Database is used to store the data. In our case, we are using MongoDB Compass GUI and MongoDB Community versions.

Following process is for MacOS:

1. Download MongoDB Community Server tgz package. :-

2. Go to your Users directory.

3. Create a “data/db” folder in your system’s User folder.

e.g My Users folder name is d5

— Inside the data/db folder all your MongoDB related files or data go.

4. Open the new tab with “db” folder using the “New Terminal at Folder”

5. Check the present working directory using “pwd” command.

Copy the pwd present working directory path

6. Copy the “pwd” “present working directory” path.

7. Unzip community server.

8. Get into the main “community server folder”, Open the “bin” folder by right clicking and selecting “New Terminal at Folder”

9. On the terminal type, type the: ./mongod command, followed by –dbpath tag just after type pwd path that you obtained earlier /Users/d5/data/db.

/mongod --dbpath /Users/{your_system's_user_name}/data/db

Ensure that you removed the “{}” curly braces around the system name!

10. Download the MongoDB Compass GUI.

11. Click on Connect button, make sure to follow the above process before you start the MongoDB Compass GUI.
