Replica set : 

P1 : ( Primary )
S1 : ( Sec 1 )
A2 : ( Arbiter )



1. start mongo with replica in all instance
  stop iptables
		service iptables stop for all instances

	check if process exist run with replica
		ps -ef | grep mongo
		mongod     964     1  0 05:06 ?        00:00:01 /usr/bin/mongod -f /etc/mongod.conf
		stop the mongo
			service mongod stop

	restart with replica
		mkdir /srv/mongodb/rs0-0
		/usr/bin/mongod --port 27017 --dbpath /srv/mongodb/rs0-0 --replSet rs0 --smallfiles --oplogSize 128
			--smallfiles --oplogSize 128 ( for testing )
		waiting for a while

	into mongo shell - the primary one
		check replica set status
			> rs.status()
				if running with replSet, it should show info with need to initiate
		initiate set
			> cfg = {"_id" : "rs0","members" : [{"_id" : 0,"host" : "ec2-54-245-53-45.us-west-2.compute.amazonaws.com:27017"}]}
		    > rs.initiate(cfg)
		verify
		    > rs.conf()
		    rs0:PRIMARY>
		    > db.isMaster()

2. add members
	in other node
		service iptables stop
		mkdir /srv/mongodb/rs0-1
		> /usr/bin/mongod --port 27017 --dbpath /srv/mongodb/rs0-1 --replSet rs0 --smallfiles --oplogSize 128
	in Primary
		> rs.add( "<node's public ip>:27017" )
		> rs.conf()

3. add arbiter
	in arbiter node
		service iptables stop
		mkdir /srv/mongodb/arb
		> mongod --port 30000 --dbpath /srv/mongodb/arb --replSet rs0 --smallfiles --oplogSize 128
	in Primary
		> rs.addArb("<node's public ip>:30000")
		> rs.conf()
