PS D:\code> 2、利用pip安装指定版本的Redis模块
PS D:\code> pip install redis==4.1.2 #安装指定版本的Redis Requirement already satisfied: redis==4.1.2 in d:\appsoft\python\python310\lib\site-packages (4.1.2)
Requirement already satisfied: packaging>=20.4 in d:\appsoft\python\python310\lib\site-packages (from redis==4.1.2) (21.3)
Requirement already satisfied: deprecated>=1.2.3 in d:\appsoft\python\python310\lib\site-packages (from redis==4.1.2) (1.2.13)

3、利用redis模块连接Redis集群
import logging
from redis import RedisCluster
logging.basicConfig()
logger=logging.getLogger('redis')
logger.setLevel(logging.DEBUG)
logger.propagate=True
r=RedisCluster(host='192.168.102.30',port=7001,password='Aa1111')
print(r.get('test:2')) #nil
print(r.get('BB')) #33
print(r.set('sdlk2','asfdkl'))
print(r.get('sdlk2'))
运行之后输出信息如下：
参考文档：
https://github.com/scredis/scredis/issues/50
scredis {
redis {
# Redis server address
host = "hostname"
# Redis server port
#port = "7387"
password = "redispassword"
# List of hosts or host:port tuples, which serve as seed nodes for a Redis cluster connection.
# If port is missing, the configured port is used as default.
#cluster-nodes = [${scredis.redis.host}":"${scredis.redis.port}]
cluster-nodes = ["hostname1:7385","hostname2:7386","hostname3:7387"]
#cluster-nodes = ${?REDIS_CLUSTER_NODES}
}
