1) 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]

2) 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.

Also, please create following directories inside d:/mongodb

• D:\mongodb\data
• D:\mongodb\log

3) Create mongo.config Configuration File

his is important step before marching ahead. Create a normal text file in location d:/mongodb and save it with namemongo.config.
Now place the below configuration options in file. You can change the option’s values at your will.

##Which IP address(es) mongod should bind to. bind_ip = 127.0.0.1   ##Which port mongod should bind to. port = 27017   ##I set this to true, so that only critical events and errors are logged. quiet = true   ##store data here dbpath=D:\mongodb\data    ##The path to the log file to which mongod should write its log messages. logpath=D:\mongodb\log\mongo.log   ##I set this to true so that the log is not overwritten upon restart of mongod. logappend = true    ##log read and write operations diaglog=3   ##It ensures write durability and data consistency much as any journaling scheme would be expected to do. ##Only set this to false if you don’t really care about your data (or more so, the loss of it). journal = true

4) Start/Shutdown the MongoDB Server

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

mongod.exe --config d:\mongodb\mongo.config

1 2 3 4

D:\mongodb\bin>mongod --config D:\mongodb\mongo.config --journal 2014-05-25T16:51:18.433+0530 warning: --diaglog is deprecated and will be removed in a future release 2014-05-25T16:51:18.434+0530 diagLogging level=3 2014-05-25T16:51:18.435+0530 diagLogging using file D:\mongodb\data/diaglog.5381d22e

To connect to MongoDB from command prompt, use below command:

d:\mongodb\bin>mongo

1 2 3 4 5 6 7 8 9 10 11 12 13 14

D:\mongodb\bin>mongo MongoDB shell version: 2.6.1 connecting to: test Welcome to the MongoDB shell. For interactive help, type "help". For more comprehensive documentation, see   http://docs.mongodb.org/ Questions? Try the support group   http://groups.google.com/group/mongodb-user Server has startup warnings: 2014-05-25T16:52:09.158+0530 [initandlisten] 2014-05-25T16:52:09.158+0530 [initandlisten] ** NOTE: This is a 32 bit MongoDB binary. 2014-05-25T16:52:09.158+0530 [initandlisten] **       32 bit builds are limited to less than 2GB of data (or less with --jour nal). 2014-05-25T16:52:09.158+0530 [initandlisten] **       See http://dochub.mongodb.org/core/32bit 2014-05-25T16:52:09.158+0530 [initandlisten]

To shutdown the MongoDB server, you must be authorized user. So after getting auth complete, use below command in command prompt:

db.shutdownServer()

5) 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:

net stop MongoDB

Remove the windows service

mongod --remove

Sample run of all above four commands is below:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Please use --journal if you wa nt durability. 2014-05-25T20:09:32.515+0530 2014-05-25T20:09:32.518+0530 Trying to remove Windows service 'MongoDB' 2014-05-25T20:09:32.520+0530 Service 'MongoDB' removed   D:\mongodb\bin>

6) 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.

7) Verify MongoDB Installation

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

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
