##Download MongoDB

There are three builds of MongoDB for Windows:

1) MongoDB for Windows Server 2008 R2 edition [Download link]

2) MongoDB for Windows 64-bit [Download link]

3) MongoDB for Windows 32-bit [Download link]

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

c:\> wmic os get osarchitecture

More download options are given in official website of MongoDB.

##Install MongoDB

The given links above will download zip files which you extract directly onto any place in your system of your choice. I have extracted them in “d:/mongodb“. So, all code samples will in this post as well as future posts will refer to this location.

It’s recommended to add d:/mongodb/bin to Windows environment variable, so that you can access the MongoDB’s commands in command prompt directly.

Also, please create following directories inside d:/mongodb

  • D:\mongodb\data
  • D:\mongodb\log

##Create mongo.config Configuration File

This is important step before marching ahead. Create a normal text file in location d:/mongodb and save it with name mongo.config.

Now place the below configuration options in file. You can change the option’s values at your will.

To start the MongoDB server, use below command in command prompt:

##MongoDB Windows Service

To install the window service, use below command:

mongod –config D:\mongodb\mongo.config –install

Start the windows service from command prompt:

net start MongoDB

Stop the windows service from command prompt:

##Download/Use MongoDB Java Driver

Download the MongoDB java driver (mongo-java-driver-2.9.3.jar) from this download link. It’s a jar file you need to include in your classpath/ copy in lib folder in project where you want to use MongoDB.

##Verify MongoDB Installation

To verify that MongoDB has been installed and working properly, execute below program:

package examples.mongodb.install;
 
import java.net.UnknownHostException;
import java.util.List;
 
import com.mongodb.MongoClient;
 
public class VerifyMongoDBInstallation {
    public static void main(String[] args) throws UnknownHostException {
        MongoClient mongo = new MongoClient("localhost", 27017);
 
        List<String> dbs = mongo.getDatabaseNames();
        for (String db : dbs) {
            System.out.println(db);
        }
    }
}
 
Output:
 
local
admin

That’s all for MongoDB installation, startup and shutdown operations. Next, we will learn about some CRUD operations. Follow me to stay tuned.

Happy Learning !!
