a. Routing machine (192.168.8.82):

A Mui 1. Enter the terminal: mongo

A Murray 2. Add slicer:

Sh.addShard ("192.168.83VOV 27017") sh.addShard ("192.168.84VOV 27017")

A Murray 3. Check the status of the slicer:

Sh.status ()

A Murray 4. Add a sharding database:

Sh.enableSharding ("testdb")

A Murray 5. Add an index:

Sh.shardCollection ("testdb.user", {name:1,age:1})

A Murray 6. Add test data:

For (I = 1 name:'user'+i,age: (i0), addr:'#'+i}}) {name:'user'+i,age: (i0)

b. Slicer (192.168.8.83GP84):

BMY 1. Enter the terminal:

Mongo

BMY 2. View the sharded data:

Use testdbdb.user.find ()
