Install MongoDB
wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-1.5.5.tgz debian:/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!

Summary : High-performance, schema-free document-oriented database
URL : http://www.mongodb.org
License : AGPLv3 and zlib and ASL 2.0
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).
