エックスサーバでPythonによるWebサービスを行う手順について説明します。
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
１,X-serverでサービスを取得する
２,brewをインストール
３,python3.8をインストール
４,Djangoをインストール
５,プロジェクトを作成
６,Webから接続
７,アプリを追加
８,AdminのCSSを有効にする
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
 
1,X-serverでサービスを取得する
 
https://www.xserver.ne.jp/
 
はじめにサーバIDを分かりやすい名前を決めて
 
xxxxxxxxをサーバIDに置き換えてください
 
chmod 600 xxxxxxxx.key
ssh -l xxxxxxxx -i xxxxxxxx.key xxxxxxxx.xsrv.jp -p 10022
 
cat /etc/redhat-release
python -V
python3 -V
 
２,brewをインストール
sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
 
echo 'eval $(/home/xxxxxxxx/.linuxbrew/bin/brew shellenv)' >>~/.profile
eval $(/home/xxxxxxxx/.linuxbrew/bin/brew shellenv)
 
source ~/.profile
 
brew install gcc
brew doctor
 
python -V
python3 -V
 
３，python3.8をインストール
brew install python3
 
python -V
python3 -V
 
python3 -m venv env
source env/bin/activate
python　-V
 
４，Djangopyをインストール
pip install --upgrade pip
pip install django==1.11.17
 
python -m django --version
 
cd
pwd
 
５,プロジェクトを作成
django-admin startproject mysite
 
ls
cd mysite
 
python manage.py migrate
python manage.py createsuperuser
 
６,Webから接続
cd
cd xxxxxxxx.xsrv.jp
cd public_html
 
vi test.html
 
<html>
<hr>
good!!
<hr>
</html>
 
http://xxxxxxxx.xsrv.jp/test.html
 
mkdir top
cd top
 
ls /home/xxxxxxxx/.linuxbrew/bin/python*
 
※インストールされたpythonのバージョンにあわせ
　以下の必要な場合はCGI内のパスを変更してください
 
vi mysite.cgi
i
 
------------
#!/home/xxxxxxxx/.linuxbrew/bin/python3.8
 
# encoding: utf-8
 
import os, sys
 
sys.path.append("/home/xxxxxxxx/env/lib/python3.8/site-packages")
sys.path.append("/home/xxxxxxxx/env/lib/python3.8/site-packages/django")
 
sys.path.append("/home/xxxxxxxx/mysite/")
 
def run_with_cgi(application):
 
    environ                      = dict(os.environ.items())
    environ['wsgi.input']        = sys.stdin.buffer
    environ['wsgi.errors']       = sys.stderr.buffer
    environ['wsgi.version']      = (1,0)
    environ['wsgi.multithread']  = False
    environ['wsgi.multiprocess'] = True
    environ['wsgi.run_once']     = True
    environ['PATH_INFO']         = environ.get('PATH_INFO',"/") # 追加
 
 
    if environ.get('HTTPS','off') in ('on','1'):
        environ['wsgi.url_scheme'] = 'https'
    else:
        environ['wsgi.url_scheme'] = 'http'
 
    headers_set  = []
    headers_sent = []
 
    def write(data):
        if not headers_set:
             raise AssertionError("write() before start_response()")
 
        elif not headers_sent:
             # Before the first output, send the stored headers
             status, response_headers = headers_sent[:] = headers_set
             sys.stdout.buffer.write(('Status: %s\r\n' % status).encode("ascii"))
             for header in response_headers:
                 sys.stdout.buffer.write(('%s: %s\r\n' % header).encode("ascii"))
             sys.stdout.buffer.write(('\r\n').encode("ascii"))
 
        sys.stdout.buffer.write(data)
        sys.stdout.buffer.flush()
 
    def start_response(status,response_headers,exc_info=None):
        if exc_info:
            try:
                if headers_sent:
                    # Re-raise original exception if headers sent
                    raise exc_info[0](exc_info[1]).with_traceback(exc_info[2])
            finally:
                exc_info = None     # avoid dangling circular ref
        elif headers_set:
            raise AssertionError("Headers already set!")
 
        headers_set[:] = [status,response_headers]
        return write
 
    result = application(environ, start_response)
    try:
        for data in result:
            if data:    # don't send headers until body appears
                write(data)
        if not headers_sent:
            write('')   # send headers now if body was empty
    finally:
        if hasattr(result,'close'):
            result.close()
 
# Change to the name of your settings module
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
 
from django.core.wsgi import get_wsgi_application
run_with_cgi(get_wsgi_application())
-------
 
vi .htaccess
 
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ mysite.cgi/$1 [QSA,L]
 
chmod 755 mysite.cgi
chmod 604 .htaccess
 
http://xxxxxxxx.xsrv.jp/top
 
cd
cd mysite
cd mysite
 
vi settings.py
 
ALLOWED_HOSTS = []
ALLOWED_HOSTS = ['*']
 
http://xxxxxxxx.xsrv.jp/top
 
http://xxxxxxxx.xsrv.jp/top/admin
 
７,アプリを追加
 
cd ../
python manage.py startapp polls
 
cd polls
 
vi views.py
from django.http import HttpResponse
 
 
def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")
 
---
vi urls.py
 
from django.conf.urls import url
 
from . import views
 
urlpatterns = [
    url(r'^$', views.index, name='index'),
]
 
cd ../
cd mysite
vi urls.py
 
from django.conf.urls import include
 
    url(r'^polls/', include('polls.urls', namespace='polls')),
 
vi settings.py
 
INSTALLED_APPS = [
 
    'polls',
]
 
８，AdminのCSSを有効にする
vi settings.py
 
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.10/howto/static-files/
 
#STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATIC_URL = './static/'
 
vi urls.py
----
from django.conf import settings
from django.conf.urls.static import static
from django.views.static import serve
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^admin/([a-xA-Z0-9_]*/)*static/(?P<path>.*)$', serve, {'document_root': settings.STATIC_ROOT}),
]
 
cd ../
python manage.py collectstatic
 
vi settings.py
 
LANGUAGE_CODE = 'en-us'
LANGUAGE_CODE = 'ja'
