NoSQL Database-MongoDB

Finally determined to buy in some East "Python core programming (ii)" and "Bird Brother Linux, Basic (iii)". It feels like learning Linux is better at first or in a virtual machine, so install VirtualBox and download the cent OS 7. Install cent OS found completely no GUI Ah, fortunately, before using a period of time Ubuntu, feel okay.

(i) installation under the Windows system

(1) Download, the official website is http://www.mongodb.org/do not go to the COM that. Download the 2.4 stable version.

(2) Download the zip file and unzip it. Create a new MongoDB on the D drive and move the extracted files to MongoDB. You then create a new data and logs in the MongoDB folder, which you can use to place the file and the log file separately.

(3) Open cmd and run the following command to start the MongoDB service.

Mongo.exe is the MongoDB interactive shell

(4) It is inconvenient to start the service so that the MongoDB service can be set as Windows system service

D:\mongodb\bin>mongod--logpath d:/mongodb/logs/mongodb.log--logappend--dbpath D:/mongodb/data--directoryperdb --servicename MongoDB--install

This allows the MongoDB service to be found in the Windows service.

net start MongoDB # Start service net stop MongoDB # Shutdown Service net Restart MongoDB # Restart Service

This is the basic installation, detailed configuration and use or need to look at the official documents and other materials.

Official Document: HTTP://DOCS.MONGODB.ORG/V2.4/

A simple code: (Need to install Pymongo module)

#!coding=utf-8import pymongo# establishes the connection con = Pymongo. Connection (' 127.0.0.1 ', 27017) # CREATE DATABASE MyDB = con.mydb# Add user mydb.add_user (' Test ', ' Test ') # User authentication mydb.authenticate (' test ') , ' Test ') # Create data table Muser = mydb.user# Insert a record Muser.save ({' id ': 1, ' name ': ' Test '}) Muser.insert ({' id ': 2, ' name ': ' Hello '}) # query A record # print muser.find_one () # for U in Muser.find (): # Print Ufor u in Muser.find ().
