Week 6 - Sample code to create MongoDB Replica Set

create_replica_set.sh

#!/bin/bash
mkdir -p /data/rs1 /data/rs2 /data/rs3
mongod --replSet m101 --logpath "1.log" --dbpath /data/rs1 --port 27017 --smallfiles --fork
mongod --replSet m101 --logpath "2.log" --dbpath /data/rs2 --port 27018 --smallfiles --fork
mongod --replSet m101 --logpath "3.log" --dbpath /data/rs3 --port 27019 --smallfiles --fork

init_replica.js

config = { _id: "m101", members:[
          { _id : 0, host : "localhost:27017"},
          { _id : 1, host : "localhost:27018"},
          { _id : 2, host : "localhost:27019"} ]
};

rs.initiate(config);
rs.status();
