MongoDb: Install

MongoDB: document oriented database management system.

MongoDB is high performance, reliable document oriented dbms, which solve horizontal scaling problem of large database.

Installation steps on window:
Download the zip as per your system configuration. I've downloaded for 32-bit window.
Extract it anywhere on your system.

Pre-Installation Step
MongoDB need to be told where to create and store database files.
so,  create  /data/db directory anywhere on your system.
I've created it inside the mongodb extracted files as it make more sense. :P

mkdir data
mkdir ./data/db



Once done, move inside mongodb /bin directory via command prompt and launch the mongodb daemon .

D:\dev_bin\mongo\bin>mongod --dbpath=./data/db

dbpath : path to your data/db directory which we created above.
NOTE: in some system dbpath may be required or else you'll get some error.

Additional options:>

--logpath /path/to/logFile

  ->to store all detail in a fill

Check it:

NOw, your daemon is up and running, it's time to get a taste of mongodb. So, fire up the mongo shell: javascript shell.

open new command prompt and  make sure you're in the mongo's /bin directory via command prompt. launch the mongo shell as follow:

mongo.exe

>

Now, you're in mongo shell. By default mongodb has an truncated database 'test' already made.  which you can queries as this:

Now, hug yourself , you got your mongodb up and running.

Cause : This normally occur when  you don't provide mongodb the database saving directory path.
So, instead of making haste, hold a second and as a courtesy to mongodb, please provide dbpath also.
eg:  mongod --dbpath=./data/db
