Flask + Apache +wsgi

Colleagues use flask to write some code, need to use Apache run up. Let's record the construction process.

Environment: Ubuntu 12.04

1, install the relevant package:

Apt-get Install Python-flask Libapache2-mod-wsgi

Note: The original flask is required to be installed. (^_^!)

What does Wsgi do?

       wsgi  is a specification of a generic API for mapping between an underlying Web server and a Python Web application. WSGI itself is described by python  pep 0333 . The purpose of the WSGI specification is to provide a common mechanism for hosting a Python Web application on a range of Different Web servers supporting the Python programming language

WSGI is a generic specification interface between webserver and Python Web applications, designed to provide a common mechanism for the deployment of Python programs in different webserver

2. Apache Configuration:

to write a relatively simple

<virtualhost *:80> ServerName what.abc.comdocumentroot/var/www/vpn/wsgiscriptreloading on WSGIScriptAl IAS//VAR/WWW/WHAT/WHAT.WSGI <directory "/var/www/what/" > Order deny,allow allow from all </ Directory></virtualhost>

Note: Here to write a What.wsgi file

The file content is also relatively simple

Import syssys.path.insert (0, '/var/www/what/') from index import app as application

The first two lines if you say that what.wsgi with the script can actually not. "From index import app as application" Here the index is a parameter. See what your application file name is. If index.py here is index

The relationship is about the same as Apache----->wsgi--------->index.py

In addition encountered errors to go to Apache errorlog to find.
