How to Use MongoDB on Debian 12

You can use MongoDB through its command-line interface i.e. MongoDB shell. For this purpose, you must connect to the MongoDB server and access the MongoDB shell. Then, you will be able to perform various operations, such as viewing, creating, and using MongoDB databases, managing collections, and many more. Go through the following steps to use MongoDB on Debian 12:

Connect to the MongoDB Server

To interact with MongoDB, connect to the MongoDB server using the provided command:

As you can see, the MongoDB shell has been started:

Display All MongoDB Databases

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

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:

Create MongoDB Collection (Table)

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

db.createCollection(“TechAuthors”)

Show All Collections (Tables)

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

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

If you want to delete the specific data of the MongoDB collection, utilize the “db.TechAuthors.remove()” command and specify the required condition:

db.TechAuthors.remove({name: ‘John’})

Delete MongoDB Database

To delete the current MongoDB database, write out the following command:

Exit MongoDB Shell

You can close the current MongoDB shell session as:

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:

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:

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:

db.createUser(
{
user: “LWadmin”,
pwd: “pass123”,
roles: [ { role: “userAdminAnyDatabase”, db: “admin” } ]
}
)

Step 6: Close MongoDB Shell

Next, use the provided command to exit the MongoDB Shell:

Step 7: Test MongoDB Authentication

Finally, connect to the MongoDB with the new user to ensure its authentication. After executing the below command, you will be asked to enter the password. Enter the desired password that you have set for this user:

mongo –port 27017 –authenticationDatabase “admin” -u “LWadmin” -p

The output indicates that we have successfully connected to the MongoDB server with the new username and password:
