This configuration was tested on MongoDB 2.6 and maybe not compatible with other versions.
Continuing a line of configuration of the post Creating admin user on MongoDB 2.6, now we enable external access to the MongoDB.
Like everything on Linux or most, there is a folder with configuration files or the configuration file is inside the
/etc folder. In this case the file name is
bind parameter to 0.0.0.0 (anyone connects) or to the specific IP you want to connect to MongoDB.
Restart the service for the changes to take effect:
$ sudo systemctl restart mongodb.service
