【redis】python 连接redis的三种方式

1、直连模式

#!/usr/bin/env python  
# -*- coding:utf-8 -*- 

import redis

r = redis.Redis(host='192.168.1.110', socket_connect_timeout=10, port=6379, db=0, password='123456', decode_responses=True)

r = redis.Redis(connection_pool=pool)

print(r.llen('test'))

 

2、哨兵模式

#!/usr/bin/env python  
# -*- coding:utf-8 -*- 


from redis.sentinel import Sentinel

sentinel = Sentinel([('192.168.1.110',16380),
                     ('192.168.1.110', 16381),
                     ('192.168.1.110', 16382)
                     ], socket_timeout=0.5, sentinel_kwargs={'password': '123456'}, db=0)

master = sentinel.master_for('mymaster', password='123456')

slave = sentinel.slave_for('mymaster', password='123456')

print(master.llen('test'))

 

 

3、集群模式

#!/usr/bin/env python  
# -*- coding:utf-8 -*-  


from rediscluster import StrictRedisCluster

redis_nodes = [{'host':'192.168.1.110','port':13790},

{'host':'192.168.1.110','port':13791},

{'host':'192.168.1.110','port':13793},

{'host':'192.168.1.120','port':13794}
]

redisconn = StrictRedisCluster(startup_nodes=redis_nodes,decode_responses=True,password='123456')
