[PYTHON] Deploy the Django tutorial to IIS ①

Introduction

I'll keep a reminder of how I ran the Django tutorial on IIS on Windows 10.

Python installation

Download the installer from the Official Site. When installing, please install for all users. If it is an individual user installation, it cannot be used by IIS users and cannot be operated.

Install PostgreSQL

I want to use PostgreSQL, so I will install it.

Download the installer from the Official Site. This time I installed version 13 of Windows x86-64.

Enable IIS (Internet Information Services)

From Control Panel> Programs> Enable or Disable Windows Features Enable Internet Information Services.

Computer Management> Services and Applications If the Internet information service has been added, it has been enabled.

Django project creation

1. Preparation of development environment

We will create a "web" directory under C: \ Users \ username and work there.

command prompt

C:\Users\username> mkdir web

Install virtualenv

command prompt

C:\Users\username\web> pip install virtualenv

Creating a virtual environment (env)

command prompt

C:\Users\username\web> virtualenv env

Enable virtual environment

command prompt

C:\Users\username\web> env\Scripts\activate

Django installation

command prompt

(env) C:\Users\username\web> pip install Django

wfastcgi installation

command prompt

(env) C:\Users\username\web> pip install wfastcgi

Installation of psycopg2

command prompt

(env) C:\Users\username\web> pip install psycopg2

The result of pip list is below.

command prompt

(env) C:\Users\username\web>pip list
Package    Version
---------- -------
asgiref    3.2.10
Django     3.1.1
pip        20.2.3
psycopg2   2.8.6
pytz       2020.1
setuptools 49.6.0
sqlparse   0.3.1
wfastcgi   3.0.0
wheel      0.35.1

2. Create a project

Follow the Django tutorial to create your project.

command prompt

(env) C:\Users\username\web> django-admin startproject mysite

Check if it works locally

command prompt

(env) C:\Users\username\web>mysite> python manage.py runserver

Go to http://127.0.0.1:8000/ and when the following page is displayed, it's OK.

IIS settings

Add site

Add a new site. From Computer Management> Internet Information Services Set the physical path etc. in Site> Add Website.

The physical path sets the folder for your Django project (parent folder, such as manage.py).

Added Python handler mapping

Set from Handler Mappings> Add Script Map. The executable file specifies python.exe in the env environment.

wfastcgi settings

Unlock to use wfastcgi

(env) C:\Users\username\web\mysite>%windir%\system32\inetsrv\appcmd unlock config -section:system.webServer/handlers
Configuration path"MACHINE/WEBROOT/APPHOST"Section"system.webServer/handlers"Unlocked.

Run wfastcgi enable

(env) C:\Users\username\web\mysite>wfastcgi-enable
Configure configuration changes Commit path"MACHINE/WEBROOT/APPHOST"of"MACHINE/WEBROOT/APPHOST"Section"system.webServer/fastCgi"Applied to
"c:\users\username\web\env\scripts\python.exe|c:\users\username\web\env\lib\site-packages\wfastcgi.py" can now be used as a FastCGI script processor

Create web.config

Create web.config under the Django project (same directory as manage.py). Set the value of scriptProcessor to the value displayed by wfastcgi-enable.

web.config

<configuration>
  <appSettings>
    <add key="WSGI_HANDLER" value="django.core.wsgi.get_wsgi_application()" />
    <add key="PYTHONPATH" value="C:\Users\username\web" />
    <add key="DJANGO_SETTINGS_MODULE" value="mysite.settings" />
  </appSettings>
  <system.webServer>
    <handlers>
        <add name="Python FastCGI" path="*" verb="*" modules="FastCgiModule" scriptProcessor="c:\users\username\web\env\scripts\python.exe|c:\users\username\web\env\lib\site-packages\wfastcgi.py" resourceType="Unspecified" />
    </handlers>
  </system.webServer>
</configuration>

Granting permissions for IIS

Computer Management> Internet Information Services Edit the permissions from My Site (newly created site). Add user [Computer Name \ IIS_IUSRS] on the Security tab

Also, in File Explorer, right-click on the C: \ Users \ username \ web env folder> Properties Also add a user with [Computer name \ IIS_IUSRS].

Operation check

Go to Computer Management> Internet Information Services, select My Site, browse the website and the rocket flies, then the Django site is running.

If you get an error

If you get a 0x800700005 error or a 0x8007010b error as shown below, Please check if the file access permission and the Python.exe path set in the handler mapping are appropriate.

Cause: Occurs when the site directory does not have access to the computer name \ IIS_IUSRS Solution: Add permissions for computer name \ IIS_IUSRS

Cause: Occurs when you do not have access to the computer name \ IIS_IUSRS in the Python.exe directory you are using. Solution: Add permissions for computer name \ IIS_IUSRS

Next time I will write the procedure to change the database to PostgreSQL: wave:
