mongodb replication in sharded machine - mongodb

Question

I have done Replication in one single machine with three different port(Say 27018[master],27019,27020). Also I have done Sharding in one single machine with two different port(Say 27021,27022).
Now I have to implement replication for the sharded machine port. I need to implement replication for 27021 and 27022. How can I do this? Please help me to resolve this issue.
Steps followed :
Part 1: Set up 3 port for replication
mongod --replSet rs0
mongod --port 27018 --dbpath F:\Data1 --replSet rs0
mongod --port 27020 --dbpath F:\Data2 --replSet rs0
mongo localhost:27017
rs.initiate()
rs.add("ComputerName:27018")
rs.add("ComputerName:27020")
Part 2: Now set up for sharding
mongod --configsvr --replSet configReplSet
mongod --port 27021 --dbpath F:\Data4 --replSet configReplSet
mongod --port 27025 --dbpath F:\Data5 --replSet configReplSet
mongo 127.0.0.1:27019
rs.initiate({_id:"configReplSet",configsvr:true,members:[{_id: 0,host: "127.0.0.1:27021"},{_id:1,host: "127.0.0.1:27025"}]})
When I run this code I am getting an error:
{
"ok" : 0,
"errmsg" : "No host described in new configuration 1 for replica set configReplSet maps to this node",
"code" : 93
}
So remaining steps I am not able to execute. Any idea how can I overcome this issue?

Answer 1

Got one method to achieve my requirement.
Steps as follows
Config Server and its replication
mongod --configsvr --dbpath F:\Data1\configdb\ --replSet rs2 --port 27017
mongod --configsvr --dbpath F:\Data2\configdb\ --replSet rs2 --port 27018
mongod --configsvr --dbpath F:\Data3\configdb\ --replSet rs2 --port 27019
mongo machineip:27017
config= {_id:"rs2", members :[{ _id:0, host:'10.18.0.225:27017'}, {_id:1, host:'10.18.0.225:27018'}, {_id:2, host:'10.18.0.225:27019'}]}
rs.initiate (config)
rs.status()
Routing Server
mongos -configdb machineip:27017 --port 27020
Shard1 and its replication
mongod --dbpath F:\Data4\db\ --shardsvr --replSet rs0 --port 27021
mongod --dbpath F:\Data5\db\ --shardsvr --replSet rs0 --port 27022
mongod --dbpath F:\Data6\db\ --shardsvr --replSet rs0 --port 27023
Shard2 and its replication
mongod --dbpath F:\Data7\db\ --shardsvr --replSet rs1 --port 27024
mongod --dbpath F:\Data8\db\ --shardsvr --replSet rs1 --port 27025
mongod --dbpath F:\Data9\db\ --shardsvr --replSet rs1 --port 27026
Replication configuration for Shard1
mongo machineip:27021
config= {_id:"rs0", members :[{ _id:0, host:'machineip:27021'},{_id:1,host:'machineip:27022'},{_id:2,host:'machineip:27023'}]}
rs.initiate(config)
rs.status()
Replication configuration for Shard2
mongo machineip:27024
config= {_id:"rs0", members :[{ _id:0, host:'machineip:27024''},{_id:1,host:'machineip:27025''},{_id:2,host:'machineip:27026''}]}
rs.initiate(config)
rs.status()
Sharding Configuration in route server
sh.status()
sh.addShard ("rs0/machineip:27021")
sh.addShard ("rs0/machineip:27024")
sh.status()
sh.enableSharding ("test")
sh.shardCollection ("test.stud", {id: 1})
sh.status()
Hope this will help :-)
