mongo-Replica set Shard test

1. Start a pair of replica sets (Increase shard parameters)

D:\mongodb>mongod--dbpath=d:\mongodb\db--port 2222--replset neu/127.0.0.1:3333 --shardsvr

E:\mongodb>mongod--dbpath=e:\mongodb\db--port 3333--replset neu/127.0.0.1:2222 --shardsvr

2. Commencement of arbitration

F:\mongodb>mongod--dbpath=f:\mongodb\db--port 4444--replset neu/127.0.0.1:2222

3. Start the Configuration library

G:\mongodb>mongod--dbpath=g:\mongodb\configdb--port 30000 --configsvr

4. Start MONGOs

c:\>mongos --port 20000--configdb 127.0.0.1:30000

5. Connect to MONGOs, configure Shard Information

C:\>mongo 127.0.0.1:20000/admin
