MongoDB is a NoSQL database that uses a document-oriented data model, making it ideal for handling large amounts of data. In this guide, we will walk through the steps to install and secure MongoDB on Debian 11.
Step 1: Update Your System
Start by ensuring your system is up to date:
sudo apt update && sudo apt upgrade -yStep 2: Import the MongoDB Public Key
Import the public GPG key used by the MongoDB package management system:
wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -Step 3: Create the MongoDB Source List File
Create a list file for MongoDB:
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/debian bullseye/mongodb-org/5.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.listStep 4: Update the Package Database

By default, MongoDB is not secured. To secure it, first, enable authentication. Edit the MongoDB configuration file:
sudo nano /etc/mongod.confFind the line that says security: and add the following under it:
authorization: "enabled"Save and exit the editor, then restart MongoDB:
sudo systemctl restart mongodStep 8: Create an Admin User

mongoSwitch to the admin database and create a new admin user:
use admin
db.createUser({user: "admin", pwd: "your_password", roles: [{role: "userAdminAnyDatabase", db: "admin"}]})Replace your_password with a strong password.
Step 9: Verify Authentication
Exit the MongoDB shell and try to connect again with authentication:
