Django framework (1): installation and deployment

As the most popular Web framework in Python, Django is trying to deploy it today. Like other frameworks, we mainly learn their naming rules and APIs. To use a network framework. You must be familiar with Python before using Django.

Django installation:

I chose to install it from the source code, and get the source code through GitHub for installation.

     git clone https://github.com/django/django.git

Root permission:

Python setup. py install

Next, check whether Django is successfully installed.

import djangodjango.VERSION

Output:

(1, 6, 0, 'alpha', 0)

Install a database: Django Web applications generally require a database to support, and a database driver needs to be installed before using the database. Supports the following four types of databases: PostgreSQL (http://www.postgresql.org) sqlite3 (http://www.aqlite.org) MySQL (http://www.mysql.com) Oracle (http://www.oracle.com) is now more mainstream database MySQL, prior to contact SQLite more lightweight database, this is the most advanced development environment for MySQL. Install MySQL from the source, and set the root password after installation.

 mysqladmin -uroot -p -h localhost password passwd

If necessary, you can modify/etc/MySQL/My. CNF to configure MySQL.
Then start MYSQL:

lrqrun@lrqrun:/etc/init.d/mysql start

Test whether the installation is successful:

lrqrun@lrqrun:~/work/Django$ mysql -uroot -pEnter password: Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 39Server version: 5.5.28-0ubuntu0.12.04.3 (Ubuntu)Copyright (c) 2000, 2012, Oracle and/or its affiliates.

Deployment of DJANGO: Create your working directory:/home/username/djcode to the directory you created, run the command django-admin.py startproject mysite to create a directory named mysite under your current directory that contains the following files: mysite/manage. PY mysite/_ init __. PY settings. PY URLs. PY wsgi. PY * _ init __. PY: Let Python treat this directory as a file required by an Development Kit (that is, a module. This is an empty file. You do not need to modify it. * Manage. py: a command line tool that allows you to interact with this Django project in multiple ways. Type python manage. py help to see what it can do. You do not need to edit this file.

Usage: manage.py subcommand [options] [args]Options:  -v VERBOSITY, --verbosity=VERBOSITY                        Verbosity level; 0=minimal output, 1=normal output,                        2=verbose output, 3=very verbose output  --settings=SETTINGS   The Python path to a settings module, e.g.                        "myproject.settings.main".

* Settings. py: settings or configurations of this Django project. View and understand the available setting types and their default values in this file. * URLs. py: Set the URL of the Django project. It can be viewed as the directory of your Django website. Currently, it is empty. * Wsgi: configuration file of the wsgi web service framework of the Django project. Run the development server: Run Python manage. py runserver in the current directory to start the server. By default, the runserver command starts the development server on port 8000 and only listens to local connections. To change the server port, you can pass the port as a command line parameter: Python manage. py runserver 8080
