Getting Started with MongoDB on Linux: Setting up Your Environment

MongoDB is a popular NoSQL database that offers high scalability and flexibility, making it a great choice for modern applications. In this post, we’ll walk you through the process of setting up a MongoDB environment on a Linux system.


  • A Linux-based operating system (e.g. Ubuntu, CentOS, Debian)
  • Administrative access to your system
  • An active internet connection

Step 1: Install MongoDB

The first step to getting started with MongoDB is to install it on your Linux system. The installation process varies depending on your Linux distribution, so be sure to check the MongoDB documentation for your specific distribution.

For example, on Ubuntu, you can install MongoDB by running the following command:

sudo apt install mongodb

This will install the latest stable version of MongoDB available in the Ubuntu repositories. Once the installation is complete, you can start the MongoDB service by running:

sudo systemctl start mongodb

You can verify that MongoDB is running by checking the service status:

sudo systemctl status mongodb

Step 2: Connect to MongoDB

To interact with MongoDB, you’ll need to connect to the MongoDB server. By default, MongoDB listens on port 27017. You can connect to MongoDB using the mongo shell by running the following command:


This will open the MongoDB shell, where you can interact with the MongoDB server.

Step 3: Create a Database

Now that you’ve connected to MongoDB, you can create your first database. To create a new database, use the use command:

use mydatabase

This will create a new database called mydatabase. You can switch to this database by running:

use mydatabase

Step 4: Create a Collection

Collections in MongoDB are similar to tables in relational databases. To create a new collection in your database, use the db.createCollection() command:


This will create a new collection called mycollection in your mydatabase.

Step 5: Insert Data

Now that you have a database and a collection, you can insert data into it. To insert a new document, use the insertOne() method:

db.mycollection.insertOne({ name: "John", age: 30 })

This will insert a new document with the fields name and age into the mycollection collection.

Step 6: Query Data

To query data from MongoDB, you can use the find() method. For example, to find all documents in the mycollection collection, run:


This will return all documents in the mycollection collection.


In this post, we’ve covered the basics of setting up a MongoDB environment on a Linux system. We’ve walked through the installation process, connecting to MongoDB, creating a database and collection, inserting data, and querying data. In the next post, we’ll dive deeper into MongoDB’s document model and how to work with data in MongoDB. Stay tuned!
