3、配置3台config server

/app/mongo/mongodb/bin/mongod --configsvr --dbpath /app/mongo/data/config --port 20000 --logpath /app/mongo/data/config/config.log --logappend --fork

4、配置3台Route Process

/app/mongo/mongodb/bin/mongos --configdb 132.42.33.212:20000,132.42.33.213:20000,132.42.33.214:20000 --port 30000 --chunkSize 1 --logpath /app/mongo/data/mongos.log --logappend --fork

5、配置Shard Cluster

用mongo连接其中一台机器的30000端口的mongod，并切换为admin 数据库，进行配置Sharding环境，如下面的代码所示：

[mongodb@Hadoop4 mongo]$ /app/mongo/mongodb/bin/mongo --port 30000

>use admin

>db.runCommand({addshard:"shard1/132.42.33.212:27017,shard1/132.42.33.213:27017,shard1/132.42.33.214:27017"}) www.2cto.com

>db.runCommand({addshard:"shard2/132.42.33.212:27018,shard1/132.42.33.213:27018,shard1/132.42.33.214:27018"})

>db.runCommand({enablesharding:"test"})

>db.runCommand({shardcollection:"test.users",key:{_id:1}})

6、验证Sharding

连接其中一台端口30000对应的mongos进程，并切换到test数据库

use test

for(var i=1;i<=200000;i++) {db.users.insert({id:i,addr_1:"beijing",addr_2:"shanghai"})}

db.users.stats()
