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:
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:
{
user: "LWadmin",
pwd: "pass123",
