このドキュメントを読めば、Django をセットアップして、起動することができます。
Django is a Python web framework. See どのバージョンの Python で Django が使えますか? for details.
最新版のPythonを https://www.python.org/downloads/ もしくはOSのパッケージ管理ツールで取得してください。

もし Windows を使っていてこれから Django を始めるなら、 Windows での Django のインストール方法 を読むとよいでしょう。
mod_wsgi
のインストール¶もし単に Django を使って実験したいだけなら、このセクションは飛ばしてください。 Django には軽量 web サーバーが含まれており、テスト用にそれが使えます。本番環境にデプロイするときまで、 Apache をセットアップする必要はありません。
If you want to use Django on a production site, use Apache with mod_wsgi. mod_wsgi operates in one of two modes: embedded mode or daemon mode. In embedded mode, mod_wsgi is similar to mod_perl -- it embeds Python within Apache and loads Python code into memory when the server starts. Code stays in memory throughout the life of an Apache process, which leads to significant performance gains over other server arrangements. In daemon mode, mod_wsgi spawns an independent daemon process that handles requests. The daemon process can run as a different user than the web server, possibly leading to improved security. The daemon process can be restarted without restarting the entire Apache web server, possibly making refreshing your codebase more seamless. Consult the mod_wsgi documentation to determine which mode is right for your setup. Make sure you have Apache installed with the mod_wsgi module activated. Django will work with any version of Apache that supports mod_wsgi.
インストール完了後の mod_wsgi の設定方法に関する情報については、Django を Apache と mod_swgi とともに使うには? を読んでください。
何らかの理由により mod_wsgi が使えなかったとしても、心配はいりません。Django は他にもさまざまな開発オプションをサポートしています。そのうちの一つは uWSGI で、nginx と非常に上手く連携できます。さらに、Django は WSGI の仕様 (PEP 3333) を満たしているので、各種のサーバープラットフォーム上で動作することが保証されています。
DjangoのデータベースAPI機能を使用する場合は、データベースサーバーが実行されていることを確認する必要があります。Djangoは多くの異なるデータベースサーバーをサポートし、PostgreSQL、MariaDB、MySQL、Oracle および SQLite で公式にサポートされています。
If you are developing a small project or something you don't plan to deploy in a production environment, SQLite is generally the best option as it doesn't require running a separate server. However, SQLite has many differences from other databases, so if you are working on something substantial, it's recommended to develop with the same database that you plan on using in production.
公式にサポートされているデータベースの他に、サードパーティ製のバックエンドもあります(これらを使うと、他のデータベースを Django から使えます)。
バックエンドに加えて、 Python のデータベースバインディングをインストールする必要があります。
mysqlclient
. See notes for the MySQL
backend for details.cx_Oracle
の両方について、 Django がサポートするバージョンを確認してください。If you plan to use Django's manage.py migrate
command to automatically
create database tables for your models (after first installing Django and
creating a project), you'll need to ensure that Django has permission to create
and alter tables in the database you're using; if you plan to manually create
the tables, you can grant Django SELECT
, INSERT
, UPDATE
and
DELETE
permissions. After creating a database user with these permissions,
you'll specify the details in your project's settings file, see
DATABASES
for details.

Installation instructions are slightly different depending on whether you're installing a distribution-specific package, downloading the latest official release, or fetching the latest development version.
pip
¶This is the recommended way to install Django.
Install pip. The easiest is to use the standalone pip installer. If your
distribution already has pip
installed, you might need to update it if
it's outdated. If it's outdated, you'll know because installation won't
work.
Take a look at venv. This tool provides isolated Python environments, which are more practical than installing packages systemwide. It also allows installing packages without administrator privileges. The contributing tutorial walks through how to create a virtual environment.
After you've created and activated a virtual environment, enter the command:
$ python -m pip install Django
...\> py -m pip install Django
Check the distribution specific notes to see if your platform/distribution provides official Django packages/installers. Distribution-provided packages will typically allow for automatic installation of dependencies and supported upgrade paths; however, these packages will rarely contain the latest release of Django.
Tracking Django development
If you decide to use the latest development version of Django, you'll want to pay close attention to the development timeline, and you'll want to keep an eye on the release notes for the upcoming release. This will help you stay on top of any new features you might want to use, as well as any changes you'll need to make to your code when updating your copy of Django. (For stable releases, any necessary changes are documented in the release notes.)
If you'd like to be able to update your Django code occasionally with the latest bug fixes and improvements, follow these instructions:
Make sure that you have Git installed and that you can run its commands
from a shell. (Enter git help
at a shell prompt to test this.)
Check out Django's main development branch like so:
$ git clone https://github.com/django/django.git
...\> git clone https://github.com/django/django.git
This will create a directory django
in your current directory.
Make sure that the Python interpreter can load Django's code. The most convenient way to do this is to use a virtual environment and pip. The contributing tutorial walks through how to create a virtual environment.
After setting up and activating the virtual environment, run the following command:
$ python -m pip install -e django/
...\> py -m pip install -e django\
This will make Django's code importable, and will also make the
django-admin
utility command available. In other words, you're all
set!
When you want to update your copy of the Django source code, run the command
git pull
from within the django
directory. When you do this, Git will
download any changes.
