Mongo by default writes data to /data folder and the user who is running mongo service does not have permission to create /data folder.

You can get this information from this log snippet

2017-05-05T23:33:06.816+0600 I STORAGE  [initandlisten] exception in initAndListen: 29 Data directory /data/db not found., terminating
2017-05-05T23:33:06.816+0600 I NETWORK  [initandlisten] shutdown: going to close listening sockets...

So, you need to do this

sudo mkdir /data/db
sudo chown $USER -R /data/db # give permission to the user who is running mongo service

Looks like you need to create the /data/db folder

try doing this in the terminal

sudo mkdir /data/db

then start mongodb

first run mongod.exe If it gives any warnings regarding unsafe shutdowns, metrics, diagnostics ignore them and run mongo.exe in another CLI(mand line Interface).

Even then if it does not work, just backup the ../data/db directories and redo the database.

Before access the db using a database driver(eg: mongoose,mongojs) make sure that the database is up and running.

$ mongo
MongoDB shell version v3.4.4
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.4
use YourAwesomeDatabaseName
switched to db YourAwesomeDatabaseName

You are good to go!

I had an issue /mongo.js:237:13 in local terminal trying to run GCP-hosted mongo. I fixed it by removing tags in GCP

hey there This is the issue because of your mongodb server is not running

you can verify this by

sudo service mongodb status

** you need to start the server by running mand

sudo service mongodb start

Good Luck
