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!
