By default, MongoDB is listening on 127.0.0.1:27017 only:

Open MongoDB configuration file /etc/mongod.conf and change bindIp by adding required

sudo nano /etc/mongod.conf

# network interfaces  net:  port: 27017  bindIp: 127.0.0.1

> db.createUser({user:"demo", pwd:"demo@123", roles:[{role:"root", db:"admin"}]})

Type this command in the shell to exit the shell:

>exit

Step 5 : Enable MongoDB authentication

sudo nano /lib/systemd/system/mongod.service 

Add the below line into this /lib/systemd/system/mongod.service

 ExecStart=/usr/bin/mongod --quiet --auth --config /etc/mongod.conf

Now connect to the MongoDB shell using this command:

mongo -u demo -p --authenticationDatabase admin

> db.runCommand({connectionStatus : 1})
