How to install MongoDB on Debian 11

MongoDB is a 2009-released NoSQL database that provides a flexible schema approach. It enables developers to rapidly construct applications and websites without spending much time setting a Database. It is fundamentally distinct from relational databases like Oracle, MySQL, and Microsoft SQL Server.

The term MongoDB is derived from “humongous,” which essentially translates to “huge.” MongoDB may also be used to store both structured and unstructured data. Numerous Professionals install MongoDB on Debian due to its adaptable and quick environment. MongoDB on Debian allows users to create scalable apps and utilize other Linux capabilities.

Most businesses favour Relational Database Management Systems (RDBMS) for storing and retrieving data. There are several benefits to using a DBMS. For instance, it provides enhanced Data Integration, transmission, and security options. It enables developers to generate rapid Database query solutions. If you’re looking for a solution to help standardize file usage, store data securely, and increase data accessibility, you’ve come to the right place.

Developers utilize MongoDB in Debian since it provides a vast array of tools via an open-source Linux interface. This post will explain how to install MongoDB Debian in easy stages and how to use MongoDB once the installation is complete.

Key features of MongoDB

MongoDB’s exceptional capabilities contribute to its widespread usability and popularity. Let’s examine the significant technological characteristics of MongoDB:


Indexing is an essential component of a Database for enhancing search speed and query performance. Without indexing, a database would have to scan each page individually to determine which ones fit the query, which would be wasteful. However, the server can execute user requests rapidly if each query has an acceptable index. With MongoDB, any field or key in a document may be indexed, enabling complicated access patterns to datasets.

Facilitates Adhoc Queries

One of the most significant advantages distinguishing MongoDB is its efficiency while processing ad hoc queries on data that are typically updated in real-time. MongoDB supports field searches, range searches, and queries with regular expressions.

Schema-Less Database

Using a schema, traditional relational databases specify each functional element, including tables, rows, views, indexes, and relationships. In MongoDB, one collection keeps various documents. It has no schema. Therefore a collection may include many documents with separate keys, which may be unique. A schemaless database, such as MongoDB, is more flexible since it lacks these initial limitations and corresponds to a more “natural” database.

Install MongoDB on Debian

Follow the steps provided herein to install MongoDB on Debian 11.

Step 1: Install the MongoDB Debian Dependencies

Install the MongoDB Debian requirements with the command below.

sudo apt-get install gnupg2 wget -y
install mongodb dependencies
Install MongoDB dependencies

The MongoDB package is not included by default in the Debian repository. Therefore, you must add and install the official MongoDB repository for Debian to APT. Execute the following line of code in the terminal to include the official MongoDB repository.

wget -qO - | sudo apt-key add -

echo "deb buster/mongodb-org/5.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
add mongodb repo
Add MongoDB repo

Once you are done, update the repository cache with the following command:

sudo apt-get update -y
update repo caches
Update repo caches

Step 2: Integrate the GPG key for MongoDB

To confirm that the packages we will obtain in order to install this database on Linux come from a legitimate source. Add the GPG key signed by the Database server’s developers.

Note: This step is optional

curl -sSL  -o mongoserver.asc

gpg --no-default-keyring --keyring ./mongo_key_temp.gpg --import ./mongoserver.asc

gpg --no-default-keyring --keyring ./mongo_key_temp.gpg --export > ./mongoserver_key.gpg

sudo mv mongoserver_key.gpg /etc/apt/trusted.gpg.d/
intergrate gpg key
Intergrate GPG Key

Step 3: Run system update

On your Debian 11 terminal, execute a system update to ensure that all existing packages are up-to-date.

sudo apt update
update resources
Update resources

Step 4: Install MongoDB on Debian11 Bullseye

That is all. We have already established the prerequisites for installing “database-tools, mongosh, additional tools, mongos; database server and shell” on Debian 11 bullseye

Hence, perform a simple command:

sudo apt install mongodb-org


sudo apt-get install mongodb-org -y
install mongodb
Install MongoDB

After successfully installing the MongoDB Debian package, verify the MongoDB version using the command below.

mongod --version
mongodb version
MOngoDB version

Step 5: Enable and start the MongoDB service

Enable and start the Database server service after the installation is complete so that we do not need to run it every time the system boots.

sudo systemctl enable --now mongod
enable mongodb
Enable MongoDB

Proceed and check the MongoDB status by executing the command below:

sudo systemctl status mongod
check mongodb status
Check MongoDB status

Step 6: Configure MongoDB

MongoDB is set by default to allow access without a password. It is always suggested to protect MongoDB using a username and password for security purposes.

To enable MongoDB authentication, you must modify the MongoDB configuration file:

sudo nano /etc/mongod.conf

Append the following lines to the mongod.conf file:


authorization: enabled
mongodb authorization file
MongoDB authorization file

After executing the file, save and close it, then restart the MongoDB service to effect the modifications.

systemctl restart mongod
restart mongodb
Restart MongoDB

Next, you must create an admin user to complete the administrative operation. First, connect to the MongoDB using the command below:

connect to mongo
Connect to mongo

Once connected, use the following command to establish an admin Database:

use admin
use admin
Use admin

Next, establish an administrator account and set the password using the command:

> db.createUser(


user: "fosslinux",

pwd: "fosslinux123",

roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]


create admin user
Create admin user

Next, terminate the MongoDB shell with the following command:

quit mongo server
Quit mongo server

Step 7: How to alter MongoDB Debian default path?

The primary location for storing MongoDB data is /var/lib/mongo. However, this directory can be modified in the following manner:

  • Stopping the MongoDB service is required.
sudo systemctl stop mongod.service


stop mongodb
Stop MongoDB
  • Create a new MongoDB data directory.
mkdir fosslinux
create fosslinux directory
Create fosslinux directory
  • Set the directory’s ownership to MongoDB.
sudo chown -R mongodb:mongodb fosslinux
set directory ownership
Set directory ownership
  • Replace the previous directory with the current one. To install Rsync, do sudo apt install rsync.
sudo rsync -av /var/lib/mongodb fosslinux
replace previous directory with current one
Replace previous directory with current one
  • Rename the previous backup directory.
sudo mv /var/lib/mongodb /var/lib/mongodb.bak
rename previous directory
Rename previous directory
  • Establish a symbolic link to the new location.
sudo ln -s fosslinux /var/lib/mongodb
create a symbolic link
Create a symbolic link
  • After making these adjustments, restart the MongoDB service. MongoDB will immediately begin saving its data in the newly-created directory.
sudo systemctl start mongod.service
restart mongodb
Restart MongoDB

Step 8: Enable Remote Connections

To allow distant connections, you must change the same file and add your private or internal IP address to the network interfaces. Your settings should be like the one seen below.

sudo nano /etc/mongod.conf

port: 27017

enable remote connections
Enable remote connections

Replace the IP address ( with your own IP address.

If a firewall exists, open port 27017.

Start MongoDB again.

sudo systemctl restart mongod
restart mongodb service
Restart MongoDB service

Verify whether MongoDB permits remote connections with the following command.

sudo lsof -i | grep mongo
verify mongodb remote connection
Verify MongoDB remote connection

How to uninstall or remove MongoDB on Debian 11

Those who are no longer interested in MongoDB and have no need for it can delete it using the command below:

sudo apt remove mongodb-org


MongoDB is a document-oriented db that gathers and stores data in compressed BSON files. Depending on their needs, developers may extract the gathered documents and information in JSON format. In addition, installing MongoDB Debian facilitates the development of applications with rapid performance because of its scalability features and customizable document schemas.
