Easiest way to create MongoDB Cluster in MacOS

An easiest way to create mongodb cluster in MacOs environment.

These steps can be executed one after the other in Mac Terminal.
Note: Make sure that the folders paths are correct before running these commands.

Create Initial directories required for mongo db cluter

cd /Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data

mkdir replica1 replica2 replica3 replica4 replica5 replica6 replica7 replica8 replica9 config1 config2 config3

Sudo chmod –R 777 repl*

Sudo chmod –R 777 conf*

shard1

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica1 –port=27011 –bind_ip_all –replSet=replica1 –shardsvr

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica2 –port=27012 –bind_ip_all –replSet=replica1 –shardsvr

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica3 –port=27013 –bind_ip_all –replSet=replica1 –shardsvr

rs.initiate({_id:”replica1″,members:[{“_id”:1,”host”:”localhost:27011″}]})

rs.add(“localhost:27012”)

rs.add(“localhost:27013”)

shard2

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica4 –port=27021 –bind_ip_all –replSet=replica2 –shardsvr

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica5 –port=27022 –bind_ip_all –replSet=replica2 –shardsvr

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica6 –port=27023 –bind_ip_all –replSet=replica2 –shardsvr

rs.initiate({_id:”replica2″,members:[{“_id”:1,”host”:”localhost:27021″}]})

rs.add(“localhost:27022”)

rs.add(“localhost:27023”)

Shard 3

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica7 –port=27031 –bind_ip_all –replSet=replica3 –shardsvr

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica8 –port=27032 –bind_ip_all –replSet=replica3 –shardsvr

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/replica9 –port=27033 –bind_ip_all –replSet=replica3 –shardsvr

rs.initiate({_id:”replica3″,members:[{“_id”:1,”host”:”localhost:27031″}]})

rs.add(“localhost:27032”)

rs.add(“localhost:27033”)

config

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/config1 –port=27018 –bind_ip_all –replSet=config1 –configsvr

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/config2 –port=27019 –bind_ip_all –replSet=config1 –configsvr

./mongod –dbpath=/Users/prabhu/Documents/softwares/mongodb-osx-x86_64-4.0.6/bin/data/config3 –port=27020 –bind_ip_all –replSet=config1 –configsvr

rs.initiate({_id:”config1″,members:[{“_id”:1,”host”:”localhost:27018″}]})

rs.add(“localhost:27019”)

rs.add(“localhost:27020”)

Start Mongos with config cluster
./mongos –configdb=”config1/localhost:27018,localhost:27019,localhost:27020″ –port=27017 –bind_ip_all

Connect to Mongos Server
./mongod –port 27017

sh.addShard(“replica1/localhost27011”)

sh.addShard(“replica2/localhost27021”)

sh.addShard(“replica3/localhost27031”)

sharding Collection

sh.enableSharding(“shoppingdb”); // enable sharding for db

sh.shardCollection(“shoppingdb.Orders”,{_id:1},true); // shard the collection
