1) setup mongod on a1/a2/a3

2) Edit mongod.conf on a1/a2/a3

	dbpath=/data
	replSet = rs

	comment out:  bind_ip=127.0.0.1

3) start mongod

4) Initialize replica set

rsconf =  {
	_id: "rs",    members: [
	{ _id: 0 , host:'tja1.mongodb.ga:27017' },
	{ _id: 1, host:'tja2.mongodb.ga:27017' },
	{_id: 2, host:'tja3.mongodb.ga:27017'}
	]
};

rs.initiate(rsconf);


5) Install monitoring agent and start

6)
