2. ● 2 or more router servers
● 3 config server
● 2 or more shard server
Architecture

3. Sharded Cluster Architecture

4. Setup
All machine install MongoDB
wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.6.1.tgz
tar zxvf mongodb-linux-x86_64-2.6.1.tgz -C /opt/
export PATH=$PATH:/opt/mongodb-linux-x86_64-2.6.1/bin
mkdir -p /data/db

5. Shard Server
Start service mongod on shard server
mongod --dbpath /data/db

6. Config Server
Start service mongod on config server
mongod --configsvr --dbpath /data/db

7. Router Server
Start service mongos on router server
mongos --configdb ◌ํYOUR-CONFIG-SERVER:27019

8. Add Shard to Cluster
Connect to router and add shard to cluster
sh.addShard("YOUR-SHARD-SERVER:27017")

9. Check your cluster status
Check your shard cluster status
sh.status()

10. Test your shard cluster
Select database ‘test’ to sharding
sh.enableSharding("test")

11. Test your shard cluster
Select database push some sample data
use test
for (var i = 1; i <= 10; i++) db.testSample.insert({ x : i })

12. Test your shard cluster
Index your collection
db.testSample.ensureIndex({ _id: "hashed" })

13. Test your shard cluster
Select shard key (Hash Based)
sh.shardCollection("test.testSample",{ "_id": "hashed" });

14. Test your shard cluster
Add more shard server and push more sample
data and see your shard status
