1、配置shard所用到的Replica Sets，在每臺服務器上執行以下命令：
[root@localhost ~]# cd /data/mongodbsrs/mongodb/bin/
[root@localhost bin]# ./mongod --shardsvr --replSet shard1 --port 22001 --dbpath /data/mongodbsrs/data/shard1/ --logpath /data/mongodbsrs/log/shard1/shard1.log --logappend --fork
[root@localhost bin]# ./mongod --shardsvr --replSet shard2 --port 22002 --dbpath /data/mongodbsrs/data/shard2/ --logpath /data/mongodbsrs/log/shard2/shard2.log --logappend --fork
[root@localhost bin]# ./mongod --shardsvr --replSet shard3 --port 22003 --dbpath /data/mongodbsrs/data/shard3/ --logpath /data/mongodbsrs/log/shard3/shard3.log --logappend --fork
2、用mongo連接其中任意一臺機器，初始化Replica Sets，分別連接每一個shard的端口號進行Replica Sets的初始化，命令如下：
[root@localhost ~]# cd /data/mongodbsrs/mongodb/bin/
[root@localhost bin]# ./mongo --port 22001
> config = {_id:"shard1",members:[{_id:0,host:"192.168.100.127:22001"},{_id:1,host:"192.168.100.152:22001"},{_id:2,host:"192.168.100.154:22001"}]};
> rs.initiate(config);
[root@localhost ~]# cd /data/mongodbsrs/mongodb/bin/
[root@localhost bin]# ./mongo --port 22002
> config = {_id:"shard2",members:[{_id:0,host:"192.168.100.127:22002"},{_id:1,host:"192.168.100.152:22002"},{_id:2,host:"192.168.100.154:22002"}]};
> rs.initiate(config);
[root@localhost ~]# cd /data/mongodbsrs/mongodb/bin/
[root@localhost bin]# ./mongo --port 22003
> config = {_id:"shard3",members:[{_id:0,host:"192.168.100.127:22003"},{_id:1,host:"192.168.100.152:22003"},{_id:2,host:"192.168.100.154:22003"}]};
> rs.initiate(config);
3、配置每臺Config Server，在每臺服務器上執行以下命令：
[root@localhost bin]# ./mongod --configsvr --dbpath /data/mongodbsrs/data/config/ --port 21000 --logpath /data/mongodbsrs/log/config/config.log --logappend --fork
4、配置每臺Route Process，在每臺服務器上執行以下命令：
[root@localhost bin]# ./mongos --configdb 192.168.100.127:21000,192.168.100.152:21000,192.168.100.154:21000 --port 20000 --chunkSize 1 --logpath /data/mongodbsrs/log/mongos/mongos.log --logappend --fork
5、配置Shard Cluster，連接到其中任意一臺機器的20000端口的mongos進程，並切換到admin數據庫做以下配置：
[root@localhost ~]# cd /data/mongodbsrs/mongodb/bin/
[root@localhost bin]# ./mongo --port 20000
mongos> use admin;
mongos> db.runCommand({addshard:"shard1/192.168.100.127:22001,192.168.100.152:22001,192.168.100.154:22001"});
mongos> db.runCommand({addshard:"shard2/192.168.100.127:22002,192.168.100.152:22002,192.168.100.154:22002"});
mongos> db.runCommand({addshard:"shard3/192.168.100.127:22003,192.168.100.152:22003,192.168.100.154:22003"});
激活數據庫及集合的分片：
mongos> db.runCommand({enablesharding:"testdb"});
mongos> db.runCommand({shardcollection:"testdb.users",key:{_id:1}});
6、驗證Sharding正常工作，連接到其中任意一臺機器的20000端口的mongos進程，並切換到testdb數據庫，以便添加測試數據
[root@localhost ~]# cd /data/mongodbsrs/mongodb/bin/
[root@localhost bin]# ./mongo --port 20000
mongos> use testdb;
mongos> for(var i = 1; i <= 200000; i++)db.users.insert({id:i,addr1:"beijing",addr2:"shanghai"});
mongos> db.users.stats();
