Make sure you created the /data/db at the root. otherwise, do the simple steps.

For Mac or Linux user

1 - first open the terminal as root.

sudo bash

2 - make db folder 

mkdir -p /data/db

3 - give the chmod 777 to the directory.

chmod 777 /data
chmod 777 /data/db

4 - confirm the /data/db is 777

ls -ld /data/db

5 - exit the root shell

6 - run the mongod cmd at mongodb_path/bin directory.

mongod

make sure it is listing port. By default, it listens to the 27017 port.

7- open the new terminal window and run the mongo cmd at mongodb_path/bin directory.

mongo

For window user

1- create the /data/db at like C:\data\db

2- open the terminal at mongodb_path/bin

mongod

make sure it is listing port. By default, it listens to the 27017 port.

3- open the new terminal window at mongodb_path/bin

In some cases it may happen if you try to reach a mongodb server from another ip and it stops you because of mongodb configurations.

At the location you have installed mongodb (in my computer it is C:\Program Files\MongoDB\Server\4.0\bin) you will see the config file: mongod.cfg. When you open the file for editing you will find some parameters under net part. As default, it is like the following:

network interfaces

net:

port: 27017

bindIp: 127.0.0.1

But if you want to connect to mongodb from another machine you have to change it as following:

network interfaces

net:

port: 27017

bindIp: 0.0.0.0

When you change it as 0.0.0.0, it means it accepts connections from all ip.
