python 操作redis集群

python的redis库是不支持集群操作的，推荐库：redis-py-cluster，一直在维护。还有一个rediscluster库，看GitHub上已经很久没更新了。


安装

pip3 install redis-py-cluster

 

连接redis集群

from rediscluster import StrictRedisCluster

class RedisCluster(object):  # 连接redis集群
    def __init__(self,conn_list):
        self.conn_list = conn_list  # 连接列表

    def connect(self):

            redisconn = StrictRedisCluster(startup_nodes=self.conn_list, password='123456')

res = RedisCluster(redis_basis_conn).connect()
if not res:
    print("连接redis集群失败")
