MongoDB Shard Cluster configuration

Reference http://scholar.blog.51cto.com/9985645/1673939

First, the environment

Mongodb-1 192.168.3.31 MONGOs

Mongodb-2 192.168.3.32 Shard1

Mongodb-3 192.168.3.33 Shard2

Mongodb-4 192.168.3.34 config server

Second, the configuration process Clean up the data (I'm here for other MongoDB experiments)

5 . Add the Shard node

on MONGOs

enable the Shard feature on the desired object

The sharding feature is turned on, and we'll create the data manually to verify that the

is fragmented.
