How to install mongodb and how it's work in Windows

History of MongoDB Installation & Usage on Windows

🔹 Pre-2015: Manual Zip Installation

MongoDB distributions for Windows were provided as .zip archives.
Users had to manually:

Unzip the folder (e.g., mongodb-win32-x86_64-3.x.x.zip)
Move it to a location like C:\mongodb
Create data directories manually like C:\data\db
Start MongoDB using mongod.exe via Command Prompt

Services were not installed automatically — users had to run MongoDB manually each time.

🔹 2016–2017: Community Awareness and Blog Tutorials

Tutorials (like yours from February 15, 2016) became popular.
Blogs explained:

How to run multiple MongoDB instances on different ports
How to connect via the mongo client
How to insert JSON documents manually

This period was crucial for learning MongoDB at a grassroots level, especially for developers using Windows as a dev environment.

🔹 2018–2019: MSI Installer + Windows Services

MongoDB provided an MSI installer:

Made setup easier
Added MongoDB as a Windows Service (optional during install)

Users no longer had to manually run mongod.exe
Data directories and logs were auto-configured
MongoDB Compass was introduced for GUI access

🔹 2020–Present: Modern Tools + MongoDB Atlas

Installation now supports:

Chocolatey: choco install mongodb
Windows Subsystem for Linux (WSL): Developers can run MongoDB natively on Linux inside Windows.

Many users moved to MongoDB Atlas (cloud version), reducing the need for local installs.
Windows developers still use local MongoDB for development/testing via MSI or Docker.

How to Mongo DB installation and work out in Windows :

Download MongoDB:
Download mongodb-win32-x86_64-3.0.7.zip from the official MongoDB website, unzip it, and place the folder named mongodb (which contains the bin directory) in the C:\ drive.
Create Database Directory:
In C:\, create the directory C:\data\db for a single instance of MongoDB.
For multiple database instances, create folders like C:\data\db1, C:\data\db2, and so on.
Start MongoDB Server:
Open Command Prompt as Administrator and run:
cd C:\mongodb\bin
mongod.exe --dbpath C:\data\db
This starts MongoDB on the default port 27017.
Start Multiple MongoDB Instances:
To run multiple databases on different ports, use:
mongod.exe --dbpath C:\data\db1 --port 27018
mongod.exe --dbpath C:\data\db2 --port 27019
Open MongoDB Client:
Again in Command Prompt (Admin), navigate to:
cd C:\mongodb\bin
Run mongo to open the default client connected to port 27017.
Connect to Other DB Instances:
Use:
mongo --port 27018
mongo --port 27019

Inserting JSON Data into MongoDB:

After opening the client, you can begin inserting data in JSON format.
Create a collection (like a table) named Customer.

Insert sample JSON data:

Like: {
"firstName": "John",
"lastName": "Smith",
"age": 25,
"address":
{
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": "10021"
},
"phoneNumber":
[
{
"type": "home",
"number": "212 555-1234"
},
{
"type": "fax",
"number": "646 555-4567"
}
]
}
