### uWSGIとは？
-WSGIは仕様で、uWSGIは既存のWebサーバに機能を追加
-WebサーバにNginx, WSGIコンテナにuWSGI(Nginxとは別プロセス)
-Apache2, Nginx, cherokee, lighttpdに対応
-gunicornというWSGIも有名
-Apacheは同時接続数が極端に多くなると対応できないが、Nginxはレスポンスが早い

### Django構築
$ django-admin startproject testSite
$ python3 manage.py startapp testapp

settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'testapp',
]
ALLOWED_HOSTS = ['*']

views.py

from django.http import HttpResponse
# Create your views here.

def hello(request):
	return HttpResponse("hello, Nginx!")

urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.hello, name='hello'),
]

urlpatterns = [
    path('admin/', admin.site.urls),
    path('testapp/', include('testapp.urls')),
]

### UbuntuにNginx
$ sudo apt update
$ apt show nginx
Package: nginx
Version: 1.18.0-0ubuntu1
$ sudo apt install nginx
$ nginx -v

### djangoでuWSGI
$ python3 manage.py runserver 192.168.33.10:8000

$ uwsgi –http :8000 –module testSite.wsgi

testApp/uwsgi_params
