Mongo Database Installation on Ubuntu and Common Initial Configuration


MongoDB is a popular NoSQL database that is known for its flexibility and scalability. In this blog post, we will guide you through the process of installing MongoDB on Ubuntu and provide some common initial configuration steps to get you started.

Step 1: Update System Packages

Before installing MongoDB, it is always a good idea to update the system packages to their latest versions. Open the terminal and run the following commands:

sudo apt update
sudo apt upgrade

Step 2: Import the MongoDB GPG Key

Next, we need to import the MongoDB GPG key to ensure the authenticity of the package. Run the following command in the terminal:

wget -qO - | sudo apt-key add -

Step 3: Add the MongoDB Repository

To install the latest version of MongoDB, we need to add the MongoDB repository to our system. Run the following command in the terminal:

echo "deb [ arch=amd64,arm64 ] $(lsb_release -sc)/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

Step 4: Install MongoDB

Now that we have added the repository, we can proceed with the installation of MongoDB. Run the following command in the terminal:

sudo apt update
sudo apt install mongodb-org

Step 5: Start and Enable MongoDB

After the installation is complete, we need to start and enable the MongoDB service. Run the following commands:

sudo systemctl start mongod
sudo systemctl enable mongod

Step 6: Verify MongoDB Installation

To verify that MongoDB is installed and running correctly, run the following command in the terminal:

mongo --version

You should see the version number of MongoDB displayed on the screen.

Common Initial Configuration

Now that MongoDB is installed, there are a few common initial configuration steps that you may want to consider.

1. Securing MongoDB

By default, MongoDB does not require authentication, which means anyone with access to the server can access the database. It is highly recommended to enable authentication to secure your MongoDB installation. You can follow the official MongoDB documentation to learn more about enabling authentication.

2. Configuring Firewall

To enhance the security of your MongoDB installation, you can configure the firewall to allow only specific IP addresses or ranges to access the database. This will help prevent unauthorized access to your data. Refer to your operating system’s documentation for instructions on configuring the firewall.

3. Creating Database Users

To manage access to your MongoDB databases, you can create database users with different roles and privileges. This allows you to control who can read, write, or modify data in your databases. Refer to the MongoDB documentation for instructions on creating and managing database users.

4. Monitoring and Performance Optimization

MongoDB provides various tools and features for monitoring and optimizing the performance of your database. You can use tools like MongoDB Compass or MongoDB Cloud to monitor the health of your database, analyze query performance, and make necessary optimizations.


Installing MongoDB on Ubuntu is a straightforward process, and with a few initial configuration steps, you can ensure the security and performance of your database. By following the steps outlined in this blog post, you can get started with MongoDB and leverage its power and flexibility for your applications.
