MongoDB Installation (window) and Java Connection test

Download the 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 input and enter: D:

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

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

Note: Here is the directory where the specified data is stored, the default port number of MongoDB is 27017, the browser input 127.0.0.1:27017 is prompted to start successfully, close the CMD window will exit the program

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

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

Input and then enter: MONGO

This is the command line interface of the database,

Enter exit or CTRL + C to exit.

when Mongod.exe is closed, Mongo.exe cannot connect to the database, so every time you want to use a MongoDB database, you need to open Mongod.exe Process Order, so the trouble is, we install the window service

Fourth step: Install as a service

Continue in cmd input: 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 "this will cause a service called MongoDB in the window service to be more convenient.
Here is the test I used to connect MongoDB with JavaNote The driver package that references MongoDB
