MongoDB Installation (window) and Java Connectivity Test

Download Installation First

MongoDB website Download Select window version

The second step is to install

Note The installation directory, my installation directory is D:\Program Files (x86) \mongodb

Step three: Start

Open the cmd window and enter the carriage: D:

Enter and then enter: CD D:\Program Files (x86) \mongodb\server\3.0\bin

Continuation: Mongod-dbpath "D:\Program Files (x86) \mongodb\server\3.0\data\db"

Note: Here is the directory where the specified data is stored, MongoDB's default port number is 27017, the browser input 127.0.0.1:27017 prompted to start successful, close the cmd window will exit the program

New Open a CMD window input and then enter: D:

Enter and then enter: CD D:\Program Files (x86) \mongodb\server\3.0\bin

Enter and then enter: MONGO

This is the command line interface for the database,

Enter exit or CTRL + C to exit.

When the Mongod.exe is closed, Mongo.exe cannot connect to the database, so every time you want to use the MongoDB database to open the Mongod.exe program, so more trouble, we install the window service

Step Fourth: Install as a service

Continue typing in cmd: Mongod--dbpath "D:\Program files (x86) \mongodb\server\3.0\data\db"--logpath "D:\Program Files (x86) \mongodb \server\3.0\data\log\mongodb.log "--install--servicename" MongoDB so that a service named MongoDB would appear in the window service, it would be much more convenient
here is my test with Java connection MongoDB The driver package that references MongoDB
