Then, run this installation file, follow the prompts to install, there is a need to choose, because it is basic use, so the installation type is selected . Last point finish

Next is the opening and use of the MongoDB service, said here, I naturally think that may be in the mongodb installation in the Windows Service there to register a mongodb Service, the results of a look, no, this is a lost. So how do you start the service?

This mongoDB service side and client side is a few exe files, and put together. Turn on the service to open it.

First specify MongoDB Data folder, set up MongoDB data Folders on D disk:d:\ Mongo\data

Then go to the bin directory of the MongoDB home and tap the following command:

Mongod.exe--dbpath D:\mongodb\data

Note If your data file has spaces, enclose the path with double quotation marks

If you see a similar interface below, it means that the service has been successfully opened.

> DB

MyDB

> K={x:3}

{"X": 3}

> Db.mydb.insert (k)

Writeresult ({"ninserted": 1})

>

So the insertion is successful.

then show collections;

The current database and index are displayed

> Show Collections;

MyDB

System.indexes

Find data

> Db.mydb.find ()

{"_id": ObjectId ("53eb58a53a8f3927b8de97a0"), "name": "MONGO"}

{"_id": ObjectId ("53eb6681051885f61818992a"), "X": 3}
