ImportError: No module named redis

在安裝過Redis後，通過Python程序導入redis時，遇到一個“ImportError: No module named redis”錯誤，網上查了下原因，解決辦法如下：

Python默認是不支持Redis的，當引用redis時就會報錯：

[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()

這裏需要爲Python安裝Redis庫，下載https://github.com/andymccurdy/redis-py 後，解壓並安裝：

[root@master soft]# unzip redis-py-master.zip -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 setup.py install

安裝完成後，就可以引用redis庫了。

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