Answer 1

what OS are you using? In ubuntu you need to check your version:

service mongod status, mongod --version.

If mongod is off then just restart and write the error if possible.

service mongod restart

Answer 2

if you are using linux, try this command

$ sudo mongod

you are getting that because you are running

$ mongo

Answer 3

First go to your mongoDB directory and in that directory go to bin directory and open terminal in that directory(bin), then run the following command:

mongod.exe

After that open another terminal in same directory and run the following command.

mongo.exe

It will resolve this issue.

Answer 4

first you check it mongodb proper installed or not and also check it version compatibility

I am saying windows os setup, set environment variable is path C:\Program Files\MongoDB\Server\3.6\bin; then open your command prompt and type

mongod

after open another command prompt and type

mongo
