2. Extract the tar file to some directory.

$ chown -R hduser:hadoop /learn/mongodb

4. Add the env var in .bashrc
export MONGO_HOME=/learn/mongodb
export PATH=$PATH:$MONGO_HOME/bin


5. Create the default DB directory for Mongo
$ mkdir -R /data/db
$ chown -R hduser:hadoop /data/db

This is by default, you can specify ur db path when starting the mongo db


mongod --dbpath /app/mongodata
this command will start the mongodb. in other terminal you can start work on db. "--dbpath /app/mongodata" is totally optional

If you just use just $ mongod , it will start n use the default db which we have defined in step 5.

Please don't close the current terminal, It can be kill the mongodb process.
