Having structured data simplifies lookup and maintenance compared to unstructured data. MongoDB is a NoSQL document database platform designed to overcome the limitations of traditional relational databases and other NoSQL solutions.
It employs a flexible schema for data storage, allowing updates and alterations at any time, unlike relational databases. MongoDB supports multiple operating systems, including the latest Ubuntu 24.04. This guide details the installation process.
How to Install MongoDB on Ubuntu 24.04
MongoDB excels with unstructured data and handles large volumes efficiently, making it suitable for Big Data systems, Map Reduce applications, news site forums, and social networking applications.
On Ubuntu 24.04, the most reliable method to install MongoDB involves using its official repository.
Step 1: Add the MongoDB repository to your system’s sources list. This command configures the path for the GPG key and then saves the repository link to the sources list directory.
echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list
Step 2: Import the MongoDB public GPG key to verify the authenticity of the MongoDB packages.
curl -fsSL https://www.mongodb.org/static/pgp/server-7.0.asc | \
sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg \
--dearmor
Step 3: Update the apt packages list to include the MongoDB repository.
sudo apt update
Step 4: Install MongoDB using the apt package manager. This command installs the mongodb-org package, which includes the MongoDB server, shell, and related tools.
sudo apt install -y mongodb-org
To confirm the MongoDB installation, check the installed version by running the following command.
Step 5: Verify the MongoDB installation.
mongod --version
Alternative Installation Method
On the official MongoDB website, you can find .deb and .tar files available for download. These files can be downloaded by selecting the appropriate platform and package, or by copying the download link and using wget in the command line.
wget https://repo.mongodb.org/apt/ubuntu/dists/jammy/mongodb-org/7.0/multiverse/binary-arm64/mongodb-org-server_7.0.7_arm64.deb
Trying to install it this way may result in broken packages and dependency issues. Fixing these issues can be time-consuming, as the necessary dependencies might not have compatible release files.
echo "deb http://security.ubuntu.com/ubuntu impish-security main" | sudo tee /etc/apt/sources.list.d/impish-security.list
How to Configure MongoDB on Ubuntu 24.04
After installing MongoDB, configuration is necessary for smooth operation. MongoDB is often inactive after installation, so verify its service status.
Step 1: Check the status of the MongoDB service.
sudo systemctl status mongod
Step 2: Enable and start the MongoDB service. If the service is inactive, enable it to start on boot and then start it manually.
sudo systemctl enable mongod
sudo systemctl start mongod
Step 3: Launch the MongoDB shell. This command opens the mongosh interface, allowing you to interact with the MongoDB database.

By default, no user is added to the database, and no authentication is required. You can create an admin user to enhance security.
Step 4: Switch to the admin database.
use admin
Step 5: Create a new user with the necessary roles. Replace <desired-user-name> and <desired-password> with your desired credentials.
db.createUser(
{
user: "<desired-user-name>",
pwd: "<desired-password>",
roles: [ { role: "root", db: "admin" } ]
}
)
Step 6: Verify the user creation by listing MongoDB users.
show users
To secure the database, enable authentication and configure access for specified systems by setting their IP addresses and the default port (27017) in the MongoDB configuration file.
security:
authorization: enabled
net:
Port: 27017
bindIp: <give-IPaddress>
To allow communication between the MongoDB server and other systems, configure the firewall to allow traffic on port 27017.
Step 7: Allow port 27017 through the firewall.
sudo ufw allow 27017
Step 8: Restart the MongoDB service to apply the changes, and verify that the port is communicating successfully.
sudo systemctl restart mongod
sudo lsof -i | grep mongo
How to Remove MongoDB on Ubuntu 24.04
To completely remove MongoDB from Ubuntu 24.04, follow these steps.
Step 1: Uninstall MongoDB using the apt package manager. The --autoremove option removes any dependencies that are no longer needed.
sudo apt remove --autoremove mongodb-org
Step 2: Remove the MongoDB repository directory from the sources.list.d folder.
sudo rm /etc/apt/sources.list.d/mongodb-org-7.0.list
Step 3: Remove the GPG key added to the Ubuntu keyring directory.
sudo rm /usr/share/keyrings/mongodb-server-7.0.gpg
MongoDB is a NoSQL document database used for applications needing flexible schemas and large data volumes; installing via the official repository is the recommended method. After installation, configuring authentication and firewall settings enhances security.
