Python connection to Redis connection Configuration

System Environment: OS: Oracle Linux Enterprise 5.6 redis: redis-2.6.8python: Python-2.7.3redis python package version: redis-2.7.2.tar prerequisites: 1. make sure that Redis is successfully installed and configured correctly. Refer to document 2. make sure that the Python environment has been successfully configured. Refer to the documentation to configure python connection to redis: 1. install the Python package of Redis: use easy-install to install. For the configuration of easy-install, refer to the above Python environment setup.

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.
