >

Where,<hostname>is the host name or IP address of the MongoDB server,<port>is the port of the MongoDB server (the default port is 27017),<username>and<password>are the credentials of the MongoDB user, and<auth_database>is the database name to verify the user credentials.

5. After the connection is successful, you can use the corresponding command to manage the MongoDB database.

It should be noted that there are certain security risks in connecting MongoDB databases remotely, so you must ensure that appropriate security measures are taken during the connection process. For example, use SSL to encrypt connections, enable authentication, and so on.
