Setting Up MongoDB with Authentication

Step 1: Start MongoDB with Authentication

• First, ensure that your MongoDB instance is running with authentication enabled. You can do this by editing the MongoDB configuration file (mongod.conf) and setting the security option:

security:
  authorization: enabled

• After updating the configuration file, restart the MongoDB service:

sudo systemctl restart mongod

Step 2: Create a User in MongoDB

• To connect with authentication, you need a user with appropriate permissions. Connect to your MongoDB instance and create a user:

mongo

• Inside the MongoDB shell, switch to the admin database and create a user:

use admin

db.createUser({
  user: "myUserAdmin",
  pwd: "abc123",
  roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})
