Python Redis集群交互

1.安装redis-py-cluster模块

pip install redis-py-cluster

 

2.创建列表,包含所有node节点IP&端口.

 

3. python中导入rediscluster模块, 并使用RedisCluster方法创建实例对象.(旧版本方法名为StrictRedisCluster)

 

 

from rediscluster import RedisCluster
if __name__ == '__main__':
  try:
      # 构建所有的节点，Redis会使⽤CRC16算法，将键和值写到某个节点上
      startup_nodes = [
          {'host': '192.168.1.6', 'port': '7000'},
          {'host': '192.168.1.6', 'port': '7002'},
          {'host': '192.168.1.6', 'port': '7001'},
      ]
      # 构建StrictRedisCluster对象
      src=RedisCluster(startup_nodes=startup_nodes,decode_responses=True)
      # 设置键为name、值为itheima的数据
      result=src.set('name','Jrri')
      print(result)
      # 获取键为name
      name = src.get('name')
      print(name)
  except Exception as e:
      print(e)
