Django&MySQL environment deployment under Ubuntu 14.04

Python environment setup##

Operating system Ubuntu14.04, comes with Python2.7.6

im@58user:/$ python
Python 2.7.6(default, Oct 262016,20:30:19)[GCC 4.8.4] on linux2
Type "help","copyright","credits" or "license"for more information.>>>

Django environment setup ##

The current version of Django has reached 1.11. Go to the official website to download the file corresponding to Linux, then unzip & install. (Official website download address)

tar xzvf Django-1.11.x.tar.gz
cd Django-1.11.x
sudo python setup.py install

At this time, it may prompt ImportError: No module named setuptools

Execute sudo https://bootstrap.pypa.io/ez_setup.py -O-| sudo python

Then execute sudo python setyp.py install

So far, Django is installed successfully~!

MysqlInstall##

Execute the following command, you may need to enter the root password and confirm it during operation.

sudo apt-get install mysql-server mysql-client
sudo apt-get install libmysqld-dev

Then link MySQL and Python

sudo apt-get install python-dev
sudo wget https://pypi.python.org/packages/source/M/MySQL-python/MySQL-python-1.2.5.zip
unzip MySQL-python-1.2.5.zip
cd MySQL-python-1.2.5/
sudo python setup.py install

The way to enter the mysql database:

• sudo mysql
• mysql -u root -p
  Then enter the password

Set the root password for mysql: ####

First enter mysql in the first way

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with-A

Database changed
mysql> update user set Password =PASSWORD('root') where User ='root';
Query OK,3 rows affected(0.00 sec)
Rows matched:3  Changed:3  Warnings:0
mysql> exit
In brackets'root'Is the new password

New Project##

Time to verify the results
Switch the current directory to Python's Worspace, and enter the new project name:

im@58user:~/PythonProjects$django-admin.py startproject Hello
im@58user:~/PythonProjects$ cd Hello/
im@58user:~/PythonProjects/Hello$ tree
├── Hello
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── manage.py

• init.py: Python feature, it can be an empty file, indicating that this folder is a package that can be imported.
• settings.py: configuration file. This article mainly modifies database information, template directory, and load module information.
• url.py: URL configuration file, which specifies the mapping relationship between functions and URLs.
• wsgi.py: Not used in this article, but used when nginx/apache+wsgi is running Django in a production environment

Next we write a HelloWorld page.
Create a views.py file in the first level directory under the Hello file

im@58user:~/PythonProjects/Hello$ touch views.py
im@58user:~/PythonProjects/Hello$ ls
Hello  manage.py  views.py
im@58user:~/PythonProjects/Hello$ tree
.
├── Hello
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
├── manage.py
└── views.py

1 directory,6 files

Write the following code in the views.py file

from django.http import HttpResponse

def hello(request):returnHttpResponse("Hello World~!~!")

Then add the path to the urls.py file

from django.conf.urls import url
from django.contrib import admin
from views import hello

urlpatterns =[url(r'^admin/', admin.site.urls),url(r'^hello/', hello),]

Then execute in the Hello directory```python manage.py runserver 0.0.0.0:8080

Open the browser and visit http://127.0.0.1:8000/hello/ to see the display results.
