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
主从配置⽂档：
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 redis
Searching for redis
Reading /simple/redis/python安装教程非常详细
Reading github/andymccurdy/redis-py
Best match: redis 2.7.2
Downloading /packages/source/r/redis/redis-2.7.#md5=17ac60dcf13eb33f82cc25974ab17157
Processing redis-2.7.
Running redis-2.7.2/setup.py -q bdist_egg --dist-dir /tmp/easy_install-8FAlft/redis-2.7.2/egg-dist-tmp-JzQViJ
zip_safe flag not set; analyzing
Adding redis 2.7.2 to easy-install.pth file
Installed /usr/local/python2.7.3/lib/python2.7/site-packages/redis-2.7.
Processing dependencies for redis
Finished 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 hiredis
Searching for hiredis
Reading /simple/hiredis/
Reading github/pietern/hiredis-py
Best match: hiredis 0.1.1
Downloading /packages/source/h/hiredis/hiredis-0.1.#md5=92128474f6fb027cfb8587fce724ea8e
Processing hiredis-0.1.
Running hiredis-0.1.1/setup.py -q bdist_egg --dist-dir /tmp/easy_install-ZanSCB/hiredis-0.1.1/egg-dist-tmp-XCZBQ0
zip_safe flag not set; analyzing
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.
Processing dependencies for hiredis
Finished 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 python2.7.3
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
总计 408
-
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 60401 03-21 10:45redis-2.7.
-rw-r--r-- 1 root root 332125 03-21 10:12 setuptools-0.
-rw-r--r-- 1 root root  30 03-21 10:12 setuptools.pth
可以看到redis-2.7.包已经成功安装
3.测试连接
[root@njdyw site-packages]#python2.7.3
Python 2.7.3 (default, Mar 21 2013, 10:06:48)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2

>>>import redis
>>>redisClient=redis.StrictRedis(host='127.0.0.1',port=6379,db=0)
>>> redisClient.set('test_redis','Hello Python')
True
>>> ('test_redis')
>>> print value

>>> redisClient.delete('test_redis')

>>> dir(redis)

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=repile(r'(.*)\s#\s(.*)\s#\s(.*)');
pipe = r.pipeline()
f = open("")
matchs=p.ad())
for user in matchs:
key='users_%s' %user[0].strip()
pipe.hset(key,'pwd',user[1].strip()).hset(key,'email',user[2].strip())
f.close()
注意：要严格控制python脚本中的空格
--执⾏脚本
[root@njdyw ~]# python2.7.3 imp_red.py
查看导⼊数据
