We need to prepare a ubuntu-server with MongoDB. We managed to install it properly. When we type:
sudo mongod
this is our result:
XXX@ubuntu-vm:~$ sudo mongod
[sudo] password for XXX:
mongod --help for help and startup options

After that, nothing happens. I keeps saying:

2014-11-01T14:48:19.770+0100 [clientcursormon] mapped (incl journal view):160
2014-11-01T14:48:19.770+0100 [clientcursormon] connections:0
Could anybody tell us what is happening here? We just need MongoDB installed. We have a admin account with all rights. We need make sure we can start the MongoDB server and manage it through a GUI.
When we type: mongo Result:
2014-11-01T15:30:22.616+0100 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed
Another try:
XXX@ubuntu-vm:~$ sudo service mongod start

XXX@ubuntu-vm:~$ sudo mongod

Thanks in advance. We appreciate any comment/answer.

MongoDB installed correctly. What you need to do is configure it (edit /etc/mongodb.conf) enable the service (sudo service mongod start).
Both of which, you will note, are clearly documented (as well as everything else you need to do to get MongoDB up and running on a Ubuntu machine) at the very first link Google returns when you search for "ubuntu mongodb install": http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
As for the "0 connections" thing, it simply means that nobody is connecting to your database server (which makes perfect sense given that you're in the process of setting it up -- your production applications that use MongoDB shouldn't be started until the DB server is up and running).
