Python Connection Redis Connection configuration

System environment:

Os:oracle Linux Enterprise 5.6

redis:redis-2.6.8

python:python-2.7.3

Python package version of Redis: Redis-2.7.2.tar

Prerequisites:

1. Ensure that Redis has been successfully installed and configured correctly, refer to the documentation

2. Ensure that the Python environment is configured successfully, refer to the documentation

To configure Python to connect to Redis:

1. Install the Redis python package:

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

--Install the parser package (optional)

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

Hiredisparser is written in C, and is maintained by the Redis core team, with performance up to 10 times times higher than pythonparser, so it is recommended. Installation method, using Easy_install:

[Root@njdyw ~]# easy_install2.7.3 Hiredis
