python2.7连接操作redis的几种方法

python版本:2.7
首先需要先安装redis模块:
wget https://pypi.python.org/packages/source/r/redis/redis-2.10.3.tar.gz
tar zxvf redis-2.10.3.tar.gz
cd redis-2.10.3
python setup.py install 
备注：安装方法可以参考INSTALL文件内容
#cat INSTALL
Please use
 python setup.py install
and report errors to Andy McCurdy (sedrik@gmail.com)


然后开始导入redis模块
[root@test ~/python]#python
Python 2.7.12 (default, Jun  1 2018, 14:00:01) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux2

>>> import redis

以下是操作redis的四种方法:
#cat 1.py
#encoding=utf-8   
import redis
r =  redis.StrictRedis(host='localhost', port=6379)
print r.ping()


#cat 2.py
#encoding=utf-8
import redis
r = redis.StrictRedis(host='127.0.0.1', port=6379, db=0)
print r.ping()


#cat 3.py
#encoding=utf-8
import redis
pool = redis.ConnectionPool(host='localhost', port=6379, decode_responses=True)
r = redis.Redis(connection_pool=pool)
print r.ping()


#cat 4.py
# -*- encoding: UTF-8 -*-  
import redis 
r = redis.Redis(host='localhost', port=6379, decode_responses=True)  
print r.ping()
