ImportError: No module named redis

在安装过Redis后，通过Python程序导入redis时，遇到一个“ImportError: No module named redis”错误，网上查了下原因，解决办法如下：

Python默认是不支持Redis的，当引用redis时就会报错：

[root@master ~]# python
Python 2.6.6 (r266:84292, Jul 23 2015, 14:41:34)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2

>>> import redis
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named redis
>>> exit()

这里需要为Python安装Redis库，下载 /andymccurdy/redis-py 后，解压并安装：

[root@master soft]# unzip  -d /usr/local/redis
[root@master soft]# cd /usr/local/redis
[root@master redis]# ll
total 4
drwxr-xr-x 7 root root 4096 Nov  4 02:40 redis-py-master
[root@master redis]# cd redis-py-master/
[root@master redis-py-master]# sudo python  install

安装完成后，就可以引用redis库了。

[root@master redis-py-master]# python
