Answer 1

Running Ubuntu 11.10 confirm you have the latest version of MongoDB:

$ mongod --version

db version v2.2.0

(If you don't have the latest version of MongoDB, follow the Ubuntu Installation instructions at: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/)

First confirm that the mongodb user/group has permission to write to the data directory:

$ sudo chown -R mongodb:mongodb /var/lib/mongodb/.

Start up MongoDB as a Daemon (background process) using the following command:

$ mongod --fork --dbpath /var/lib/mongodb/ --smallfiles --logpath /var/log/mongodb.log --logappend

To Shut Down MongoDB enter the Mongo CLI, access the admin and issue the shutdown command:

$ ./mongo

> use admin

> db.shutdownServer()
