Installation Tips and Tricks when Installing Mongodb

Installation of Mongodb 


Some of the steps that needs to be considered while installing MongoDb.


Step1:

64-bit Linux binaries

$ # replace "2.0.2" in the url below with the version you want
$ curl http://downloads.mongodb.org/linux/mongodb-linux-x86_64-2.0.2.tgz > mongo.tgz
$ tar xzf mongo.tgz

Step2: ** Very Important

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.

** Please note without Step 2; you can not run mongod under Linux or ubuntu environment.


Its very essential to create the data/db, since the current version of mongodb does'nt create a database directory.


if your are home directory


$ cd /usr/local 
$ sudo ln -s /home/username/mongo mongodb


$ vim .bashrc 
export PATH="$PATH":/usr/local/mongodb/bin


$source .bashrc


Execute the mongodb server 
$mongod

Run mongodb server with REST enabled.
$mongod --rest
