I've tried following the installation instructions laid out here: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
But I run into a problem with, I'm guessing, Upstart/initctl and I can't get the mongod service to start other than by running it manually as sudo in a terminal, which is a Bad Idea IMO. (Even if this is merely for a classroom, single-user setup.)
sudo /etc/init.d/mongod start
Yields this error:
initctl: Unknown job: mongod
I've tried sudo initctl reload-configuration
and running the above start command again, to no avail.
Any ideas or suggestions on what to do next?
