Django rest API deploy on apache - django

Question

I have created a django application and deployed it on the server.I have run the application through :-
python manage.py runserver 8000 &
and handle the requests on the apache server through proxy
ProxyPass "/" "http://www.example.com/"
ProxyPassReverse "/" "http://www.example.com/".
But there is a issue that I am facing while testing the api through JMeter, when i am running a test case for 10 users my python service over the server gets killed automatically.
What i am doing wrong or what i have to do more to resolve the above test scenario,please suggest?

Answer 1

First of all you need to deploy it on other server like apache. Below I am sharing how as usual configuration of apache2 to deploy a python django project.
Considering virtual environment is created else see how to create
virtual environment
Apache installation:
You need to install apache if not installed yet. Here I am showing the apache2 installation and some other installation which we need.
sudo apt-get update
sudo apt-get install apache2
sudo a2enmod wsgi
sudo apt-get install python3-pip apache2 libapache2-mod-wsgi-py3
configuration of 000-default.conf file : Generally the apache2 is located on linux m at path /etc/apache2/sites-available/000-default.conf. And the configuration file may like that.
<VirtualHost *:80>
ServerName www.something.com
# this is the document root of your project
DocumentRoot /path/to/my-project
# The directory which you can access with base path EX: www.something.com/static/images/image.png
Alias /static /path/to/my-project/static
<Directory /path/to/my-project/static>
Require all granted
</Directory>
<Directory /path/to/my-project/my-project>
<Files wsgi.py>
Header set Access-Control-Allow-Origin "*"
Require all granted
</Files>
</Directory>
WSGIDaemonProcess my-project python-home=/path/to/my_env python-path=/path/to/my-project
WSGIProcessGroup my-project
WSGIScriptAlias / /path/to/my-project/my-project/wsgi.py
ErrorLog /path/to/my-project/logs/error.log
CustomLog /path/to/my-project/logs/access.log combined3
</VirtualHost>
Django project wsgi.py : The django project you created there have a wsgy.py and this file may look like.
python_home = '/path/to/my_env'
import sys
import site
sys.path.append('/path/to/my-project')
sys.path.append('/path/to/my_env/bin')
sys.path.append('/path/to/my_env/lib/python3.6/site-packages')
# Calculate path to site-packages directory.
python_version = '.'.join(map(str, sys.version_info[:2]))
site_packages = python_home + '/lib/python%s/site-packages' % python_version
# Add the site-packages directory.
site.addsitedir(site_packages)
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "my-project.settings")
application = get_wsgi_application()
After that you can start you apache2 sever sudo service apache2 start
Also you need to give the permission of you project directory sudo chmod -R 777 /path/to/my-project
This is the basic configuration of apache2 with python django project. Hope this will help to configure any linux machine with your python django project

You cannot using python manage.py runserver 8000 on a server, it's for development ONLY.
You can see the documentation here https://docs.djangoproject.com/en/2.1/howto/deployment/wsgi/
A basic conf for Apache would be :
<VirtualHost *:80>
ServerName yoursite.com
ServerAdmin your#site.com
Alias /media/ /path/to/django-app/media/
<Directory /path/to/django-app/media/>
Require all granted
</Directory>
WSGIScriptAlias / /path/to/django-app/conf/wsgi.py
<Directory /path/to/django-app/conf/>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
</VirtualHost>
You need to adapt this for your project.
If you need to install mod_wsgi : https://modwsgi.readthedocs.io/en/develop/user-guides/quick-installation-guide.html
For me i would use https://docs.djangoproject.com/en/2.1/howto/deployment/wsgi/uwsgi/ it's more convenient (pip install uwsgi)
