ubuntu - bash: mongodb/bin/mongod : No such file or directory -

I'm trying to install and run some basic commands from it on mongodb .

So far,

1. I downloaded a 32-bit ZIP file from
2. I will unzip the file in the following locations
3. I have created data called a folder, then another db
4. I have created a filename in which I would like to store my data, where it will be mongodb / data / db .

But when the path of the folder occurs then mongodb.config I run the command to start the server:

  user1 @ user1-virtualbox: ~ $ mongodb / bin / mongod --dbpath ~ mongodb / data / db  

I get the following error:

  bash: mongodb / bin / mongod: any such file or directory  

Am I missing something is?
