Display All MongoDB Databases

To display all the available MongoDB databases, enter the given command:

show dbs

Switch or Create a Database

If you want to create a new MongoDB database or switch to the specific existing database, execute the “use <database-name>” command and specify the desired database name:

use DebianDB

Create MongoDB Collection (Table)

To create a MongoDB collection (table) in the database, utilize the “db.createCollection(“<collection-name>”)” command:


Show All Collections (Tables)

You can display all the MongoDB collections via the below “show” command:

show collections

Insert Value in MongoDB Collection

If you want to insert values in the specific MongoDB collection/table, you can do it as follows:

db.TechAuthors.insert({ 'name': 'John', 'category': 'Linux', 'experience': 6})

Display MongoDB Collection’s Data

To display all the data of the MongoDB collection, type out the given command:


Delete Data From the MongoDB Collection

How to Configure MongoDB Security on Debian 12

By default, MongoDB doesn’t have authentication enabled which means anyone can access it and connect to the server without a password. Therefore, you should configure your MongoDB security with the username and password on your Debian system to protect your data, prevent unauthorized access, and maintain privacy.

Here are the steps to configure MongoDB security on your system:

Step 1: Enable Authorization

First, open the MongoDB configuration file i.e., “/etc/mongod.conf” with sudo privileges:

sudo nano /etc/mongod.conf

In the “/etc/mongod.conf” file, find the line that starts with “#security” and uncommit it by removing the “#” with it. Then, add the provided line below it:

authorization: enabled

Save the file and close the nano editor by pressing “CTRL + S” and “CTRL + X” respectively.

Step 2: Restart MongoDB Service

After that, you need to restart the MongoDB service to implement changes:

sudo systemctl restart mongod

Step 3: Access MongoDB Shell

Then, connect to the MongoDB server and access the MongoDB shell through the below-listed command:


Step 4: Switch to Admin Database

Now, switch to the “admin” database via the “use” command for creating a new user:

use admin

Step 5: Create a New User

To create a new user in the database, utilize the “db.createUser()” command and specify the username, password, and its role as seen below:

user: "LWadmin",
pwd: "pass123",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]

Step 6: Close MongoDB Shell
