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

安装

pip install redis-py-cluster

连接集群并操作set

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):
        """
        连接redis集群
        :return: object
        """
        try:
            # 非密码连接redis集群
            # redisconn = StrictRedisCluster(startup_nodes=self.conn_list)
            # 使用密码连接redis集群
            redisconn = StrictRedisCluster(startup_nodes=self.conn_list, password='8Mbh8Ykz')
            return redisconn
        except Exception as e:
            print(e)
            print("错误,连接redis 集群失败")
            return False

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