New to MongoDB Can not run command mongo
For that your log output states it correct
exception in initAndListen: 10296 dbpath (/data/db) does not exist, terminating
Just you create this directory or better to define it as a configuration value within your configuration file then use it as mongod -f C:\path\to\your\mongodb.conf.
You should manually create a data folder for after installing the MongoDB.
By default MongoDB will store data in /data/db, but it won't automatically create that directory. To create it, do: $ sudo mkdir -p /data/db/ $ sudo chown `id -u` /data/db You can also tell MongoDB to use a different data directory, with the --dbpath option.
