Python连接Redis连接配置

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

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     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
