In the first post on MongoDB, we had a very brief introduction. MongoDB can be installed on a MAC, Windows and Linux system.

Installation

This tutorial is (for now) focused on Ubuntu. MAC and Windows users can directly download the package from MongoDB Downloads page and follow the instructions.

Installing MondoDB in Ubuntu is as simple as running the following command:

sudo apt-get install mongodb

As mentioned above that Ubuntu already has MongoDB package in its repositories but 10gen packages are more up to date. Following these steps will ensure 10gen’s MongoDB installation:

Public GPG Key of 10gen to ensure authenticity

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

Add 10gen Repository
Either add the following line to the end of the /etc/apt/sources.list file or create a new file named /etc/apt/sources.list.d/10gen.list with these following contents:

deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen

Update with the new Repository

sudo apt-get update

Finally the actual installation

sudo apt-get install mongodb-10gen

Configure MongoDB

MongoDB on Ubuntu uses /var/lib/mongodb for storing data and /var/log/mongodb/mongodb.log for logging. This can be changed from the configuration file:

sudo vim /etc/mongodb.conf

Additionally the control script of MongoDB is located /etc/init.d/mongodb. The account used to run the MongoDB instance is mongodb user account. The directories mentioned above already have permissions with this account.

Starting & Stopping MongoDB

The service name is mongod for MongoDB>. To start it:

sudo service mongodb start

To stop it:

sudo service mongodb stop

Now that MongoDB is installed and running, we will start with actually using it in the next post.
