Install MongoDB

wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-1.5.5.tgzdebian:/srv# tar zxf mongodb-linux-x86_64-1.5.5.tgz
debian:/srv# ln -s mongodb-linux-x86_64-1.5.5 mongodb

Create a data directory

By default MongoDB will store data in /data/db, but it won't automatically create that directory. To create it, do:

$ sudo mkdir -p /data/db/
$ sudo chown `id -u` /data/db

You can also tell MongoDB to use a different data directory, with the --dbpath option.

Run and connect to the server

First, start the MongoDB server in one terminal:

$ ./mongodb/bin/mongod

In a separate terminal, start the shell, which will connect to localhost by default:

$ ./mongodb/bin/mongo
> db.foo.save( { a : 1 } )
> db.foo.find()

Congratulations, you've just saved and retrieved your first document with MongoDB!

Description : Mongo (from "humongous") is a high-performance, open source, schema-free: document-oriented database. MongoDB is written in C++ and offers the following: features::     * Collection oriented storage: easy storage of object/JSON-style data:     * Dynamic queries:     * Full index support, including on inner objects and embedded arrays:     * Query profiling:     * Replication and fail-over support:     * Efficient storage of binary data including large objects (e.g. photos:     and videos):     * Auto-sharding for cloud-level scalability (currently in early alpha):     * Commercial Support Available: : A key goal of MongoDB is to bridge the gap between key/value stores (which are: fast and highly scalable) and traditional RDBMS systems (which are deep in: functionality).

$collection->insert($obj);// add another element, with a different "shape"
$obj = array( "title" => "XKCD", "online" => true );
$collection->insert($obj);// find everything in the collection
$cursor = $collection->find();// iterate through the results
foreach ($cursor as $obj) {echo $obj["title"] . "\n";
