OS: Oracle Linux Enterprise 5.6

Redis: redis-2.6.8

Python: Python-2.7.3

Redis python package version: redis-2.7.2.tar

Prerequisites:

1. make sure that Redis is successfully installed and configured correctly. For more information, see

2. make sure that the Python environment is successfully configured. refer to the documentation.

Configure python to connect to redis:

1. install the Python package of Redis:

Use easy-install for installation. for the configuration of easy-install, refer to the above Python environment.

-- Install the Parser package (optional)

Note: Parser can control how to parse the redis response content. Redis-py contains two Parser classes: PythonParser and HiredisParser. By default, if the hiredis module is installed, redis-py will use HiredisParser; otherwise, PythonParser will be used.

HiredisParser is written in C and maintained by the redis core team. its performance is more than 10 times higher than that of PythonParser. Therefore, it is recommended to use HiredisParser. Installation method, use easy_install:
