MongoDB installation, open and add, delete, change, check

MongoDB is one of the most popular NoSQL, NoSQL and no only Sql, and the reason I understand it is that it abandons the traditional relational type
The concept of the field type of the database, but instead all of the data is stored in the Key-value way, indexed by the key value.

This article mainly describes the Windows installation and startup of MongoDB, and its basic usage.

One. Installation

1. Download MongoDB, I downloaded the version is Mongodb-win32-i386-2.4.14.zip

2. Unzip the file and there will be a bin folder after decompression

3. Create the relevant file folder where you want to install it, e.g. I install it directly in C:\Program files

4. Create a folder under the C-Drive C:\Program files MongoDB

5. Copy the bin folder to the C:\Program Files\mongodb directory

6. Create the Data folder under this directory and create the DB and log two folders in the data directory

7. Create a MongoDB.log file under the log folder

8. The installation is complete at this point

Two. Start

1. Now open the command line switch to the Bin directory: CD C:\Program Files\mongodb\bin

2. Execute command mongod-dbpath= "C:\Program files\mongodb\data\db"-logpath= "C:\Program files\mongodb\data\log\mongodb.log"

3. Open a new command line window, while keeping the original window does not close, input MONGO can be used for MongoDB interactive page

Note: We can see the following message after the link is successful: 1.mongodb version 2. Connected Database

Three. Simple operation of the database

1. Order show DBS to view altogether several databases

2. Command db to view the current database
