原标题: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:

//www.jb51.net/article/147397.htm

2.确保Python环境已成功配置,参考文档

https://www.jb51.net/article/109765.htm

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

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 http://pypi.python.org/simple/hiredis/
Reading https://github.com/pietern/hiredis-py
Best match: hiredis 0.1.1
Downloading http://pypi.python.org/packages/source/h/hiredis/hiredis-0.1.1.tar.gz#md5=92128474f6fb027cfb8587fce724ea8e
Processing hiredis-0.1.1.tar.gz
Running hiredis-0.1.1/setup.py -q bdist_egg --dist-dir /tmp/easy_install-ZanSCB/hiredis-0.1.1/egg-dist-tmp-XCZBQ0

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.egg
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
