• Run the Windows Installer from the Windows Command Interpreter.

  • Open CMD as Administrator.

  • Use the .msi installer to install all MongoDB binaries, including MongoDB Compass.

  • From the Command Interpreter, go to the directory containing the .msi installation binary and run:

msiexec.exe /l*v mdbinstall.log  /qb /i mongodb-windows-x86_64-6.0-signed.msi

• The operation installs the binaries to the default directory.

 C:\Program Files\MongoDB\Server\6.0\bin.

  • Click OKs to save changes.

• Now, create a folder named data having a sub-folder named DB where you want to run the server.

• Start the command prompt from there. Either changing the path in cmd or clicking on the Open command window here which would be visible after right-clicking on the empty space of the folder GUI by pressing the Shift and Ctrl keys together.

• Write the command to start the server: mongod

  • It would start the server on port 27017 by default.

• Open another command prompt and type the following to start the client: mongo

• By default, it connects to the test database. If you see the line connecting to the test. Then you have successfully installed MongoDB. Congrats! Now, you can test Hello World to be more confident
