How to resolve error :dbpath (/data/db/) does not exist permanently in MongoDB

Assuming you have followed the instructions to install a packaged version of MongoDB, you should be starting and stopping mongod using service.

To start mongod:

 sudo service mongodb start

To stop mongod:

 sudo service mongodb stop

If you use the service command to start and stop, it should be using the configuration file: /etc/mongodb.conf.

Starting mongod from the command line

If you run mongod directly instead of using the service definition, you will also have to specify a configuration file as a command line parameter if you want one to be used:

mongod --config /etc/mongodb.conf

Here is how I got this resolved, simply by following their official Doc . HERE.

Step by step from teminal (running ubuntu) :

1. cd into /srv folder =>> cd /srv/
2. make directory =>> mkdir -p mongodb
3. From within /srv/ give the newly created mongodb folder the right permissions and group ......
4. Lastly, run this => mongod --dbpath /srv/mongodb/

"step by step" Copy of the terminal ...... :)

Change the user of the new data directory:

chown mongodb [rute_directory]

And try another time to start the mongo service

service mongodb start

I solve the same problem with this.
