上代码
1、对redis的单实例进行连接操作
python3
>>>import redis
>>>r = redis.StrictRedis(host=‘localhost‘, port=6379, db=0,password=‘root‘)
>>>r.set(‘lufei‘, ‘guojialei‘)
True
>>>r.get(‘lufei‘)
‘bar‘
--------------------
2、sentinel集群连接并操作
[[email protected] ~]# redis-server /data/6380/redis.conf
[[email protected] ~]# redis-server /data/6381/redis.conf
[[email protected] ~]# redis-server /data/6382/redis.conf
[[email protected] ~]# redis-sentinel /data/26380/sentinel.conf &
--------------------------------
## 导入redis sentinel包
>>> from redis.sentinel import Sentinel
##指定sentinel的地址和端口号
>>> sentinel = Sentinel([(‘localhost‘, 26380)], socket_timeout=0.1)
##测试，获取以下主库和从库的信息
>>> sentinel.discover_master(‘mymaster‘)
>>> sentinel.discover_slaves(‘mymaster‘)
##配置读写分离
#写节点
>>> master = sentinel.master_for(‘mymaster‘, socket_timeout=0.1)
#读节点
>>> slave = sentinel.slave_for(‘mymaster‘, socket_timeout=0.1)
###读写分离测试 key
>>> master.set(‘oldboy‘, ‘123‘)
>>> slave.get(‘oldboy‘)
‘123‘
----------------------
redis cluster的连接并操作（python2.7.2以上版本才支持redis cluster，我们选择的是3.5）
https://github.com/Grokzen/redis-py-cluster
3、python连接rediscluster集群测试
使用
python3
>>> from rediscluster import StrictRedisCluster
>>> startup_nodes = [{"host": "127.0.0.1", "port": "7000"}]
### Note: decode_responses must be set to True when used with python3
>>> rc = StrictRedisCluster(startup_nodes=startup_nodes, decode_responses=True)
>>> rc.set("foo", "bar")
True
>>>
‘bar‘
