How to Install MongoDB Community Edition on Ubuntu 24.04 Noble Numbat

MongoDB is a popular NoSQL database known for its high performance, scalability, and flexibility. This guide will walk you through the steps to install MongoDB Community Edition on Ubuntu 24.04 Noble Numbat.

Step 1: Import the MongoDB GPG Key

The first step in installing MongoDB is to import the public GPG key used by the package management system to verify the packages. Open your terminal and run the following command:

$ wget -qO - https://www.mongodb.org/static/pgp/server-6.0.asc | sudo apt-key add -

Step 2: Create the MongoDB Source List

Next, create a list file for MongoDB. Use the following command to create the file and add the MongoDB repository:

$ echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/6.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-6.0.list

Step 3: Update the Package Database

After adding the MongoDB repository, update the local package database:

$ sudo apt update

Step 4: Install MongoDB Packages

Now, install the MongoDB packages. This command will install mongodb-org, which includes the latest stable version of MongoDB along with related tools:

$ sudo apt install -y mongodb-org

Step 5: Start and Enable MongoDB Service

Once the installation is complete, start the MongoDB service and enable it to start on boot:

$ sudo systemctl start mongod
$ sudo systemctl enable mongod

To check the status of the MongoDB service, use the following command:

$ sudo systemctl status mongod

You should see output indicating that MongoDB is active and running.

Step 6: Verify the Installation

To verify that MongoDB was installed and is running correctly, you can connect to the MongoDB shell using the mongo command:

$ mongo --eval 'db.runCommand({ connectionStatus: 1 })'

If MongoDB is running properly, you will see output showing the connection status.

Step 7: Configure MongoDB (Optional)

MongoDB Configuration File

The MongoDB configuration file is located at /etc/mongod.conf. You can edit this file to change the default configuration settings. For example, to change the bind IP address to allow remote connections, you can modify the bindIp setting:

$ sudo nano /etc/mongod.conf

Find the net section and update the bindIp value:

net:
  port: 27017
  bindIp: 0.0.0.0

Save the file and exit. Then, restart the MongoDB service to apply the changes:

$ sudo systemctl restart mongod

Create an Administrative User

To secure your MongoDB installation, it is recommended to create an administrative user. First, connect to the MongoDB shell:

$ mongo

Switch to the admin database:

use admin

Create a new administrative user with a username and password of your choice:

db.createUser({
  user: "admin",
  pwd: "yourpassword",
  roles: [{ role: "userAdminAnyDatabase", db: "admin" }]
})

Exit the MongoDB shell:

exit

Enable Authentication

To enable authentication, edit the MongoDB configuration file again:

$ sudo nano /etc/mongod.conf

Find the security section and enable authorization:

security:
  authorization: "enabled"

Save the file and exit. Then, restart the MongoDB service:

$ sudo systemctl restart mongod

Now, you need to authenticate as the administrative user to perform any actions in the MongoDB shell:

$ mongo -u admin -p --authenticationDatabase admin

Conclusion

You have successfully installed MongoDB Community Edition on your Ubuntu 24.04 Noble Numbat system. You can now start using MongoDB to manage your databases and applications.
