Setting up a MongoDB replica set or load balancer using the Windows command prompt involves specific commands and configurations. Below are the steps for both approaches:
1. Setting Up a MongoDB Replica Set on Windows Using Command Prompt:
Prerequisites:
- MongoDB installed on Windows.
- Administrative privileges to create and manage directories.

mongodb-win32-x86_64-3.0.7.zip file 1. Unzip a particular location like :
D:\Software\MongoDb 2. Inside D drive create a folder like
data 3. Again create another three folder
like db,db1,db2 Below command
d:>mkdir
\data\rs1 \data\rs2 \data\rs3 D:\Software\MongoDb\mongodb\bin>mongod
--replSet kartik --logpath \data\rs1\1.log --dbpath \data\rs1 --port 27017
--smallfiles --oplogSize 64 4. Now start the mongo service by below
command below: mongod --port
"PORT" --dbpath "YOUR_DB_DATA_PATH" --replSet
"REPLICA_SET_INSTANCE_NAME" 1) D:\Software\MongoDb\mongodb\bin>mongod
--replSet kartik --logpath \data\rs1\1.log --dbpath \data\rs1 --port 27017
--smallfiles --oplogSize 64 2) D:\Software\MongoDb\mongodb\bin>mongod
--replSet kartik --logpath \data\rs2\2.log --dbpath \data\rs2 --port 27018
--smallfiles --oplogSize 64 3) D:\Software\MongoDb\mongodb\bin>mongod
--replSet kartik --logpath \data\rs3\3.log --dbpath \data\rs3 --port 27019
--smallfiles --oplogSize 64 5. Now start the mongo server below
command: mongo.exe or mongo --host "host
name" --port 27017 like mongo --host "192.168.208.181" --port
27017 D:\Software\MongoDb\mongodb\bin>mongo.exe or goto line no 199 MongoDB shell version: 3.0.7 connecting to: test > rs.initiate() { "info2" : "no
