Configure the Python connection Redis:

1. Install the Redis python package:

Use Easy-install installation, about the configuration of Easy-install, refer to the above Python environment to build.

--Install parser package (optional)

Description: Parser can control how the content of the Redis response is parsed. Redis-py contains two parser classes, Pythonparser and Hiredisparser. By default, if the Hiredis module is already installed, Redis-py will use Hiredisparser, or pythonparser will be used.

Hiredisparser is written in C, by the Redis core team maintenance, performance than pythonparser to improve more than 10 times times, so recommended use. Installation method, using Easy_install:
