MongoDB - Day 2 (Install MongoDB in Windows)

Today I will explain how to install MongoDB in Windows. You can read my previous MongoDB introduction article from here:

• Introduction to MongoDB

Now I will explain how to install MongoDB in a simple procedure.

Step 1

First go to the MongoDB website and download an appropriate version of MongoDB for your system.
             Download MongoDB.


Step 2

After downloading the MongoDB installation package run the MSI file.



Step 3

Accept the license.



Step 4

Choose the Setup Type.



Step 5

Install MongoDB.



Step 6

The following shows the installation process.



Step 7

The installation is complete.



After successful installation of MongoDB you will find that a folder named MondoDB has been created in your directory. You can find this folder here: C:\Program Files.



Step 8

After installation now we set the path for MondoDB. For this select the following path from your directory:

C:\Program Files\MondoDB\Server\3.0\bin.



Step 9

Now go to System Properties and press the Environment Variables button.



Step 10

Select the Path variable from the System variables.



Now paste this path here.



Step 11

Then we create a default directory where MongoDB will save all its data. For this open a command prompt and execute the following command.



Now you will find that the folder named data has been created in your C: directory, this folder contains another folder whose name is db. So far the db folder is empty. In the future all the data and the database will be stored here.

After all the preceding tasks we run the MongoDB server and client. First close the opened Command Prompt and open it again.

First run the “mongod” command . When you run this command the system will show many messages.



The MongoDB command is used to run a server at a specific port number. By default this port number is 27017.

Now again go to the C:\data\db directory. You will find that some files and folders have been created automatically. All these files are generated by Mongod. Each file and folder has a specific task and use.



Open another command prompt window and run the mongo command.



The Mongo command is use to start a client. If you watch the previous command prompt (in which we ran the MongoDB command) you will find the following message:



This message shows that the number of active clients is one. If you open another command prompt and run the mongo command then you will find that the number of opened connection is two.



The installation and configuration has been completed.

Today we learned how to install MondoDB in Windows. The next articles will start working on MongoDB. Until then keep coding.
