[Use it like this!] Configuration and utilization of Django development environment on the Naver Cloud Platform [1]
* This content was created by Changan Song, a Naver Cloud Platform Tech Evangelist.
Greetings, this is Naver Cloud Platform.
Python, a development language that’s highly favored since it’s easy to learn and can be used in many fields!
Among them, Python-based Django is a web framework that allows you to develop websites quickly and easily.
In this post, I’ll talk about how to build a Django development environment using a server on the Naver Cloud Platform.
* There’ll be 2 episodes about this topic, so look forward to the next post.
Before we get started…
Q. What is Django?
Django is a free open-source web application framework created with Python. It is a web framework made up of components that help you develop a website quickly and easily. Django allows you to use a number of Python libraries, and it’s fast and easy to develop by using Python syntax.
Server creation and package installation
0. Creating a server of the Naver Cloud Platform
<manual Link>
The post below includes a guide for interworking with a DNS and public IP on Naver Cloud Platform.
(Link) Linkage with the Naver Cloud Platform’s DNS service, Server service, and public IP service
1. Install the Python package, pip-related Python package, and Python setuptools on the created server.
yum update python -y
yum install python-setuptools
curl -k -O https://bootstrap.pypa.io/get-pip.py
python get-pip.py2. Install Django-related Python package.
pip install DjangoDEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won’t be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

3. Enter print (django.get_version()) in the command shell as shown below to check the Django version. Also, make sure that the current version is 1.11.26.
# python
Python 2.7.5 (default, Aug 7 2019, 00:51:29)
[GCC 4.8.5 20150623 (Red Hat 4.8.5–39)] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import django
>>> print(django.get_version())
1.11.264. Install MariaDB on the host to connect Django and MariaDB. Activates and starts the daemon on bootup (Django’s default setting is SQLite).
yum install -y mariadb mariadb-server mariadb-devel
systemctl enable mariadb.service
systemctl start mariadb.service5. Install MySQL-related Python package.
pip install mysql-pythonDEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won’t be maintained after that date.

6. Start a new Django project. In the current example, it will be specified as dasvader.
django-admin.py startproject dasvader7. The new project will proceed with a basic setup in dasvader.
In the example, the list allowed when linking dasvader with MariaDB and accessing it from an external environment will be designated.
vim dasvader/settings.py…DATABASES = {
‘default’: {
‘ENGINE’: ‘django.db.backends.mysql’,
‘NAME’: ‘djangotest’,
‘USER’: ‘csong’,
‘PASSWORD’: ‘djangotest’,
‘HOST’: ‘’,
‘PORT’: ‘’,
}
}DATABASE_OPTIONS = {‘charset’: ‘utf8’}
LANGUAGE_CODE = ‘ko-kr’
TIME_ZONE = ‘Asia/Seoul’….
ALLOWED_HOSTS = [“example.csong.kr”,”106.10.40.78"]
8. After the setup is complete, begin syncing dasvader with the database through the “python manage.py migrate” command.
python manage.py migrateSystem check identified some issues:
WARNINGS:
?: (mysql.W002) MySQL Strict Mode is not set for database connection ‘default’
HINT: MySQL’s Strict Mode fixes many data integrity problems in MySQL, such as data truncation upon insertion, by escalating warnings into errors. It is strongly recommended you activate it. See: https://docs.djangoproject.com/en/1.11/ref/databases/#mysql-sql-mode
Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
Applying contenttypes.0001_initial… OK
Applying auth.0001_initial… OK
Applying admin.0001_initial… OK
Applying admin.0002_logentry_remove_auto_add… OK
Applying contenttypes.0002_remove_content_type_name… OK
Applying auth.0002_alter_permission_name_max_length… OK
Applying auth.0003_alter_user_email_max_length… OK
Applying auth.0004_alter_user_username_opts… OK
Applying auth.0005_alter_user_last_login_null… OK
Applying auth.0006_require_contenttypes_0002… OK
Applying auth.0007_alter_validators_add_error_messages… OK
Applying auth.0008_alter_user_username_max_length… OK
Applying sessions.0001_initial… OK
9. Create users in the project and designate them to access the admin page.
python manage.py createsuperuser
Username (leave blank to use ‘root’): admin
Email address: admin@csong.kr
Password: test1111
Password (again): test1111
Superuser created successfully.10. Run the project on the current test server and make it accessible from an external environment.
python manage.py runserver 0.0.0.0:800011. After connecting the executed server at http://example.csong.kr:8000/ from an external environment, you can see that the new page can be accessed normally.

Before we go…
In this post, we learned how to create a server through the Naver Cloud Platform services, as well as how to install and configure Django-related packages on the server.
In the next post, we’ll learn how to build a REST API server using Django.
We’ll be back with more useful content in the future. Thank you.
