Sharding Group Members :
For sharding there are three players.
For a mongo shard we need to setup the above three servers.
Config Server Setup : add the following to mongod conf file
sharding: clusterRole: configsvr replication: replSetName: <setname>
run : mongod --config
we can choose config server as replica set or may be a standalone server. Based on our requirement we can choose the best. If config need to run in replica set we need to follow the replica set setup
Replica Setup : Create replica set // Please refer the replica setup
MongoS Setup : Mongos is main setup in shard. Its is query router to access all replica sets
Add the following in mongos conf file
sharding: configDB: <configReplSetName>/cfg1.example.net:27017;
Configure Shared :
Connect the mongos via shell (mongo --host --port )
