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。

--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 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 python2.7.3
python2.7: /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

-rw-r--r-- 1 root root 239 03-21 10:45 easy-install.pth
-rw-r--r-- 1 root root 119 03-21 10:07 README

-rw-r--r-- 1 root root 30 03-21 10:12 setuptools.pth
可以看到redis-2.7.2-py2.7.egg包已经成功安装

4.测试实例:
(1).把文本数据导入到redis

--创建命令脚本
[root@njdyw ~]#cat imp_red.py
import redis
import re
pool = redis.ConnectionPool(host='127.0.0.1',port=6379)
r = redis.Redis(connection_pool=pool)
pipe = r.pipeline()
p=re.compile(r'(.*)\s#\s(.*)\s#\s(.*)');
pipe = r.pipeline()
f = open("data.txt")
matchs=p.findall(f.read())
for user in matchs:
key='users_%s' %user[0].strip()
pipe.hset(key,'pwd',user[1].strip()).hset(key,'email',user[2].strip())
pipe.execute()
f.close()
注意:要严格控制python脚本中的空格
