How do I stop cassandra server running on a single node in my mac os x? Cassandra script doesn't have -stop option. Only way other than restart the mac os x, was to do a 'ps' and find the java pro. If you use Mac OS X as your platform for development work, then you may be interested to know how easy it is to use Apache Cassandra on the Mac. The following shows you how to download and setup Cassandra, its utilities, and also use DataStax OpsCenter, which is a browser-based, visual management and monitoring tool for Cassandra. Download the Software DataStax makes available the DataStax. Cassandra is a useful NoSQL database management system with praise for its high availability. Let's demonstrate how to install Cassandra 2.1 on Mac OS X. Step 1) Install the Oracle Java Development Kit (JDK) On Macs, you can easily download the corresponding dmg file and install. After installing, check that you have installed the JDK.

Django is a Python web server while Cassandra is a high availability database. This article will be a complete guide for installation and use of Django with Cassandra.
Django InstallationInstalling PythonSince Django is a Python web server, you'll need Python. You can check if you have Python already.
However, if you're using a Mac, I have had a lot of problems with the default system Python with the combination of Cassandra and Django. I would recommend reinstalling a new version of Python.
If you don't have the Python version that you want, downloads are available at:
Various versions of Django are only compatible with different versions of Python. Currently, Django version 1.8 is the stable version release.
After you have obtained Python, you will need pip (which is a Python package installer).
To get pip, you will need to download the following file:
After download the get-pip.py file, you can install pip by changing directory to the download location.
After you have pip, you can install Django and the django cassandra driver.
Installing CassandraNow that you have Django and the Django's Cassandra library, you have to install Cassandra of course. I've written another blog post about installing and setting up Cassandra.
Setting up a new Django projectWe will create a Django project in the folder that we are at.
A new folder called mysite/ will be created with the Django files.
INSTALLED_APPS = ('django_cassandra_engine',) + INSTALLED_APPS
INSTALLED_APPS=('django_cassandra_engine',)+INSTALLED_APPS

This app should be the first app on INSTALLED_APPS list.
Also, you need to change another group of lines.

You can also change the names of <code>NAME</code> and <code>TEST_NAME</code>.</p><p>After we have configured the settings, we can create an application where our website will render. The application is another folder with Python files that will render our Django website.</p><p>The following directory structure is created inside the top level <code>mysite/</code> folder:</p><div><textarea readonly='>example/ __init__.py admin.py migrations/ __init__.py models.py tests.py views.py

__init__.py
migrations/
models.py
views.py
Afterwards, you can create a model, which is the schema structure of which objects are saved. Models belong within models.py, which is a file created after we made the application.
We can edit the models.py file inside example/ and include the following as a preliminary model:

from.import views
urlpatterns=[url(r'^$',views.index,name='index'),]
What this snippet does is that it allows a function named index inside example/views.py to render the page at http://localhost:8080.
Inside example/views.py, we can write:
</div><table><tbody><tr><td><div><div>2</div><div>4</div></div></td><td><div><span>return</span><span>HttpResponse</span><span>(</span><span>'Hello world'</span><span>)</span></div></td></tr></tbody></table><p>After saving that file, if you change directory to the top level <code>mysite/</code>, you can run the following command to boot your Django server up.</p><p>If you visit http://localhost:8080, you should see the <code>'Hello world'</code> in plain text.</p><p>Inside the <code>example/views.py</code>, we can start connecting to the Cassandra database with Python. Add the following imports for Cassandra and to the model to be able to establish Python connection with Cassandra.</p><div><textarea readonly='>from cassandra.cqlengine import connectionfrom cassandra.cqlengine.management import sync_tablefrom cassandra.cluster import Clusterfrom models import ExampleModelfrom django.http import HttpResponsedef index(request): cluster = Cluster(['127.0.0.1']) session = cluster.connect() session.set_keyspace('db') insert = ExampleModel(description='Hello world description') insert.save() cluster.shutdown() return HttpResponse('Hello world')

session.set_keyspace('db')
insert=ExampleModel(description='Hello world description')
cluster.shutdown()
Download Cassandra MacMake sure that cassandra -f is running! Visit http://localhost:8080, and the page should render 'Hello world' like before, but this time, it will also insert a row for 'Hello world description' in Cassandra.
In another terminal, you go to the top level mysite/ directory, and run the following command with cassandra -f running in another terminal:
cqlsh:db>; SELECT * FROM ExampleModel;example_id|description----------|-----------|'Hello world description'

example_id|description
|'Hello world description'
You have done your first insert with Django and Cassandra and checked the contents from the Cassandra shell!
