Python连接Redis的基本配置方法

在Linux系统下Python连接Redis的基本配置方法具体操作步骤

系统环境：

OS：Oracle Linux Enterprise 5.6

Redis：redis-2.6.8

Python：Python-2.7.3

redis的python包版本：redis-2.7.2.tar

前提条件：

1.确保Redis已成功安装并且正确配置，参考文档

2.确保Python环境已成功配置，参考文档

配置python连接redis:

1.安装Redis的Python包：

使用easy-install安装，关于easy-install的配置，参考以上Python环境的搭建。

[root@njdyw bin]# easy_install2.7.3 redisSearching for redisReading http://pypi.python.org/simple/redis/Reading http://github.com/andymccurdy/redis-pyBest match: redis 2.7.2Downloading http://pypi.python.org/packages/source/r/redis/redis-2.7.2.tar.gz#md5=17ac60dcf13eb33f82cc25974ab17157Processing redis-2.7.2.tar.gzRunning redis-2.7.2/setup.py -q bdist_egg --dist-dir /tmp/easy_install-8FAlft/redis-2.7.2/egg-dist-tmp-JzQViJzip_safe flag not set; analyzing archive contents...Adding redis 2.7.2 to easy-install.pth file Installed /usr/local/python2.7.3/lib/python2.7/site-packages/redis-2.7.2-py2.7.eggProcessing dependencies for redisFinished processing dependencies for redis

安装Parser包（可选）

说明：Parser可以控制如何解析redis响应的内容。redis-py包含两个Parser类，PythonParser和HiredisParser。默认，如果已经安装了hiredis模块，redis-py会使用HiredisParser，否则会使用PythonParser。

HiredisParser是C编写的，由redis核心团队维护，性能要比PythonParser提高10倍以上，所以推荐使用。安装方法，使用easy_install：

[root@njdyw ~]# easy_install2.7.3 hiredisSearching for hiredisReading http://pypi.python.org/simple/hiredis/Reading https://github.com/pietern/hiredis-pyBest match: hiredis 0.1.1Downloading http://pypi.python.org/packages/source/h/hiredis/hiredis-0.1.1.tar.gz#md5=92128474f6fb027cfb8587fce724ea8eProcessing hiredis-0.1.1.tar.gzRunning hiredis-0.1.1/setup.py -q bdist_egg --dist-dir /tmp/easy_install-ZanSCB/hiredis-0.1.1/egg-dist-tmp-XCZBQ0zip_safe flag not set; analyzing archive contents...Adding hiredis 0.1.1 to easy-install.pth file Installed /usr/local/python2.7.3/lib/python2.7/site-packages/hiredis-0.1.1-py2.7-linux-x86_64.eggProcessing dependencies for hiredisFinished processing dependencies for hiredis

2.检查安装是否成功

--easy-install安装的扩展包默认在python的site-packages目录下

[root@njdyw ~]#whereis python2.7.3python2.7: /bin/python2.7.3 /usr/local/python2.7.3[root@njdyw ~]#cd /usr/local/python2.7.3/lib/python2.7/site-packages/[root@njdyw site-packages]# ll
