Install MongoDB on Windows

Overview

Use this tutorial to install MongoDB on a Windows systems.

Platform Support

Starting in version 2.2, MongoDB does not support Windows XP. Please use a more recent version of Windows to use more recent releases of MongoDB.

Important

If you are running any edition of Windows Server 2008 R2 or Windows 7, please install a hotfix to resolve an issue with memory mapped files on Windows.

Requirements

On Windows MongoDB requires Windows Server 2008 R2, Windows Vista, or later. The MSI installer includes all other software dependencies.

Install MongoDB

1

Determine which MongoDB build you need.

There are three builds of MongoDB for Windows:

MongoDB for Windows 64-bit runs only on Windows Server 2008 R2, Windows 7 64-bit, and newer versions of Windows. This build takes advantage of recent enhancements to the Windows Platform and cannot operate on older versions of Windows.

MongoDB for Windows 32-bit runs on any 32-bit version of Windows newer than Windows Vista. 32-bit versions of MongoDB are only intended for older systems and for use in testing and development systems. 32-bit versions of MongoDB only support databases smaller than 2GB.

MongoDB for Windows 64-bit Legacy runs on Windows Vista, Windows Server 2003, and Windows Server 2008 and does not include recent performance enhancements.

To find which version of Windows you are running, enter the following command in the Command Prompt:

wmic os get osarchitecture
2

Download MongoDB for Windows.

Download the latest production release of MongoDB from the MongoDB downloads page. Ensure you download the correct version of MongoDB for your Windows system. The 64-bit versions of MongoDB does not work with 32-bit Windows.

3

Install the downloaded file.

In Windows Explorer, locate the downloaded MongoDB msi file, which typically is located in the default Downloads folder. Double-click the msi file. A set of screens will appear to guide you through the installation process.

You may specify an installation directory if you choose the “Custom” installation option. These instructions assume that you have installed MongoDB to C:\mongodb.

MongoDB is self-contained and does not have any other system dependencies. You can run MongoDB from any folder you choose. You may install MongoDB in any folder (e.g. D:\test\mongodb)

Run MongoDB

Warning

Do not make mongod.exe visible on public networks without running in “Secure Mode” with the auth setting. MongoDB is designed to be run in trusted environments, and the database does not enable “Secure Mode” by default.

1

Set up the MongoDB environment.

MongoDB requires a data directory to store all data. MongoDB’s default data directory path is \data\db. Create this folder using the following commands from a Command Prompt:

md \data\db

You can specify an alternate path for data files using the --dbpath option to mongod.exe, for example:

C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data

If your path includes spaces, enclose the entire path in double quotes, for example:

C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"

You may also specify the dbpath in a configuration file.

2

Start MongoDB.

To start MongoDB, run mongod.exe. For example, from the Command Prompt:

C:\mongodb\bin\mongod.exe

This starts the main MongoDB database process. The waiting for connections message in the console output indicates that the mongod.exe process is running successfully.

Depending on the security level of your system, Windows may pop up a Security Alert dialog box about blocking “some features” of C:\mongodb\bin\mongod.exe from communicating on networks. All users should select Private Networks, such as my home or work network and click Allow access. For additional information on security and MongoDB, please see the Security Documentation.

3

Connect to MongoDB.

To connect to MongoDB through the mongo.exe shell, open another Command Prompt.

C:\mongodb\bin\mongo.exe

If you want to develop applications using .NET, see the documentation of C# and MongoDB for more information.

4

Begin using MongoDB.

To begin using MongoDB, see Getting Started with MongoDB. Also consider the Production Notes document before deploying MongoDB in a production environment.

Later, to stop MongoDB, press Control+C in the terminal where the mongod instance is running.

Configure a Windows Service for MongoDB

1

Configure directories and files.

Create a configuration file and a directory path for MongoDB log output (logpath):

Create a specific directory for MongoDB log files:

md "C:\mongodb\log"

In the Command Prompt, create a configuration file for the logpath option for MongoDB:

echo logpath=C:\mongodb\log\mongo.log > "C:\mongodb\mongod.cfg"
2

Run the MongoDB service.

Run all of the following commands in Command Prompt with “Administrative Privileges:”

Install the MongoDB service. For --install to succeed, you must specify the logpath run-time option.

"C:\mongodb\bin\mongod.exe" --config "C:\mongodb\mongod.cfg" --install

Modify the path to the mongod.cfg file as needed.

To use an alternate dbpath, specify the path in the configuration file (e.g. C:\mongodb\mongod.cfg) or on the command line with the --dbpath option.

If the dbpath directory does not exist, mongod.exe will not start. The default value for dbpath is \data\db.

If needed, you can install services for multiple instances of mongod.exe or mongos.exe. Install each service with a unique --serviceName and --serviceDisplayName. Use multiple instances only when sufficient system resources exist and your system design requires it.

3

Stop or remove the MongoDB service as needed.

To stop the MongoDB service use the following command:

net stop MongoDB

To remove the MongoDB service use the following command:

"C:\mongodb\bin\mongod.exe" --remove
