学习目标

• 了解Redis的配置

Python交互

• 安装包如下

  pip install redis-py-cluster

• redis-py-cluster源码地址https://github.com/Grokzen/redis-py-cluster

• 创建⽂件redis_cluster.py，示例码如下

  from rediscluster import *
  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': '192.168.26.128', 'port': '7000'},
            {'host': '192.168.26.130', 'port': '7003'},
            {'host': '192.168.26.128', 'port': '7001'},
        ]
        # 构建StrictRedisCluster对象
        src=StrictRedisCluster(startup_nodes=startup_nodes,decode_responses=True)
        # 设置键为name、值为itheima的数据
        result=src.set('name','itheima')
        print(result)
        # 获取键为name
        name = src.get('name')
        print(name)
    except Exception as e:
        print(e)
