Preface

MongoDB is a free and open-source No-SQL document database. It’s extensively used in web applications and NLP. By default MongoDB connects to localhost (127.0.0.1). Therefore we can access all databases and its services on the same computer where it is installed. But there are times when we require to connect MongoDB to a remote location.

Environment Setup

We have two computers. Both of these are connected to a local network. System one will be our server ( IP: 192.168.1.11 ). It uses Ubuntu OS and MongoDB resides here.

Step 1- Install MongoDB

To install any packages in Debian based OS, “apt-get” command is used. Therefore to install MongoDB in ubuntu we use:

Step 3-Firewall and MongoDB settings

By default, other machines can not access MongoDB which is running on system one ( 192.168.1.11 ). Therefore, to make it accessible to other machines, there are two important steps to make MongoDB accessible to the local network. First. Open the firewall and IP address entry. Both of these settings are done on the server-side ( 192.168.1.11 ).

Step 4-Client-side access check

On the client-side, install robo3t or we can use pymongo to access the database. Open robo3t, go to File->Connect and we shall get:

What is MongoDB authorization?

MongoDB Authorization grants access to data and commands through role-based authorization. In MongoDB Authorization, Privilege is either specified explicitly in the role or inherited from another role, or both. MongoDB allows us to create new user roles for particular databases if we think that the existing built-in roles to control access to a MongoDB system do not describe the set of desired privileges. In addition, you can also create Superuser roles that provide either direct or indirect system-wide superuser access.

What is the primary key in MongoDB?

In addition, for every collection, MongoDB reserves a field called _id, also known as the id field. This field is the primary key for any collection and uniquely identifies a document within any collection. When you insert a document in a collection and don’t specify an _id, MongoDB will fill that in for you with Mongo ObjectId value. Alternatively, you can specify custom primary keys with one or more values of your choice.

What is a MongoDB replica set?

Replica sets: A replica set is when MongoDB creates copies of the data and stores them in other servers. This feature provides a safety net in case that the main server of a MongoDB database fails or when maintenance takes place; it switches to the other server to serve the data for the end users. This is a seamless operation; by default in the free tier of MongoDB Atlas, a replica set of 3 servers is automatically configured.
