Is an awesome framework for building lightweight Python web-apps using a minimal amount of boilerplate. This tutorial discusses how to start a new Flask project and how to deploy it on a server. These instructions are tested on Mac OS X 10.8. All code is available under the. Bootstrapping your project One server can host multiple running web applications, and they probably all use different versions of the underlying frameworks. To manage these dependencies, we’ll create a virtual environment where we install the dependencies locally, together with the project instead of globally. In Python, we’ll do this using virtualenv and pip.

These tools provide a clean way to manage the dependencies of different Python projects. Install virtualenv Virtualenv creates the virtual environment. Initializing a virtual environment automatically installs pip as well, which does the Python package installs. We’ll install virtualenv locally, and again on the server. But first, let’s install it on your machine.

Pip freeze > requirements.txt This writes a plain text file that contains the names of the required Python packages and their versions, for example Flask==0.9. We’ll use this file later when we’re setting up our server.

The WSGI script When we’re running our application on a browser, we’ll need a “run script” that tells the server how to setup your application. In other words, the webserver doesn’t run your application directly like we did from the terminal, but uses WSGI to load the application into a separate process. In this WSGI script we can tell the server to use virtualenv to load our setup.

Create a new file called application.wsgi with the following contents. Import os, sys PROJECT_DIR = '/www/helloflask.enigmeta.com/helloflask' activate_this = os.path.join(PROJECT_DIR, 'bin', 'activate_this.py') execfile(activate_this, dict(__file__=activate_this)) sys.path.append(PROJECT_DIR) from helloflask import app as application Note that this file refers to a (non-existent) /www/helloflask.enigmeta.com directory.

We’ll create this directory on the server in a minute. Version your files To make development and deployment easier we should really use version control. Here, we’ll use to manage our files. You should already have a working Git install. At the very least, make sure you’ve configured your full name and email address.

Setup the server In this example we’re using Apache 2 as the web server. We’re going to assume we’re running our app on its own domain or subdomain.

This means we’ll use a virtual host with its own configuration. This is on a virtual private server (VPS), such as from (referral link). Let’s set up the directory structure first.

It will look like this. # Install virtualenv sudo su # You probably need to be root to do this. Apt-get install python-virtualenv # Create the directory structure mkdir -p /www/helloflask.example.org cd /www/helloflask.example.org mkdir logs # Clone the project git clone # Initialize virtualenv and install dependencies virtualenv helloflask cd helloflask pip install -r requirements.txt Here’s a complete template Apache site configuration that can go in /etc/apache2/sites-available/helloflask.example.org (change the last part to reflect your domain).
